Some people swear by still water, while others can’t get enough of the fizz. But when it comes to hydration, is one better than the other? Let’s break it down.

IS SPARKLING WATER AS HYDRATING AS STILL WATER?

Short answer: Yes! Carbonated water is just as hydrating as still water (even the flavored kind). While some research suggests that carbonation might slightly slow down absorption, this has no real impact on how well your body stays hydrated. In other words, those bubbles aren’t getting in the way of your hydration goals.

According to Professor Ronald Maughan from St. Andrews University School of Medicine, sparkling water hydrates just as well as regular water. A 2016 study he co-authored found no real difference in fluid retention between the two after four hours—so those bubbles don’t affect hydration!

IS SPARKLING WATER AS HYDRATING AS STILL WATER DURING EXERCISE?

While still water is usually the go-to choice for workouts, that’s more about comfort than hydration. The carbonation in sparkling water can cause bloating or gas, which isn’t ideal when you’re mid-run or lifting weights. But if you prefer the fizz and it keeps you drinking more, go for it—hydration is what matters most.

IS SPARKLING WATER SAFE TO DRINK ALL DAY?

Yep! Sparkling water is totally safe to drink all day, whether it’s plain or naturally flavored. Even lightly sweetened options can be fine, as long as they don’t have too much added sugar or artificial sweeteners. Just keep in mind that carbonation can cause bloating for some people—so if that’s an issue, mixing in some still water might be a good idea!

THE FINAL VERDICT

Whether it’s still or sparkling, water is water. Both will keep you hydrated, and the best choice is simply the one you enjoy drinking more. So, if the bubbles make hydration more fun, sip away!
