Does soda really dehyrdate you?

[threeonefour]

it seems like EVERYONE i know thinks drinking soda dehyrates you. I hear sports people talk about it a lot (a reason why they drink gatorade instead of soda at a game or whatever). But whenever someone mentions this fact to me it just seems strange. I am not saying they are wrong, but you can only last a few days without drinking water(or some form of hydration) right? Well I know a lot of people who have gone at least two days drinking nothing but mountain dew (which is gross) or coke.

Now if soda really does dehyrdrate you, then that should be worse than drinking nothing at all. I am not saying they should be dead but they should be severely dehydrated right? It turns out that they seem to be doing fine after going on these soda binges.


so whats the real story. does soda only dehyradte you in the short term{the sodium dehydrates you faster than the water in the soda hyrdates but there is so much more water that eventually it hyrdrates you)? how does that work. Carbonated water is the number one ingredient on the can, shouldn't that be a hydrating agent(other than that its just sugar and sodium)?
