Can melatonin cause headaches? The evidence seems to say yes, so let’s go through how to deal with melatonin-induced headaches…
Melatonin is commonly used as an aid for sleeping. But there are people who report experiencing headaches after taking this supplement.

It’s not unusual for people to deal with insomnia sometimes. Maybe you have difficulty falling asleep, or you could find yourself waking up after just a few hours of sleep.
Melatonin is a hormone that’s made by the body naturally. A few hours before bedtime, the level of melatonin in the body automatically increases.
