First and foremost, sparkling water does the exact same job as still water: it hydrates you. The carbonation is just carbon dioxide gas dissolved under pressure, not a secret potion that cancels out the H2O.
In fact, a 2026 study found that sparkling water is just as hydrating as the flat stuff during exercise. So if you think flat water is boring, sparkling is your new best friend for staying juicy.
The Digestion Dance
Here’s where it gets interesting: the bubbles can actually help your digestion. The carbonation stimulates the nerves in your stomach, which can increase swallowing frequency and reduce indigestion after a heavy meal.
A small study showed that people with chronic constipation found relief after drinking sparkling water for two weeks. Think of it as a gentle, non-medical nudge for your gut—like a tiny internal jazzercise class.
But here’s the catch: if you’re prone to bloating or have IBS, those same bubbles can make you feel like a human balloon. Listen to your body; it knows if you need a break from the pop.
