The National Sleep Foundation has released its annual "Sleep in America Poll," which reveals how much sleep Americans are getting, what their bedtime habits are, and who's taking medications when sleep is elusive.
This year, for the first time, the report explored differences in the sleep habits of different ethnic groups.
And overall, no one's getting enough sleep. Fewer than half of respondents from each ethnic group say they get a good night's sleep on most nights.
African Americans reported the least amount of sleep. Inadequate sleep is starting to be associated with obesity, heart disease and diabetes -- all diseases that are more prevalent among African Americans.
