UK Biobank Study Links REM Sleep and 6-8 Hour Durations to Lower Risk of 83 Diseases
A large-scale study of 95,559 UK Biobank participants found that higher REM sleep is associated with a reduced risk of 83 diseases, while 6-8 hours of nightly sleep offers the lowest overall disease risk. Deep sleep also lowered risks for seven conditions, including type 2 diabetes, whereas short sleep and irregular patterns increased risks for various disorders. The findings, published in PLOS Medicine, highlight the importance of sleep architecture, not just duration, for long-term health, though causality cannot be established.
