Melatonin is a substance produced by the epiphysis that determines the sleep cycle, acting selectively, ie only when and where it is needed.
It regulates the biological clock of our body, informing it of the circadian phases (the rhythm followed through the day).
The circadian rhythms mark all the mental, behavioural and physical changes that happen in a cycle of approximately 24 hours. These changes respond to the light and the darkness in the environment of the organism. The circadian rhythms influence the:
– Sleep cycles
– Release of hormones
– Body temperature
The circadian rhythm is obtained at 3 months of age and the highest levels of melatonin are reached between 12 months and 3 years.
Properties of melatonin
Melatonin is directly related to sleep, but the truth is that it defines other properties:
– Improves the efficiency of the immune system
– Elevates the defenses
– It is antioxidant
– Positively influences the reproductive system
– It reduces possible diseases in advanced ages
– Provides a better quality of life
– Improves the neurological system
Melatonin is found naturally in our body, although it is also possible to obtain it as medicine in necessary cases. The best-known case of melatonin as a medicine is insomnia, but it is also effective in making people sleep that suffer many changes of schedule, for example because of their work or even to alleviate the symptoms of jet lag.
