2. Longest Full Body Ice Contact.
Wim Hof is no stranger to world records — he holds more than a dozen of them, from running a marathon in the notoriously brutal Namib desert without drinking water to swimming under a sheet of ice for over 200 feet (66 meters). But his craziest stunt is, perhaps, his record for the longest time spent in a full body ice bath, clocking it at 1 hour 52 minutes! Hof credits meditation with his remarkable success.
