Too Much Sleep May Age Your Body Faster, New Study Warns

A study of about 500,000 UK Biobank participants found a U-shaped relationship between sleep and biological aging.

Sleeping fewer than 6 hours or more than 8 hours a night was linked to faster aging in organs including the brain, heart, lungs, liver, and immune system.

The healthiest aging patterns were seen at roughly 6.4 to 7.8 hours of sleep per night.

The findings suggest sleep may be a modifiable factor that influences disease risk and how quickly organs age.
