Mehmet Oz, MD, Cardiology, answeredIf cold and flu season has ended, you might think it's not as important to wash your hands regularly. Watch this video by Dr. Oz to find out why washing hands is never out of season.
Stacy Wiegman, PharmD, Pharmacy, answeredFrequent hand washing helps to protect you and others from the germs that cause colds and the flu (influenza). These germs can be passed from one person to another through hugs, hand shaking and other personal contact. They also live on objects you touch every day, such as door knobs, telephones and keyboards. Once a cold or flu germ is on your skin, you can become infected. Washing your hands with warm water and soap can help prevent you from infecting yourself with cold and flu germs or spreading them to others.

Soap and water can remove bacteria from your hands and keep it from reaching your eyes, nose and mouth—and from infecting you. A University of Colorado study showed that students who washed their hands more often experienced fewer incidences of the common cold and flu.
