Most of us know that not getting enough sleep can take a toll on health. But what if sleeping too much isn't ideal either? A major new study published in Nature has found that both too little and too much sleep may be linked to faster biological aging across multiple organs, including the brain, heart, lungs, and immune system.
Researchers analyzed data from nearly 500,000 participants and found that adults who slept between approximately 6.4 and 7.8 hours a night appeared to have the healthiest aging profiles. Those who regularly slept outside that range showed signs of accelerated aging at the molecular level.
