In heat stroke treatment, which method constitutes rapid cooling?

• A. Cold water immersion only
• B. Rapid cooling via evaporative methods or immersion; remove excess clothing; hydration
• C. Rest and hydration only
• D. Ice packs only

Answer: (B)

Rapid cooling is the priority in heat stroke treatment because lowering the core temperature quickly limits organ and brain damage. The best approach combines fast cooling methods—immersion in cold water or evaporative cooling (spraying cool water while fanning)—to maximize heat transfer from the body. Removing excess clothing helps heat escape more efficiently, and hydration supports circulation and fluid balance after sweat loss. Together, these steps achieve the quickest decrease in core temperature. Rest and hydration alone don’t actively remove heat, and relying on ice packs only provides slower, localized cooling and is less effective for overall core temperature reduction.
