They usually happen during a heat wave or in a hot climate, but can also occur when you’re doing very strenuous physical exercise.

HEAT STROKE

Heat stroke is a condition marked by fever and often by unconsciousness, caused by failure of the body’s temperature-regulating mechanism when exposed to excessively high temperatures. Heat stroke is also known as sun stroke. Heat stroke is a severe heat illness, defined as hyperthermia with a body temperature greater than 40.6 Celsius (105.1 Fahrenheit) because of environmental heat exposure with lack of thermoregulation. Heat stroke is distinct from a fever, where there is a physiological increase in the temperature set point of the body. The term ‘stroke’ in “heat stroke” is a misnomer in that it does not involve a blockage or hemorrhage of blood flow to the brain.

SYMPTOMS OF HEATSTROKE

  • High body temperature: A body temperature of 104 Fahrenheit (40 Celsius) or higher is the man warning sign of a heat stroke.
  • Altered mental state or behavior: Changes in brain function, such as confusion, memory loss, defects in judgment or thought, unusual or strange behavior.
  • Alteration in sweating: In heat stroke brought on by hot weather, your skin will feel hot and dry to touch.
  • Nausea and vomiting: In heat stroke you may feel sick to your stomach.
  • Flushed skin: In heat stroke your skin may turn red as your body temperature increase.
  • Rapid breathing: Your breathing may become rapid and shallow.
