The Iceman is back. Wim Hof is a Dutch world record holder, adventurer and daredevil, nicknamed “the Iceman” for his ability to withstand extreme cold. He holds twenty world records – including a world record for longest ice bath, and has stayed immersed in ice for as long as 1 hour and 52 minutes and 42 seconds. In 2007, Wim attempted, but failed (due to a foot injury), to climb Mount Everest wearing nothing but shorts. Then, in 2009, he reached the top of Mount Kilimanjaro in his shorts within two days. In 2009, Wim also completed a full marathon above the polar circle in Finland, in temperatures close to −20 °C (−4 °F) – dressed in nothing but shorts. He finished the marathon in 5 hours and 25 minutes. In  2011, Hof also ran a full marathon in the Namib Desert without water.  And in this most Vice video Wim demonstrates how he can consciously alter his immune system activity using a combination of breathing and cold.
