1.) Being cold will make you sick. FALSE! Going outside without a coat will not make you sick - it will just make you shiver. You have to be exposed to a virus to come down with a cold or the flu.
2.) Using an old toothbrush will make you sick. FALSE again! It is fine to use the same toothbrush you used while you were sick after you recover. Your body becomes immune to the specific virus that made you sick. Using someone else's toothbrush...that's a whole different story.
3.) Hotel rooms have germs. TRUE! According to research from University of Virginia School of Medicine, 1/3 of hotel room surfaces still had germs for almost an entire day after a sick person stayed overnight. Something to keep in mind if you're traveling during cold and flu season.
4.) Kissing your sick boyfriend/girlfriend will make you sick. FALSE (somewhat)! Thank goodness, right, especially with Valentine's Day around the corner. Studies show that viral infections enter the body through the nose and eyes. It is safer to kiss someone who is sick rather than shake his/her hand. You are likely to take that hand (now infected with the virus) and rub you eyes or nose.
