Should Neurologists Be Concerned With REM Sleep Quantity?

The association between sleep and overall health and well-being has long been of interest to physicians, researchers, and the general public. At the highest level, a simple U-shaped association between total sleep time and mortality has been described from as early as 1964. Those who sleep approximately 7 hours are at the lowest point in the curve, with the lowest mortality risk. Mortality increases incrementally as one moves in either direction on the curve, with a marked rise for those sleeping less than 4 hours or more than 10 hours. This association holds true for both sexes and across races/ethnicities and continents.
