heatstroke
Dangerous body overheating
Heatstroke is a dangerous condition caused by prolonged exposure to high temperatures, in which the body loses its ability to regulate heat.
Core temperature rises to dangerous levels, causing confusion, loss of consciousness, and potentially death if untreated.
Unlike heat exhaustion, heatstroke is a medical emergency requiring immediate cooling and professional care.
