What is a symptom of heat stroke in addition to elevated body temperature?

A symptom of heat stroke, in addition to elevated body temperature, is confusion. When the body's temperature rises to dangerous levels, it can affect the central nervous system, leading to altered mental status, disorientation, or confusion. This neurological impact occurs because extreme heat can lead to swelling of brain cells, disrupting normal functioning.

In the context of heat stroke, while other symptoms like rapid, weak pulse, excessive sweating, and nausea are associated with heat-related illnesses, they may not specifically indicate heat stroke. For instance, excessive sweating typically occurs in heat exhaustion, which precedes heat stroke. Therefore, confusion stands out as a critical sign that heat stroke is affecting mental functioning, requiring immediate medical attention.
