Study Links Sleep Duration to Biological Aging, Identifies Optimal Sleep Range
A study published in Nature by the MULTI consortium has mapped sleep duration against biological aging clocks, revealing a U-shaped relationship between sleep and biological age gaps. The study found that the healthiest biological aging profiles occur within a sleep range of 6.4 to 7.8 hours per night. Both insufficient and excessive sleep were associated with increased systemic disease risk and biological aging. The research utilized data from the UK Biobank, involving over 500,000 participants, and developed 23 organ-specific biological age gaps using machine learning frameworks.
