What are common signs of heat exhaustion?

1. Cool, moist, pale skin

2. Red, hot, dry skin

3. Rapid weak pulse

4. High body temperature

Heat exhaustion occurs when the body overheats due to prolonged exposure to high temperatures, often in combination with high humidity and strenuous physical activity. Recognizing the signs and symptoms of heat exhaustion is crucial for ensuring proper treatment and recovery. One of the hallmark signs of heat exhaustion is cool, moist, pale skin. This occurs because the body's mechanisms to cool itself through sweating are still functioning. The skin's coolness and moisture are signs that the body is attempting to lower its core temperature, despite the person feeling weak or fatigued. It's important to note that this symptom is indicative of the body's state before it reaches more severe conditions like heat stroke, which can present with dry and flushed skin. In contrast, the other options provided describe symptoms that are either indicative of other heat-related illnesses or uncommon in heat exhaustion. For example, a rapid weak pulse, while present in heat exhaustion, does not specifically represent the best-known symptom, which is the characteristic skin appearance. High body temperature may also be present, but it is not always high in cases of heat exhaustion and is more reliably associated with heat stroke. Red, hot, dry skin is a classic symptom of heat stroke, not heat exhaustion, as it indicates that the body's cooling mechanisms have failed and the situation
