Sleep habits and early risers can be caused by genetic changes

The results of the study by scientists at the University of California announced on January 11 said that going to bed early and getting up early is due to genetic changes. This phenomenon is called advanced sleep phase syndrome (FASPS).

Scientist Louis J. Ptacek, who led the study, said about 3 out of 10 the world's population has this gene. Conducting experiments on mice, Louis J. Ptacek and colleagues after determining the gene mechanism causing FASPS, transplanted the gene into mice. They found these mice got up and started working 4 to 6 hours earlier than other normal mice, so they slept four to six hours earlier.

Scientists believe that the results of this study will help people to "install" the biological clock in the body and provide drugs to help workers make night shift with a sleep regime. good.

A scientist, a professor of Stanford Medical University (USA), acknowledged the new findings, but he said that there are many other factors affecting sleep and biological clock not regulated by genes. He cited the typical example of people often going to bed earlier and getting up earlier when they get old. This is a natural evolution that is not regulated by genes because the gene does not change with time.
