How should suspected heat illness be managed in the field?

• A. Move to shade, hydrate, monitor core temperature, and apply cooling measures; treat heat stroke with rapid cooling
• B. Ignore symptoms and continue activity
• C. Increase activity to raise core temperature
• D. Administer cold drinks only

Answer: (A)

Managing suspected heat illness in the field centers on getting the person out of the heat, supporting cooling and hydration, and preventing progression to a more serious condition. Move to shade or a cooler environment and remove excess clothing to help heat dissipation. If they can drink, offer fluids to rehydrate; avoid forcing liquids if they’re nauseated or vomiting or if they are unconscious. Keep an eye on signs such as alertness, breathing, skin condition, and pulse, and monitor core temperature if you have a way to check it. Start cooling right away with whatever is available: evaporative cooling with water and fans can help, or more aggressive methods like cold-water immersion or placing ice packs on the neck, armpits, and groin to rapidly lower core temperature. For heat stroke, rapid cooling is essential, aiming to bring core temperature down toward 38–39°C, and you should summon emergency medical help promptly.
