From the press release:
About 10 percent of adults report not getting enough rest or sleep every day in the past month, according to a new four-state study released by the Centers for Disease Control and Prevention′s (CDC) Morbidity and Mortality Weekly Report.
The data from the four states-Delaware, Hawaii, New York, and Rhode Island-may not reflect national trends. But an additional study conducted by CDC utilizing data from the National Health Interview Study indicated that across all age groups the percentage of adults who, on average, report sleeping six hours or less has increased from 1985 to 2006.
Nationwide, an estimated 50 to 70 million people suffer from chronic sleep loss and sleep disorders. Sleep loss is associated with health problems, including obesity, depression, and certain risk behaviors, including cigarette smoking, physical inactivity, and heavy drinking.
