Heatstroke: Causes, Dangers & What to Do

Heatstroke is dangerous to people primarily because it can cause multiple organ failure and death if not treated promptly.

Heatstroke occurs when the body's temperature rises to dangerous levels, usually above 104°F (40°C). This can happen when the body is exposed to high temperatures, such as during a heat wave, or when the body is unable to cool itself properly, such as during strenuous exercise or in people with certain medical conditions.

When the body's temperature rises, it can cause damage to the brain, heart, kidneys, and other organs. Heatstroke can also lead to dehydration, electrolyte imbalances, and seizures.

Symptoms of heatstroke include:

* High body temperature

* Confusion or delirium

* Loss of consciousness

* Seizures

* Rapid heartbeat

* Difficulty breathing

* Nausea and vomiting

* Diarrhea

If you think someone is experiencing heatstroke, call 911 immediately. While waiting for help to arrive, try to cool the person down by:

* Moving them to a cool place

* Removing their clothing

* Applying cool water to their skin

* Fanning them

Heatstroke is a medical emergency. If you or someone you know is experiencing symptoms of heatstroke, call 911 immediately.
