I’ve been taking cold showers for at least a year. Alaska’s tap water is ideal at 41°F in winter and 46°F in summer.
My feet used to get cold outside, but now I can wear summer shoes (with screws for traction) with one pair of regular socks comfortably in slightly below zero Fahrenheit
My hands still get cold though, which I’m finally now theorizing may be because my arms and hands don’t spend much time in the cold water, which I’m going to now change, whereas the feet are in cold water during the entire shower.
As a child, playing outside for hours in Minnesota, and downhill skied without a mask. I frostbit my fingers, toes and nose, and thought they’d never improve.
My toes seem back to normal now at age-63, thanks to Wim Hof and Alaska’s cold tap water!
Life giving therapy that costs nothing!
