The main time for melatonin synthesis is from 2 am to 3 am, and light shining on the retina will destroy the formation of melatonin, affect the normal neuroendocrine rhythm, and inhibit the secretion of melatonin from the pineal gland. Therefore, when flying around the world, people who need jet lag, night shift workers, and people exposed to artificial light sources at night can take melatonin for a short period of time.

Other studies have also found that the effect of melatonin in helping to fall asleep and regulating the physiological clock may be related to its ability to lower the body's core body temperature (a lower core body temperature before bedtime helps to induce sleepiness and to enter deep sleep more quickly).

As we known that melatonin is essential for good sleep. This unique hormone is produced by the pineal gland located in the middle of the brain and works with the rhythms of the sun. More melatonin is produced when the sun goes down and less melatonin is produced when the sun rises. It heard like amazing story. Adding melatonin to your diet may improve sleep, researchers say.
