Side Effects of Melatonin

The pineal glands located in the brain are responsible for producing melatonin. This is an important neurohormone that helps prepare the body for sleeping. In addition, it plays many other roles, such as immune function, sexual function, antioxidant defenses, and the regulation of cortisol, body temperature, and blood pressure. You may take melatonin supplements to improve sleep duration and quality. However, there are some possible side effects that you need to know.


In some cases, melatonin may cause a mild or moderate headache. This suggests that perhaps the body can be sensitive to this substance or you have taken too much. Whenever a new component goes into the body, it is likely to cause an adverse effect. Also, it is known that melatonin is related to the circadian rhythm, which is the timing that may interfere with the sleep cycle. By affecting this cycle, melatonin can make you sleep too much, too little, or falling out of deep sleep. These are all possible triggers of a headache. [1]
