1. circadian

   Circadian refers to the physical, mental, and behavioral changes in living beings that follow a daily cycle - about 24 hours. It comes from the Latin word "circa" meaning "around" and "diem" meaning "day". Commonly, "circadian rhythm" refers to the internal biological clock that regulates sleep-wake cycle, feeding habits, hormone production and other bodily functions in humans, animals and even in plants. These rhythms can be influenced by external factors such as light and temperature.
