Myth #3: Hands That Aren't Soiled Don't Need Washing

Billions of micro-organisms can be present on your skin at any one time and you still won't be able to see them. Therefore, without conscious effort, it's relatively easy to forget to clean your hands before a meal, after blowing your nose, or after going to the washroom.

Proper handwashing is one of the most basic ways to stay healthy. It prevents the transmission of bacteria and viruses from the environment to your body, or when you are sick, from you to other people. However, a quick 5-second rinse is not enough. If done correctly, handwashing should take at least 10-15 seconds to complete.

At the minimum, you should use running water, an antibacterial soap, and a meticulous technique that ensures all skin surfaces are cleaned--from underneath your fingernails to the spaces between your fingers. When you're done, grab a paper towel and use this to turn off the faucet.

All this might seem unnecessary and cumbersome at first but will be quite easy to do once you get into the habit. As a reward for your efforts, you'll be keeping yourself and your family protected from a hundred different diseases.

So remember to wash your hands several times a day. The benefits far outweigh the costs. Stay tuned.
