When Should I Wash My Hands?

It’s never a bad time to wash your hands, but it’s especially important before or after you do certain things:

  • After coughing, sneezing, or blowing your nose
  • After touching common surfaces such as tables, countertops, and doorknobs
  • While taking care of someone who is sick
  • After going to the bathroom
  • Before, during, and after making food
  • Before eating
  • Before and after treating a cut
  • After changing diapers or cleaning up a child who went to the bathroom
  • After touching an animal, animal waste, or animal food
  • After touching garbage

How Should I Wash My Hands?

The Centers for Disease Control and Prevention recommends washing your hands with soap and water for at least 20 seconds.

If soap and water are unavailable, you can use hand sanitizer. The CDC says the hand sanitizer you use should contain at least 60 percent alcohol.

To properly wash your hands:

  • Wet your hands with clean running water. The water can be warm or cold.
  • Apply soap to your hands and rub them together to lather the soap. You also should lather the back of your hands, between your fingers, and underneath your nails.
  • Rub your hands for at least 20 seconds.
  • Rinse your hands under clean water.
  • Use a clean towel to dry your hands, or air dry them.

To use hand sanitizer, apply the gel to one of your palms and rub your hands together. Rub the gel all over your hands and fingers for at least 20 seconds, until your hands are dry.

If you want to make sure you wash your hands for 20 seconds, you can sing the “ABCs” or “Happy Birthday” twice.

UPMC takes steps to ensure its facilities are clean and sanitary for patients and visitors. Washing your hands according to the steps above may help prevent you from getting sick.
