What are the signs and symptoms of heat exhaustion?

Heat exhaustion is a condition caused by excessive heat exposure, leading to dehydration and an inability of the body to cool itself adequately. The signs and symptoms of heat exhaustion typically include heavy sweating, extreme weakness, and dizziness. Heavy sweating indicates that the body is trying to cool itself down, while extreme weakness and dizziness are responses to the loss of fluids and electrolytes. These symptoms highlight the body's struggle to cope with overheating and represent a critical point at which intervention is necessary to prevent progression to heat stroke. Recognizing these symptoms is essential for effective management and response to the condition, allowing for timely hydration and cooling measures to be implemented.
