Heat-related emergencies are increasingly common and extend far beyond wilderness treks. Patients collapse at athletic events, construction sites, firegrounds, disaster shelters, rural farms, and city sidewalks when heat overwhelms human physiology. This session reviews the recognition and management of heat illness, from mild exhaustion to life-threatening heat stroke, in both resource-rich and resource-limited contexts. Case-driven teaching and evidence-based cooling strategies will equip participants with the skills to intervene effectively, decide when rapid evacuation is essential, and prevent further morbidity. Attendees will leave with actionable tools to manage heat illness wherever it strikes — whether in a crowded stadium, a sweltering fire scene, or a remote hiking trail.
