What heat emergency do you cool the casualty's body by sprinkling the him or her with water?

In a heat emergency, such as heat exhaustion or heat stroke, cooling the casualty's body can be effectively achieved by sprinkling them with water. This method helps lower their body temperature through evaporation, especially when combined with fan use to enhance cooling. It's crucial to also move the person to a cooler environment and provide hydration if they are conscious and able to drink. Immediate medical attention may be necessary for severe cases, particularly heat stroke.
