Your Bladder (mine is much smaller).

What’s the most popular area of a CrossFit gym during a competition?  For me, it’s still, even after 30 years of athletics – the bathroom.  Anyone wonder why?  Here you go: 

Anxiety and stress activates your autonomic sympathetic nervous system (fight or flight).  This sympathetic response causes skin vasoconstriction – taking blood away from your gut and skin and moving it into the muscles where it’s needed (your hands ever get cold before an event or speech?) for you to either run or kick some ass.  This blood supply represents a large portion of your body’s blood volume, so when it suddenly gets constricted into a much smaller space, the fluid that was already there has to be flushed out. This fluid is funnelled into your bladder and as it accumulates it activates bladder stretch receptors stimulating the contraction of the bladder muscles – and thus – you have to go pee pee. There you have it.
