Growing up in Peru I got used to taking cold showers, we didn't at the time have a heating system in the house like we do now ("we" being my relative. I don't live there anymore) it wasn't nearly as cold as NJ cold water though! but I can't stand hot water.
My gf and I can't even take showers together because of our temp preferences. I mean, don't get it twisted, a playa still jumps in the shower, takes care of bidness then allows the lady to exit so he can rinse polar-bear style. I know you didn't need to know that, but I needed to say it.
I'm up for the challenge of taking cold showers as opposed to just cold rinses as I currently do. So, the water is supposed to be cold the entire time? looks like I'm gonna cut my shower time in half. I'll start tonight. I hear cold baths are supposed to help a lot with recovery and limiting soreness, so I'll pay attention to that even though it won't be the same.
