I can totally recommend everyone at least try a cold shower once. It's has a bit of a lower barrier to entry than cold water swimming. If you've never been under a cold shower for more than a few seconds it's hard to imagine what it's like. It's more than just cold. Your entire body has a visceral reaction to it. Your heart rate goes up, your breathing quickens, fight-or-flight kicks in hard. It's not exactly fun but boy is it a good way to start your day. I've never been more awake than after a cold shower. Of course the tricky bit is to actually get yourself to do it. Personally I tend to shower nice and warm, and then finish it off by turning off the hot water. It's always a challenge to see how long I can last under the cold water. Big advantage of showering like this is that you still get to have a nice comfy long warm shower but getting out of the shower isn't cold anymore. Room temperature is positively pleasant after a cold shower ;-)
