isn't dehydration supposed to have lower Na levels? since the body tries to compensate by secereting ADH and aldosterone which retain Na in blood

Hello Evan great content, just what i was looking for one question I wanted to ask when we correlate this to %'s, you said anything over 1.020 would be considered dehydrated. where would we say an individual is 100% hydrated 90%, 80%. 70% and so on. hank you again for your time
