Why do some people sleep very little and still be healthy?

Some people can sleep just a few hours, stay healthy and function well, while others need up to 10 hours of sleep a day. feel refreshed.

There are people like the scientist who invented alternating current – Nikola Tesla – who only slept for 2 hours while researching an invention, or the famous inventor Thomas Edison who slept only 5 hours a day.

Most adults need 7-9 hours of sleep per night to maintain healthbut research has found some people can sleep much less without adverse health effects, according to New Zealand’s broadcaster. RNZ.

Inherited by genes

Dr Ying-Hui Fu, Professor of Neurology and a pioneer in sleep research and genetics at the University of California San Francisco (USA), has identified several gene mutation control the amount of human sleep.

Her research revealed that people “naturally sleep less” thanks to a genetic mutation that keeps them healthy even with just four to six hours of sleep a night, according to her research. RNZ.

Professor Fu said people with the gene “naturally low sleep” are “quite rare”. They remain active and healthy despite very little sleep.

To understand how this gene works in the brain, the team used technology gene editing to create mice with a low sleep mutation. They found that the mutant mice slept less, were more physically active, and performed better on maze memory tests than other mice.

People who “naturally sleep little” have an amazing memory

The study also revealed that people with the mutation also have superior memory abilities.

Professor Fu said that some people “naturally little sleep” have really amazing memories, they can speak multiple languages, or hear something just once and never forget it, according to Professor Fu. RNZ.

“While sleeping, the body is still doing many things, like giving energy for the next day or removing toxins that have accumulated in the body…, all of this usually takes 8 hours to complete, but for With these special people, it only takes 4-6 hours”, according to RNZ.
