HHS HealthBeat (May 27, 2014)

Problems with sleep, problems with memory

From the U.S. Department of Health and Human Services, I’m Ira Dreyfuss with HHS HealthBeat.

About seven hours a night of sleep is good for adults, and a study indicates some people who get much less or much more can develop memory problems. Researcher Elizabeth Devore of Harvard-affiliated Brigham and Women’s Hospital looked at data on more than 15,000 women in midlife and beyond.

“Women who were sleeping five or fewer hours, or women who were sleeping nine or more hours – their memory performance was worse in later life.”

Devore says women who slept around seven hours a night did better on memory. She says seven hours also is linked with other health benefits, such as less risk of heart trouble and diabetes.

The study in The Journal of the American Geriatrics Society was supported by the National Institutes of Health.
