What is melatonin for, side effects, how to take

The benefits and harms of melatonin have been clarified relatively recently, the so-called sleep hormone is not yet well understood. Most of the tests of the artificial drug were conducted on animals, the results of tests in humans were about short-term effects. There is no exact data on the long-term effect of taking the substance, but now it is recognized as a harmless dietary supplement.

What is melatonin and what is it for

Melatonin is a hormone produced by the pineal gland. Its quantity affects the quality, quantity of sleep, related processes. The benefits and harms from the presence or absence of a substance are associated with the ability to control the "activity-rest" cycle.

The hormone acts most of all at night, when falling asleep. It is believed that it strengthens the immune system, helps to avoid premature aging. The main beneficial property is improving the quality of sleep, protecting against stress.

There is a theory that it is beneficial as a preventive against cancer. This ability is poorly understood, so you should avoid considering it a cure for cancer.

In addition to correcting the circadian rhythm, melatonin is beneficial for men, eliminating potency problems. The harm of the substance to males is identical to the harm to women.

When and how the hormone is produced

The body produces a substance on a specific schedule. The pineal gland produces melatonin at night, starting at dusk, with a peak at 24:00 and a decline around 4:00 in the morning. This is one of the reasons why early sleep is beneficial.

In order for the beneficial properties of a substance to fully manifest itself, it is produced enough, the following rules must be observed:

  • curtains should be hung opaque, blocking the light of lanterns, city lighting;
  • it is useful to go to bed from 21.00 to 24.00;
  • when you can't go to rest until midnight, it is advisable to dim the light;
  • an hour before bedtime, it is recommended to avoid exposure to computer monitors, e-books, tablets;
  • Before falling asleep, a small cup of cocoa will benefit;
  • when overworked, it is useful to drink tea made from soothing herbs: chamomile, motherwort, valerian and others.

The production mode is designed for an abstract, ideal organism. Individuals may have slightly different internal clocks. The existence of the so-called larks and owls cannot be denied. The mode of activity of the former fully corresponds to the cycle of production of the substance, and of the latter, it differs significantly from the norm. Attempts to artificially correct circadian rhythms will be harmful. It has been noticed that people who are forced to live in an alien cycle are more likely to get sick, irritable and prone to depression.

Important! The generally accepted mode of work, rest is suitable only for the majority, "owls" help to adapt to an alien cycle of "activity-rest" with herbal infusions, low doses of melatonin.

Reviews and opinions of doctors

Egorova Marina, 30 years old, Krasnodar
I avoid prescribing melatonin to children for insomnia. It is best to give natural soothing herbal preparations. The child's body has not yet been formed, it is impossible to predict how a little-studied drug will affect it.
Antropov Pavel, 38 years old, Vladivostok
I did not observe any side effects from taking melatonin, but I prescribe with caution. Adults are preliminarily sent for examination. The reasons for insomnia are not only a lack of this substance.
Smirnova Marina, 54 years old, Orenburg
I prescribe the drug only for the elderly, against insomnia. I think that in other cases it is more expedient to adjust food habits and activity regime. Young people don't need to drink extra pills. Useful properties are not enough reason to load the body.

Patient reviews

Mileeva Angelina, 30 years old, Arkhangelsk
Prescribed melatonin to improve sleep. I took it as prescribed. The result is really better. One of the side effects spoiled the impression a little - periodic dizziness. But the insomnia was gone.
Evseeva Tatiana, 37 years old, Yelabuga
The doctor prescribed the sleep hormone melatonin, in tablets, for insomnia. She showed up after working the night shifts. Sleep after taking it returned to normal, an additional pleasant bonus - I lost a little weight. The figure was fine, but the surprise was pleasant.
Avdeev Oleg, 50 years old, Anadyr
Sleep became worse with age. Complained to the doctor at the physical examination, he prescribed some kind of melatonin. Until I read what it is, I thought - another nonsense. Having learned more, I went to the pharmacy, I drink as prescribed. Now I sleep perfectly.
