Circadian rhythm refers to an internal biological clock that regulates physiological and behavioral processes in approximately 24-hour cycles. This rhythm is present in most living organisms and is regulated by the suprachiasmatic nucleus of the hypothalamus in the brain. Suprachiasmatic nucleus also regulates various physiological processes such as hormone secretion, body temperature, and sleep-wake cycle.
