Does melatonin help with sleep?

Melatonin (MT) is one of the hormones secreted by the pineal gland of the brain and belongs to the indole heterocyclic group of compounds. Melatonin is a hormone in the body that induces natural sleep, which overcomes sleep disorders and improves sleep quality by regulating natural sleep in humans. Can melatonin help with sleep? Let’s learn more about it in the following article.

Here is a brief introduction to the two causes of insomnia, one is the brain nervous system disorders, there is a part of the brain nerve center used to control brain activity, if this part of the problem, leading to the result is unable to sleep, dreamy, neurasthenia; the other is melatonin secretion is insufficient, melatonin is the whole body sleep signal signal hormone, leading to the result is unable to sleep.

Here are two clear effects of melatonin that are currently defined as most likely to work.

1.shorten the duration of sleep

A study conducted by U.S. scientists analyzed 19 studies involving 1,683 subjects, melatonin had a significant effect in reducing sleep latency and increasing total sleep time, with the average data showing a 7-minute reduction in sleep onset and an 8-minute extension in sleep duration. The effect was better if melatonin was taken for a longer period of time or if the dose of melatonin was increased. The overall sleep quality of patients taking melatonin improved significantly.

2.sleep rhythm disorders

A study conducted in 2002 on melatonin for jet lag regulation, conducted a randomized trial of oral melatonin for airline passengers, airline staff or military personnel, comparing the melatonin group with a placebo group. The results showed that 9 out of 10 experiments showed that bedtime (10:00 pm to 12:00 pm) in the intended area could be maintained even after the flight crew had crossed 5 or more time zones. The analysis also found doses of 0.5 to 5 mg to be equally effective, though there was just a relative difference in effectiveness. The incidence of other side effects was lower.

Of course for other sleep problems such as reduced dreaminess, wakefulness, and neurosis there are some studies that have shown melatonin to be helpful. However, in terms of principle and the progress of current research, the above two effects are more plausible.

The definition of melatonin as an ingredient is somewhere between a nutraceutical (dietary supplement) and a drug, and each country has a different policy. In the United States it is both a drug and a nutraceutical, in China it is a nutraceutical.
