Goldilocks sleep window tied to slower ageing in half a million people
TL;DR
A large UK Biobank analysis of about 500,000 adults links six-to-eight hours of nightly sleep with slower biological ageing and lower risk of early death and disease, across 23 ageing clocks in 17 organs; sleeping more or less than this window associates with faster ageing, though the study does not prove causation and individual optimum sleep may vary.
