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, PA, 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," say the author of the study. It provides another good reason why people should make time in their schedules to get a complete night of rest.
