About a third of American adults are getting less than seven hours of sleep a night, according to two studies from the Centers for Disease Control and Prevention, a habit that could put them at risk for serious health problems.
In a survey across 12 states, about 35 percent of adults said they slept for less than seven hours a night. Lack of sleep can impede on personal safety, as researchers said almost 38 percent of respondents said they had intentionally fallen asleep due to fatigue, while 7 percent said they had been tired enough to fall asleep while driving. Furthermore, almost 5 percent said they had fallen asleep while behind the wheel at least once in the previous 30 days.
Performing daily routine tasks may be up to 50 percent more difficult for adults who sleep for less than seven hours compared to those who get more shut-eye, according to researchers. In a study examined the connection between hours of sleep and routine, scientists found that 28.2 percent of those who did not get enough sleep reported having trouble concentrating on a task and 18 percent had difficulty remembering things.
Consistently going without sleep can also cause a multitude of physical ailments, possibly racking up life insurance costs. The Washington Post reports that sleeping less than seven hours a night has been linked with an increase in obesity, heart disease, cancer and diabetes.
