What are the typical signs and symptoms of heat exhaustion?

The typical signs and symptoms of heat exhaustion include heavy sweating, weakness, dizziness, nausea, and headache. These symptoms occur as the body overheats in response to prolonged exposure to high temperatures or physical exertion in hot environments. The body’s mechanisms for regulating temperature are overwhelmed, leading to dehydration and an electrolyte imbalance. As a result, heavy sweating is the body's way of trying to cool itself down, and it can lead to weakness and feelings of dizziness as hydration levels drop. Nausea and headache are also common as the body struggles to maintain homeostasis. Recognizing these symptoms is critical for timely intervention, such as moving the person to a cooler place and providing hydration, to prevent further complications like heat stroke.
