Sleep it Off The coughs, the colds, the general dreariness: Winter is the kind of season that makes sleep look appealing all day long. And according to a recent study at Carnegie Mellon University, Pittsburgh, it might be the perfect remedy for those winter blues. Research found that individuals who get less than seven hours of sleep a night are three times as likely to develop respiratory illness following exposure to a cold virus than those who get eight hours or more of sleep a night. In the study, which included 153 healthy men and women, individuals who slept less were more likely to develop a cold. Lower sleep efficiency was also associated with catching a cold. Those who slept 92 percent of the time in bed were five and a half times more likely to become ill than those whose efficiency was 98 percent or more. |
