What temperature is deemed life-threatening?

A temperature above 105°F is considered life-threatening due to the potential onset of hyperthermia or heat stroke. At this elevated temperature, the body's thermoregulatory system becomes overwhelmed, leading to critical dysfunction of internal organs and systems. This can result in severe complications such as brain damage, seizures, or even death if not promptly addressed. The risk increases significantly as the temperature rises, emphasizing the importance of recognizing and treating high body temperatures in emergency medical situations.
