Heatstroke vs. Heat Exhaustion What’s the Difference?

With summer temperatures climbing into the 90’s in North Florida, your risk of suffering from heat exhaustion and heatstroke also rises. Both heatstroke and heat exhaustion are serious conditions and it’s important to know the difference between the two and when to seek treatment.

 

Heat Exhaustion

Heat exhaustion is a condition caused by exposure to high temperatures for an extended period of time. It’s often accompanied by dehydration. While it’s less serious than heatstroke, it’s important to act quickly when you recognize the symptoms. Heat exhaustion can lead to the more dangerous heatstroke without treatment.

 

Symptoms of Heat Exhaustion

  • Headache
  • Dizziness and/or faintness
  • Heavy sweating
  • Cool and clammy skin
  • Nausea or vomiting
  • Weak, rapid pulse
  • Muscle cramps
  • Excessive thirst
  • Fatigue

 

What to Do

  • Move to a cooler place
  • Hydrate with cool water or sports drinks
  • Stop all activity and rest

  • Loosen tight clothing

 

If symptoms worsen or continue for more than an hour, visit MedOne, your local St. Augustine Urgent Care Center for treatment.

  • Removing excess clothing
  • Cooling them with a cold shower or bath
  • Applying cold compresses or ice packs to armpits, groin, neck and back areas
