Environmental emergencies can sneak up fast, and once the body starts losing its ability to regulate temperature, things can go downhill in a hurry. In this episode, we break down hot and cold emergencies, focusing on how the body responds to temperature extremes, what warning signs EMTs should watch for, and when simple exposure becomes a true medical emergency.

Mike, Max, and Jonathan walk through active versus passive warming and cooling, the physiology behind hypothermia and hyperthermia, and how heat loss, dehydration, exposure, and poor decision-making can all stack together in the field. From frostbite and local cold injuries to heat exhaustion and heat stroke, this episode is all about recognizing problems early and treating temperature emergencies before they spiral.
