Hells yea!! So I usually jump straight into the shower after the plunge, and I actually cannot have the usual hot showers I like to have anymore. The maximum I can take is a cool/slightly luke warm shower. That's the most obvious difference for me so far, body temperature wise. The weather's been pretty decent, so it's hard to gauge if I can take the cold better nowadays. Mentally though, I can see how much this has boosted me in pretty much every way so far.
