Thanks Roland and Francios,

That explains alot and it's facinating. It brings up another thought, I wonder if this cycle we put ourselves through, which is pretty rigorous depending on the temperature, length of time in the water, body fat content etc. could be considered conditioning in a positive sense. Or is it potentially detremental, over-taxing hormone production or kidney function.

I'm hoping it's good contitioning, as we age for instance. Repetitive self induced high blood pressure episodes and the healthy responses to them condition us for High Blood pressure episodes which are induced by age, diet, or Street fights? (I'm not suggesting you piss yourself before an altercation of some sort!) More like stressful situations are handled better metabolically due to our conditoning. Any opinions?
