Your body makes more of it when the sun goes down (around 9 pm). But some research shows that blue screen light can interfere with that process. There's a fair amount of evidence that suggests taking melatonin as a supplement can help you fall asleep. What you should know: Melatonin affects people in different ways, and some people have very strong - even allergic - reactions. Others find that it causes unpleasant side effects, such as dizziness, irritability, or feelings of depression. Also, there's not much research about any long-term effects. It's best to only use it once in a while.
