Wim Hof

Wim Hof is a Dutch extreme athlete, most known for his ability to withstand prolonged exposure to freezing temperature, thus earning him the nickname “The Iceman”. He has set previously unbeaten Guinness World Records for swimming under ice, prolonged full-body contact with ice, which he has attempted over 16 times with the longest being for 1 hour 42 minutes, and for barefoot half-marathons on ice and snow. The Wim Hof Method that he has developed to undertake such feats include frequent cold exposure, various breathing techniques, yoga and meditation, and he has also claimed that it can safeguard against many medical conditions, though it is yet to be scientifically proven.
