New research shows that a good night’s sleep may be one of the best defenses against the common cold. A team from Carnegie Mellon University in Pittsburgh tested a group of healthy volunteers, by locking them in a hotel for five days after infecting them with a cold virus.
The researchers found those who slept less than seven hours a night were three times more likely to catch a cold than their more well-rested colleagues. And it’s not just the amount of sleep that matters. Quality counts. Volunteers who spent their time in bed tossing and turning instead of snoozing were also much more likely to develop sneezing, sore throat and other cold symptoms.
The study supports the theory that sleep is important to immune function, and it’s the first evidence that even relatively minor sleep disturbances can influence the body’s reaction to cold viruses.
The bottom line: here’s another reason why you should make time in your schedule to get a complete night of rest.
