      What if I want to get outside and be active?

      Exercising in heat leads to a lot of fluid loss from the body. It’s been shown that you need to drink at least the equivalent of the fluid lost to maintain a healthy body. Here are some general guidelines:

      • Allow 8-12 hours of recovery time from previous activity
      • Drink 16-20 ounces of fluid 4 hours prior to activity
      • Drink according to your thirst during exercise, but not more than 800 mL
      • If exercising for more than 45 minutes, include a drink with carbohydrates such as a sports drink
      • Post exercise, drink 16-24 oz of fluid for every pound lost

      What to do if you get heat exhaustion:

        • Get out of the heat and rest in a cool place
        • Take a cool bath or shower
        • Drink plenty of fluids
        • Loosen your clothing
        • Seek medical attention
