Which of the following are signs and symptoms of heat stroke?

Heat stroke is a severe and potentially life-threatening condition that occurs when the body overheats, typically due to prolonged exposure to high temperatures or strenuous physical activity in hot weather. The body's cooling mechanisms become overwhelmed, leading to a series of physiological changes.

One of the hallmark signs of heat stroke is the absence of perspiration, which occurs because the body's ability to sweat is impaired. Under normal circumstances, sweating helps regulate body temperature; however, during heat stroke, the temperature control mechanisms fail, and the body stops producing sweat. This results in dry skin, which can feel hot to the touch, contributing to the risk of further elevating core body temperature.

This lack of perspiration is a critical indicator in diagnosing heat stroke, distinguishing it from other heat-related illnesses such as heat exhaustion, where sweating typically continues. Recognizing this symptom is crucial for timely intervention and treatment, as heat stroke can rapidly lead to serious complications, including organ damage or even death, if not addressed promptly.
