Scientists have found a system that is responsible in the body for the work of sleep

Scientists from Tel Aviv and Bar Ilan Universities in Israel discovered the influence of a specific protein on the mechanisms

sleep.It turned out that along with the accumulation of fatigue during wakefulness, errors in the DNA of brain neurons also accumulate. And the PARP1 protein for DNA repair signals the need for sleep, causing the corresponding state. Discuss

This protein is responsible for the restoration of bonds inDNA chains and "correction" of errors caused by the duration and quality of wakefulness, oxidative stress, ultraviolet light, enzymatic errors and other aggressive factors.

Scientists conducted research based on methodsoptogenetics, radiation and pharmacological drugs. The first experiments were carried out on zebrafish, which, like mammals, need sleep to recuperate. A connection was found between sleep and the PARP1 protein - if the expression of the protein was stimulated, a signal was sent to the brain about the need for sleep; if the protein was blocked, the fish could not sleep.

The minimum sleep time for DNA and strength restoration was also determined - 6 hours.
