How long were you in there?

I do weekly ice baths, once a week every Sunday, using my bathtub. I'm unable to make my water close to 0C though, as I fill the tub with cold water from the tap (around 6-7C) and dump all the ice from my freezer ice maker to lower the temperature as much as possible (I think it gets to around 3-4C). I usually stay in there for 12-15 minutes, then take a very hot shower right after. My body still shivers after the hot shower. But I agree ice bath is a great experience.
