The hormone melatonin is produced in the brain, the pineal gland or epiphysis. The substance helps to regulate the sleep cycle. The most intensive process of melatonin occurs in the dark, causing thus a person sleepy. Thus hours in serum hormone concentration thirty times greater than during the day. Peak activity of melatonin affects about two in the morning.

Careful analysis of the data Nurses’ Health Study in the United States has allowed doctors from Brigham Women’s Hospital (Boston) found that nearly four hundred women over twelve years (since 2000) developed type II diabetes. For comparison, the data were studied by experts of the same number of participants in the control group, in which all the women were healthy.

According to the study, women with low levels of melatonin onset of diabetes was observed more frequently, whereas ladies normal concentration of melatonin in the body were two times less likely to develop diabetes.

Doctors say that despite the discovery of the connection between diabetes and melatonin, this does not prove the fact of reducing the secretion of the hormone mentioned above, which is caused by a metabolic disorder.

Now researchers are trying to understand whether the increase in the level of melatonin to prevent the development of diabetes, thereby increasing insulin sensitivity.

Previously, experts found that the negative impact on the production of melatonin may have a wrong way of life that involves night shifts, "white nights" light "pollution", etc.
