A major new study has revealed that both too little sleep and excessive sleep may accelerate biological aging, potentially affecting the brain, heart, lungs and nearly every major organ in the body. Scientists found that adults who consistently sleep between 6.4 and 7.8 hours per night showed the healthiest aging patterns compared to those who slept less than six hours or more than eight hours daily.
The research, published in Nature and highlighted by Healthline, analysed data from nearly 500,000 participants in the UK Biobank. Researchers used advanced machine learning tools and “aging clocks” to measure how different organs age biologically rather than chronologically.
How Sleep Affects Biological Aging
Scientists explained that biological age differs from chronological age. While chronological age simply counts the number of years a person has lived, biological age reflects how healthy or worn down the body’s cells and organs actually are.
The study discovered a “U-shaped” relationship between sleep and aging, meaning both extremes were linked to faster aging. Sleeping too little was associated with increased inflammation, poor glucose regulation, weakened immune function and elevated stress hormones, all of which may contribute to quicker cellular deterioration.…Keep reading the full & the viral video now.
