What heat emergency is characterized by hot and dry skin, mental confusion, and headache after a heavy workout?

The characteristic signs and symptoms of heat stroke include hot and dry skin, confusion, and headaches, especially after intense physical exertion, such as a heavy workout. In heat stroke, the body’s temperature regulation fails, and it can no longer shed heat effectively, leading to a dangerously high body temperature and altered mental status. Unlike heat exhaustion, where the skin may be cool and clammy and symptoms like heavy sweating occur, heat stroke presents with epithetically dry skin due to the body's inability to sweat. The presence of mental confusion is particularly critical; it indicates severe physiological distress and the potential for life-threatening consequences if not treated promptly. Thus, the combination of these symptoms pinpoint heat stroke as the accurate diagnosis in this scenario.
