What are the signs of heat exhaustion?

Heat exhaustion is a serious condition that occurs when the body overheats, often due to prolonged exposure to high temperatures, particularly when combined with high humidity. Understanding the signs of heat exhaustion is crucial for prevention and early intervention.

The presence of heavy sweating, weakness, cold or clammy skin, and nausea are all key indicators of heat exhaustion. Heavy sweating occurs as the body attempts to regulate its temperature, while cold or clammy skin indicates that the body is struggling to maintain proper thermoregulation. Weakness is a direct result of the body losing fluids and electrolytes through excessive sweating, which can lead to feelings of fatigue and lethargy. Nausea is a symptom that can arise from an imbalance in the body's system due to overheating and dehydration.

Other options present symptoms that either do not typically occur in heat exhaustion or have other explanations. Recognizing the specific signs associated with heat exhaustion allows for immediate action, which can include moving the affected person to a cooler environment, encouraging hydration, and monitoring for more severe heat-related illnesses.
