Melatonin

Introduction: What is Melatonin?

Melatonin is a hormone naturally produced by the pineal gland in the brain. It plays a crucial role in regulating sleep-wake cycles, also known as circadian rhythms. Melatonin levels typically rise in the evening, signaling to the body that it is time to sleep, and decrease in the morning, helping to wake us up.
