Some people only need 4 hours of sleep at night!

Scientists estimate that it is a mutation of the hDEC2gene that is the cause of this. In fact, this genetic mutation decreases the ideal and usual 7 to 8 hours of sleep to only 4.

People who have this mutation only need this time to spend a long day without feeling fatigue or any other symptoms related to the lack of sleep.
