Our circadian rhythms, aka our internal clock, affect myriad essential bodily functions, such as blood pressure, when we sleep, when we wake, when hormones (like melatonin) are released, when we poop, and so on.

Melatonin is key in regulating your body's internal clock, also known as your circadian rhythm, says Andrew Westwood, M.D., a board - certified sleep physician and assistant professor at Columbia University.

Melatonin, known as the sleep hormone, helps regulate other hormones as well as our circadian rhythms — that «internal» clock we all have that determines when we fall asleep and wake.
