: 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

Your body temperature is largely regulated automatically. For the body ‘feeling cold’ isn’t reason enough to heat up intensely since its not a survival risk (typically), people can feel cold for way longer than they think.

All else being equal, having a healthy strong immune system via (semi-) regular exercise, consistent sleep, and eating more fruits in your diet will boost your average energy levels and negate some of the cold you feel, although the cold will be there you will feel it less.
