Fresh air is usually nicer than stale, old air. And when one sweats out "old water" it gets replaced by the fresh water one intakes. I bet if we collected enough sweat from sauna-goers and sprinters we would find things in it that you would rather have not in your body. Of course, I can already hear the chorus of indolence cheer "there's no science to support this claim" and yet there is also no science to deny it. The body is a gigantic circulatory system, out with the old, in with the new, I don't see why it would be any different with sweat.

Sweat does contain more than water and salt (urea for example). This is actually long established. But these substances are hardly toxins, even though the body has reasons excreting them.
It's still unclear how you think the concentration of these things on the skin will be lower with sweat dripping down (and evaporating) than when surrounded by a hundred liters of bathwater though.

My reasoning was pretty simple: if you sit in a bath things can leave your body and also have ample opportunity to re-enter your body. Your comment on relative concentrations is helpful and makes me reconsider this notion. As a naive and simple-minded person I think of entering a bath whilst covered in mud. Yes, the relative concentrations of mud on my skin's surface and mud in the water would clearly suggest I am "clean," but will I really feel clean stepping out of a tub that looks more opaque than clear? Maybe it is no surprise I have such trouble understanding the world with my simple-minded approaches.
