Sleep Boosts Seniors' Brain Power: Study

Getting a good night's sleep may be as important as diet, exercise, and keeping mentally active when it comes to staying sharp as we age. A new University of Oregon-led study has found people who get six to nine hours of sleep a night tend to think better than those sleeping fewer or more hours.

The research, which tracked more than 30,000 people 50 and older in six nations, found that individuals who routinely get too little — or too much — sleep tend to score poorly on measures of cognitive abilities than those getting the recommended levels of shut-eye.
 
"We wanted to look at aging, particularly dementia and cognitive decline as people get older, and the importance of sleep. Our results provide compelling evidence that sleep matters a lot," said Theresa E. Gildner, who led the study, published in the Journal of Clinical Sleep Medicine.

"In all six countries, which are very different culturally, economically and environmentally — despite all these differences — you see similar patterns emerging."
 
Study participants in the six nations — China, Ghana, India, Mexico, the Russian Federation, and South Africa — were asked about the number of hours they typically sleep. They then went through five standard cognitive tests involving immediate recall of a list of presented words, delayed recall of those words later, forward and backward recall of long lists of numbers, and a verbal fluency test in which they listed as many animals as possible without repetition.
 
The results showed:
  • Men reported higher sleep quality than women in all six nations, with men and women in Mexico reporting the highest.
  • Women reported longer sleep durations than men in all countries except Russia and Mexico. Men and women in South Africa slept longer than in any other country. The least sleep hours for both sexes occurred in India.
  • Individuals sleeping less than six hours and more than nine hours had significantly lower cognitive scores compared to those in the intermediate group.
"This study is hugely powerful and so different from what's been done in the past, simply because of the consistency of how the data was collected -- multi-national, random samples of people," said J. Josh Snodgrass, professor of anthropology at the UO. "Sleep is something that is important but often undervalued in our society."
 
The study was funded, in part, by the National Institutes of Health.
