Lack of sleep = get sick
Really? - The Claim - Lack of Sleep Increases the Risk of Catching a Cold. - Question - NYTimes.com
Studies have demonstrated that poor sleep and susceptibility to colds go hand in hand, and scientists think it could be a reflection of the role sleep plays in maintaining the body’s defenses.
In a recent study for The Archives of Internal Medicine, scientists followed 153 men and women for two weeks, keeping track of their quality and duration of sleep. Then, during a five-day period, they quarantined the subjects and exposed them to cold viruses. Those who slept an average of fewer than seven hours a night, it turned out, were three times as likely to get sick as those who averaged at least eight hours.
Sleep and immunity, it seems, are tightly linked.
