If you regularly sleep fewer than 6.5 hours—or make a habit of sleeping more than 8 hours—your organs may be aging faster than they should, a recent study warns.
Researchers found that people who sleep outside a narrow window of 6.4 to 7.8 hours show signs of faster organ aging compared with those who stay within that range. These people also faced a higher risk of chronic diseases, including diabetes, heart disease, and depression.
