Melatonin - the hormone that regulates the circadian rhythms of humans.It is produced by the pineal gland and regulates many of the body's vital processes, including the adaptation of the sleep-wake cycle when you change time zones.Now this hormone can be taken further in the form of tablets.For example, to cope with insomnia in violation of the "internal clock".
Scientists conducted a study of melatonin effects on the human body.Clinical trials have shown that melatonin adopted for half an hour before bedtime, it helps improve quality only if at this time the body itself does not secrete it.
The test took 36 people between the ages of 18 to 30 years.Before the start of the experiment all the participants for three weeks did not take any medication, did not smoke, and avoid alcohol and caffeine.The subjects went to bed and woke up on a schedule, and t
Then participants were placed in a dark room without a clock, calendar, and other signs of the day and night shifts.In the laboratory, carefully monitored the brain activity and sleep quality tested regularly check the level of melatonin in the blood.
first three days in a dark room, participants were to sleep for 8 hours and stay awake for 16 hours.Then sleep time was reduced to 6 hours and 40 minutes, and wake - up to 13 hours and 20 minutes.That is, in the "night" only 20 hours left in the test instead of 24. Half of the patients in half an hour before sleep took melatonin, the other half a placebo offered.The last three days of the test carried out in a normal 24-hour cycle of sleep and wakefulness change.
results showed that melatonin drugs help only when the hormone is not produced independently.In this case, taking it not only facilitates the process of sleep, but also improves the quality of sleep.However, even with this condition, the artificial hormone can not outperform the melatonin produced by the body.
According to information received, melatonin is produced mainly at night.Happy levels of the hormone secretion is minimal.
It can be concluded that the effect of taking melatonin will be greatest in the daytime, improving naps.
