melatonin is a hormone secreted by an organ called pineal gland in the brain. Its concentration in plasma decreases during the day and increases at night. It is through this circadian secretion cycle of melatonin that the pineal gland sends & ldquo; Time signal & rdquo;, When night comes, let the brain and body perceive the news that it has become night and can fall asleep, reduce body temperature, pulse and blood pressure, and cause drowsiness. Therefore, melatonin is also known as the natural & ldquo; Sleeping pills & rdquo;. Melatonin can not only improve sleep quality, but also control and affect the secretion of other hormones. It plays an important role in maintaining the function of endocrine system, improving immunity, antioxidation and anti-aging. Let’s take a look with you.
So, how does melatonin secrete in the human body? Melatonin secretion will begin to increase after 14 hours of light stimulation in the morning, and reach the peak after about 16 hours. In other words, the secretion of melatonin is regulated by light, which is inhibited when it is bright and begins to increase after it becomes dark.
therefore, the darker the light in the bedroom during sleep, the better. The darker the light, the more conducive to the secretion of melatonin, and the amount of melatonin secretion will directly affect people’s sleep depth. If melatonin in human body is reduced at night, a series of symptoms such as insomnia, dreaminess, fatigue and forgetfulness will appear, and various diseases will follow.
with the progress of science and technology, the theory that melatonin can reduce body temperature and make people fall asleep has been used in clinical medicine. Melatonin receptor agonists that we may use clinically include remetiamine, temelton, agomelatine, etc. they cannot be taken at the same time with aspirin. These preparations are not sleeping drugs and have no sedative effect. They just help regulate the biological clock and make people sleepy.
clinical studies have shown that melatonin receptor agonists are effective in the treatment of sleep rhythm disorders in patients with dementia related sleep disorders, especially in patients with sunset syndrome. Taking 1mg melatonin 2 hours before going to bed every night can effectively improve the main complaints of sleep disorders in patients with dementia related sleep disorders, shorten the sleep latency, reduce the number of arousals in sleep, and improve sleep efficiency and sleep quality. In addition, melatonin can also be used to treat sleep disorders with sleep rhythm disorders, including sleep problems of the elderly, sleep phase delay syndrome, jet lag syndrome, shift workers and people with endogenous melatonin synthesis disorders such as the blind or brain injury.
melatonin’s function is far more than regulating the circulation of sleep and wakefulness. It also has the effect of regulating blood flow and contracting coronary arteries, but this effect is not applicable to everyone. If people with insufficient blood supply to the heart and depression tendency need to pay attention, melatonin may aggravate their symptoms and should not be taken. Patients with hypertension, rheumatoid diseases and pregnant women should use it with caution. Consult your doctor before using melatonin, and decide whether to use it and how long to use it after determining that there is no negative effect.
in general, use & ldquo; Green melatonin & rdquo;, Use the following to change the population, dosage and time.
2. Do not superstitiously import melatonin products. Melatonin is a kind of health food. Whether it is domestic or imported raw materials, as long as the quality standard is qualified and there is the approval number of health food approved by the Ministry of health, it is a qualified product, and its taking effect is the same.
3. Taking melatonin cannot take aspirin at the same time.
4. It is best not to smoke when taking melatonin, because smoking can destroy melatonin. At the same time, you can’t drink a lot.
5. The health care function of melatonin approved by the Ministry of health only improves sleep function, and the literature reports on other health care functions of melatonin need of further verification.
