Which statement is true about heat stress?

The statement about the lack of sweat being a symptom of heat stroke is accurate. When an individual experiences heat stroke, their body's normal thermoregulation becomes disrupted, and one of the signs is indeed the cessation of sweating, even though the body temperature can rise dangerously high. This lack of perspiration signifies that the body's cooling mechanisms are overwhelmed or have failed entirely, which is a critical indicator of heat stroke that requires immediate medical attention.

Understanding this symptom is crucial for recognizing heat-related illnesses, as individuals may not realize how severe their condition has become. Highlighting the difference between heat exhaustion and heat stroke is particularly important, as heat stroke demands more urgent intervention due to the risk of mortality and severe health consequences. The other statements either misrepresent symptoms or fail to grasp the relationship between personal protective equipment (PPE) and the risk of heat stress.
