Scientists have determined which gene in the human body responsible for the duration and quality of sleep.
Experts from the Medical school of Exeter University led the international team of scientists that conducted a large study. Experts studied the genetic data of about 86 thousand people and checked the results by adding another 6 thousand volunteers. All of them for weeks 24 hours a day, wore on their wrist device that continuously recorded the activity level. So the researchers were able to accurately determine the condition of the people during sleep and not to rely only on their own feelings.
In the end, experts have found 47 sites of the genome that are associated with night sleep. 26 of them monitor the quality, and the rest for other systems. However, researchers have identified a rare gene PDE11A. He is responsible not only for sleep time of its carrier but also for its quality.
– Everyone knows that a good night’s sleep – the guarantee of health and good mood. However, the mechanisms of sleep are still poorly understood. But we know that because of the lack of sleep can appear obesity, diabetes and various mental disorders – said the study’s author , Andrew wood.
