The title implies that humans lack biological adaptations to swimming in cold water, but this isn’t true: we have an unusual amount of subcutaneous fat, the mammalian dive response, etc.
Like this article says- you need to be in good health and adapt your body to doing it over time, and it is fine. I’ve been practicing Wim Hof for a while, and can swim and freedive in ice cold water for quite a long time without any major issues. My body does not panic and tense up because I have learned how to relax and prevent that.
