circadian rhythms.
Circadian rhythms are the light-dark cycles that daily govern the rhythmic changes in the behavior of people and animals. A biological clock governs these cycles and repeated disruptions to them can cause illness.
Sleep and wake cycles
Circadian rhythms are a living organisms day/night cycles, daylight interacting with body hormone chemistry.
Not exactly. Circadian rhythms are a subset of diurnal rhythms. Diurnal rhythms reoccur daily and can be circadian and non-circadian. Circadian rhythms can be set by the environment (entrainment), but are not dependent on environment stimulus for continuation (free-running) (ie. hormone secretion). Non-circadian rhythms are responsive to the environment, but still operate on a daily cycle (ie. the process of photosynthesis).
It regulates essential biological rhythms such as day/night cycles.
