Proper hydration during exercise and before competition isn't easy. Too little, and you can overheat, dehydrate, and do serious damage to yourself. Too much, and you can get ill, or even suffer from hyponatremia, a sometimes fatal condition. We talked to the experts to help you do it just right.
Chill your fluids.
The point of hydration is to increase blood volume and lower body temperature. Because of this, hydration expert Doug Casa says chilled fluids are more effective than those at room temperature. There are plenty of containers on the market designed to keep fluid temperature low. Cold slushy drinks have also become popular with athletes, and Casa says studies have proved their ability to lower body temperature and improve performance.
