Which of the following is a symptom of heat exhaustion?

1. STOP sweating

2. Increased body temperature

3. Excessive sweating

4. Confusion

The correct answer is: Excessive sweating

Heat exhaustion is a heat-related illness that can occur when the body loses excessive amounts of water and salt through sweating, typically due to prolonged exposure to high temperatures and strenuous activity. The hallmark symptom of heat exhaustion is excessive sweating, as the body attempts to cool itself down through perspiration. In this condition, the body's natural cooling mechanisms become overwhelmed, leading to an increased heart rate, weakness, fatigue, and nausea, in addition to excessive sweating. The individual may feel clammy or cool to the touch despite high levels of perspiration. Recognizing excessive sweating is crucial, as it indicates the body's struggle to regulate temperature and can serve as an initial warning of impending heat-related illness if not addressed promptly. Understanding this symptom helps in taking preventive measures and ensuring the affected individual receives appropriate care, such as hydration and cooling measures, to avoid progression to more severe conditions like heat stroke.
