What is a significant risk if heatstroke is left untreated?

Heatstroke is a severe and life-threatening condition that occurs when the body is unable to regulate its temperature, leading to a body temperature that rises to dangerous levels. If heatstroke is not treated promptly, the risk of severe complications increases significantly, including the potential for permanent damage to vital organs and systems within the body.

The correct answer indicates a staggering fatality rate, emphasizing the critical nature of heatstroke. When left untreated, the body's temperature can exceed 104°F (40°C), which can lead to brain damage and multi-organ failure. The 80 percent fatality rate highlights the urgent need for immediate medical intervention to cool the body and prevent irreversible harm or death.

Understanding the gravity of untreated heatstroke is vital for recognizing the need for prompt treatment. In contrast, while low blood pressure, fatigue, and vomiting can occur with heat-related illnesses, they do not reflect the same level of immediate danger or risk of mortality associated with untreated heatstroke.
