You've probably heard that cold showers are good for you. Until this article by Tony Robbins I didn't really know how to start.
I suppose this is part of what makes Tony Robbins Tony Robbins. He gets you over the hump of doing things that you know you should have been doing all along.
After 3 days of cold'ish' showers I'm not yet converted, but I'm willing to keep trying.
I have to admit though--while I'm freezing my[self] in the shower--I am constantly thinking that the relaxation of a warm shower must have health benefits that offset the stress of this exercise. Time will tell.
