Sleep Expand




Melatonin is a natural hormone regulating sleep, produced by the pineal gland, located on the border of the diencephalon and the midbrain. It causes sleepiness during the hours after sunset. Its production can be inhibited by natural or artificial light, as well as stress. The vast majority of adults need 6 to 9 hours’ sleep a day.
