Sleep Disorders | Commonly referred to as a natural sleep aid, the use of melatonin has been gaining more popularity around the world. However, melatonin can do much more than help you get a better sleep at night. Research continues to show that melatonin can be beneficial in other aspects of your health as well. With all of its popularity you may be wondering if melatonin can live up to its hype. This article will discuss how useful melatonin really is for sleep disorders as well as its various other health claims.

What is melatonin?

Melatonin is a hormone in the body, and it’s main role is to help regulate sleep. Interestingly, production and release of melatonin in the body is connected to the time of day. During the night when it is dark production increases, and when it is light production decreases. Production of melatonin also decreases with age, which can cause a number of sleep issues such as insomnia. 

Your body generally produces all of the melatonin that you need, but you can easily find melatonin supplements over-the-counter. Research has found that melatonin promotes sleep, and when taken in appropriate amounts is generally safe for short-term use. Some evidence suggest that taking a melatonin supplement may interfere with your body’s natural melatonin production. Note that melatonin may also cause adverse symptoms including nausea, dizziness, headache, and drowsiness. It is important that you treat melatonin supplements like a sleeping pill and take it under your doctor’s supervision.
