What is a key symptom of heat stroke?

Unconsciousness is a key symptom of heat stroke, which is a severe form of heat-related illness. In heat stroke, the body’s temperature regulation fails, leading to a rapid and significant increase in core body temperature, typically exceeding 104°F (40°C). As the body overheats, the central nervous system can become affected, leading to confusion, disorientation, and ultimately loss of consciousness. This is often a critical condition requiring immediate medical attention.

The presence of unconsciousness in an individual experiencing heat stroke highlights the severity of the situation and the potential for serious complications, including damage to vital organs. Recognizing this symptom can be crucial in emergency response efforts to ensure timely and appropriate medical intervention.
