I'm currently only taking cold showers, this is the third time I've started doing so. The very first one was quite an experience: my vision turned gray for a few seconds, I couldn't breathe, and I nearly fell over. The next day's was a little jarring but tolerable, and it kept on like that, a little less each day.
Then I fell out of the habit. My second and third times getting back into it, I didn't experience nearly the same drastic physiological effects, it was Day Two over and over again.
Do it gradually -- first one arm, shoulder; then the other arm, shoulder, then your front, then your head, then lastly your back. Don't dither about it, but don't dive into it either :-)
