Hallo, Stefan!

Zum Thema "TOIletten" erlaube ich mir, die englische Seite barefooters.org zu zitieren, in der Hoffnung, daß Du Englisch verstehst:

Q14: What about public restrooms, i.e., urine?
[The following was contributed by Mike Berrow.]
I avoid urine too, but that's due to the "yuck" factor that we were all brought up with and not due to any science. Urine is sterile and harmless. I pulled the following quotes from the web:

... Well, urine is not a toxic waste product and this has been scientifically proven. 95% of urine is water, 2.5% consists of urea and the remaining 2.5% is a mixture of minerals, salt, hormones and enzymes. Toxic substances are being removed from the body through the liver and intestines, through the skin and through the outbreath. The main function of the kidneys is to keep the composition of the blood in optimal balance. When there is to much water, the kidneys will remove it. But that doesn't make water into a toxic waste product ...
You can find urea in many skin products as one of the main components. Furthermore, urine is entirely sterile after secretion and has an antiseptic effect.

Many medical researchers, unlike most of us, know that far from being a dirty body-waste, fresh, normal urine is actually sterile and is an extraordinary combination of some of the most vital and medically important substances known to man. Now this fact may be unknown to the vast majority of the public today, it is nothing new to modern medicine.

If anything, the urea is probably good for your skin.
