I love hot showers -- probably a little hotter than is good for me actually. I don't know that I have taken an actual cold shower ever, although often in the summer months I'll take what I'd call "cool" ones. But aside from all the jokes that guys make about 'needing a cold shower,' have you ever thought of taking one for your health? Or how about instead of a cold shower a cold foot soak? This interesting article over at Natural Health suggests that alternating cold and warm foot soaks is like a mini strength-training session for your insides. The cold water (around 70º) constricts and tightens vessels, while the warm water (around 100º) loosens and expands them. Asking them to adjust quickly makes them stronger.

I'm guessing alternating cool and warm showers would do the same thing, but obviously that's not so easy. So are you buying this? The science seems sound enough to me, but then it also strikes me as more than a little unnatural.
