When the dog days of summer are upon you, some may be tempted to while away the time inside, while others going being outside to play and exercise. Doctors at UT Southwestern Medical Center at Dallas say it's important to respect the sun and summer heat while working out or playing sports. This happens when the body produces heat faster than it can remove it.
Prevention is simple.
Drink lots of liquids before, during and after you work out. If you have a big race or tennis match coming up, increase your fluid consumption about 24 hours before the event. Drink about a pint of liquid 2 hours before to get your body ready to process the added fluid. You'll want to drink regularly as you work out to replace the water you lose while you sweat. What you drink doesn't have to be ice cold, but should at least be cooler than the surrounding temperature.
