Which symptom indicates a possible case of heat stress?

1. Increased energy

2. Dizziness

3. Cold sweats

4. High blood pressure

The correct answer is: Dizziness

Dizziness is a significant symptom that can indicate heat stress. When the body overheats and struggles to maintain a normal temperature, it can disrupt balance and lead to feelings of dizziness. This occurs due to factors such as dehydration, reduced blood flow, and changes in blood pressure, which can all happen during exposure to high temperatures. In contrast, increased energy would typically reflect the opposite of the fatigue and weakness often felt during heat stress, while cold sweats can be associated with various conditions and might not directly indicate heat stress. High blood pressure can occur in different situations but is not a definitive symptom of heat stress. Therefore, dizziness serves as a strong indicator of the body's response to excessively high temperatures and potential heat-related illness.
