Doctors and scientists have long been touting the benefits of sleep for the brain and body. It’s true—sleep is an essential part of maintaining overall well-being. When you are well rested, your mood improves, your stress levels decrease, and you tend to feel more productive.
According to the U.S. Centers for Disease Control and Prevention (CDC), adults need at least seven hours of sleep. For those 65 and older, the CDC recommends between seven and eight hours of sleep each night.
However, experts recommend between one and five milligrams of melatonin for adults, and many pharmacy-sold brands do not have clear dosage labels.
And more, short-term use has not been associated with complications, but the supplement has not been studied for long-term use in adults.
