Circadian rhythm is a biological rhythm which is grounded in time. It consists of physical, mental and behavioral changes occurring within roughly 24 hours.

The term circadian comes from the Latin “circa” meaning around and “diem” meaning day. The rhythm or cycle refers to processes which are endogenous and respond to the environment. This is a natural process primarily responding to light and dark and affecting most living things including animals, plants and microbes.
