By now, you’ve seen a lot of information about the need to wash your hands to help prevent or slow the spread of the coronavirus and COVID-19. So, let’s test your knowledge about the best way to clean your hands:

  1. It doesn’t matter how long I wash my hands as long as I use soap – FALSE
    The next time you’re in the restroom and washing your hands, think of the chorus of your favorite song. Studies show that you should scrub your hands with soap for a minimum of 15-30 seconds in order to effectively remove germs.
  2. Hand sanitizers can replace washing your hands with soap and water – FALSE
    Washing hands with soap and water is the best and most effective way to reduce the number of microbes and germs on hands. Although alcohol-based (at least 60%) hand sanitizers can quickly reduce the number of germs on hands in some situations, they are not as effective as soap and water when it comes to removing and inactivating dangerous gastrointestinal illness-causing germs.
  3. The hotter the water you use for handwashing, the better – FALSE
    Studies show that water temperature does not affect germ removal. In fact, there is no research to prove that higher temperatures improve handwashing at all. Hotter water can also dry out skin, which leaves your skin more susceptible to germs and can make handwashing painful. It is best to wash your hands with the temperature that you find comfortable.
  4. You don’t have to dry your hands after washing them – FALSE
    Studies show that germs can be more easily transferred to and from wet hands, which is why drying hands is essential to staving off bacteria after handwashing.
  5. Hand dryers are more hygienic than paper towels – FALSE
    Researchers found that paper towels are superior to air dryers and can help remove bacteria, unlike air dryers, which can increase bacteria counts. Because air dryers have been shown to spread bacteria between 3 and 6 feet from the device, paper towels are also far less likely to contaminate other restroom users.
