What cooling method is appropriate for heat stroke in the field?

• A. Cool water immersion or fans.
• B. Apply hot packs.
• C. Give warm drink.
• D. Do nothing.

Answer: (A)

Rapid cooling is essential when dealing with heat stroke in the field. The fastest, most effective way to bring down the body's core temperature is cool water immersion, which cools the entire body quickly and can prevent serious organ damage. If immersion isn’t practical, evaporative cooling with fans and cool water applied to the skin is the next best approach, helping heat to dissipate through sweating and evaporation. These methods directly address the dangerous elevation in body temperature. Options that add heat or do nothing are harmful in this situation. Hot packs raise temperature further, a warm drink increases body heat and may not be safely swallowed in heat stroke, and doing nothing allows temperature to remain high and worsens the risk of brain and organ injury. In all cases, remove excess clothing, keep the person shaded, and seek emergency care while continuing cooling.
