circadian rhythm

Also known as circadian process, GO:0007623, circadian cycle, circadian rhythms, circadian regulation

natural internal process that regulates the sleep-wake cycle

AI overview

Your body has a natural internal clock called a circadian rhythm that controls when you feel sleepy and when you feel awake throughout the day. This rhythm matters because it affects not just your sleep, but also your energy levels, mood, and overall health.

Encyclopedic overview

Features of the human circadian biological clock based on a person who goes to sleep at 10 PM

A circadian rhythm (/sərˈkeɪdiən/), or circadian cycle, is a natural oscillation that repeats roughly every 24 hours. Circadian rhythms can refer to any process that originates within an organism (i.e., endogenous) and responds to the environment (is entrained by the environment). Circadian rhythms are regulated by a circadian clock whose primary function is to rhythmically co-ordinate biological processes so they occur at the correct time to maximize the fitness of an individual. Circadian rhythms have been widely observed in animals, plants, fungi and cyanobacteria and there is evidence that they evolved independently in each of these kingdoms of life.
