What feeling commonly accompanies heat exhaustion?

Heat exhaustion is a condition that arises from prolonged exposure to high temperatures, often accompanied by dehydration. One of the hallmark symptoms of heat exhaustion is faintness or dizziness. This occurs because the body struggles to regulate temperature and maintain adequate blood flow to the brain due to heat stress and potential dehydration. As a result, individuals may feel weak, lightheaded, and experience a drop in blood pressure, leading to a sense of faintness.

The other options do not align with the symptoms associated with heat exhaustion. Euphoria is typically not a reaction to heat stress; it is more commonly associated with other psychological or physiological states. Extreme hunger can sometimes occur in conditions of dehydration, but it is not a primary symptom of heat exhaustion. Restlessness may be present in various conditions, but faintness and dizziness are more specific indicators of heat exhaustion that reflect its physiological effects.
