How do i GET fever?

Fevers are caused by your body increasing your body temperature in order to kill a germ or virus that you have picked up. The higher your body temperature, the less ability the virus/germ has to replicate itself so the germ begins to die off. Tylenol or ibuprofen are appropriate fever control measures as is drinking cool/cold liquids. There is nothing in iodine that will lower your temperature and you should not be using this substance for anything. Hot water will increase your skin temperature for only a few minutes. Illness is the only way to "get" a fever.
