We're all experts on hand-washing now: Hot water and soap for at least 20 seconds. But a lot of people don't know that DRYING your hands is an important step too.
When your hands are wet or even damp they actually pick up more germs than when they're totally dry. So if you touch something like a doorknob with your damp hands, you're more likely to get sick.
Studies have found that drying off with a towel also removes more germs than just washing alone does. Now, the one thing you don't want to use in public bathrooms are the hand dryers.
Experts say to use paper towels in public bathrooms if they're available, and carry a tissues in your pocket in case they're not.
Another way to avoid germs is by avoid touching the door handle. You should use a paper towel to open it. Just prop it open with your foot, so you can throw it away.
