Sparkling Water Is Just as Hydrating as Still

A 2016 American Journal of Clinical Nutrition study that compared still water with 12 other beverages (including seltzer, cola, OJ, hot and iced teas, coffee, lager beer, and a sports drink) found that bubbles don't inhibit your body's ability to quickly get the hydration it needs. So your eight daily glasses can include a few cans of pamplemousse fizz.
