Sleeping too little or too much may accelerate biological aging

Sleeping less than six hours or more than eight hours per night is associated with faster biological aging, according to a recent finding. The study links extreme sleep durations to accelerated bodily deterioration. Researchers found that both insufficient and excessive sleep correlate with cellular aging markers, suggesting a U-shaped relationship. The effect appears independent of other lifestyle factors, though the exact biological mechanisms remain under investigation. The findings add to growing evidence that sleep duration plays a key role in long-term health. Experts recommend aiming for seven to eight hours nightly to potentially slow aging processes.
