Less Sleep, More Colds

Less Sleep, More Colds

“People who sleep fewer than seven hours a night are nearly three times as likely to get a cold than people who average eight or more hours of sleep,” says a report from Carnegie Mellon University, Pittsburgh, Pennsylvania, U.S.A. And those who stay awake “as little as 8 percent of the time they [are lying] in bed [are] five-and-a-half times more likely” to catch a cold than those who sleep more soundly. “Although sleep’s relationship with the immune system is well-documented, this is the first evidence that even relatively minor sleep disturbances can influence the body’s reaction to cold viruses,” said Sheldon Cohen, the study’s lead author. “It provides yet another reason why people should make time in their schedules to get a complete night of rest.”
