Melatonin is a naturally occurring hormone that is produced by the body in response to darkness. It is often prescribed as a sleep aid because it helps people fall asleep and stay asleep.
However, there are some potential negative effects of melatonin use that should be considered before taking it for sleep. First, melatonin can be addictive and cause withdrawal symptoms when discontinued. Second, prolonged use of melatonin may lead to changes in the body's natural sleep rhythm and increase the risk of developing chronic insomnia or other sleep disorders. Additionally, melatonin may have harmful effects on the brain and reproductive system in both men and women.
