How substantially is way too a great deal sleep?

On average, most people today require someplace concerning seven and nine several hours of slumber each night. But that’s an normal, not a very good-overall health edict.

“As you start to transfer out in either course, there are men and women who involve marginally more and a bit considerably less rest,” suggests Chris Winter season, MD, rest professional, writer of The Rest Answer and The Rested Kid, and co-writer of Precision Nutrition’s Sleep, Pressure Management, and Restoration Coaching Certification.

3. People today who require 13+ hours of sleep

Some persons snooze 14, 17, 24 or far more hours with really minimal interruption, and they nevertheless wake sensation tired.

“If you come across you are a person of these men and women, it could be an sign that there is some thing mistaken with your rest top quality, not always the amount,” Dr. Winter season says. For case in point, rest conditions like rest apnea and insomnia can disrupt rest, causing people to wake sensation unrefreshed.

A wide variety of health and fitness conditions—including epilepsy, Parkinson’s ailment, and depression—can also guide to hypersomnia, which is the inability to remain awake.
