Summer mystery solved: Does carbonated water actually keep you hydrated?

If you’ve spent a summer in Austin’s humid hellscape, you’ve been excruciatingly parched. And if you have refined tastes, you’ve probably had the urge to reach not for the tap, but for a frosty Topo Chico, or perhaps a chilled La Croix. That kicks off a whole other quandry once your brain, restored by two parts hydrogen, one part  oxygen and one part bubbles, asks a pressing question: Wait, is sparkling water actually doing anything to hydrate me?

Dallas-area TV station WFAA has the answer: Yes. According to a University of North Texas at Dallas professor interviewed by the station, carbonated water hydrates your body the same as still water, assuming your drink doesn’t have any added salt, sugar or other ingredients. Drinking several Topo Chicos a day can add a marginal amount of sodium to your diet, according to WFAA.

As for other health concerns? Calcium loss is only a concern with caffeinated beverages, and studies show low levels of tooth enamel erosion from sparkling water, WFAA reports.

Now, if you’ll excuse us, we have a few cases of fizzy water to pour down our gullets.
