heatstroke

views updated

heatstroke A dangerously high body temperature (hyperthermia) — above 41°C or 106 °F — which may be accompanied by coma or convulsions, and requires emergency life-saving measures. The body has passed the limit of its heat-losing mechanisms. It may follow from the less serious condition of heat exhaustion due to excessive sweating and dehydration during heat exposure, usually with heavy work or exercise in a hot environment.
