Which symptom is NOT associated with heat stress?

In the context of heat stress, sweating is actually a physiological response that occurs as the body attempts to regulate its temperature. When a person is exposed to high temperatures, sweating helps to cool the body down through evaporation. Therefore, sweating is not considered a symptom of heat stress; rather, it is a normal and expected reaction.

Dizziness, nausea, and confusion are indeed symptoms associated with heat stress. They occur due to the body's struggle to manage heat and can signal that the body is overheating. This can lead to more severe conditions if not addressed. Understanding the role of sweating in thermoregulation clarifies why it is not classified as a symptom of heat stress.
