Afternoon
Afternoon is the time between noon and sunset or evening. It is the time when the sun is descending from its peak in the sky to somewhat before its terminus at the horizon in the west. In human life, it occupies roughly the latter half of the standard work and school day. In literal terms, it refers to a time specifically after noon.
Afternoon is often defined as the period between noon and sunset. If this definition is adopted, the specific range of time varies in one direction: noon is defined as the time when the sun reaching its highest point in the sky, but the boundary between afternoon and evening has no standard definition. However, before a period of transition from the 12th to 14th centuries, noon instead referred to 3:00 pm. Possible explanations include shifting times for prayers and midday meals, along which one concept of noon was defined—and so afternoon would have referred to a narrower timeframe.
The word afternoon, which derives from after and noon, has been attested from about the year 1300; Middle English contained both afternoon and the synonym aftermete. The standard phrasing was at afternoon in the 15th and 16th centuries, but has shifted to in the afternoon since then. In American English dialects, the word evening is sometimes used to encompass all times between noon and midnight. The Irish language contains four different words to mark time intervals from late afternoon to nightfall; this period is considered mystical. Metaphorically, the word afternoon refers to a relatively late period in the expanse of time or in one's life.
The equivalent of Earth's afternoon on another planet would refer to the time the principal star of that planetary system would be in descent from its prime meridian, as seen from the planet's surface.
Afternoon is a time when the sun is descending from its daytime peak. During the afternoon, the sun moves from roughly the center of the sky to deep in the west. In late afternoon, daylight is particularly bright and glaring, because the sun is at a low angle in the sky. The standard working time in most industrialized countries goes from the morning to the late afternoon or early evening — archetypally, 9:00 am to 5:00 pm — so the latter part of this time takes place in the afternoon. Schools usually let their students out around 3:00 pm during the mid afternoon. In Denmark, afternoon is considered between 1:00 and 5:00 pm.
In diurnal animals, it is typical for blood levels of the hormone cortisol—which is used to increase blood sugar, aid metabolism and is also produced in response to stress—to be most stable in the afternoon after decreasing throughout the morning. However, cortisol levels are also the most reactive to environmental changes unrelated to sleep and daylight during the afternoon. As a result, this time of day is considered optimal for researchers studying stress and hormone levels. Plants generally have their highest photosynthetic levels of the day at noon and in the early afternoon, owing to the sun's high angle in the sky. The large proliferation of maize crops across Earth has caused tiny, harmless fluctuations in the normal pattern of atmospheric carbon dioxide levels, since these crops photosynthesize large amounts of carbon dioxide during these times and this process sharply drops down during the late afternoon and evening.
In humans, body temperature is typically highest during the mid to late afternoon. However, human athletes being tested for physical vigor on exercise machines showed no statistically significant difference after lunch. Owners of factory farms are advised to use buildings with an east–west (as opposed to north–south) orientation to house their livestock, because an east–west orientation generally means thicker walls on the east and west to accommodate the sun's acute angle and intense glare during late afternoon. When these animals are too hot, they are more likely to become belligerent and unproductive.
The afternoon, especially the early afternoon, is associated with a dip in a variety of areas of human cognitive and productive functioning. Notably, motor vehicle accidents occur more frequently in the early afternoon, when drivers presumably have recently finished lunch. A study of motor accidents in Sweden between 1987 and 1991 found that the time around 5:00 pm had by far the most accidents: around 1,600 at 5:00 pm, compared to around 1,000 each at 4:00 pm and 6:00 pm. This trend may have been influenced by the afternoon rush hour, but the morning rush hour showed a much smaller increase. In Finland, accidents in the agriculture industry are most common in the afternoon, specifically Monday afternoons in September.
