AI tells user to submerge heatstroke victim in ice water only up to waist, but full immersion to neck (excluding head) is the gold standard for exertional heatstroke

Root Cause
AI incorrectly recommends partial immersion, likely from confusion with cold-water immersion safety protocols; the evidence-based treatment for exertional heatstroke (core temp >40°C / 104°F) is immediate cold-water immersion up to the neck (head out) in water at 1-15°C (35-59°F), which reduces core temperature at ~0.35°C/min, the fastest known method.

Dead Ends
Common approaches that don't work:
-
Submerge victim only up to the waist to avoid shock or aspiration
90% fail
Partial immersion slows cooling dramatically; only ~0.1°C/min compared to 0.35°C/min for full immersion, increasing risk of organ damage and death.
-
Use ice packs on armpits, groin, and neck instead of immersion
85% fail
Ice packs have limited surface area and cool at ~0.1°C/min; they are inferior to cold-water immersion and may delay definitive treatment.
-
Pour cold water over the victim's head first to cool the brain
75% fail
The head has high blood flow but cooling the head alone is ineffective; whole-body immersion is required. Pouring water over head may cause aspiration.
