Kronobiologi
Kronobiologi (av antik grekiska χρόνος, chrónos, ”tid”, och "biologi") är ett delområde inom biologi där organismers förmåga att mäta och reagera på tidens gång studeras.[1] Det som främst studeras är biologiska rytmer, vilket är periodiska (cykliska) fenomen i levande organismer och deras anpassning till solens och månens cykler.[2]
Kronobiologiska studier inkluderar – men är inte begränsade till – anatomi, fysiologi, genetik, molekylärbiologi och organismers beteende relaterat till biologiska rytmer.[2] Andra aspekter omfattar reproduktion, ekologi och evolution.

Overview of biological circadian clock in humans.
Biological clock affects the daily rhythm of many physiological processes. This diagram depicts the circadian patterns typical of someone who rises early in morning, eats lunch around noon, and sleeps at night (10 p.m.). Although circadian rhythms tend to be synchronized with cycles of light and dark, other factors - such as ambient temperature, meal times, napping schedule and duration, stress and exercise - can influence the timing as well.
