Bathing is the immersion of the body, wholly or partially, usually in water, but often in another medium such as hot air. It is most commonly practised as part of personal cleansing, and less frequently for relaxation or as a leisure activity. Cleansing the body may be solely a component of personal hygiene, but is also a spiritual part of some religious rituals. Bathing is also sometimes used medically or therapeutically, as in hydrotherapy, ice baths, or the mud bath.

People bathe in water at temperatures ranging from very cold to very hot, or in appropriately heated air, according to custom or purpose.

Where indoor heated water is available, people bathe more or less daily, at comfortable temperatures, in a private bathtub or shower. Communal bathing, such as that in hammams, sauna, banya, Victorian Turkish baths, and sentō, fulfils the same purpose, in addition to its often having a social function.

Ritual religious bathing is sometimes referred to as immersion. This can be required after sexual intercourse or menstruation (Islam and Judaism), or as baptism (Christianity).

By analogy, the term "bathing" is also applied to relaxing activities in which the participant "bathes" in the rays of the sun (sunbathing) or in outdoor bodies of water, such as in sea bathing or wild swimming.

Although there is sometimes overlap, as in sea bathing, most bathing is usually treated as distinct from more active recreations like swimming.

History

[edit]

Ancient world

Bathing in ancient China may be traced back to the Shang dynasty, 3000 years ago (1600–1046 BCE).[citation needed] Archaeological findings from the Yinxu ruins show a cauldron to boil water, smaller cauldrons to draw out the water to be poured into a basin, skin scrapers to remove dirt and dead skin.[1] Three 2000-year-old baths with exquisite tiles and a sewage system can be seen in Xi'an.[2][better source needed] Bathing grew in importance in the Han dynasty (202 BC – AD 220) where officials were allowed to take a day's leave for bathing at home every five days, and bathing became the reason for a bank holiday for the first time.[citation needed]

An accountable daily ritual of bathing can be traced to the ancient Indians.[citation needed] They used elaborate practices for personal hygiene with three daily baths and washing. These are recorded in the works called grihya sutras which date back to 500 BCE and are in practice today in some communities. In Hinduism, “Prataha Kaal” (the onset of day) or “Brahma Muhoortham” begins with the 4 am “snanam” or bath, and was considered extremely auspicious in ancient times.[citation needed]

Ancient Greece utilized small bathtubs, wash basins, and foot baths for personal cleanliness. The earliest findings of baths date from the mid-2nd millennium BC in the palace complex at Knossos, Crete, and the luxurious alabaster bathtubs excavated in Akrotiri, Santorini. A word for bathtub, asaminthos (ἀσάμινθος), occurs eleven times in Homer. As a legitimate Mycenaean word (a-sa-mi-to) for a kind of vessel that could be found in any Mycenaean palace, this Linear B term derives from an Aegean suffix -inth- being appended to an Akkadian loan word with the root namsû ('washbowl', 'washing tub'). This luxurious item of the Mycenaean palace culture, therefore, was clearly borrowed from the Near East.[3] Later Greeks established public baths and showers within gymnasiums for relaxation and personal hygiene. The word gymnasium (γυμνάσιον) comes from the Greek word gymnos (γυμνός), meaning "naked".

Ancient Rome developed a network of aqueducts to supply water to all large towns and population centers and had indoor plumbing, with pipes that terminated in homes and at public wells and fountains. The Roman public baths were called thermae. The thermae were not simply baths, but important public works that provided facilities for many kinds of physical exercise and ablutions, with cold, warm, and hot baths, rooms for instruction and debate, and usually one Greek and one Latin library. They also represented an important moment of socialization and exchange between the members of the community.[4] They were provided for the public by a benefactor, usually the Emperor. Other empires of the time did not show such an affinity for public works, but this Roman practice spread their culture to places where there may have been more resistance to foreign mores. Unusually for the time, the thermae were not class-stratified, being available to all for no charge or a small fee. With the fall of the Roman Empire, the aqueduct system fell into disrepair and disuse. But even before that, during the Christianization of the Empire, changing ideas about public morals led the baths into disfavor.

Medieval Japan

[edit]

Before the 7th century, the Japanese were likely to have bathed in the many springs in the open, as there is no evidence of closed rooms. In the 6th to 8th centuries (in the Asuka and Nara periods) the Japanese absorbed the religion of Buddhism from China, which had a strong impact on the culture of the entire country. Buddhist temples traditionally included a bathhouse (yuya) for the monks. Due to the principle of purity espoused by Buddhism these baths were eventually opened to the public. Only the wealthy had private baths.

Onna yu (women's bath) (c. 1780–1790), by Torii Kiyonaga

The first public bathhouse was mentioned in 1266. In Edo (modern Tokyo), the first sentō was established in 1591. The early steam baths were called iwaburo (岩風呂 "rock pools") or kamaburo (釜風呂 "furnace baths"). These were built into natural caves or stone vaults. In iwaburo along the coast, the rocks were heated by burning wood, then sea water was poured over the rocks, producing steam. The entrances to these "bath houses" were very small, possibly to slow the escape of the heat and steam. There were no windows, so it was very dark inside and the user constantly coughed or cleared their throats in order to signal to new entrants which seats were already occupied. The darkness could be also used to cover sexual contact. Because there was no gender distinction, these baths came into disrepute. They were finally abolished in 1870 on hygienic and moral grounds. According to author John Gallagher, bathing "was segregated in the 1870s as a concession to outraged Western tourists".[5]

At the beginning of the Edo period (1603–1868) there were two different types of baths. In Edo, hot-water baths ('湯屋 yuya) were common, while in Osaka, steam baths (蒸風呂 mushiburo) were common. At that time shared bathrooms for men and women were the rule. These bathhouses were very popular, especially for men. "Bathing girls" (湯女 yuna) were employed to scrub the guests' backs and wash their hair, etc. In 1841, the employment of yuna was generally prohibited, as well as mixed bathing. The segregation of the sexes, however, was often ignored by operators of bathhouses, or areas for men and women were separated only by a symbolic line. Today, sento baths have separate rooms for men and women.[6]

Mesoamerica

[edit]
Codex Magliabechiano from the Loubat collection, 1904

Spanish chronicles describe the bathing habits of the peoples of Mesoamerica during and after the conquest. Bernal Díaz del Castillo describes Moctezuma (the Mexica, or Aztec, king at the arrival of Cortés) in his Historia verdadera de la conquista de la Nueva España as being "...Very neat and cleanly, bathing every day each afternoon...". Bathing was not restricted to the elite, but was practised by all people; the chronicler Tomás López Medel wrote after a journey to Central America that "Bathing and the custom of washing oneself is so quotidian (common) amongst the Indians, both of cold and hot lands, as is eating, and this is done in fountains and rivers and other water to which they have access, without anything other than pure water..."[7]

The Mesoamerican bath, known as temazcal in Spanish, from the Nahuatl word temazcalli, a compound of temaz ("steam") and calli ("house"), consists of a room, often in the form of a small dome, with an exterior firebox known as texictle (teʃict͜ɬe) that heats a small portion of the room's wall made of volcanic rocks; after this wall has been heated, water is poured on it to produce steam, an action known as tlasas. As the steam accumulates in the upper part of the room a person in charge uses a bough to direct the steam to the bathers who are lying on the ground, with which he later gives them a massage, then the bathers scrub themselves with a small flat river stone and finally the person in charge introduces buckets with water with soap and grass used to rinse. This bath had also ritual importance, and was vinculated to the goddess Toci; it is also therapeutic when medicinal herbs are used in the water for the tlasas. It is still used in Mexico.[7]

Medieval and early-modern Europe

[edit]

Christianity has always placed a strong emphasis on hygiene.[8] Despite the denunciation of the mixed bathing style of Roman pools by early Christian clergy, as well as the pagan custom of women bathing naked in front of men, this did not stop the Church from urging its followers to go to public baths for bathing,[9] which contributed to hygiene and good health according to the Church Fathers, Clement of Alexandria and Tertullian. The Church also built public bathing facilities that were separate for both sexes near monasteries and pilgrimage sites; also, the popes situated baths within church basilicas and monasteries since the early Middle Ages.[10] Pope Gregory the Great urged his followers on the value of bathing as a bodily need.[11]

Great bathhouses were built in Byzantine centers such as Constantinople and Antioch,[12] and the popes allocated to the Romans bathing through diaconia, or private Lateran baths, or even a myriad of monastic bath houses functioning in the eighth and ninth centuries.[11] The Popes maintained baths in their residences which were described by scholar Paolo Squatriti as "luxurious baths", and bath houses including hot baths were incorporated into Christian Church buildings or those of monasteries, which were known as "charity baths" because they served both the clerics and needy poor people.[13] Public bathing was common in larger towns and cities such as Paris, Regensburg and Naples.[14][15] The Catholic religious orders of the Augustinians and Benedictines had rules for ritual purification,[16] and inspired by Benedict of Nursia encouraged the practice of therapeutic bathing; Benedictine monks played a role in the development and promotion of spas.[17] Protestantism also played a prominent role in the development of the British spas.[17]

Public bathing in Augsburg, by Jörg Breu the Elder, c. 1531

In the Middle Ages, bathing commonly took place in public bathhouses. Public baths were also havens for prostitution, which created some opposition to them. Rich people bathed at home, most likely in their bedroom, as "bath" rooms were not common. Bathing was done in large, wooden tubs with a linen cloth laid in it to protect the bather from splinters. Additionally, during the Renaissance and Protestant Reformation, the quality and condition of the clothing (as opposed to the actual cleanliness of the body itself) were thought to reflect the soul of an individual. Clean clothing also reflected one's social status; clothes made the man or woman.

Due to Black Death plague, introduced from Asia to Europe, public baths were closed to avoid contagion.[18][19][20] In the sixteenth century, the popularity of public bathhouses in Europe sharply declined, perhaps due to the new plague of syphilis which made sexual promiscuity more risky, or stronger religious prohibitions on nudity surrounding the Protestant Reformation.[21][22] Some Europeans came to believe the false idea that bathing or steaming would open pores to disease.[23]

Modern era

[edit]

Therapeutic bathing

[edit]

Hydropathic applications according to Claridge's Hydropathy book.

Public opinion about bathing began to shift in the middle and late 18th century, when writers argued that frequent bathing might lead to better health. Two English works on the medical uses of water were published in the 18th century that inaugurated the new fashion for therapeutic bathing. One of these was by Sir John Floyer, a physician of Lichfield, who, struck by the remedial use of certain springs by the neighbouring peasantry, investigated the history of cold bathing and published a book on the subject in 1702.[24] The book ran through six editions within a few years and the translation of this book into German was largely drawn upon by Dr J. S. Hahn of Silesia as the basis for his book called On the Healing Virtues of Cold Water, Inwardly and Outwardly Applied, as Proved by Experience, published in 1738.[25]

The other work was a 1797 publication by Dr James Currie of Liverpool on the use of hot and cold water in the treatment of fever and other illness, with a fourth edition published not long before his death in 1805.[26] It was also translated into German by Michaelis (1801) and Hegewisch (1807). It was highly popular and first placed the subject on a scientific basis. Hahn's writings had meanwhile created much enthusiasm among his countrymen, societies having been everywhere formed to promote the medicinal and dietetic use of water; in 1804 Professor E.F.C. Oertel of Anspach republished them and quickened the popular movement by the unqualified commendation of water drinking as a remedy for all diseases. [27]

A popular revival followed the application of hydrotherapy around 1829, by Vincenz Priessnitz, a peasant farmer in Gräfenberg, then part of the Austrian Empire.[28] [29] This revival was continued by a Bavarian priest, Sebastian Kneipp (1821–1897), "an able and enthusiastic follower" of Priessnitz, "whose work he took up where Priessnitz left it", after he read a treatise on the cold water cure.[30] In Wörishofen (south Germany), Kneipp developed the systematic and controlled application of hydrotherapy for the support of medical treatment that was delivered only by doctors at that time. Kneipp's own book My Water Cure was published in 1886 with many subsequent editions, and translated into many languages.

Captain R. T. Claridge was responsible for introducing and promoting hydropathy in Britain, first in London in 1842, then with lecture tours in Ireland and Scotland in 1843. His 10-week tour in Ireland included Limerick, Cork, Wexford, Dublin and Belfast,[31] over June, July and August 1843, with two subsequent lectures in Glasgow.[32]

The acceptance of germ theory in the late 1800s provided scientific reasons for frequent bathing.

Public baths and wash-houses

[edit]
Interior of Liverpool wash house, the first public wash house in England

Large public baths such as those found in the ancient world and the Ottoman Empire were revived during the 19th century. The first modern public baths were opened in Liverpool in 1829. The first known warm fresh-water public wash house was opened in May 1842.[13]: 2–14 [33]

The popularity of wash-houses was spurred by the newspaper interest in Kitty Wilkinson, an Irish immigrant "wife of a labourer" who became known as the Saint of the Slums.[34] In 1832, during a cholera epidemic, Wilkinson took the initiative to offer the use of her house and yard to neighbours to wash their clothes, at a charge of a penny per week,[13] and showed them how to use a chloride of lime (bleach) to get them clean. She was supported by the District Provident Society and William Rathbone. In 1842, Wilkinson was appointed baths superintendent.[35][36]

In Birmingham, around ten private baths were available in the 1830s. Whilst the dimensions of the baths were small, they provided a range of services.[37] A major proprietor of bath houses in Birmingham was a Mr. Monro who had had premises in Lady Well and Snow Hill.[38] Private baths were advertised as having healing qualities and being able to cure people of diabetes, gout and all skin diseases, amongst others.[38] On 19 November 1844, it was decided that the working class members of society should have the opportunity to access baths, in an attempt to address the health problems of the public. On 22 April and 23 April 1845, two lectures were delivered in the town hall urging the provision of public baths in Birmingham and other towns and cities.

After a period of campaigning by many committees, the Public Baths and Wash-houses Act received royal assent on 26 August 1846. The act empowered local authorities across the country to incur expenditure in constructing public swimming baths out of its own funds.[39]

The first London public baths was opened at Goulston Square, Whitechapel, in 1847 with the Prince consort laying the foundation stone.[40][41]

Soap promoted for personal cleanliness

[edit]
"The order of the bath" Pears soap advertisement in 1889, a reference to the Order of the Bath. Soap reached a mass market as the middle class adopted a greater interest in cleanliness.

By the mid-19th century, the English urbanised middle classes had formed an ideology of cleanliness that ranked alongside typical Victorian concepts, such as Christianity, respectability and social progress.[42] The cleanliness of the individual became associated with his or her moral and social standing within the community and domestic life became increasingly regulated by concerns regarding the presentation of domestic sobriety and cleanliness. [43]

The industry of soapmaking began on a small scale in the 1780s, with the establishment of a soap manufactory at Tipton by James Keir and the marketing of high-quality, transparent soap in 1789 by Andrew Pears of London. In 1807, Pears found a way of removing the impurities and refining the base soap before adding the delicate perfume of garden flowers, founding Pears soap.[44] It was in the mid-19th century, though, that the large-scale consumption of soap by the middle classes, anxious to prove their social standing, drove forward the mass production and marketing of soap.

William Gossage produced low-priced, good-quality soap from the 1850s. William Hesketh Lever and his brother, James, bought a small soap works in Warrington in 1886 and founded what is still one of the largest soap businesses, formerly called Lever Brothers and now called Unilever. These soap businesses were among the first to employ large-scale advertising campaigns. In 1882, English actress and socialite Lillie Langtry became the poster-girl for Pears soap, and thus the first celebrity to endorse a commercial product.[45][46]

Before the late 19th century, water to individual places of residence was rare.[47] Many countries in Europe developed a water collection and distribution network. London water supply infrastructure developed through major 19th-century treatment works built in response to cholera threats, to modern large-scale reservoirs. By the end of the century, private baths with running hot water were increasingly common in affluent homes in America and Britain.

At the beginning of the 20th century, a weekly Saturday night bath had become common custom for most of the population. A half day's work on Saturday for factory workers allowed them some leisure to prepare for the Sunday day of rest. The half day off allowed time for the considerable labor of drawing, carrying, and heating water, filling the bath and then afterward emptying it. To economize, bath water was shared by all family members. Indoor plumbing became more common in the 20th century and commercial advertising campaigns pushing new bath products began to influence public ideas about cleanliness, promoting the idea of a daily shower or bath.[citation needed]

In the 21st century, challenges to the need for soap to effect such everyday cleanliness and whether soap is needed to avoid body odor appeared in media.[48]

Hot-air baths

[edit]

Hammam

[edit]
Ali Gholi Agha hammam, Isfahan, Iran

A hammam[a] is a type of steam bath or a place of public bathing associated with the Islamic world. It is a prominent feature in the culture of the Muslim world and was inherited from the model of the Roman thermae.[49][50][51] Muslim bathhouses or hammams were historically found across the Middle East, North Africa, al-Andalus (Islamic Spain and Portugal), Central Asia, the Indian subcontinent, and in Southeastern Europe under Ottoman rule.

In Islamic cultures the significance of the hammam was both religious and civic: it provided for the needs of ritual ablutions but also provided for general hygiene in an era before private plumbing and served other social functions such as offering a gendered meeting place for men and for women.[49][50][52] Archeological remains attest to the existence of bathhouses in the Islamic world as early as the Umayyad period (7th–8th centuries) and their importance has persisted up to modern times.[49][52] Their architecture evolved from the layout of Roman and Greek bathhouses and featured a regular sequence of rooms: an undressing room, a cold room, a warm room, and a hot room. Heat was produced by furnaces which provided hot water and steam, while smoke and hot air was channeled through conduits under the floor.[50][51][52]

In a modern hammam visitors undress themselves, while retaining some sort of modesty garment or loincloth, and proceed into progressively hotter rooms, inducing perspiration. They are then usually washed by male or female staff (matching the gender of the visitor) with the use of soap and vigorous rubbing, before ending by washing themselves in warm water.[52] Unlike in Roman or Greek baths, bathers usually wash themselves with running water instead of immersing themselves in standing water since this is a requirement of Islam,[50] though immersion in a pool used to be customary in the hammams of some regions such as Iran.[53] While hammams everywhere generally operate in fairly similar ways, there are some regional differences both in usage and architecture.[52]

Victorian Turkish baths

[edit]
Maud and friends visit a London Turkish bath, 1892

Victorian Turkish baths (inspired by the traditional Islamic bathhouse—the hammam—itself an adaptation of the ancient Roman baths) were introduced to Britain by David Urquhart, diplomat and sometime Member of Parliament for Stafford. He wanted, for political and personal reasons, to popularize Turkish culture in Britain. In 1850 he wrote The Pillars of Hercules,[54] a book about his travels in 1848 through Spain and Morocco. He described the vaporous hot-air baths (little-changed since Roman times) which he visited, both there and in the Ottoman Empire. In 1856 Dr Richard Barter read Urquhart's book and worked with him to construct such a bath, intending to use it at his hydropathic establishment at St Ann(e)'s Hill, near Blarney, County Cork, Ireland.[55] Barter realised that the human body could tolerate the more therapeutically effective higher temperatures in hot air which was dry rather than steamy. After a number of unsuccessful attempts, he opened the first modern bath of this type in 1856. He called it the "Improved" Turkish or Irish bath,[56] now better known as the Victorian Turkish bath.

The following year, the first public bath of its type to be built in mainland Britain since Roman times was opened in Manchester,[57] and the idea spread rapidly. It reached London in July 1860, when Roger Evans, a member of one of Urquhart's Foreign Affairs Committees, opened a Turkish bath at 5 Bell Street, near Marble Arch.[58] During the following 150 years, over 700 Turkish baths opened in the British Isles, including those built by municipal authorities as part of swimming pool complexes. It was claimed by Durham Dunlop (and many others) that hot-air bathing was a more effective body-cleanser than water,[59] while Richard Metcalfe meticulously calculated that it would be more cost-effective for local authorities to provide hot-air baths in place of slipper baths.[60]

Turkish baths opened in other parts of the British Empire. Dr. John Le Gay Brereton opened one in Sydney, Australia in 1859,[61] Canada had one by 1869,[62] and the first in New Zealand was opened in 1874.[63] Urquhart's influence was also felt outside the Empire when in 1861, Dr Charles H. Shepard opened the first Turkish baths in the United States at 63 Columbia Street, Brooklyn Heights, New York, most probably on 3 October 1863.[64]

Purpose

[edit]

One purpose of bathing is for personal hygiene. It is a means of achieving cleanliness by washing away dead skin cells, dirt, and soil and as a preventative measure to reduce the incidence and spread of disease. It also may reduce body odors, however, some people note that may not be so necessary as commonly thought.[48]

Bathing creates a feeling of well-being and the physical appearance of cleanliness.

Bathing may also be practised for religious ritual or therapeutic purposes[65] or as a recreational activity. Bathing may be used to cool or to warm the body of an individual.

Therapeutic use of bathing includes hydrotherapy, healing, rehabilitation from injury or addiction, and relaxation.

The use of a bath in religious ritual or ceremonial rites include immersion during baptism in Christianity and to achieve a state of ritual cleanliness in a mikvah in Judaism. It is referred to as Ghusl in Arabic to attain ceremonial purity (Taahir) in Islam. All major religions place an emphasis on ceremonial purity, and bathing is one of the primary means of attaining outward purity. In Hindu households, any acts of defilement are countered by undergoing a bath and Hindus also immerse in Sarovar as part of religious rites. In the Sikh religion, there is a place at Golden Temple where the leprosy of Rajni's husband was cured by immersion into the holy sacred pool, and many pilgrims bathe in the sacred pool believing it will cure their illness as well.

Types of baths

[edit]

Where bathing is for personal hygiene, bathing in a bathtub or shower is the most common form of bathing in Western, and many Eastern, countries. People most commonly bathe in their home or use a private bath in a public bathhouse. In some societies, bathing can take place in rivers, creeks, lakes or water holes, or any other place where there is an adequate pool of water. The quality of water used for bathing purposes varies considerably. Normally bathing involves use of soap or a soap-like substance, such as shower gel. In southern India people more commonly use aromatic oil and other home-made body scrubs.

Bathing in public can also provide occasions for social interaction, such as in Turkish, banya, sauna, hammams, or whirlpool baths.

Sponge bath

[edit]

When water is in short supply or a person is not fit to have a standing bath, a wet cloth or sponge can be used, or the person can wash by splashing water over their body. A sponge bath is usually conducted in hospitals, which involves one person washing another with a sponge, while the person being washed remains lying in bed.

Ladling water from a container

This method involves using a small container to scoop water out of a large container and pour water over the body, in such a way that this water does not go back into the large container.

In Indonesia and Malaysia, this is a traditional method referred to as mandi.

In the Indonesian language, mandi is the verb for this process; bak mandi is the large container, and kamar mandi is the place in which this is done.[66][67] Travel guides often use the word mandi on its own or in various ways such as for the large container and for the process of bathing.[68][69]

Bathing babies

[edit]

Babies can be washed in a kitchen sink or a small plastic baby bath, instead of using a standard bath which offers little control of the infant's movements and requires the parent to lean awkwardly or kneel.[70] The World Health Organisation recommends only sponge baths until the umbilical cord stump falls off.[71] Bathing infants too often has been linked to the development of asthma or severe eczema according to some researchers, including Michael Welch, chair of the American Academy of Pediatrics' section on allergy and immunology.[72] It's advised that until the baby becomes more mobile, they should only be washed about three times a week.[71] A safe temperature for the bathwater is generally held to be 32–38 °C (90–100 °F).[73]

Japanese bathing culture

[edit]

Private baths

[edit]
Home bathing (1900s), by Kusakabe Kimbei

Although baths at home had been prevalent to some extent since the Edo period (1603-1867), the common people usually went to public bathhouses during the first half of the Showa period (1926-1989), and only wealthy families had their own bathrooms. Home baths became commonplace since the period of rapid economic growth after World War II.[74] Bath water in Japan is much hotter than what is usual in Central Europe. The temperature is usually well above 40 °C (104 °F). In medical literature, 47 °C (117 °F) is considered bearable.[75] The heat is considered a prerequisite for complete relaxation. The custom is to thoroughly clean oneself with soap and rinse before entering the tub, so as not to contaminate the bath water.

Public baths

[edit]

In public baths, there is a distinction between public baths with natural hot springs (called onsen, meaning 'hot'), and those without natural hot springs (known as sento). Since Japan is located in a volcanically active region, there are many hot springs, of which about 2,000 are swimming pools. Most onsen are in the open countryside, but they are also found in cities. In Tokyo, for example, there are about 25 onsen baths. Onsen are similar to Western-style spas in their therapeutic use of natural hot springs.

An onsen consists mostly of outdoor pools (rotenburo), which are sometimes at different temperatures. Extremely hot springs, where even experienced or frequent hot-spring bathers can only stay a few minutes, are called jigoku ('hell'). Many onsen also have saunas, spa treatments and therapy centers. The same rules apply in public baths as in private baths, with bathers required to wash and clean themselves before entering the water. In general, the Japanese bathe naked in bathhouses; bathing suits are not permissible.[citation needed]

Art motif

[edit]

Bathing scenes were already in the Middle Ages a popular subject of painters. Most of the subjects were women shown nude, but the interest was probably less to the bathing itself rather than to provide the context for representing the nude figure. From the Middle Ages, illustrated books of the time contained such bathing scenes. Biblical and mythological themes which featured bathing were depicted by numerous painters. Especially popular themes included Bathsheba in the bath, in which she is observed by King David, and Susanna in the sight of lecherous old men.

In the High Middle Ages, public baths were a popular subject of painting, with rather clear depictions of sexual advances, which probably were not based on actual observations. During the Renaissance and Baroque periods, the gods and nymphs of Greek mythology were depicted bathing in allegorical paintings by artists such as Titian and François Boucher, both of whom painted the goddess Diana bathing. Artists continued to paint Biblical characters bathing, and also sometimes depicted contemporary women bathing in the river, an example being Rembrandt's Woman Bathing.

In the 19th century, the use of the bathing scene reached its high point in classicism, realism and impressionism. Oriental themes and harem and turkish baths scenes became popular. These scenes were based on the artists' imagination, because access by men to Islamic women was not generally permitted.[77] In the second half of the century, artists increasingly eschewed the pretexts of mythology and exoticism, and painted contemporary western women bathing. Edgar Degas, for example, painted over 100 paintings with a bathing theme. The subject of Bathers remained popular in avant-garde circles at the outset of the 20th century.

Bathing is the immersion or application of water, typically with soap or cleansers, to the body for the removal of dirt, sweat, bacteria, and dead skin cells, serving as a fundamental practice of personal hygiene that prevents infections and supports skin health. Emerging in ancient civilizations like Egypt around 1500 BCE as a ritual for spiritual purification, bathing evolved through Roman public thermae for social and therapeutic purposes into modern individualized routines emphasizing cleanliness amid urbanization and germ theory. Empirical evidence indicates regular bathing reduces risks of dermatological conditions and bacterial overgrowth while promoting subjective refreshment and mental relaxation, though excessive frequency can disrupt the skin's natural barrier by depleting sebum. Culturally, practices vary from communal immersion in Japanese onsen or Turkish hammams—often nude and gender-segregated for social bonding—to private Western showers prioritizing efficiency, reflecting differences in water access, climate, and views on nudity and purity. Defining characteristics include its causal role in public health, as inadequate bathing correlates with outbreaks of skin and communicable diseases, yet over-reliance on hot water or harsh soaps has sparked debates on ecological costs and skin microbiome disruption in resource-abundant settings.

Definition and Purposes

Hygiene and Pathogen Control

Bathing mechanically dislodges and rinses away transient microorganisms, accumulated sebum, sweat, dead corneocytes, and environmental contaminants from the skin surface, thereby reducing the load of potential that could otherwise proliferate and cause infections such as or . This process leverages water's solvent properties to dilute and remove soluble residues, while from washing enhances detachment of adherent . The skin's resident , comprising mostly commensal species like , provides a baseline defense against , but transient invaders from , , or contact increase without regular cleansing, as evidenced by higher bacterial counts in unwashed . Soap augments pathogen control through amphipathic molecules with hydrophilic heads that bind and hydrophobic tails that penetrate lipid bilayers of bacterial cell membranes and viral envelopes, fragmenting them and forming micelles that encapsulate for easy rinsing. This emulsification disrupts the of pathogens to , with empirical tests showing plain reduces hand bacterial counts by over 90% via mechanical action alone, without relying on agents. In contrast, antibacterial soaps offer no proven superiority for routine use in preventing community infections, as randomized trials and FDA reviews confirm equivalent to plain in reducing illness transmission. In clinical environments, antiseptic bathing with 2% gluconate (CHG) demonstrably curbs nosocomial by binding to bacterial cell walls and disrupting their integrity, leading to logarithmic reductions in multidrug-resistant organisms (MDROs) like MRSA. A 2013 multicenter trial of daily CHG washcloths in ICU patients reported a 23% decrease in MDRO acquisition and 28% lower hospital-acquired bloodstream rates compared to soap-and-water controls. Similar meta-analyses affirm CHG's role in preventing central line-associated bloodstream , with risk ratios dropping by 20-40% in high-risk cohorts, though benefits diminish in low-prevalence settings due to resistance emergence risks. For general populations, however, such interventions exceed necessity, as community relies on targeted washing of high-risk areas like hands and to avert fecal-oral pathogens without broad-spectrum disruption. Optimal bathing frequency balances removal against preservation of the skin barrier, as excessive washing—particularly with hot water and harsh —strips sebaceous and alters diversity, fostering overgrowth of opportunistic pathogens like . Longitudinal studies link high-frequency to reduced and elevated pathogenic genera, correlating with and susceptibility via impaired barrier integrity. Clinical guidelines recommend 2-3 full-body baths weekly for adults with low , increasing to daily for those in sweaty or soiled conditions, as over-cleansing induces xerosis that cracks the , permitting bacterial ingress. Empirical data from dermatological cohorts show that infrequent bathing elevates cutaneous odds by 1.5-2-fold in unhygienic populations, underscoring bathing's causal role in prevention when calibrated to empirical needs rather than cultural excess.

Therapeutic and Psychological Benefits

Hydrotherapy, the therapeutic use of water immersion, provides physical benefits including alleviation of muscle pain and joint stiffness via buoyancy, which reduces gravitational load on the body, and hydrostatic pressure, which enhances circulation. A review of scientific literature indicates hydrotherapy improves immunity, manages chronic pain, and supports cardiovascular function in conditions such as congestive heart failure and myocardial infarction by decreasing heart rate and blood pressure. Balneotherapy, involving baths in mineral or thermal waters, demonstrates efficacy in reducing inflammation and symptoms of musculoskeletal disorders, with meta-analyses confirming benefits for chronic inflammatory conditions. Warm baths post-exercise promote muscle recovery by increasing blood flow, relaxing tense muscles, and reducing soreness, outperforming cold immersion in preserving muscle power output in some studies. These effects stem from heat-induced and improved lymphatic drainage, contributing to decreased and enhanced mobility. Cold immersion, conversely, facilitates positive adaptations by modulating markers and immune responses, with short-term exposure showing time-dependent reductions in pro-inflammatory cytokines. Psychologically, bathing induces relaxation through activation, lowering stress hormones like and improving overall . Warm baths taken 1-2 hours before , at temperatures of 40-42.5°C, significantly enhance quality by promoting core body temperature regulation conducive to sleep onset, as evidenced by systematic reviews and meta-analyses. and interventions reduce symptoms of anxiety and depression in adults, with randomized controlled trials supporting their role in psychosocial enhancement and mood stabilization. Emerging evidence on cold water immersion suggests benefits for via neurohormesis, where brief physiological stress primes adaptive responses, potentially alleviating depressive symptoms and boosting resilience, though long-term effects require further validation beyond short-term observations. These psychological gains are attributed to endorphin release and modulation, but claims of profound transformations remain preliminary, with some reviews noting limited evidence for sustained immune or performance enhancements.

Social and Cultural Roles

Public baths in ancient Rome functioned as vital social and political centers, where citizens from diverse classes mingled naked, engaging in discussions on philosophy, news, and governance. Thermae, such as Emperor Diocletian's complex accommodating 3,600 bathers, were constructed by rulers to secure public favor and hosted informal senatorial debates influencing imperial decisions. In Ottoman , hammams evolved from Roman precedents into communal spaces emphasizing relaxation, equality, and gender-segregated socialization, particularly for women who used them for grooming, conversation, and marking events like weddings. These baths integrated spiritual purification, aligning with Islamic ablution requirements before , as mandated in the Qur'an. Japanese sento and traditions promote "naked association" (), fostering community bonds and social leveling across hierarchies through shared nudity and hygiene s, a practice rooted in Buddhist-influenced bathing from the . Religiously, bathing holds significance for purification; Hindus immerse in the River to cleanse spiritual impurities, a custom detailed in ancient texts like the Grihya Sutras requiring thrice-daily baths before ceremonies. In , full-body ensures cleanliness for acts like prayers. Culturally, bathing norms reflect status and propriety: Romans flaunted private hypocaust-heated baths as symbols of , while access democratized ; segregation persists in many traditions to uphold , varying by tolerance in communal settings.

Historical Development

Prehistoric and Ancient Civilizations

Evidence of bathing in prehistoric times is indirect and primarily archaeological, derived from the strategic placement of settlements near water sources such as rivers and hot springs, suggesting early humans engaged in immersion or splashing for and cooling since the . Grooming practices, including the use of materials like or for cleaning, are inferred from tool finds, though no dedicated bathing structures predate settled civilizations. In ancient , bathing emerged as a ritualistic practice by around 3000 BCE, often linked to purification rites documented in texts like the bīt rimki incantations, which describe ablutions in dedicated bath-houses to ward off impurities. Elite residences featured private bathrooms with drains, indicating routine washing, while soap-like mixtures of fats, oils, and ashes—evidenced in clay tablet recipes from 2800 BCE—facilitated cleansing beyond alone. Ancient Egyptian bathing, from circa 2000 BCE, emphasized daily immersion for both and religious purity, with elites using stone basins or standing under poured water in palace shower rooms equipped with drains. Commoners typically bathed in the River, applying —a natural soda ash—for scrubbing and deodorizing, as depicted in reliefs and supported by residue analyses on artifacts. The Indus Valley Civilization, flourishing around 2500 BCE, constructed advanced public bathing facilities, most notably the at —a watertight tank measuring approximately 12 by 7 meters, accessed via steps and surrounded by changing rooms, likely used for communal ritual immersion given its central citadel location. Private homes included wells and -lined soak pits connected to covered drains, reflecting widespread emphasis on water management for cleanliness. In ancient China during the Shang Dynasty (c. 1600–1046 BCE), bathing involved heated water from cauldrons and skin scrapers for exfoliation, evolving into social rituals by the Zhou Dynasty where officials were mandated to wash every three to five days. Mesoamerican cultures, such as the Maya from around 500 BCE, employed steam baths (temazcal)—domed structures heated with stones and herbs—for purification, healing, and daily hygiene, with intact examples featuring tunnels and altars indicating ritual significance.

Classical Antiquity and Medieval Periods

In ancient Greece, bathing was integrated into daily hygiene and social life, often occurring in gymnasiums where athletes rinsed off after exercise using rudimentary shower systems fed by aqueducts or springs, a practice dating back to at least the 5th century BCE. Greeks did not use soap but applied olive oil to the skin, scraped it off with a strigil along with dirt and sweat, and sometimes followed with hot water or herbal infusions for cleansing and therapeutic purposes. Public baths, such as tholos structures, emerged by the late Classical period, serving communal and ritual functions tied to physical training and religious purity, though less elaborate than later Roman complexes. Roman bathing culture expanded significantly from Greek precedents, with public balneae proliferating in cities; by 33 BCE, had 170 such facilities, increasing to 856 by the early CE, supported by an extensive aqueduct system delivering millions of cubic meters of daily. , larger imperial complexes like the (construction begun 212 CE under ), featured sequential rooms—, , and —for cold, warm, and hot immersion, combining , exercise, and across social classes, with entry often free or low-cost via state subsidies. These facilities, exemplified by the in Pompeii with its 2nd-century BCE dome, relied on heating and aqueduct-fed pools, accommodating thousands daily and fostering urban cohesion until the empire's decline. Following the fall of the around 476 CE, infrastructure deteriorated due to collapsed aqueducts and , leading to a marked reduction in large-scale , though private and monastic washing persisted. In medieval Christian Europe, full immersion baths became less frequent than daily facial and with basins or rivers, but urban stewes—mixed-sex bathhouses—operated in cities like and into the , serving , medical treatments, and social gatherings, including meals and entertainment. The Church did not prohibit bathing outright, with figures like maintaining palace baths in the and papal endorsements of cleanliness, yet associations of public baths with prostitution and disease, exacerbated by the (1347–1351), contributed to their gradual suppression by the . Islamic regions preserved and advanced Roman-style hammams, influencing via , where bathhouses integrated steam rooms and emphasized ritual purity, but northern Christian practices prioritized simpler, infrequent full baths amid resource scarcity.

Early Modern Europe and Colonial Expansions

In , public bathhouses, which had been widespread in the medieval period, experienced a marked decline starting in the late 15th and 16th centuries, driven by fears of disease transmission—particularly and plague—and moral objections from the associating baths with and idleness. By the mid-16th century, many urban bathhouses were closed; for instance, in , regulations suppressed them by 1546. Full-body immersion bathing became infrequent, occurring perhaps a few times per year for the affluent and even less for commoners, supplanted by partial washing of hands, face, and genitals using basins and ewers. Hygiene practices emphasized dry methods and indirect cleaning: frequent changes of underlinen to absorb sweat and oils, brushing of clothes, application of perfumes and powders, and reliance on natural ventilation rather than water. Therapeutic baths persisted in spa towns like Aachen, where mineral springs drew visitors for health purposes into the 17th century, as evidenced by the Kaiserbad facility operational in 1682. During the Enlightenment in the 18th century, emerging scientific understandings began to promote cleanliness more actively, though full baths remained rare; sponge baths with pitchers became a common morning ritual among the middle classes. European colonial expansions from the 16th to 18th centuries exported these restrained bathing habits to the , , and , often contrasting sharply with indigenous practices. In , Puritan settlers arriving in the early , such as those at Plymouth in 1620, avoided frequent bathing, viewing it as risky for opening pores to illness, and prioritized linen changes instead; Native Americans, who bathed regularly in rivers and streams, reportedly urged colonists to do likewise but met resistance. On transoceanic voyages during the Age of Sail, hygiene was minimal due to ; sailors conducted rudimentary washes over the side or with saltwater, with full immersion virtually impossible on long expeditions. In , European traders and administrators in and from the onward encountered local cultures with daily bathing norms using rivers or household tubs, yet maintained their own infrequent routines, sometimes adapting minimally with local waters for therapeutic ends. Colonial administrations later introduced European-style production and use to indigenous populations, framing it as civilizing , though empirical evidence shows pre-colonial societies often exceeded Europeans in water-based cleaning frequency. These practices reflected causal links between limited water infrastructure, humoral medical theories fearing water's penetration of the skin, and resource constraints in new territories, rather than deliberate neglect.

Industrial Era and 20th Century Modernization

![1914 INTERIOR_OF_UPPER_FREDERICK_STREET_WASH_HOUSE.jpg][float-right] The Industrial Revolution's rapid urbanization in , particularly Britain, exacerbated sanitation challenges, with overcrowded cities fostering epidemics such as outbreaks in 1831-1832 and 1848-1849 that killed tens of thousands. These conditions prompted the sanitary reform movement, emphasizing cleanliness to combat disease, as articulated in Edwin Chadwick's 1842 report linking poor to mortality rates up to 23 percent higher in unsanitary areas. In response, the Public Baths and Wash-houses Act of 1846 empowered local authorities to construct facilities providing affordable access to hot water baths and laundry services for the working classes, who often lacked such amenities at home. By the mid-19th century, over 50 public bathhouses operated in alone, with facilities like Liverpool's St. George's Pier Head baths, established in 1828, serving as precursors that demonstrated bathing's role in . These establishments charged minimal fees, often one penny per bath, and included slipper baths for private immersion alongside communal options, significantly increasing practices among urban poor. The 1848 Public Health Act further institutionalized these efforts by creating local boards of health to oversee sanitation, including improvements essential for bathing. In the United States, similar pressures from industrial growth led to municipal bathhouses in cities like New York by the late , though adoption lagged behind due to decentralized governance. Early 20th-century innovations, such as widespread piped water systems, began transforming private bathing; by 1920, approximately 20 percent of U.S. urban homes had indoor , rising sharply post-World War I with enabling hot water heaters. The interwar and post-World War II periods marked accelerated modernization, with indoor bathrooms becoming standard in new constructions; in Britain, over 80 percent of homes had private baths by 1960, diminishing reliance on facilities. Showers gained prominence for , particularly in contexts during , influencing habits toward daily routines supported by mass-produced soaps and detergents. By mid-century, data correlated these shifts with reduced infectious disease incidence, underscoring bathing's causal role in via empirical declines in typhoid and rates.

Post-2000 Global Shifts

Since 2000, global access to basic facilities enabling regular bathing has expanded dramatically, with the proportion of the world's population using at least basic hygiene services rising from approximately 60% in 2000 to over 70% by 2020, driven by investments in infrastructure under the and subsequent . By 2024, an additional 1.6 billion people had gained access to basic hygiene services since 2015, increasing coverage to 80%, though disparities persist in rural and low-income regions where and inadequate still limit bathing practices. These gains, tracked by WHO and , correlate with reduced waterborne disease incidence, as facilities—such as piped water and private bathing areas—facilitate daily cleansing routines previously unavailable to billions. In developed nations, bathing frequency has faced scrutiny amid emerging dermatological evidence that daily full-body showering disrupts the skin's microbial , which comprises beneficial essential for and resistance. Research since the mid-2000s, including microbiome sequencing studies, indicates that excessive washing with removes sebum and alters bacterial diversity, potentially exacerbating conditions like eczema and dryness, prompting recommendations from experts for 2–3 showers per week focused on high-sweat areas rather than whole-body application. This shift gained traction post-2010, with surveys showing about two-thirds of Americans in 2022 still showering daily due to cultural norms rather than physiological necessity, though younger generations report experimenting with reduced routines influenced by such advice. Environmental pressures have concurrently promoted water-efficient bathing habits, particularly in water-stressed regions, where average shower durations—around 8 minutes in the U.S. as of 2025—contribute significantly to consumption, using up to 17 gallons per session. Behavioral interventions tested since the , such as timed prompts and low-flow fixtures, have achieved persistent reductions in usage by 10–20% without trade-offs, aligning with global goals amid climate-induced scarcity. The from 2020 accelerated targeted —emphasizing handwashing over full immersion—while some individuals adopted less frequent showers due to reduced social exposure, a sustained by roughly 20% of surveyed respondents into 2021. Technological adaptations, including waterless wipes and probiotic sprays mimicking natural skin flora, emerged post-2000 as alternatives for minimalists and travelers, supported by small-scale trials showing odor control without microbial disruption. Overall, these trends reflect a : expanded enabling routine bathing in the Global South versus refined, less resource-intensive practices in affluent areas, grounded in empirical data on and rather than unsubstantiated cultural imperatives.

Methods and Types

Immersive and Wet Bathing Techniques

Immersive bathing entails submerging the body, fully or partially, in a contained volume of , such as a , to facilitate cleansing through prolonged contact and mechanical agitation. The procedure typically begins by filling the tub with warmed to approximately 38–40°C to avoid while promoting comfort and circulation, followed by optional addition of , salts, or oils for enhanced cleaning or conditioning. The bather then enters the tub, uses a washcloth or hands to apply to and extremities, soaks for 10–15 minutes to loosen dirt and dead , and exits to rinse under a separate if needed, thoroughly to prevent moisture-related . Wet bathing techniques, by contrast, apply directly to the body without requiring full submersion, encompassing methods like showering and sponge bathing for targeted or resource-limited cleaning. In showering, the individual stands under a vertical stream of at 37–43°C, wets the body uniformly, applies liquid or bar via hands or a loofah to create lather that emulsifies oils and debris, scrubs affected areas, and rinses to remove residues, with the process lasting 5–10 minutes to achieve comparable microbial reduction to immersion. Sponge bathing, suitable for immobile individuals or , involves soaking a cloth in warm soapy , wringing it to dampness, washing sectionally from cleanest to dirtiest areas (face to ), and patting dry without full rinsing to minimize cross-contamination and skin barrier disruption. Both immersive and wet methods rely on water's solvent properties to dissolve lipids and dislodge particulates, with peer-reviewed comparisons indicating no significant difference in bacterial removal from key sites like the groin when soap is used consistently. Immersive approaches may incorporate additives like Epsom salts for mineral absorption during soaking, while wet variants emphasize sequential wetting, soaping, and rinsing to optimize surfactant action without excessive hydration. Safety protocols across techniques include testing water temperature with the elbow or thermometer to prevent burns, especially for vulnerable populations, and ensuring non-slip surfaces to mitigate fall risks during entry and exit.

Dry and Alternative Cleaning Methods

Dry cleaning methods for personal hygiene involve mechanical or absorptive techniques to remove dirt, dead , and oils from the body without immersion or rinsing, often employed in water-scarce environments, religious rituals, or as supplements to wet bathing. These approaches rely on abrasion, wiping, or powder application to maintain , though their efficacy in fully replacing water-based washing remains limited by the need to physically dislodge debris rather than dissolve or emulsify it. One established dry method is , an Islamic practice substituting for wet ablution () or full bathing () when water is unavailable or harmful, such as during illness, travel, or drought. Performed by striking clean earth, sand, or stone with the palms and wiping the face followed by the hands up to the wrists—starting with the right side—it aims to achieve spiritual purity rather than thorough physical , with one strike of sufficing for both face and hands. Islamic jurisprudence, including scholars like , , and , deems obligatory under such conditions to enable prayer, though it does not equate to the hygienic thoroughness of water washing. Historical dry practices include "dry washing," where individuals wiped the body with clean cloths to remove surface , a method used in ancient societies alongside infrequent full due to resource constraints. In or arid contexts, similar abrasion techniques like rubbing with fine sand or have been documented to exfoliate and absorb oils, as seen in some nomadic or desert-dwelling groups, though these provide superficial without addressing microbial loads deep in skin pores. In modern contexts, dry body brushing uses a stiff-bristled on dry to exfoliate dead cells via mechanical , potentially improving texture and circulation through repeated strokes toward the heart. Dermatological assessments indicate it aids in reducing flaking and promoting superficial blood flow but lacks robust clinical evidence for claims like lymphatic or reduction, with risks including for those with sensitive or compromised barriers. Absorptive alternatives, such as talcum or cornstarch powders, can mitigate sweat and odor by soaking up sebum but do not remove embedded grime and may introduce respiratory concerns if inhaled. Space agencies like employ adapted dry or minimal-liquid for astronauts, including no-rinse wipes or cloths for spot-cleaning, as full use is impractical in microgravity due to and resource limits, emphasizing containment over comprehensive washing. Overall, while dry methods support interim in constrained scenarios, empirical data underscores their role as adjuncts rather than equivalents to water-based cleansing for optimal microbial control and .

Specialized Thermal and Therapeutic Baths

Specialized thermal and therapeutic baths involve immersion in waters with specific mineral compositions, temperatures, or additives to target health conditions, differing from routine hygiene practices by emphasizing physiological responses like vasodilation and mineral absorption. Balneotherapy, a primary form, utilizes natural thermal or mineral springs, where water temperatures typically range from 34–42°C (93–108°F) and contain sulfates, bicarbonates, or radon, applied for durations of 10–20 minutes per session. Mechanisms include hydrostatic pressure reducing edema and thermal effects enhancing circulation, with empirical evidence from controlled trials showing moderate pain relief in osteoarthritis patients after 2–3 weeks of treatment. A 2023 systematic review of 15 randomized trials concluded balneotherapy with thermal mineral water improved Western Ontario and McMaster Universities Osteoarthritis Index scores by 10–15 points compared to controls, though long-term effects remain understudied due to small sample sizes. Hydrotherapy extends these principles through techniques like contrast baths, alternating immersion in hot (38–43°C) and cold (10–15°C) water for 1–3 minutes each over 20–30 minutes, aimed at improving vascular tone and reducing muscle spasms. Peer-reviewed analyses indicate efficacy in managing chronic pain and fibromyalgia, with meta-analyses reporting standardized mean differences of 0.5–0.8 for pain reduction versus no intervention. For instance, in shoulder disorders, hydrotherapy protocols enhanced functional status by 20–30% on visual analog scales after 4–6 weeks, attributed to buoyancy offloading joints and endorphin release. Thermal mineral baths also benefit respiratory conditions; a 2025 review of inhalation and immersion therapies found improved mucociliary clearance and reduced nasal obstruction in chronic rhinosinusitis, with symptom scores dropping 25–40% post-treatment. Pelotherapy, involving mineral-rich mud packs or baths at 40–45°C, leverages peloids—muds matured with seawater or thermal waters containing 20+ minerals like magnesium and silicates—for anti-inflammatory effects. Applications last 15–20 minutes, often followed by mineral water rinsing, and clinical trials demonstrate benefits for rheumatologic disorders, with mud therapy reducing erythrocyte sedimentation rates by 15–20% in osteoarthritis cohorts over 12 sessions. Dead Sea mud, rich in bromide and potassium, exemplifies this, showing dermatological improvements in psoriasis plaques covering <10% body surface area after two-week immersions, via enhanced barrier function and reduced scaling. While these modalities show consistent short-term gains in randomized studies, broader meta-analyses caution that benefits may derive partly from placebo and relaxation, necessitating larger trials for causal attribution beyond correlative data. Contraindications include acute cardiac instability, where thermal stress elevates heart rates by 20–30 beats per minute.

Cultural and Regional Variations

East Asian Bathing Traditions

East Asian bathing traditions, spanning China, Japan, and Korea, prioritize communal hot water immersion for physical cleansing, therapeutic relaxation, and social bonding, often tied to spiritual purification introduced via Buddhism from the 6th century onward. These practices contrast with individualistic Western norms by emphasizing shared spaces where nudity fosters equality and interpersonal trust, with empirical associations to reduced stress through thermal exposure and mineral absorption. In Japan, geothermal onsen springs have been documented for therapeutic use since at least 3,000 years ago, with the Nihon Shoki chronicle of 720 CE recording Emperor Jomei's 8th-century visit to Arima Onsen for skin ailment relief. Public sento bathhouses emerged prominently in the (1603–1868), transitioning bathing from elite privilege—evident in Kamakura-era (1185–1333) private noble baths—to daily communal for urban commoners, often featuring painted murals and gender-segregated hours. By the 19th century, over 500 sento operated in alone, promoting scalding-hot soaks (around 42°C) post-washing to open pores and extract impurities, a method substantiated by historical records amid limited home . This wash-then-soak sequence remains a strict norm in public facilities, with thorough cleaning at individual stations before entering clean tubs, distinguishing Japanese practices from those in Europe or the Middle East. Modern sento and super sento persist, with approximately 2,000 facilities nationwide as of 2020, valued for cardiovascular benefits from alternating heat and air exposure. Japanese bathing culture forms a unique sphere emphasizing immersion for multifaceted purposes, including mental reset and socialization; super sento often integrate over ten bath varieties—such as carbonated, electric, jet, herbal, saunas, and outdoor baths—alongside amenities like dining and relaxation areas, akin to bath theme parks. Prolonged hot soaks, sometimes inducing mild overheating (nobose), are culturally tolerated or valued for invigoration, supported by traditions of extended immersion. A premium is placed on gensen kake nagashi systems delivering unadulterated source water without additives or recirculation. These spaces now serve as stress-relief sanctuaries, evolving from communal hubs to non-daily escapes aiding psychological well-being. Foreign reactions polarize, with some hailing unparalleled relaxation and others noting shock from nudity and variety, recognizing it as ritualistic soft power. Chinese bathing traces to the (c. 1600–1046 BCE), where inscriptions from Yin Ruins describe ritual ablutions using cauldrons and skin scrapers, alongside early urban drainage systems at sites like Dongzhouyang. Daily full immersion was rare; (206 BCE–220 CE) texts indicate wiping with damp cloths or bean-based powders as primary , with government edicts promoting public baths for disease prevention during epidemics.40594-5/fulltext) Buddhist influence post-2nd century CE introduced accessible bathhouses (tangchi), evolving into Tang (618–907 CE) and (960–1279 CE) era complexes with heated pools for the masses, though elite routines involved herbal infusions for skin health, as detailed in medical compendia like the Compendium of Materia Medica (1596).40594-5/fulltext) These practices underscore causal links between infrequent deep cleansing and preservation, avoiding over-stripping of natural oils. Korean traditions center on , modern iterations of Dynasty (1392–1897) mokyoktang public baths, where underfloor heating—dating to the —facilitated dry s (-style) alongside wet tubs for post-harvest purification. Gaining mass appeal in the 1990s, integrate multiple temperature zones (up to 90°C s) with sleeping areas, drawing on Buddhist roots for holistic wellness; a 2023 survey noted over 2,000 facilities serving 20 million annual visitors for via sweat-induced toxin expulsion, corroborated by physiological studies on hyperthermic benefits. Communal norms enforce thorough pre-soak scrubbing with salt or exfoliants, reflecting empirical efficacy in high-density populations. Across these cultures, bathing serves causal health roles—improved circulation from heat , mineral uptake from springs—but social data highlight bonding effects, with linking frequent sento visits to lower isolation rates among elderly. Regional variations persist, yet shared emphasis on preparation (washing before immersion) ensures sanitary communal use, empirically reducing vectors in pre-antibiotic eras.

Middle Eastern and European Bathhouse Cultures

Public bathhouses known as emerged in the during the Umayyad period in the 7th and 8th centuries CE, drawing from Roman, Byzantine, and Central Asian bathing traditions while adapting to Islamic requirements for ritual purity and physical . These baths featured sequential rooms of increasing heat, culminating in a washing area where attendants performed scrubbing and , emphasizing both and spiritual preparation for . In Ottoman society from the 14th to 19th centuries, hammams served as essential social hubs accessible to all classes, where individuals gathered for grooming, relaxation, business discussions, and life events like weddings, fostering community bonds alongside detoxification through heat and water. Their role extended to therapeutic practices, with and aiding circulation and muscle relief, though for specific health claims remains tied to traditional usage rather than modern clinical trials. European bathhouse culture originated with Roman thermae in the 3rd century BCE, evolving into elaborate public complexes that combined hot and cold pools, exercise areas, and social spaces, accommodating thousands daily across the empire until its decline in the 5th century CE. Following the fall of , public bathing persisted in medieval Europe through stewes—mixed-gender houses offering immersion and steaming—but faced gradual decline by the due to associations with disease transmission during plagues like the , alongside shifting medical views favoring dry cleaning over immersion. Bathhouses numbered in the hundreds in cities like and by the , yet moral concerns over and poor led to closures, reducing reliance on communal facilities in favor of private washing. The 19th-century saw a revival of bathhouse traditions in , inspired by Ottoman hammams encountered during colonial expansions, resulting in "Turkish baths" that emphasized dry heat followed by cold plunges for purported invigorating effects. By 1900, over 600 such establishments operated in Britain and , promoting amid urban industrialization and serving as venues for middle-class leisure and therapeutic . This resurgence contrasted with earlier medieval reticence, driven by empirical observations of improved cleanliness in dense populations, though later supplanted by indoor plumbing; surviving examples continue to highlight the enduring appeal of structured, communal bathing for social and restorative purposes.

Indigenous and Non-Western Practices

In North American indigenous cultures, sweat lodges served as central facilities for physical cleansing and spiritual purification, employing heated stones to generate within a dome-shaped enclosure constructed from natural materials like branches and hides. This practice, documented among tribes such as the , , and others north of , facilitated sweating to expel toxins and impurities, often combined with rituals of and herbal infusions for healing ailments ranging from infections to spiritual malaise. Archaeological and ethnographic evidence indicates its prevalence predating European contact, with sessions lasting 45 minutes to hours under leader guidance, emphasizing communal renewal over daily . Among Arctic indigenous groups like the and , steam baths in log or turf structures provided a primary means of cleansing in harsh climates, where limited immersion bathing during winter. These facilities, heated by wood fires or oil lamps to produce vapor from poured water, promoted skin exfoliation through sweat and were used for therapeutic purposes, including treating respiratory issues and maintaining social bonds, with traditions tracing back millennia before Western influence. Historical accounts note infrequent full-body , supplemented by dry rubbing with or oils, reflecting adaptations to subzero temperatures that prioritized survival over frequent water use. In southern African indigenous communities, such as the Himba of , women traditionally eschew bathing to preserve skin oils in arid environments, instead applying a paste of red , , and herbs daily while performing smoke baths by inhaling and wafting embers from aromatic woods like over the body to deter insects and cleanse pores. This method, rooted in pastoralist adaptations to , maintains through antimicrobial smoke properties and ochre's UV-protective qualities, with men permitted occasional river dips; ethnographic observations confirm its efficacy in preventing infections despite minimal use. Polynesian indigenous practices integrated ocean immersion and geothermal soaks for both and purity, as seen in Hawaiian and Māori traditions where saltwater bathing exfoliated skin via mineral-rich waves or tide pools, often preceded by herbal scrubs of and . In regions like , , Māori utilized natural hot springs for medicinal soaks dating to pre-colonial eras, treating skin conditions with sulfurous waters at temperatures around 38–40°C (100–104°F), blending physical cleansing with spiritual renewal tied to ancestral lore. Amazonian indigenous groups, including those in and , incorporated plant-based baths in rituals using infusions of leaves, flowers, and barks from species like guayusa or vines for detoxification and spiritual protection, typically in river settings to combine with ethnobotanical agents that provide effects. These practices, observed in communities like the Yawanawá, emphasize infrequent but intensive sessions over routine washing, leveraging for skin health amid humid conditions.

Health and Hygiene Implications

Empirical Benefits of Regular Cleansing

Regular cleansing removes accumulated dirt, sweat, dead skin cells, and transient microorganisms from the surface, thereby minimizing the proliferation of and fungi that can lead to infections such as , , or . Empirical evidence from interventions demonstrates that consistent bathing practices reduce microbial load on the , with antimicrobial washes further decreasing cutaneous infection rates by 20-50% in high-risk scenarios, such as pre-surgical preparation or in populations prone to recurrent issues. In studies, daily or frequent bathing has been linked to lower incidence of hygiene-related diseases; for instance, a of , , and interventions found that personal hygiene measures, including daily bathing with soap, reduced trachoma prevalence by up to 60% in endemic areas by interrupting the transmission of via facial and body cleansing. Similarly, regular washing disrupts apocrine sweat gland bacteria like and , which metabolize eccrine sweat into volatile compounds responsible for , thereby empirically controlling malodor without reliance on deodorants alone. Beyond infection prevention, routine cleansing supports skin barrier integrity by sloughing off corneocytes and excess sebum, which can otherwise clog pores and exacerbate conditions like acne vulgaris, where studies indicate that twice-daily gentle cleansing reduces counts by 30-50% compared to infrequent washing. In hospital environments, implementing daily gluconate (CHG) bathing protocols has yielded statistically significant reductions in healthcare-associated s, including central line-associated bloodstream infections by 28-53% and overall rates by 23%, underscoring the causal role of microbial reduction through regular antiseptic cleansing. These outcomes hold across diverse populations, provided cleansing avoids harsh agents that could impair the resident microbiome's protective functions.

Risks of Over- and Under-Bathing

Excessive bathing, particularly with hot water or harsh soaps, can strip the skin of its natural oils (sebum) and disrupt the protective barrier, leading to dryness, , and itchiness. This barrier compromise allows and allergens to penetrate more easily, potentially increasing the risk of skin infections or exacerbating conditions like eczema. Prolonged or frequent hot showers exacerbate these effects by further depleting moisture, with dermatologists noting that showers longer than 10 minutes or multiple times daily heighten vulnerability to cracked and subsequent microbial invasion. Conversely, insufficient bathing permits the accumulation of sweat, oils, dead skin cells, dirt, and bacteria on the skin surface. This buildup fosters bacterial overgrowth and can lead to noticeable body odor from bacteria metabolizing sweat, greasy or oily skin, clogged pores potentially resulting in acne or breakouts, skin irritation or itching, and an increased risk of minor skin infections or exacerbation of conditions such as eczema or dandruff. While these effects are generally not dangerous for healthy individuals over a short period such as one week, they can impact personal hygiene, comfort, and social interactions. Poor habits, including infrequent bathing, have been empirically linked to elevated rates of and abscesses in clinical populations, as unremoved pathogens proliferate on the surface. Inadequate cleansing also heightens transmission risks for contagious skin conditions, such as or , by allowing viable pathogens to persist and spread via contact. While individual factors like activity level and influence thresholds, empirical observations indicate that bathing less than twice weekly in sedentary adults correlates with noticeable increases in odor-causing microbial activity and infection susceptibility.

Debates on Frequency and Skin Microbiome

The debate on optimal bathing frequency centers on balancing against the preservation of the 's , which includes , fungi, and other microorganisms that contribute to , immune modulation, and resistance. Frequent washing, particularly with and hot , can deplete sebum and alter microbial composition, potentially leading to reduced diversity and overgrowth of opportunistic pathogens, while infrequent bathing risks accumulation of environmental contaminants, sweat, and metabolic byproducts that foster malodorous or infectious conditions. Dermatological consensus, informed by microbiome research, suggests no universal frequency, with recommendations varying by activity level, , and skin type; for sedentary individuals in temperate environments, bathing two to three times weekly suffices for most, targeting high-sweat areas like axillae and genitals daily if control demands it. Empirical studies indicate that daily full-body showering disrupts the skin microbiome by reducing bacterial biomass and diversity, as soaps and selectively eliminate commensal like while sparing resilient pathogens. A 2021 review in found that everyday cleansing products diminish microbial variety, correlating with increased skin permeability and irritation, effects exacerbated by hot water which further strips . Similarly, UCLA Health research from 2025 highlights immediate adverse shifts post-bathing due to chemical abrasives, linking over-frequent routines to conditions like via microbiome . Proponents of reduced frequency, such as preventive medicine specialist James Hamblin, cite personal experiments and observational data showing stabilized microbial communities and decreased reliance on moisturizers after abstaining from soap-based showers for extended periods, arguing that the skin's self-regulating ecology handles minor accumulations without compromise. Counterarguments emphasize hygiene imperatives, particularly for active or immunocompromised individuals, where under-bathing elevates risks of , , or secondary infections from unchecked proliferation in occluded areas. A CDC notes that while bathing does not sterilize —bacterial counts often rebound or exceed pre-wash levels—it effectively removes transient and allergens, preventing barrier breaches in dry, cracked from over-cleansing. Clinical guidelines from Harvard and Hospitals cap showers at twice daily maximum but stress shorter durations under lukewarm water to minimize disruption, with evidence from longitudinal ICU studies showing antiseptic bathing reduces pathogenic load without long-term microbiome collapse in controlled settings. Emerging data underscores individual variability: microbiome resilience improves with age and , but factors like antibiotics or amplify bathing's disruptive potential, per a 2024 Heliyon review. Recommendations thus prioritize evidence over cultural norms—daily habits rooted in 20th-century campaigns rather than —with experts advocating targeted rinsing over comprehensive soaping to sustain microbial equilibrium while averting and .

Environmental Considerations

Resource Consumption in Bathing

A typical bathtub filled to standard capacity requires 36 to 50 gallons (136 to 189 liters) of , though partial fills for bathing often use around 30 gallons (113 liters) to accommodate the bather. In contrast, showers consume at rates of 2 to 5 gallons per minute (7.6 to 19 liters), yielding 10 to 25 gallons (38 to 95 liters) for an average 5- to 10-minute duration with low-flow heads. Thus, full immersion baths generally demand 1.5 to 3 times more than equivalent showers, amplifying resource intensity for equivalent cleansing. Water heating for bathing exacerbates consumption, as domestic hot water accounts for approximately 18% of total household use , with bathing and showering comprising a substantial share alongside and . Heating 30 of water from an incoming of 50°F (10°C) to 120°F (49°C)—a common or bath target—requires roughly 0.2 to 0.3 kilowatt-hours per gallon depending on system efficiency, translating to 6 to 9 kWh for a single bath using electric resistance heating. Gas or systems reduce this by 20-50% through higher efficiency, but standby losses in storage tanks add 10-20% to daily draw. Globally, personal hygiene including bathing drives 20-30% of household water use in developed regions, with domestic demand surging 600% from 1960 to 2014 amid rising per capita standards. In water-scarce contexts, minimum viable use for washing falls to 20 liters per capita per day per benchmarks, underscoring bathing's disproportionate footprint in affluent settings where showers alone can exceed this by factors of 5-10. Empirical audits confirm that optimizing fill levels and durations cuts bathing-related water by up to 50% without hygiene compromise, though adoption lags due to behavioral inertia.

Sustainability Challenges and Empirical Data

Bathing practices impose notable sustainability burdens through high and demands, exacerbating resource scarcity and in regions reliant on finite supplies or fossil fuel-based heating. In the United States, indoor use for showers and constitutes approximately 17% of total household consumption, with an utilizing 17 gallons based on an 8-minute duration at a standard flow rate of 2.1 gallons per minute. Globally, showering patterns vary, but studies indicate durations of 5-10 minutes per use, leading to annual demands from bathing exceeding 2,000 liters in urban settings with daily habits. In water-stressed areas, such as parts of or the , this equates to 20-30% of municipal supply allocation for personal hygiene, straining aquifers and desalination infrastructure where over-extraction has depleted by up to 20% in some basins since 2000. Energy consumption for heating bathwater amplifies environmental costs, accounting for 15-25% of residential in cooler climates due to the thermal requirements of raising water from ambient to 40-45°C. Empirical assessments show that hot showers emit 0.5-1 kg of CO2 equivalent per minute when heated via gas boilers, with household bathing contributing up to 46% of water-related emissions in such systems. A 2024 study in subtropical regions found that standard showers generate 1.2-1.5 kg CO2e per event, reducible by 20-22% through low-flow heads limiting output to 6.3 liters per minute, highlighting inefficiencies in conventional fixtures that prioritize comfort over . dependence in heating—prevalent in 60% of global households—links these practices to broader climate impacts, including leaks from extraction. Wastewater from bathing introduces persistent pollutants, challenging treatment infrastructures and ecosystems. Domestic , comprising 50-80% of household effluent from showers and baths, carries , phosphates from soaps, and emerging contaminants like and , which evade conventional filtration in 70% of global systems. Over 80% of worldwide domestic discharges untreated into waterways, elevating by 20-50 mg/L from bathing residues and fostering algal blooms that deoxygenate rivers by up to 30% in affected basins. Peer-reviewed analyses confirm that untreated bathing effluents contribute to endocrine-disrupting compounds persisting at 1-10 μg/L downstream, correlating with declines in 15-25% of monitored aquatic . These challenges persist despite technological advances, as aging in developing nations processes only 20-30% of urban effectively, underscoring causal links between unchecked personal volumes and amplified loads.

Strategies for Reducing Impact

Installing low-flow showerheads certified by the EPA's WaterSense program, which limit flow to 2.0 gallons per minute (gpm) or less, can reduce household use by thousands of gallons annually while also lowering energy demands for heating. For instance, an average U.S. family can save approximately 2,700 gallons of and 330 kilowatt-hours of energy per year by replacing standard 2.5 gpm showerheads with efficient models. These devices maintain adequate pressure through aerating technology, ensuring functionality without compromising cleaning efficacy. Reducing shower duration represents a straightforward behavioral adjustment, as an eight-minute shower at standard flow rates consumes about 17-34 gallons, compared to 10-25 gallons for five minutes. Opting for showers over full baths further minimizes consumption, since a typical bathtub requires 36-70 gallons to fill, often exceeding the water used in multiple short showers. Techniques like "navy showers," involving brief wetting, soaping, and rinsing phases with the water off in between, can cut usage by up to 50% relative to continuous flow. Lowering water temperature during showers conserves , as heating accounts for a significant portion of bathing-related or gas use; reducing from hot to warm settings can decrease energy needs without affecting outcomes. Additionally, repairing leaks in shower fixtures prevents wasteful dripping, which can lose up to 10% of household , and pairing these with tankless or efficient water heaters amplifies savings. These measures collectively address the primary environmental burdens of bathing—freshwater depletion and input—yielding measurable reductions in resource footprints.

Technological Advancements in Bathing

The mechanical shower was patented in 1767 by William Feetham, a London stove maker, marking an early technological shift from bucket-based rinsing to pumped water delivery, though its hand-operated pump limited widespread adoption due to physical effort required. In 1868, Benjamin Waddy Maughan invented the first gas-powered instantaneous water heater, known as the Geyser, enabling on-demand hot water for bathing without prior stove heating, which had previously constrained frequency due to labor intensity. Electric water heaters gained popularity around 1889, coinciding with copper tub replacements for wood, facilitating safer and more efficient home bathing as urban plumbing infrastructure expanded in the late 19th century. Advancements in the included tankless electric showers by the , which provided continuous hot without storage tanks, broadening access in regions with variable grid reliability. Low-flow showerheads emerged in the amid concerns, reducing flow rates from typical 5 gallons per minute (GPM) to under 2.5 GPM while maintaining perceived pressure through aerators and technology, yielding empirical savings of up to 50% in household use per the U.S. EPA's WaterSense standards. In 2006, David Malcolm's High Sierra design achieved 1.5 GPM with a sensation equivalent to 2.5 GPM via patented , demonstrating that perceptual engineering can align conservation with user satisfaction without compromising cleansing efficacy. Contemporary innovations integrate digital controls, such as voice-activated fixtures and app-managed smart showers that preset temperatures and monitor usage, reducing scalding risks and enabling precise ; for instance, systems with built-in sensors adjust flow dynamically to minimize . Water-recycling showers, which filter and reuse graywater mid-use, further exemplify sustainability-focused tech, potentially cutting consumption by 70% in prototypes tested for residential viability. These developments, grounded in data rather than unsubstantiated claims, prioritize causal in water delivery and heating, though adoption varies by infrastructure and regulatory mandates like U.S. federal limits since 1992 capping showerheads at 2.5 GPM. Space bathing technologies, such as the compact, low-water shower on in 1973, utilized and minimal rinsing to enable in microgravity, informing compact designs for resource-scarce environments.

Shifts in Practices and Public Health Responses

In the 19th century, amid recurrent cholera epidemics that killed tens of thousands in Europe and North America, public health authorities shifted bathing practices from sporadic to more regular occurrences as part of broader sanitation reforms. Edwin Chadwick's 1842 report on sanitary conditions linked overcrowding, poor drainage, and infrequent personal cleansing to disease transmission, prompting the UK's Public Health Act of 1848, which established local boards of health to promote hygiene infrastructure including public bathhouses. These measures, informed by empirical observations of mortality declines in areas with improved water access, increased bathing frequency from monthly or less to weekly norms by mid-century, particularly among urban working classes who gained access to communal facilities. The advent of indoor plumbing and affordable soap in the late 19th and early 20th centuries further accelerated this trend, with daily bathing becoming commonplace by 1900 in industrialized nations, driven by public health campaigns emphasizing cleanliness to curb tuberculosis and other infections. U.S. and European health boards, responding to data showing reduced infant mortality in households with bathing facilities, mandated hygiene education in schools and workplaces, embedding frequent washing as a preventive norm despite limited direct causation studies at the time. This era's reforms empirically lowered epidemic impacts, as evidenced by London's cholera death rates dropping from 4,000 in 1849 to under 100 by 1871 following sewer and bathhouse expansions. In recent decades, microbiome research has prompted a counter-shift, with guidance moderating enthusiasm for daily showers to avoid disrupting that protect against pathogens and . Studies demonstrate that frequent use of and hot water reduces microbial diversity, potentially increasing eczema and dryness risks, leading dermatologists and agencies like to recommend bathing every 2-3 days for most adults unless visibly soiled. This evidence-based adjustment, contrasting 20th-century overemphasis on daily cleansing, reflects causal insights into , though adoption remains uneven amid cultural habits formed by prior drives. During the , responses prioritized hand over full-body bathing, with WHO and CDC campaigns citing meta-analyses showing handwashing reduced transmission by up to 47% without mandating increased showers, underscoring targeted rather than blanket practices.
