What is the prompt treatment for heat exhaustion?

The prompt treatment for heat exhaustion is to cool the body and replace sodium and fluids. This condition occurs when the body loses more fluids and electrolytes than it takes in, usually due to excessive sweating in high temperatures.

By cooling the body, you help lower its core temperature, which is critical in preventing the progression to heat stroke, a more severe condition. Using cold packs, cool baths, or wet towels effectively aids in cooling. Additionally, fluid replacement with water or electrolyte-rich beverages is essential to restore hydration and replenish lost salts. This balanced approach addresses both the overheating and the electrolyte deficit that contributes to the symptoms of heat exhaustion.

The alternative approaches presented in other options either inadequately address the need for comprehensive cooling and hydration or suggest actions contrary to effective management of heat exhaustion. For instance, localizing cooling to just the neck and head does not adequately manage overall body temperature. Immediate bed rest may provide temporary relief, but without active cooling and fluid replacement, it limits recovery. Encouraging physical activity in this situation is counterproductive as it exacerbates the problems associated with heat exhaustion instead of providing relief.
