Drink Up!

Whether we’re running, playing sports, riding a bike, exercising, hiking on a trail or working outdoors, paying careful attention to proper hydration — especially in the warmer months — is critical to our health. When it’s warm, our bodies perspire more to help cool us down. Proper fluid levels are important for ensuring a good flow of oxygen and red blood cells to our muscles and organs. During exercise and activity, we also lose valuable nutrients and minerals. These include sodium, magnesium and potassium, which help keep our muscles working properly, reduce fatigue and prevent dehydration.

Thirst alone shouldn’t be our barometer for measuring fluid loss. The rule of thumb should be to drink plenty of liquids before, during and after each activity.

A good guideline to use when preparing for an outdoor workout is to drink about two cups of fluid two hours before the activity. That helps make sure we are well-hydrated before we even go outdoors. Then, during the activity, we should drink four to six ounces every 15 to 20 minutes to keep our muscles well-hydrated. If planning an hour-long walk or gym workout, take a water bottle with about 16 ounces (two cups). Then, after exercise, drink again.

Fluids are vital to help our muscles function throughout our activity, but so is our blood sugar. Eat a light meal or snack of at least 100 calories about an hour or so before an activity. The nutrients from the snack will help keep hunger from interfering. The best snacks combine healthy carbohydrates, protein, and a small amount of fat. Fruit, yogurt, nuts, and granola bars are all good examples.

Water or sports drinks?

For most outdoor activities, regular tap or bottled water does the trick. If activity lasts an hour or more, either fruit juice diluted with water or a sports drink will provide carbohydrates for energy, plus minerals to replace electrolytes lost from sweating.

Sports drinks like Gatorade, Powerade, and All Sport can provide a needed energy boost during activity. They are designed to rapidly replace fluids and to increase the sugar (glucose) circulating in our blood. However, read the label to determine which sports drinks are most effective. Ideally, it will provide around 14 grams of carbohydrates, 28 mg of potassium, and 100 mg of sodium per eight-ounce serving. The drink’s carbohydrates should come from glucose, sucrose, and/or fructose, rather than from processed sugar or corn syrup. These are more easily and quickly absorbed. It shouldn’t be carbonated, as the bubbles can lead to an upset stomach.

Most sports beverages are well-diluted and contain relatively few calories. If the flavor of a sports drink helps you maintain hydration, diluting it with water or pouring it into a thermos packed with ice will cut down even more on excess calories.

“Fitness waters” such as Propel are lightly flavored and have added vitamins and minerals. The additional nutrients are meant to supplement a healthy diet — not replace losses from exercise.

Fitness waters fall somewhere between the sports drinks and plain water in terms of being effective hydrators. They contain fewer calories and electrolytes than sports drinks, but offer more taste than plain water. Additionally, the so-called “designer, or super waters” are advertised as being enhanced with everything from vitamins, oxygen and glucose, to alleged fat-burning minerals. The FDA does not require proof of this kind of claim, but whatever helps keep you hydrated is worth considering…as long as you keep drinking!
