Since the discovery of melatonin in 1958, the earliest clinical studies on melatonin’s role in improving depressive symptoms were conducted before it was discovered that melatonin may be useful in improving sleep. In recent years, clinical studies on melatonin have focused on anti-inflammatory related diseases, and more recently melatonin’s role in fighting cancer has become the focus of increasing research.
First of all, to be clear, melatonin itself is not a sleeping pill, but a hormone synthesized by the pineal gland of the brain. It is also known as the nocturnal hormone, and it is an important messenger that helps the body get into night mode.
Current research has found that melatonin secretion has a circadian rhythm, being lower during the day and starting to rise gradually after nightfall, peaking between 23:00 and 3:00 a.m., then dropping sharply before dawn. When the external light is bright, melatonin secretion will be suppressed, when the external light is dim, it will stimulate melatonin secretion, helping us to better enter and maintain a good sleep.
The standard of melatonin use varies around the world, and China currently allows it to be used as a health food ingredient. According to statistics, from 1996 to 2015, China has approved 740 varieties of health care products claiming to improve sleep, and there are 164 melatonin-containing products. It can be said to be the star product of the sleep world.
