What is the function of applying a cold pack to a person suffering heat exhaustion?

The primary function of applying a cold pack to a person suffering from heat exhaustion is to lower body temperature. Heat exhaustion occurs when the body loses excessive amounts of water and salt through sweating, leading to a core temperature that can rise dangerously high. By applying a cold pack, you help to facilitate the body's cooling process, reducing the core temperature more rapidly and alleviating the immediate symptoms of heat stress.

Lowering the body temperature is crucial because prolonged exposure to elevated temperatures can lead to more severe conditions, such as heat stroke, which is a medical emergency. Therefore, timely application of a cold pack aids in stabilizing the individual's condition, preventing further health complications associated with overheating. This approach is part of first aid measures focused on quickly and effectively managing heat-related illnesses.
