The first of the studies, published in the July 2009 issue of The Journal of Physiology, found that drinking fluids during exercise helps keep your cardiovascular system firing afterward. Typically, endurance athletes tend to experience a decrease in cardio efficiency and blood pressure, but staying hydrated mitigates these unhealthy effects.

In other hydration research published in the May 2009 Journal Biochemical and Biophysical Research Communications, South Korean scientists concluded that not only does dehydration impair exercise performance and increases DNA damage during exercise to exhaustion but that also replacing fluids — whether via water or a sports drink — prolongs your ability to exercise and reduces the oxidative stress to your body. Both studies make it clear that proper hydration (drinking properly filtered water) helps you work harder and recover better.
