The poll also shows sleep is never completely peaceful for 8 percent of adults, while the remainder lose at least one night a week, according to results released today by the International Longevity Center-USA, a New York-based non-profit policy group.
Thirty-eight percent of men sleep well every night, compared with 27 percent of women. However, only half of adults are getting the recommended eight hours of sleep per night.
The other half blame long working hours, stress, and ill-health as a reasons why they fail to rest well at night.
While over 70 percent of adults admit they suffer from some form of sleep disorder, only 40 percent have been treated by a doctor.
"We've concluded that maybe sleep should be another one of the vital signs that doctors should check,'' says Robert Butler, a doctor and chief executive of the Longevity Center.
The random telephone survey of 1,003 adults, age 50 or older, was conducted by the Gallup Organization.
The results have been statistically adjusted to be nationally representative of this age group. The margin of error was plus or minus 3 percentage points.
