Melatonin
Melatonin is a hormone produced by the pineal gland. It helps regulate the natural sleep-wake cycle.
Light affects how much melatonin your body produces. During the shorter days of winter, your body may make melatonin either earlier or later in the day than usual. This can lead to symptoms of seasonal affective disorder (SAD).
Melatonin supplements may be used to treat SAD, jet lag, and insomnia.
How safe is melatonin?
In most cases, melatonin supplements are safe in low doses. Children and pregnant or nursing women should not take melatonin without talking to a doctor first. Because melatonin makes you feel drowsy, do not drive or operate machinery when you are taking it. Talk to your doctor before using melatonin.
