Know the Warning Signs of Heatstroke

Heatstroke is a very dangerous condition caused by the body overheating. It requires immediate treatment as it can be life-threatening. Look for these warning signs:

  • High body temperature. A body temperature of 104 degrees F or higher is the main sign of heatstroke.
  • An altered mental state. Signs include confusion, slurred speech, agitation, irritability, delirium, seizures and coma.
  • Skin changes. In heatstroke brought on by hot weather, the skin will feel hot and dry to the touch. In heatstroke brought on by strenuous exercise, the skin may feel moist.
  • Rapid breathing. Breathing may become rapid and shallow.
  • Flushed skin. The skin may turn red as the body’s temperature increases.
  • Nausea and vomiting. A heatstroke victim often feels sick to their stomach.
  • Heatstroke often causes a throbbing headache.
  • Racing heart rate. The heart beats faster in an effort to use blood to cool the body.
