abril 11, 2022

Reconhecemos que a melatonina tem muitos benefícios, especialmente em nossa qualidade de sono., melatonina não pode substituir pílulas para dormir, e não é recomendado para pessoas comuns tomá-lo por muito tempo.

melatonin powderMelatonina, um dos hormônios secretados pela glândula pineal do cérebro, é um “controlado por luz” hormônio com um ritmo circadiano pronunciado. Quando a luz aumenta durante o dia, the secretion of melatonin is inhibited, and people wake up, and when the light decreases at night, the secretion of melatonin increases, and people fall asleep. Portanto, melatonin can regulate the body’s 24-hour circadian rhythm and is closely related to ourbiological clock”. The secretion of melatonin in the human body will reach its peak around the age of 2, and after that, with the increase of age, the secretion of melatonin in the human body will gradually decrease, and at the age of 70, it will be reduced to a quarter of the peak. . Como resultado, older adults are more likely to suffer from sleep problems than younger adults. The level of melatonin in patients with insomnia is usually low. It is safe to take small doses of melatonin for a short period of time, and it is not easy to cause dependence, but this does not mean that it can replace sleeping pills.In addition, melatonin can inhibit the hypothalamus-pituitary-gonadal axis, reduce the content of gonadotropin-releasing hormone, gonadotropin, luteinizing hormone and follicular estrogen, and can directly act on the gonad to reduce androgen, estrogen and progesterone content. That is to say, melatonin can affect fertility, sex, endocrine and other functions.

Melatonin side effects include but are not limited to the following:

1. Affects fertility Melatonin reduces the levels of androgens, estrogens and progesterone. So for women, overuse may cause female infertility, and for men, it can reduce male libido.
2. Affecting mental state Somepowerful sleep capsulescontain melatonin as high as 3mg or more, far exceeding the dose of 0.5mg. This will cause the body to produce drowsiness, tontura, headache and other mental adverse reactions.
3. Affects sleep Since this is a hormone that can be produced by itself, if it is supplemented in excess for a long time, its own production will be reduced, and exogenous melatonin will be eaten more and more, which will eventually lead to dependence and affect sleep.
4. Affecting endocrine After long-term overdose and discontinuation of the drug, its own secretory function may not be fully recovered, resulting in endocrine system disorders.


Então, melatonin only works in 3 situations:
1. Shift workers who work at night and sleep during the day;
2. The sleep time is shifted later, such as those who stay up until the early morning or even dawn to fall asleep;
3. Business travelers who need jet lag.
For general insomniacs, long-term use of melatonin is not recommended. Long-term use of exogenous melatonin may affect its own secretion function. When melatonin is stopped, its own secretory function may not be restored or only partially restored, and it will become dependent on exogenous melatonin, which will aggravate the symptoms of insomnia. Overall, melatonin does more harm than good.
So for people with insomnia, what methods or products can replace melatonin? Actually there are quite a few.
1. Adjusting your diet, trying a light diet, and avoiding eating within two hours before going to bed. Why do this?
Na verdade, it is to reduce the burden on the stomach, help us fall asleep better, and control the midnight snack, so as not to indigestion before going to bed, causing gastrointestinal discomfort, thereby affecting insomnia.
2.Using sleep aids, such as steam eye masks, to create a suitable sleep environment for yourself.
The steam eye mask can eliminate eye fatigue and effectively block the light, because although the light is turned off, there will still be some light that affects our sleep, so wearing the eye mask can block the light and create a sleeping environment for us. Ao mesmo tempo, the steam eye mask can Massaging the eye area is very comfortable and will also help us fall asleep quickly.
