Nearly 500,000 UK Biobank participants were analyzed in a Nature study that found both short and long sleep tied to faster biological ageing across multiple organs and molecular systems.
The findings point to sleep as more than rest: researchers say nighttime sleep helps the brain clear waste, resets hormones, shifts immune signals, recalibrates metabolism and supports tissue repair.
The study adds large-scale evidence to a broader question in sleep research—whether poor sleep patterns leave a lasting biological trace over years in the brain, heart, liver and other systems.
