Have you ever given a thought to your sleep? Or how your body feels tired?
The answer to all these questions lies in one single hormone: melatonin.
Simply put, melatonin is a hormone produced by a small pea-shaped gland, called the pineal gland, deeply seated in the human brain. This gland regulates the rhythmic rest and activity cycle in the human body. Hence, the human body is naturally induced to sleep by virtue of this gland, and in consequence, melatonin.
