During rapid cooling for heat stroke, which areas are targeted with cooling measures?

• A. Wrist and ankles.
• B. Chest and back.
• C. Axilla, groin, neck.
• D. Shoulders.

Answer: (C)

Rapid cooling works best when you remove heat from sites where a lot of blood circulates close to the skin. The axilla (armpit), groin, and neck fit this pattern because they have large superficial blood vessels and relatively thin tissue over them. Cooling these areas quickly chills the returning blood, which speeds up lowering the core body temperature—crucial in heat stroke.

That’s why methods like cold-water immersion or applying cooling measures to the neck, armpits, and groin are emphasized for rapid temperature reduction. Areas such as wrists, ankles, or broad surfaces like the chest or back don’t remove heat as efficiently in this urgent setting, so they’re less effective focal targets for rapid cooling.
