Why do some people only need 5 hours to sleep?

May 10, 2020  11:22

Some people only need 5-6 hours to sleep. As it turned out, a certain gene is responsible for the duration of sleep.

It's all about the mutation of the hDEC2 gene, which monitors how much the body should give time for rest and how soon a person should wake up.

Ying-Hui Fu, a professor of neurology at the University of California, believes that most people in the world will have such a mutation in the future, and we will learn how to control our sleep patterns.

However, she does not know what consequences such a mutation has on the general health of a person and whether a small amount of sleep causes harm to the body.

It is believed that from six to eight hours of sleep may sound pretty good for adults.
