Reader Question: My mom told me that if I don't get enough sleep I'll catch a cold. Is she right?
Listen to your mom. Colds are caused by viruses, which means you can't actually "catch" one from lack of sleep. But not getting enough shuteye will definitely make you more likely to get sick when you're exposed to a cold virus. In fact, a new study in the Archives of Internal Medicine found that people who got less than seven hours of sleep each night were almost three times more likely to develop a cold than those who got eight or more hours.
To avoid viruses, wash your hands often and thoroughly, and keep your hands away from your mouth and nose. You can also boost your immune system by getting regular exercise, eating a healthy diet and, as your mom says, getting enough sleep.
I want to hear from you, so e-mail me your questions at.
