Heatstroke
Symptoms of Heatstroke
Dizziness, light-headedness, weakness, clumsiness and poor coordination, fatigue, headache, blurred vision, muscle aches, nausea, and vomiting (which are also symptoms of heat exhaustion) are common warning symptoms of heatstroke. Affected people do not sense that body temperature is greatly elevated. During heatstroke, the skin becomes hot, flushed, and sometimes dry. Sweating may or may not occur, despite the heat. Because of brain malfunction, people may become confused and disoriented and may have seizures or go into a coma. The heart rate and breathing rate increase. The pulse rate is usually rapid. The blood pressure may be high or low. Body temperature usually exceeds 104° F (40° C) and may be so high that it exceeds the markings on a typical thermometer.
