ot sleeping enough can have serious health costs. But it can have pretty big financial costs, too, according to a new study in the journal Sleep. Insomnia is "an under-appreciated problem," says lead author Ronald Kessler, at Harvard Medical School. "Americans are not missing work because of insomnia," but they are doing lousy work because they're tired. "It's difficult to find a condition that has a greater effect on productivity." How great is the hit to our economy, and our lives? Here, the numbers:
Days the average worker loses to insomnia each year
Estimated cost of that insomnia, in lost productivity, per worker
Estimated number of American employees who report being impaired during the day due to poor sleep
Cost of that lost productivity for the nation as a whole
Percentage of U.S. workers sleep-deprived due to insomnia
Percentage of workers 65 and older with insomnia
Percentage of working men with insomnia
Percentage of working women with insomnia
Percentage of insomnia among workers with a high school education
Percentage of insomnia among workers who dropped out of high school
Percentage of insomnia among workers with a college degree
Percentage of insomniacs on medication or in behavioral therapy
Annual cost of sleep-aid medication
Annual cost of sleep behavior modification therapy
Amount Americans spend on coffee each year
Number of full-time employees surveyed for the study
