Comfort

Comfort is a state of physical or psychological ease, often characterized by the absence of hardship. Individuals experiencing a lack of comfort are typically described as uncomfortable or in discomfort. A degree of psychological comfort can be achieved by recreating experiences that are associated with pleasant memories, such as engaging in familiar activities, maintaining the presence of familiar objects, and consumption of comfort foods. Comfort is a particular concern in health care, as providing comfort to the sick and injured is one goal of healthcare, and can facilitate recovery. The phrase "comfort zone" is sometimes used to describe a psychological state associated with perceived safety and familiarity. Because of the personal nature of positive associations, psychological comfort is highly subjective.

As a verb, "to comfort" generally denotes the act of providing relief to someone in pain, distress, or sorrow. Where the term is used to describe the support given to someone who has experienced a tragedy, the word is synonymous with consolation or solace. More broadly, comfort may also refer to the enhancement of a person's state of ease in the absence of explicit discomfort. For example, while sitting in a chair may not cause discomfort, the addition of a pillow can increase a person’s perceived physical comfort.

Psychological research has explored various aspects of comfort, suggesting that while individual experiences of comfort are highly subjective, certain patterns have emerged. Commonly studied forms of physical comfort include contact comfort, comfort food, and thermal comfort. These categories have been identified across multiple studies as recurring factors in how individuals perceive and respond to comfort stimuli.

Contact comfort is satisfaction with someone's touch, like a parent's embrace. This is essential to a child's development.

A well-known study by psychologist Harry Harlow investigated the role of contact comfort using infant rhesus monkeys. The monkeys were separated from their biological mothers and provided with two types of surrogate mothers—one made of wire and another covered in soft cloth. Both surrogates provided nourishment through a feeding nozzle. Despite both surrogates meeting the monkeys' nutritional needs, the monkeys showed a clear preference for the cloth-covered surrogate, spending significantly more time with it. This behavior suggested the importance of tactile stimulation and affection in psychological development.

This experiment justified that importance of comfort and warmth for child development. All the monkeys that grew up from the experiment expressed a behavior of aggression and atypical sexual behaviors.

Comfort foods are foods that, when taken, produce feelings of psychological well-being or emotional relief. According to research, these preferences are frequently linked to the individual's eating history and early experiences, including family-cooked meals.

Comfort foods are often selected based on past experiences that evoke positive emotions. For instance, chocolate is frequently identified as a common comfort food, possibly due to its sweet flavor and its cultural association with rewards and celebrations. The time of day also play a role in consuming comfort foods. In one study, only a portion of eating episodes were found to be driven by actual hunger, with routine or social cues serving as primary motivators in many cases.
