“Wash your hands!” How many times have you heard that from your parents? You might think they’re just nagging(唠叨) you, but actually the most important thing you can do to keep from getting sick is to wash your hands.
If you don’t wash your hands well and often, you can pick up germs(细菌) and then infect yourself. You’re at risk every time you touch your eyes, nose, or mouth. In fact, one of the most common ways people catch colds is by touching their nose or their eyes after the cold virus has gotten on their hands.
If people don’t wash their hands often (especially when they’re sick), they can spread germs directly to other people. And before they know it, everyone around them is infecting something!
The American Society for Microbiology and the American Cleaning Institute did a survey of hand washing. They asked people questions about their hand-washing habits and also watched people in public restrooms. Here are the results.

•Only 42% of the people in the survey wash up after petting a dog or cat.

•Use warm water (not cold or hot).
•Use whatever soap you like. Antibacterial (抗菌性的) soaps are popular but regular soap works fine.
•Rub(摩擦) your hands together well and wash all surfaces, both sides of your hands, your wrists, between your fingers, and around your nails. Wash for 20 seconds.
•Rinse(冲洗) well under warm running water and pat dry with a clean towel.
