What heat-related illness is defined by a core body temperature of at least 104.9 F along with acute mental status changes?

Heatstroke is a severe and life-threatening condition that arises when the body overheats, typically due to prolonged exposure to high temperatures or strenuous exercise in hot weather. The defining feature of heatstroke is a core body temperature that rises to at least 104.9°F, which can lead to significant physiological dysfunction.

In addition to the elevated body temperature, heatstroke is characterized by acute changes in mental status, which may include confusion, altered consciousness, or even loss of consciousness. This neurological impairment occurs because the extreme heat can disrupt normal brain function and lead to cellular damage.

Understanding this condition is crucial because it requires immediate medical intervention to prevent serious complications or death. Early recognition of the symptoms associated with heatstroke, such as high body temperature and mental confusion, is vital for timely treatment, which may involve cooling measures and hydration to restore normal body function.
