Circadian Rhythm

The circadian rhythm is a natural, internal process that regulates the sleep-wake cycle and repeats roughly every 24 hours. This rhythm is controlled by the body's internal clock, which is influenced by external cues such as light and temperature. The circadian rhythm impacts various biological functions, including hormone production, body temperature, and the sleep-wake cycle.

It is important to maintain a regular circadian rhythm to promote overall health and well-being. Disruptions to the circadian rhythm, such as jet lag or shift work, can lead to sleep disturbances, fatigue, and other health issues.
