Know the Dangers of Heat Stroke


Watch this video about heatstroke.

No one is immune to heat stroke — it can happen to anyone and is one of the most dangerous yet avoidable heat-related injuries.

Heat stroke happens when your internal body temperature reaches 105° and your body is unable to cool down. Heat stroke or heat exhaustion can occur If you are exposed to long periods of heat. We recommend seeking immediate medical care if you show signs of the following symptoms:

  • Feel dizzy or faint
  • Are no longer sweating, but are still hot
  • Are nauseous or vomit
  • Have a rapid heartbeat
  • Intense headache, much worse than what you might normally feel when spending time in the sun
  • Mental confusion
  • Darker skin may turn gray

Hot, bright red skin can be sunburn. However, when it’s heat stroke you may experience other symptoms.

More serious symptoms include seizures and fainting, but are less common.

Recovery from heatstroke depends on the amount of time it takes the body to return its temperature back to normal.

  • Move out of direct sunlight. Try heading indoors or at least to the closest shady spot.
  • Take off any extra clothing.
  • Cool the body down with air, cool water and ice. Apply it to areas of the body with the most blood vessels such as the neck, back, groin and armpits.
  • Seek immediate medical attention

Here’s how you can avoid heatstroke:

  • Do not exercise outside in high heat, especially if you experienced heat stroke in the past, because you are at a higher risk of getting it again.
  • Drink. Drink. Drink! Checking the color of your urine is a good way to make sure you stay hydrated. If it is light — that’s good; if it’s dark, it may mean you’re not taking in enough liquids.
  • If you do exercise in heat, stop frequently drink breaks. Licking your lips a lot, sunken eyes or a having loss of energy are all signs of dehydration.
  • Wear light-colored clothes with light, loose fabrics.
  • Come inside when you feel hot.
  • Stay inside during the hottest hours of the day.
