Answer:
Melatonin is a naturally occurring hormone in the body that helps regulate the sleep cycle. It is produced by the pineal gland in the brain.
Melatonin levels increase and decrease throughout the day. Typically, melatonin levels rise through the evening and stay elevated overnight, allowing a person to sleep. In the morning, the levels drop back, allowing a person to wake up.
