Name two commonly used cooling methods in firefighter rehab.

• A. Cold-water immersion and evaporative cooling (wet cooling with fans or cooling towels)
• B. Oral rehydration salts only
• C. Ice packs only on wrists
• D. Dry heat therapy

Answer: (A)

When firefighters finish strenuous work, cooling them quickly is essential to prevent heat illness from progressing. Two commonly used cooling methods in rehab are cold-water immersion and evaporative cooling. Cold-water immersion submerges the body in cool water, sometimes with ice, and pulls heat away from the core much faster than other methods. It’s the most rapid way to lower core temperature when setup permits, and it’s used under supervision with monitoring to ensure safety. Evaporative cooling combines spraying or misting water on the skin with air movement from fans or the use of cooling towels; the evaporation of water from the skin helps transfer heat away from the body and is very practical when full immersion isn’t available. Other approaches, like relying on oral rehydration alone, only address fluids, while localized cooling (like ice packs on wrists) cools small areas and doesn’t effectively reduce overall body temperature. Dry heat therapy would add heat rather than remove it.
