: When you get cold what stops our body from just heating itself up like when we are sick?

Question

I know people can get fevers up to +100f/37c. So why can’t our body just flip a switch and turn on a fever essentially. I have plenty of “stored” energy so I don’t see how that would be a problem.

Answer 1

It tries to heat you up but you lose heat too fast and your body can’t compensate.

When you are sick, even at your room temperature you can feel cold. Your body conserves more energy to increase your body temperature. If it is too cold your body temperature still can’t go up.
