Ban Colds With Clean Hands

Every winter, your house becomes “command central” for the war against colds. Washing your hands frequently is one of the best things you can do to prevent colds, say public-health experts. Be sure to soap up after using the bathroom, changing a diaper, and blowing your nose.

But what if a sink isn’t available?

You may be able to build your family’s defenses by adding a waterless, alcohol-based hand gel to your weaponry, according to a recent study. Put a teaspoon-sized dab of gel in your hands and rub them until they are dry.
