Avoid Colds and Flu With Expert Hand-Washing Advice


Can you really avoid colds and flu this season with simple hand-washing?  Amy McCombs, Renown’s director of Infection Prevention, joins Channel 4 KRNV (NBC) and Channel 11 KRXI (FOX) for Best Medicine Wednesday — a new weekly segment highlighting useful health information — and shares how to stay healthy this season with this very simple practice.

Shaking hands, turning doorknobs, drafting emails — all seemingly innocuous activities of everyday life. But whenever you touch another person, or touch an object another person has touched, you’re collecting their germs on your hands. Touching your own mouth, eyes or nose exposes you to whatever germs you’ve collected.

That makes hand-washing the most important step you can take to prevent illness. And while that may seem like an elementary — if not silly — reminder, studies have found that a staggering 85 percent of people do not practice proper hand hygiene.

We asked Amy McCombs, Renown’s director of Infection Prevention, to give us some hand-washing tips for a safer, healthier cold and flu season.

Is there a wrong way to wash your hands, or is it more about making sure you do it the right way?

Honestly, it’s a little bit of both. There is a wrong way since 85 percent of us don’t wash correctly. This could be for a variety of reasons. It could be because you don’t wash long enough, don’t get in between your fingers, don’t clean your palms or don’t clean the tops of your hands.

If so many people wash their hands incorrectly, what are the steps to do it correctly?

The big thing to remember is to wash for at least 20 seconds with soap and water. A good rule to make sure you’re washing long enough is to sing “Happy Birthday” twice through.

It’s also important to get a nice lather of soap and make sure you wash between your finger, both the tops and palms of your hands and your nail beds. And if you wear jewelry, you need to remove it or make sure you get lather and friction underneath.

Then rinse completely and dry.

How frequently should we wash our hands? Are there certain times where it is more important than others?

As most of us are taught as kids, you need to wash your hands before you eat or prepare foods, after you touch raw produce and meat and after you use the restroom.

You should also wash your hands after sneezing or coughing, touching your eyes, nose and mouth or coming in contact with someone who is sick.

Do you recommend hand-washing over hand sanitizer?

Ideally, you should wash your hands instead of using hand sanitizer, but if sanitizer is all you have, then use it.

Alcohol-based hand sanitizers are best. Use about a nickel or quarter size and vigorously rub the tops of your hands, palms and in between your fingers until the sanitizer is completely dry.

Remember that if your hands are physically dirty, or if you’ve come in contact with bodily fluids, you should thoroughly wash your hands with soap and water instead of hand sanitizer.

Does washing your hands really prevent illnesses like the cold and flu?

Definitely. The CDC recommends hand-washing as one of the best ways to avoid getting sick and spreading illness. Hand-washing has been shown to reduce the number of people who get colds and respiratory illnesses by 21 percent.
