A lot of commenters suggest to do something else instead of taking cold showers. I don't see the need to trade cold showers with anything as you certainly are able to e.g. lift weights AND take cold showers! Why not get the benefits of both?
If nothing else, taking cold showers at least prepares you to having a swim in cold water (in a hole in the frozen sea) while attending sauna during winter time in Finland.. :-)
