Describe the signs and symptoms of heat exhaustion.

The signs and symptoms of heat exhaustion typically include heavy sweating, weakness, nausea, and dizziness. Heavy sweating is the body's natural response to overheating, as it works to cool itself down through evaporation. Weakness often follows due to dehydration and electrolyte loss, which diminishes physical performance and contributes to the overall feeling of fatigue. Nausea can occur as the body's systems react to stress and dehydration, impacting digestive function. Dizziness may signal that the body is struggling to maintain adequate blood flow and oxygen to the brain, also linked to dehydration and potential heat-related illnesses.

Additional options may present other symptoms associated with different conditions, such as heat stroke or muscular issues, complicating the clinical picture but not accurately describing the typical presentation of heat exhaustion. Recognizing the primary symptoms in the context of heat-related conditions is essential for ensuring timely intervention and management.
