Defying Expectations: Penn Medicine Study Reveals Americans Report Improved Sleep with Age

PHILADELPHIA — Aging does not appear to be a factor in poor sleep, a new study by Perelman School of Medicine at the University of Pennsylvania shows. In fact, subjective sleep quality seems to improve over a lifetime, with the fewest complaints coming from people in their 80s. The new study is published in the journal SLEEP.

“This flies in the face of popular belief,” said Michael Grandner, PhD, research associate at the Center for Sleep and Circadian Neurobiology and lead author of the study. “These results force us to re-think what we know about sleep in older people — men and women.”

The study examined rates of sleep disturbance and daytime fatigue reported by 155,877 adults participating in a randomized national telephone survey. Respondents were asked about sleep disturbances and daytime tiredness. The survey also asked about race, income, education, depressed mood, general health and time of last medical checkup. All responses were weighted so that they matched U.S. Census data.

Health problems and depression were associated with poor sleep, and women reported more sleep disturbances and tiredness than men. But except for an uptick in sleep problems during middle age — more pronounced in women than men — sleep quality improved consistently over a lifetime. Or at least that’s how people reported their sleep.

“Even if sleep among older Americans is actually worse than in younger adults, feelings about it still improve with age,” said Grandner. “Once you factor out things like illness and depression, older people should be reporting better sleep. If they’re not, they need to talk to their doctor. They shouldn’t just ignore it.”
