Melatonin is a hormone that tells the body it's time to sleep. In people without sleep problems, the body follows a roughly 24-hour biological clock called the circadian rhythm.

As we known that melatonin is essential for good sleep. This unique hormone is produced by the pineal gland located in the middle of the brain and works with the rhythms of the sun. More melatonin is produced when the sun goes down and less melatonin is produced when the sun rises. It heard like amazing story. Adding melatonin to your diet may improve sleep, researchers say.

Melatonin is a hormone produced by the brain in response to darkness. It helps to adjust your circadian rhythm (24-hour internal clock) and sleep. Exposure to light at night will hinder the production of melatonin. Studies have shown that melatonin also plays other important roles in the body beyond sleep. However, these effects have not been fully understood.
