Which of the following is a common method to cool someone suffering from heat stroke?

Applying ice packs to certain body areas is a well-recognized and effective method for cooling someone suffering from heat stroke. This approach works because ice packs can help lower the body temperature rapidly by applying cold directly to areas that are more effective for heat exchange, such as the armpits, neck, groin, and back. These areas are rich in blood vessels, making them ideal spots for facilitating the cooling of the blood circulating throughout the body.

The use of ice packs helps to reduce the core body temperature quickly, which is critical in cases of heat stroke, as high body temperatures can lead to serious health complications or even be life-threatening. Rapid cooling is essential because the body's normal thermoregulatory processes are overwhelmed during a heat stroke incident.

In contrast, other options do not aid in cooling the body effectively. Providing a warm drink, wrapping someone in heavy blankets, or leaving them in direct sunlight would exacerbate the condition by raising body temperature and preventing the body from cooling down. Hence, applying ice packs is a clear and practical method for treating heat stroke effectively.
