How does the body raise its temperature during a fever? I know why it does, but I want to know how.

The other answer is crazy, you get a fever because your white blood cells have to travel really quickly to the area they are needed in the body and that increases the speed of your blood flow as a whole. All of that extra movement causes your body to heat up more than it normally would.

Cool. I always knew why a fever was caused, I just never knew how the body heated itself up during one. Also, why do you feel cold during a fever?

I'm sorry, when I started writing that the only other comment was "I think it boils you inside???"
That being said, you should have clarified what you meant by immune system because white blood cells aren't the only part of the immune system and they make up only a small percentage of blood.

your immune system is working so hard and it uses so much energy that the only way for you to use all of the excess is to heat up... I think
