What are the daily rhythms of a person, it is easy to determine by genetic activity in the cells on the surface of the roots of the fallen hair, say Japanese scientists led by Makoto Akashi of the University of Yamaguchi. Using this method, it will be possible to help, for example, patients suffering from sleep disorders, as reported by the Internet publication for girls and women from 14 to 35 years old Pannochka. Net It should be noted that the genes determining the daily rhythms were determined in the 90s. It was discovered that the genetic control of the rhythms of the body is carried out not only in the brain cells, but in the tissues of different organs, RIA Novosti reports..

Recent studies have also proven that these genes in experimental animals are guilty of a set of excess weight, manifestation of signs of depression or impairment of mental functions. And here to understand with the person the Japanese experts hair. Hair roots, hair follicles, contain specific cells, the activity of diurnal genes in which, according to the analysis, accurately repeats the periods of wakefulness of each particular person. So, people waking up earlier than others had a peak of activity of these genes before.

Next, scientists tested how gene activity is affected by sleep disorders. They shifted for three weeks the daily rhythms of sleep in a group of volunteers for four hours. At the same time, the activity of genes shifted only by 2.5 hours. The same displacement was observed in people who work periodically in the night shift. In them, the activity of genes lagged behind the actual activity of the organism for five hours.
