Melatonin is a hormone that naturally controls the sleep-wake cycle in the body. The melatonin levels sometimes get lower in the people who are suffering from jet lag, stress at work, older adults, and the disorder of sleep-phase delaying. Usually, at the night time when there is dim light than the body sensing the dim light tends to signals serotonin production in the body. Serotonin further secretes melatonin to initiate the sleep time in the body. Melatonin is present in the form of supplementation, and the people suffering from aging, depression, and other sleep-related disorders can use the supplements.
Melatonin supplementation subsequently regulates the sleep-wake cycle and improves the sleep quality in the people. Studies show that in the case of older adults, not only the sleeplessness goes away, but also the morning alertness increases. It is essential to take the prescription for melatonin supplements from your doctor, as the timing and dose are very important. Try to take the supplements two or three hours before going to sleep at night. Also, try to avoid the intake of supplements in the daytime as melatonin delays the circadian rhythms, thus causing dizziness.
