The internet is awash with advice on how to get used to cold water. As so often happens, the first thing you see is a paid course, a “unique method”, cold therapy, biohacking or a workshop where you spend several thousand crowns learning that cold water is cold and that you should breathe properly while you are in it.
While reviewing the website, AI challenged what I had written about experienced cold-water swimmers jumping into icy water. Rather than letting it rewrite the text automatically, I asked for a single well-documented case, followed by a precise examination of the studies behind its position. The outcome was more than a simple yes or no: it was a much clearer distinction between a measurable bodily response and clinically dangerous cold-water shock.
