Sleep and Mortality
Daniel F. Kripke, MD
Poor sleep efficiency (a higher percentage of time in bed spent awake) was also a predictor of mortality, but this measure included the effect of sleep latency.
Without considering sleep latency, sleep maintenance had only a marginal association with mortality.
Surprisingly, the study did not suggest that too little sleep caused increased mortality.
Total sleep time was not a significant hazard predictor, even though 40% of the sample slept less than 6.0 hours in bed.
A marginally significant effect of either high or low rapid eye movement (REM) sleep percentage was also reported.
Because this seems an artificial way of summarizing REM sleep, and other measures of REM sleep were not significant, this effect would need replication.
Indeed, as the authors strongly urge, the entire study needs replication. Perhaps there are other research groups who can find sufficient sleep data already collected to replicate the study.
