Short Sleeping Equals More Colds

Your mother may have told you that if you don't get enough sleep you will get a cold. Now researchers have found that sleeping less than 6 hours per night does increase your risk of developing a cold when exposed to rhinovirus (the virus responsible for most colds). After adjusting for confounders, those who slept less than 6 hours had 4 times greater risk than those who slept more than 7 hours.
