QuickStats: Percentage of Adults Aged >18 Years* Who Reported
an Average of <6 Hours of
Sleep† per 24-Hour Period, by Sex and Age
Group --- National Health Interview Survey, United States, 1985 and
2006§
* N = 23,679 (10,457 men and 13,222 women).
† Based on response to the following question: "On average, how many hours of sleep do you get in a 24-hour
period?" Respondents could indicate getting 1 to 24 hours of sleep.
§ Estimates were based on household interviews of a sample of the noninstitutionalized, U.S. civilian population.
From 1985 to 2006, the percentage of men and women who reported an average of
<6 hours of sleep per 24-hour period increased in all age groups. In 2006, for both men and women, the percentage
of respondents reporting <6 hours of sleep per 24-hour period was highest among those aged 30--44
years and 45--64 years. The National Sleep Foundation recommends 7--9 hours of sleep per 24-hour period
for adults (additional information available at
