What does the circadian rhythm provide to the human body?

The circadian rhythm regulates the body's internal clock, influencing sleep-wake cycles, hormone release, and various physiological processes. It helps synchronize bodily functions with the day-night cycle, promoting optimal health and alertness during the day while facilitating restorative sleep at night. Disruptions to this rhythm can lead to sleep disorders, metabolic issues, and negative impacts on overall well-being.
