Sleep less than seven hours a night increases the risk of colds, say US researchers, according to an online edition for girls and women from 14 to 35 years Pannochka. Net Scientists from the University of Carnegie Mellon conducted a study in which it was found that the risk of colds was higher among those who slept less than seven hours compared to those who slept eight or more hours during the night. Experts believe that lack of sleep weakens the immune system and the body's ability to resist viruses. The study was published in the journal Archives of Internal Medicine.

The researchers involved 153 healthy men and women in the experiment, whose average age was 37 years. Participants were asked about how many hours they had slept in the last two weeks. They were then isolated and exposed to rhinovirus, which causes a cold and a cold. During the next five days, volunteers reported any signs of illness, and they also collected samples of mucus from the nose. After 28 days, each patient was taken a blood test in order to see if antibodies were developed to fight infection.

Experts found that the less a person slept, the more he was exposed to colds.

On average, people who slept less than seven hours, were sick five times more often than those who slept for eight or more hours. Scientists argue that there is a direct relationship between the duration of sleep and the functioning of the immune system. Lack of sleep leads to violations of the regulation of the production of substances in the body (hormones, enzymes and t. ) And weakens the immune system, experts believe.
