What is melatonin? All about the sleep hormone

It should be known that melatonin is released into the blood vessels. This generally happens during the hours of the night, or when it is dark, that is to say, during the hours of light, the production of this hormone stops. It should be taken into account that melatonin is not a sleeping pill, but asleep stimulant. As this production is activated by darkness, it is important that people with sleep problems do not expose themselves to the light of bulbs and electronic devices before sleeping.

This amino acid is obtained through the consumption of certain foods. Therefore, if you want to improve the quality of rest, it is essential to increase the consumption of foods rich in tryptophan.
