Circadian light
Circadian rhythms are biological processes that are generated and regulated by a biological clock located in the brain. These biological processes include body temperature, digestion, release of certain hormones, and a person’s wake/sleep cycle. In the absence of external cues, circadian rhythms in humans will run with a period close to, but not exactly 24 hours (in humans, circadian rhythms cycle every 24.2 hours without exposure to light). If a person does not receive enough light, their circadian rhythms become desynchronized with the local day-night cycle.
