For over a century, Prussians have been diving and swimming in minus 22-degree weather. There is an argument that it is to mark the start of winter while other claims it rejuvenates the health. 76-year-old Jitka Tauferova has revealed that ice swimming has changed her whole life. “The last time I had flu was 25 years ago and my back pain disappeared. Better blood circulation improves healing broken bones, and my heart is like a hammer. I feel great.”
