Older adults cope with sleep deprivation better than young adults, U.S. researchers said. The older adults -- ages 59-82 years -- showed more resiliency to total sleep deprivation than young adults -- ages 19-38 years -- on a range of measures of cognitive performance, including working memory, selective attention/inhibition, and verbal encoding and retrieval. Performance of young adults significantly declined on all three tasks during total sleep deprivation while that of older adults did...

Older women who reported taking daily naps had a significantly greater risk of dying, U.S. researchers said. The study, published in the Journal of the American Geriatrics Society, said the results are in contrast to a number of prior studies which have indicated that daily napping improves health.
