Somewhere along the line, a rumor started that carbonation “dehydrates” you. It sounds logical, right? Bubbles feel aggressive, so maybe they’re stealing your water. But that’s like saying a loud laugh dries out your throat more than a whisper. It’s just a different vibe.
Your kidneys don’t read the label. They don’t say, “Oh, this water came with CO2, better flush it out faster.” A study in the American Journal of Clinical Nutrition confirmed that sparkling water is just as hydrating as regular water after exercise. Science backed the fizz.
So if you’ve been chugging LaCroix thinking you’re pulling a fast one on hydration, relax. You’re not shortchanging your cells. You’re just hydrating with a little swagger.
The Real Enemy: Your Own Brain
The actual problem isn’t the bubbles—it’s that people replace water with soda, thinking zero-sugar bubbly water counts the same. It does, but only if you drink enough of it.
