Which of the following is NOT a symptom of heat exhaustion?

1. Dizziness

2. Nausea

3. Severe headache

4. Increased heart rate

The correct answer is: Severe headache

Heat exhaustion is a condition that occurs when the body becomes overly heated, often due to prolonged exposure to high temperatures combined with physical exertion. The symptoms typically include dizziness, nausea, and an increased heart rate, which are direct physiological responses to the body’s attempts to cool itself and manage stress. Dizziness is a common symptom as the body loses fluids and electrolytes, leading to lower blood pressure. Nausea can arise because of overheating and dehydration, prompting an upset stomach. An increased heart rate occurs as the heart works harder to pump blood towards the skin in an effort to dissipate heat through sweating. In contrast, a severe headache is not typically associated with heat exhaustion. It may signal other issues, such as dehydration or a migraine, but it does not fall under the classic symptoms of heat exhaustion itself. Recognizing these symptoms is vital for any tow truck operator or outdoor worker to ensure safety and proper responses to heat-related illnesses.
