Study: sleep quality, not just duration, tied to disease risk in 95,559-person UK Biobank cohort
PLOS Medicine analysis of wrist-accelerometer data finds more REM and deep sleep linked to lower risk of dozens of diseases, while under 5 hours' total sleep raises risk of 37 conditions.
What to know
- Study of 95,559 UK Biobank participants used wrist accelerometers and a deep-learning algorithm to map sleep stages against risk of over 1,000 health conditions.
- Greater REM sleep was linked to lower risk of 83 diseases (including heart failure, dementia, Parkinson's disease); greater deep sleep to lower risk of 7 conditions including type 2 diabetes.
- Sleeping less than 5 hours total was associated with elevated risk of 37 conditions, while 6-8 hours showed the lowest overall risk.
- As an observational study, the findings show association, not causation, between sleep architecture and disease risk.

Science Media Centre circulates expert reaction to the findings
The Science Media Centre publishes outside experts' commentary on the study's methodology and implications alongside the wider news-outlet pickup of the PLOS Medicine paper.
“The findings provide additional evidence supporting the role of a 6-8 hours' sleep duration as a health safeguard for middle-aged and older adults, likely attributable to more favorable distributions of sleep stages…”

background
Study finds REM sleep tied to lower risk of 83 diseases — The analysis reports greater REM sleep (per interquartile range of 47.6 minutes) associated with lower risk of 83 diseases including heart failure, dementia and Parkinson's disease, while greater deep sleep was linked to lower risk of 7 conditions including type 2 diabetes and major depressive disorder; sleep under 5 hours was linked to higher risk of 37 conditions.
