Fevers are Good for you
Fever is a defense that the body uses to kill viruses and other germs. We
know that germs growing in cultures die if you turn up the temperature too
much. The same is happening in your body when your brain turns up the temperature when you get sick. We also know that the white blood cells and other protective mechanisms in the body work more efficiently at
higher temperatures. Getting a fever is an important part of your body's defense against infection.
