Exercise is essential for CF patients. It is important to take a few extra precautions to ensure that you get the greatest benefit from your activity.

Fluids
Drinking enough fluid is very important, especially during the summer. As a rule, patients should have 6 to 12 ounces of fluid 15 minutes before exercise and every 15 to 20 minutes during exercise. Fluids should always be available, and planned fluid breaks are very important. Fluids should not contain caffeine because it can cause dehydration. Sports drinks are a good choice because they provide carbohydrates for energy and small amounts of salt.

Salt
The extra salt that CF patients lose during exercise should be replaced with salty foods like potato chips. Do not rely on sports drinks alone to replenish salt lost during exercise because these beverages do not contain enough salt to meet CF patients' needs.

Extra Calories
When you exercise, you burn additional calories. You may need to add an extra snack (or two) to make up for the calories lost during exercise. It is very important to plan for this extra food so that you do not lose weight.
