About swallowing saline sea...?

Is it more unhealthy to swallow saline water than to drink no hose at all? I know it dehydrates you, but I have an argument with a friend going on for this. She believes you dehydrates quicker with no marine...I say you dehyrate quicker if you drink brackish water, whether from the the deep or from water next to plain table salt added to it. Can anyone weigh contained by on this?? salt hose down dehyrates you quicker.
I remember after eating overly salted Chinese - I be desperately thirsty despite of having a cup of soda with a spread. After a normally Chinese, I wouldn't diligence less.
So, I reflect salt make it far worse.
Sea or table? I think it depends on the concentration, not on the type.
