Melatonin is a hormone, often called the hormone of darkness, simply because melatonin tells your brain and your body that it's nighttime and that it's time to sleep. Melatonin is naturally produced by your brain, and it's released by a very small gland deep within your brain, called the pineal gland. However, you can also buy melatonin in certain countries, and some people will try to use it as a sleep aid. But melatonin isn't quite as effective as you may think.

[Sleeping with Science]

For example, if you pull together all of the recent scientific studies on sleep and melatonin, which is a technique that we call a meta-analysis, we've discovered that melatonin only increases the speed with which you fall asleep by 3.9 minutes and only increases the quality of your sleep, what we call your sleep efficiency, by just 2.2 percent.
