Chilling Out with Colds
You wake up in a cranky mood. Your head hurts. You don't have the energy to even get out of bed. And you can't breathe out of your nose. What's wrong? You have a cold!
Having a cold is the #1 reason kids visit the doctor and stay home from school. Kids get up to eight colds per year with each cold lasting an average of 5 to 7 days. Let's find out more about them.
What Is a Cold?
A cold is an infection of the upper respiratory system. This just means it affects the nose, throat, and ears. A cold virus gets inside your body and makes you sick. The rhinovirus (say: rye-no-vye-rus) is the most common cold virus, but more than 200 viruses can cause colds. Because there are so many, there isn't a vaccination, or shot, to prevent you from getting colds.
Fortunately, your body already has the best cold cure — your immune system. The immune system defends your body against illness. White blood cells are the immune system's main warriors. They're your own private army working to help you feel better. Take that, cold viruses!
