How are sport drinks supposed to hydrate you more than drinking water?
In: Biology
When you sweat, you lose a lot of sodium. You may remember from high school bio, a cellular process called the sodium-potassium pump. It’s the way your cells hydrate. Since you’re losing so much sodium through sweat, you need more sodium to keep your cells hydrated, as well as potassium to keep the process in balance. That’s really all there is to it. The sugar actually does nothing but give you a temporary boost in energy and make the drink taste good – nothing to do with the hydration part.
