Does Sparkling Water Hydrate You or Leave You High and Dry?

By Lily Newman on at

Sometimes people go on sparkling water binges. It happens. Between cold cans, two litre bottles and SodaStreams it can be hard not to become totally captivated by the bubbly stuff. But sometimes it feels like all those bubbles are getting in the way of hydration. So does your body absorb effervescence differently? Writer and obsessive fizzy drinker, Noah Davis, wanted to find out.

The topic hasn't been researched particularly extensively, and there isn't a lot of solid information online. So Davis contacted Susan Yeargin, a hydration expert and assistant professor in Athletic Training Education at the University of South Carolina. She and a colleague from University of Arkansas, dug through existing literature to find a rash of studies from the 90s all published in the International Journal of Sport Nutrition. The studies pretty much all concluded that sparkling water is just as good a hydrator as water, but a couple of papers did note that people may drink less sparkling water than water in a given sitting, thus reducing their overall hydration.

Some brief PubMed searching turns up the studies Davis mentions, plus a few others with similar results. It seems like it's safe to keep hitting the sparkling water hard, even with rumours of tooth enamel erosion and stomach lining issues flying around. Come on people, it's just bubbly water.
