an emergency condition where the body’s core temperature is markedly elevated

Heat stroke is an emergency condition where the body’s core temperature is markedly elevated (depending on who provides the definition, about 104 F [40 C] or above in adults and 105 F or 40.5 C in children) after being exposed to high environmental temperatures combined with neurological symptoms and loss of body thermal auto regulation (ability of the brain to control the body temperature).
