Those who slept less than five hours had the highest odds for 37.This was an observational study, so it can't prove sleep patterns cause disease — only that they're connected. More research is needed to understand why.The study was published Sept. 17 in the journal PLOS Medicine.More informationThe National Sleep Foundation has more on REM sleep.SOURCE: HealthDay TV, Sept. 18, 2026 .What This Means For YouGetting six to eight hours of quality sleep, especially enough REM and deep sleep, is associated with better overall health and a lower risk of many diseases..Sign up for our weekly HealthDay newsletter
