Heat Stroke

Definition – Heat Stroke is a condition when body temperature rises beyond a critical temperature into a range of 105-1080F. It is a form of hyperthermia in which the body temperature is elevated dramatically. The medical definition of heat stroke is a core body temperature greater than 104 degrees Fahrenheit, with complications involving the central nervous system that occur after exposure to high temperatures.


  • Dizziness,
  • Delirium,
  • Abdominal distress sometimes with vomiting,
  • Loss of consciousness,
  • Disorientation,
  • High body temperature.


  • Exposure to very high temp,
  • Hypothalamic heat regulating ability diminished.
  • Body Temperature (105-1080F)

Treatment: The most significant measures to prevent heat strokes are to avoid becoming dehydrated and to avoid vigorous physical activities in hot and humid weather. Heatstroke treatment centers on cooling your body to a normal temperature to prevent or reduce damage to your brain and vital organs.

  • Placing the person in a cold water bath,
  • Sponge or spray cooling of skin which decreases core temperature.

The diagnosis is almost always made by the patient’s symptoms, exposure to hot surroundings, and taking the core body temperature or rectal temperature.
