What signifies heat exhaustion?

Heat exhaustion is characterized by the body's response to prolonged exposure to heat, often accompanied by loss of fluids and electrolytes. One of the hallmark signs associated with heat exhaustion is cool, moist, pale skin. This occurs because the body is attempting to cool itself through sweating, which leads to moisture on the skin's surface. The skin may appear pale due to reduced blood flow as the body diverts blood to the core to protect vital organs.

In heat exhaustion, individuals may feel weak, dizzy, or nauseated, and their skin can feel cool despite the high environmental temperature, presenting a clear indicator of the body's struggle to maintain its temperature balance. The cooler skin contrasted with severe overheating symptoms effectively signifies heat exhaustion, making it the most accurate choice.
