The number of employed Americans reporting fewer than six hours of sleep a night has increased in the last 10 years, new CDC data shows.
Researchers analyzed data from the National Health Interview Survey for the years 2008-09 and 2017-18.
They found the percentage of employed adults who reported sleeping an average of six hours or less in a 24-hour period increased from 28.4 percent during 2008-09 to 32.6 percent during 2017-18.
The biggest increase was recorded among the self-employed, with 24.3 percent reported sleeping six hours or less in a 24-hour period during 2008-09, and 31.4 percent reporting the same during 2017-18.
