How much sleep is ideal for healthy ageing? A new study introduces a “Sleep Chart” showing a U-shaped link between sleep duration and biological ageing. Researchers found that both short (<6 hours) and long (>8 hours) sleep are associated with faster ageing and higher risks of diseases like depression and diabetes.
The lowest biological ageing was observed between 6.4 and 7.8 hours of sleep, though this varied by organ and sex. Using advanced imaging and multi-omics data, the study highlights how sleep impacts the whole body. Optimizing sleep duration could be a simple yet powerful way to improve longevity and overall health.
