Wash your hands

Yes, you've heard it before, but it really does work. Regular soap and warm water will kill germs—just make sure to rub you hands vigorously for 15 to 20 seconds. And don't stop washing them even if you're already sick. "By washing your hands regularly, you decrease the spread of disease," says Dr. Thomas Weida, professor of family and community medicine at Penn State University's Hershey Medical Center.
