Health Watch — Keeping Cool: 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.

Summer’s in full swing, and that usually means it’s hot outside. This week on Health Watch, we’ll talk about how you can keep your cool in the summer heat. One important thing you need to do to help cool your body is stay hydrated.

Lona Sandon, a registered dietitian at UT Southwestern Medical Center, says your body may need more fluid in the summer. That’s because the body cools itself by evaporating sweat. The more you sweat, the more fluid you need. Six to eight glasses of water a day is a good goal, but you may need more if you’re exercising or working in the heat. Keep a bottle of water with you as you exercise or work in hot weather and keep drinking. By the time you feel thirsty, you may already be dehydrated.

Dehydration can become a very serious problem very quickly. It causes weakness, exhaustion or delirium and can lead to worse problems such as heat exhaustion or heat stroke.
