Even a small lack of night rest can have a disastrous effect on health, according to an Internet publication for girls and women from 14 to 35 years old Pannochka. net Scientists from the University of Pennsylvania established that six hours of sleep a day instead of eight volunteers showed signs of lack of sleep, and the blood levels of substances that are associated with diseases of the cardiovascular system and diabetes. This research was carried out by scientists under the guidance of Professor of Psychiatry Alexandros Vgontzas (Alexandros Vgontzas).

Together with colleagues from the National Institutes of Health, he observed 25 volunteers who agreed to spend 12 days in a sleep study laboratory. The first four days they slept for eight hours, the remaining - for six. After a week of lack of sleep, studies were carried out on the quality of night sleep and sleepiness during the day. Activity of some hormones was also determined and attention was tested. As expected, the sleep of the subjects came faster, they slept deeper, and the results of tests for drowsiness during the day and mindfulness changed for the worse.

In addition, volunteers reported an increase in interleukin-6 levels by 40-60 percent, and in men, in addition, the level of a substance known as tumor necrosis factor increased by 20-30 percent. These compounds are considered markers of inflammation, their level may increase due to trauma. These observations may be considered unfavorable. Scientists noted that women adapted to lack of sleep better.

So at them the phase of deep sleep averaged 70 minutes, while in men - only 40 minutes. At the same time, Professor Vgontsas noted that even a two-hour lack of sleep should be considered a serious problem, and not treat a full-fledged sleep as a pleasant "bonus". But this opinion is shared by many scientists. The results of this study were reported at a meeting of the Society of Endocrinologists, which is held in San Francisco.
