Few things feel better than the summer sun after a long winter and rainy spring, but too much of this good thing can be dangerous.

We at Premier Urgent Care can help you understand the signs and symptoms of heat exhaustion and dehydration, how to treat it, and most importantly, how to prevent it, so you can enjoy every minute of your summer safely.

Heat Exhaustion & Dehydration

Heat exhaustion and dehydration often go hand in hand. Dehydration, which is a depletion or imbalance of fluids or electrolytes in the body, when coupled with extended exposure to sun or heat, can cause heat exhaustion.


If you know you will be exposed to high temperatures for an extended period of time, take these steps to prevent heat exhaustion and dehydration.

  • Drink plenty of water. The general daily water intake recommendation is eight 8-ounce glasses of water a day for women, and 12 8-ounce glasses a day for men. This guideline varies depending on the fluids a person is getting from food and other beverages, as well as their level of physical activity. As a rule, though, if you’re spending an extended period of time in high temperatures, you should consider eight glasses of water a day the minimum guideline.
  • Wear loose-fitting, comfortable clothes.
  • Cover up your skin from the sun as much as possible with clothing, hats, sun umbrellas, and always wear sunscreen. Sunburn or sunstroke can contribute to dehydration and heat exhaustion.
  • Limit physical activity. When the heat index is high, be aware that excessive physical activity (and sweating) increases your risk of dehydration and heat exhaustion.

  • Although mild heat exhaustion and dehydration can be treated without a trip to urgent care, the symptoms aren’t something to be taken lightly. Without proper intervention, severe heat exhaustion can progress to heatstroke, which can damage the brain and other vital organs, and even cause death. If your dehydration or heat exhaustion is severe, you may need a physician to administer IV fluids.
  • If you experience any of the severe heat exhaustion or dehydration symptoms listed above, or symptoms that persist greater than 30 minutes after self-treatment,  seek medical help.
