Why is Handwashing So Important?

It’s especially important in the midst of cold and flu season to do all you can to prevent the spread of germs, and proper handwashing habits go a long way to keeping you, your family, friends, and coworkers healthy.


How Do Germs Spread?

Because people often touch their mouth, eyes, and nose, germs have numerous opportunities to enter their body and, potentially, make them sick. Germs can multiply under certain conditions and in certain types of food and drink. Therefore, it’s important to ensure that your unwashed hands aren’t the source of these germs. When individuals with unwashed hands touch commonly used surfaces, such as counters, handrails, door handles, etc., the germs they leave behind can be transferred onto other people’s hands. Additionally, germs expelled when someone coughs or sneezes can also cause the spread of disease. It’s important to do your best to keep your hands as clean as possible—for your health and for the health of others.


How Does Soap Remove Germs?

It’s important to create a good lather with soap and water and scrub your hands for at least 20 seconds. When you do, the soap molecules surround and trap the oil, dirt, and germs on your skin and form structures called micelles. The trapped oil, dirt, and germs become suspended in the soapy water and are washed away when you rinse your hands. If you wash for a shorter amount of time, you will remove less germs according to the CDC.


What is the Proper Technique for Washing Your Hands?

  1. Wet your hands. You are able to create a more effective lather if you get your hands wet before adding the soap.
  2. Work the soap and water into a good lather.
  3. Scrub your hands for at least 20 seconds. Ensure to wash the palms and backs of your hands, under your fingernails, and between your fingers.
  4. Rinse your hands and dry them thoroughly.
  5. When using a public washroom: To keep your hands clean, turn off the taps and open the door with a paper towel.

Is Hand Sanitizer a Substitute for Soap and Water?

While washing your hands with soap and water is a more effective way of removing germs from your hands, it isn’t always possible or practical to do so. A hand sanitizer that contains at least 60% alcohol will kill certain types of germs and thus, reduce the possibility of becoming sick.

What is the Proper Way to Use Hand Sanitizer?

  1. Use an adequate amount of hand sanitizer to cover your hands.
  2. Rub it in to the palms, the back of your hands, and between your fingers.
  3. Rub your hands together until the hand sanitizer is absorbed and your hands feel dry, for approximately 20 seconds.
  4. Do not dry your hands with paper towel, as this will decrease the sanitizer’s effectiveness

What is the Difference Between Using Hand Sanitizer and Washing with Soap and Water? Soap and water remove all types of germs. Hand sanitizer kills certain germs on your skin. Although alcohol-based hand sanitizers can quickly reduce the number of germs in many situations, soap and water are more effective at removing certain kinds of germs, including harmful chemicals.
