Health Watch - Hot Summers: Hydration

Health Watch is a public service of the Office of News and Publications and is intended to provide general information only and should not replace the advice of a medical professional. You should contact your physician if you have questions about any of these topics.

This week on Health Watch, we're talking about hot summer weather and the health problems it can bring with it. If you need to exercise or be active in hot weather, the important thing to keep in mind is hydration.

Dr. Luis Palacios, a sports medicine expert at UT Southwestern Medical Center at Dallas, says heat stress and heat stroke are real dangers for athletes in hot weather. To prevent these problems, you need to drink 4 to 8 ounces of water every 15 to 20 minutes for exercise sessions of an hour or less. For longer workouts, you may need sports drinks that replenish carbohydrates and electrolytes such as sodium and potassium that are lost through sweat.

Proper hydration can save your life. It can also boost your workout. Dehydration impairs athletic performance.
