Staying hydrated during exercise is important. And a valuable term to remember is "drink to thirst."
"You can become dehydrated if you take in too little. And you can actually cause problems, such as exercise-induced low sodium or hyponatremia, if you take in too much," says Dr. Sara Filmalter, a Mayo Clinic family physician. "So the general rule of thumb at this point among physicians is to drink to thirst."
Rather than planning out arbitrary amounts of fluids during your workout, your body is the best indicator when you need hydration. Drink when you're thirsty.
"I typically recommend that they consume about half their fluids in water and half their fluids in a beverage that contains electrolytes without an enormous amount of sugar," says Dr. Filmalter.
When you sweat, your body is losing fluid, along with those electrolytes, such as sodium and chloride.
"The purpose of rehydrating is using water or, even better, those electrolyte-containing beverages to pull fluid back into our system and rehydrate so our organs are happy," says Dr. Filmalter.
So during that next workout, remember to drink to thirst and hydrate your body with sports beverages and good old H20 .
