Does sparkling water hydrate you as much as flat water?

Yes.

Water is water.

You should avoid drinking too much mineral water.

“Sparkling water hydrates the body just as well as regular water. The only difference, as mentioned in section one, is that sparkling water has carbon dioxide added to it. Many athletes, though, won’t drink enough sparkling water to rehydrate after workouts, because the carbonation makes them feel full well before they have replaced the water they lost during exercise, so maintain caution and don’t use sparkling water as your only rehydrating method after exercise.”

You should also bear in mind that carbonation makes the water acidic and therefore can damage the enamel of your teeth.

No, and what’s more it is more acidic than still water and bad for your teeth, it also can also cause wind and burping!!

@Lightlyseared :)))

So water’s not water, it can sometimes be only water-like. Good info—thanks for clarifying ‘cause I love sparking water.

The bottle contains less H2O than normal water b/c some of liquid is actually CO2 gas. So, it is not as hydrating as the same measure of pure water.

@Afos22 not true. The CO2 is dissolved in the water it’s not taking up space in the bottle.

@Lightlyseared Is it not in the bottle?

Yes the CO2 is in the bottle but and its a big but on a atomic level molecules are mainly composed of nothing ie the space between the nucleus and the electrons so the extra CO2 will sit between the water molecules without taking up any measurable space (by standard human terms).

It still takes up space. If you had the same measure of sparkling water and “flat” water, you still have more H2O molecules in the flat water because some of the volume of the sparkling water comes from the CO2 that “sit between the water molecules”.

@Afos22 and @Lightlyseared, Yes, the CO2 does take up space, and does not simply “sit between molecules”, at least not without some effect. However, the actual space taken up is incredibly minuscule. Seriously, we’re on the scale of displacing maybe a few dozen molecules. Perhaps up to a hundred or two. You’d have to have, maybe, the entire Atlantic ocean’s worth of carbonated water to really notice the difference without some expensive and complex machinery.

@Lightlyseared and @BoBo1946 The carbon dioxide does acidify the water, but again, it’s a small amount. I’d be surprised if it caused much of an effect without long-term, high-level exposure. Like, drinking a few bottles every day for several years. If you have evidence to the contrary please let me know, but intuitively that doesn’t quite make sense. Also keep in mind soda =/ sparkling water. Soda has a ton of other stuff which could very well acidify the drink to noticeable levels.

In general, I’d agree with @marinelife. The biggest effect is sure to be the carbonation in your stomach, you simply can’t down enough after a lot of exercise without running out of room in your stomach. So after exercise, it’s bad, but in general it’s probably fine.

Yes.
