ELI5- Why do our bodies perceive ambient temperatures with pain? Like the cold hurts

406 viewsChemistryOther

So I want to understand why exactly our bodies say the outside cold hurts and why the hot temperatures feel nice up to an extent then it hurts but also just feels more uncomfortable. I understand the direct touch aspect but not ambient.
So I understand the evolutionary need for it but I want to know the science. What is going on in your body that makes the cold hurt

My guess, based purely on my own experiences, is that the cold ambient temperature makes it feel like my muscles are contracting, borderline cramping which sends pain signals to the brain. In contrast, warmth usually helps muscles relax and loosen up which might explain why you feel less pain in warmer ambient temperatures. That’s how I’ve rationalized it based solely on “ice to reduce swelling and heat to relax” from my experiences with years of PT.
