32. Health Myth: You have to wash your hands in hot water.
While washing your hands in warm or hot water may be more comfortable for you, it is unnecessary. You can 100% wash your hands in cold water and have the same effect as hot water. So if you only have cold water, do not worry! The important part of hand washing is that you are using both soap and water. Water alone will not kill germs, as it needs to be so hot to kill germs that it will burn you badly. You just need to lather the soap to get rid of dirt, and using an antibacterial soap will kill any bacteria for you.
While you don’t need to worry about the temperature, you need to know precisely how to wash your hands. It seems like a straightforward concept when you say it. However, many people are washing their hands incorrectly. To clean your hands, you need to wet your hands thoroughly, lather with soap getting all surfaces(palms, back of hands, in between fingers, and under nails), then rinse thoroughly, dry your hands and use the paper towel to turn off the tap. It is important to lather for the right amount of time, 20-30 seconds. Sing “Happy Birthday” twice in your head, and you should be good.
