Sleep is a fundamental and necessary activity to restore our basic physical and psychological balance. Its regulation depends largely on the production of melatonin, a hormone that acts as a sleep inducer and, in addition, is part of the group of signals that regulate the circadian rhythm or biological rhythm.

Lack of sleep and melatonin can affect:

Our health: melatonin promotes the activity and development of immune cells. In addition, it is capable of neutralizing free radicals, activating certain antioxidant enzymes and inhibiting others with prooxidant action, which is why it is crucial for the prevention of oxidative stress and aging. On the other hand, sleep disturbances promote the risk of cardiovascular disease or obesity, among others.
