: 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

The body can do that – we have brown adipose tissue meant specifically for that. The problem is, it doesn’t really work well in modern people, because we rarely get exposed to cold temperatures anymore.

Essentially, what Wim Hof does is comepletely normal, and more or less anybody should be able to do it with some regular cold exposure and enough food to eat.
