Live Long, Sleep Better?
Some 100 million Americans who suffer from sleep disorders may well have something to look forward to in old age: a good night’s sleep.
In a study of more that 150,000 Americans, researchers discovered that sleep seems to improve over a lifetime, with the fewest sleep complaints coming from people in their 80s.
“This flies in the face of popular belief,” said Michael Grandner, Ph.D., 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 appears in the March edition of the journal Sleep.
Researchers performed a random telephone survey of 155,877 adults and then examined the reported rates of sleep disturbance and daytime fatigue.
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.
Surprisingly, with the exception of an increase 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.”
Grandner said the study’s original intent was to confirm that increased sleep problems are associated with aging, using the largest and most representative sample ever to address this issue.
Instead, the results challenge the conventional wisdom that difficulty sleeping is perceived more by older adults, and challenge the general clinical practice of ignoring sleep complaints from older adults as a normal part of aging.
