Melatonin is a hormone secreted by the pineal gland of mammals. The secretion of melatonin by human pineal gland has a strong periodic law, with less secretion during the day and more secretion at night, and the secretion of melatonin reaches its peak from 10 to 2 am at night. Generally speaking, the amount of melatonin secreted by normal people will decrease with age. Take young people for example. Normal young people secrete 200pg/ml melatonin at night and 10pg/ml melatonin during the day.
Second, what are the symptoms of melatonin deficiency in the body?
Melatonin is an important hormone responsible for sleep regulation and control of biological clock. The main symptoms of human melatonin deficiency are:
1, insomnia
Melatonin mainly plays a role in promoting sleep in human body. Lack of melatonin may lead to insomnia. Staying up late for a long time will lead to insufficient melatonin secretion. Insomnia and poor sleep quality caused by melatonin deficiency are precursors of neurasthenia, which may lead to physical discomfort and sleep disorders, such as fatigue, low work efficiency and headache.
2, premature aging
Lack of melatonin may lead to premature aging, especially in women. The symptoms of premature aging caused by melatonin deficiency are thinning hair, dry skin, decreased sexual desire and accelerated human aging.
3. Abnormal endocrine glands
Melatonin, as a pineal hormone, not only controls sleep, but also has some influence on other endocrine glands. Melatonin deficiency may lead to hypothyroidism or hyperthyroidism, abnormal renal function, hypopituitarism of anterior pituitary gland and other diseases.
Insufficient secretion of melatonin will directly affect the health and normal life, so many people will supplement melatonin through health care products such as melatonin tablets, but it should be noted that melatonin cannot be supplemented too much, otherwise it will have a negative impact.
Third, what are the hazards of melatonin supplementation?
Melatonin health products can supplement melatonin for the human body, and eating some foods rich in melatonin can also help promote melatonin secretion, but too much melatonin in the body is not a good thing.
1, too much melatonin supplement dose will inhibit the secretion of melatonin, resulting in dependence on melatonin health care products and vicious circle.
2. The hormone secretion of human body is a whole. Excessive secretion of melatonin will inevitably affect the normal secretion of other hormones, leading to endocrine disorders.
3. Excessive supplementation of melatonin may also lead to side effects such as hypothermia, infertility, decreased male physiological desire, menstrual disorder and abnormal blood sugar.
4, too much melatonin will cause people to feel groggy during the day, affecting normal work, study and life.
Therefore, the more melatonin, the better. Pay attention to the amount of supplement.
