What is heatstroke?

This is a life threatening emergency where the person's body temperature is dangerously elevated and they display neurologic abnormalities. This occurs when the body fails to regulate its temperature properly. It can be caused by the surrounding environment (heat, moisture) or internal factors (dehydration, strenuous exercise).

Symptoms of heatstroke

  • Living in a warm or hot environment

  • Seizure

  • Feel lightheaded

  • Fatigue

  • Nausea or vomiting

  • Fever

  • Pain over the temples

  • Forehead pain

Questions your doctor may ask to check for heatstroke

Your doctor may ask these questions to diagnose heatstroke

  • Do you live or work in a hot environment?

  • Have you had a seizure?

  • Have you had any lightheadedness recently?

  • Do you feel fatigued?

  • Do you have nausea or vomiting?

Treatment for heatstroke

Treatment for mild heat related illness starts with simple measures like resting in the shade, loosening clothing and drinking water. Heat stroke, by contrast, is a severe heat illness that requires emergency treatment. Patients can receive cool water immersion, cold fluids through the bloodstream, and evaporative cooling treatments.
