Medically reviewed by: Yamini Durani, MD

Why Is Hand Washing So Important?

Hand washing has always been the best way to keep from getting sick. But with the coronavirus (COVID-19) outbreaks, hand washing matters more than ever.

Coronavirus spreads easily. Hand washing prevents the spread of germs, including coronavirus.

When you wash your hands, you protect yourself from germs. You also protect people in your family. And with the coronavirus, when you stop the spread of germs at home, you protect people in the community too.

What's the Best Way to Wash Hands?

Here's how to scrub those germs away:

  1. Wet your hands with clean, running water (warm or cold). Make sure the water isn't too hot.
  2. Use soap. Lather up for about 20 seconds. Any soap works. It doesn't have to be antibacterial.
  3. Make sure you wash between your fingers, on the backs of your hands, and under your nails where germs like to hang out. Don't forget your wrists!
  4. Rinse and dry well with a clean towel.

When Should I Wash My Hands?

Make a habit of regular hand washing. It's most important:

  • before eating and cooking
  • after using the bathroom
  • after cleaning around the house
  • after touching pets and other animals
  • before and after visiting or taking care of sick people
  • after blowing your nose, coughing, or sneezing
  • after being outside
  • after handling mail or packages

What if you don't have soap and water? Waterless hand sanitizers or scrubs are good too. They come as liquids, wipes, sprays, or towelettes. You can buy travel sizes to keep in your book bag, car, locker, purse, or sports bag.

How Do Clean Hands Help Health?

Good hand washing is the first line of defense against the spread of illnesses, including coronavirus (COVID-19). And it helps protect you against everything from the common cold to more serious infections, such as meningitis, bronchiolitis, the flu, hepatitis A, and many types of diarrhea.

How Do Germs Spread?

Germs spread in lots of ways. For example:

  • touching dirty hands
  • changing dirty diapers
  • through contaminated water and food
  • through droplets in the air released during a cough or sneeze
  • on contaminated surfaces
  • through contact with a sick person's body fluids

When you come into contact with germs, you can become infected just by touching your eyes, nose, or mouth.

Seize the power of hand washing! It's one of the best things you can do to help yourself and others.
