Which of the following is a common symptom of heat stress?

1. Dizziness and fainting

2. Increased appetite

3. Cold extremities

4. Enhanced focus

The correct answer is: Dizziness and fainting

Dizziness and fainting are indeed common symptoms of heat stress. Heat stress occurs when the body becomes unable to properly cool itself, often due to exposure to high temperatures, physical exertion in hot conditions, or dehydration. As the body's temperature rises, the cardiovascular system is challenged, which can lead to inadequate blood flow to the brain. This results in symptoms like dizziness and lightheadedness, and in severe cases, individuals may faint. Recognizing these symptoms is crucial, as they indicate that the body is struggling to cope with heat, and immediate action may be necessary to prevent more severe heat-related illnesses. The other symptoms listed do not typically align with heat stress; for example, increased appetite is not a response to heat but rather a sign of normal physiological function. Cold extremities can indicate a lack of proper blood flow or could be related to other conditions, not typically associated with heat stress. Enhanced focus is also not a symptom of heat stress; in fact, heat can lead to reduced cognitive function and concentration.
