Melatonin is a hormone that plays an important role in the body’s sleep-wake cycle. When it is dark, the brain makes melatonin to tell the body that it is time to get ready to sleep.

Melatonin is a hormone that doctors sometimes call the sleep hormone. The brain makes melatonin in response to darkness and stops making it under exposure to light.

Many factors can influence how the body produces melatonin. Sleep disorders, working at night, and jet lag are all examples. Furthermore, as people get older, they start to produce less melatonin.
Melatonin supplements work by boosting the levels of this hormone. Their production usually takes place in a lab.
