It seems like the best idea would be to warm them up as quickly as possible, but I’ve heard that’s not the right course of action. Why should you warm them up slowly? And what happens if they warm up too quickly? I’m from the Southeastern US, so I have no experience with extreme cold or frostbite, I’m merely curious

Because the amount of oxygen (blood flow) a cell needs is directly proportional to how warm it is. When you warm someone up by putting them in warm water or in front of a fire you warm them up from the outside in. Their body’s core temperature is still low so their blood vessels in their extremities will still be constricted even if you warm their hands up. Their hands are warm and need blood flow but their core is still cold and wants to conserve heat so it will still reduce blood flow to the hands which will result in more cell damage.
