Chronobiology

Chronobiology is a field of biology that examines time-related phenomena in living organisms. These cycles are important in many essential biological processes that occur in a "scheduled" fashion, such as eating, sleeping, mating, hibernating, migration, and cellular regeneration.

The most important rhythm in chronobiology is the circadian rhythm, which refers to the 24-hour daily biological cycle; however, many other important cycles are also studied, including:

Related to, but not part of, chronobiology is the unsubstantiated theory of biorhythms, which are said to be a set of cyclic variations in human behaviour. The theory's basis lies in physiological and emotional cycles. Some people consider it pseudoscience and others protoscience.
