Long sleep duration (>8 hours) in older adults is associated with increased mortality, but this risk is primarily explained by underlying health conditions and lifestyle factors rather than inflammation.
If you are an older adult sleeping more than 8 hours, your mortality risk is higher, but this is likely due to underlying health conditions or lifestyle factors rather than the sleep itself. Focus on managing chronic diseases and maintaining a healthy lifestyle rather than restricting sleep.
the mortality risk associated with long sleep was explained predominantly by lifestyle and health status.
Why this rating
Same high-quality cohort data; attenuation analysis clearly separates the mechanisms.
