(BOSTON) -- Nearly a quarter of all American workers -- 23.2 percent -- suffer from insomnia, according to a new study, and that is costing the country $63.2 billion a year.
The study, published in the Sept. 1 issued of Sleep and led by Ronald Kessler, a psychiatric epidemiologist and professor of health care policy at Harvard Medical School, found that the lack of sleep is causing workers to lose 11.3 days of productivity annually. Financially, that amounts to $2,280 per year.
As Kessler explains, “It’s an underappreciated problem. Americans are not missing work because of insomnia. They are still going to their jobs but accomplishing less because they’re tired. In an information-based economy, it’s difficult to find a condition that has a greater effect on productivity.”
Researchers used a national sampling of 7,428 employees, which was part of the larger American Insomnia Study, to determine these results.
The study also found that insomnia affected only 14.3 percent of workers aged 65 and older, and that female employees were more prone to it than their male counterparts -- 27.1 percent to 19.7 percent, respectively.
