Wim Hof (born 20 April 1959) is a Dutch daredevil, commonly nicknamed "The Iceman" for his ability to withstand extreme cold.[1]

Early life[edit]

Hof was born in Sittard, Limburg. He has six brothers and two sisters.[citation needed]


Hof holds 20 world records, including a world record for longest ice bath.[2] Wim describes his ability to withstand extreme cold temperatures as being able to "turn his own thermostat up" through breathing exercises.[citation needed]

2007: He climbed to 6.7 kilometres (22,000 ft) altitude at Mount Everest wearing nothing but shorts and shoes, but failed to reach the summit due to a recurring foot injury.[3][4]

2008: He broke his previous world record by staying immersed in ice for 1 hour, 13 minutes and 48 seconds at Guinness World Records 2008.[citation needed] The night before, he performed the feat on the Today Show.[citation needed]

2009: In February Hof reached the top of Mount Kilimanjaro in his shorts within two days.[5] Hof completed a full marathon (42.195 kilometres (26.219 mi)), above the arctic circle in Finland, in temperatures close to −20 °C (−4 °F). Dressed in nothing but shorts, Hof finished in 5 hours and 25 minutes. The challenge was filmed by Firecrackerfilms, who make productions for BBC, Channel 4 and National Geographic.[6]

2010: Hof again broke the ice endurance record by standing fully immersed in ice for 1 hour and 44 minutes in Tokyo, Japan.[7]

2011: Hof broke the ice endurance record twice, in Inzell in February and in New York City in November. The Guinness World Record is now set for 1 hour and 52 minutes and 42 seconds by Hof.[8] In September, Hof also ran a full marathon in the Namib Desert without water. The run was performed under the supervision of Dr. Thijs Eijsvogels.[9]

Personal life[edit]

Hof has five children: four from a prior marriage, and a son (born in 2003) with his current wife.[10]

Fact or Faked[edit]

On 28 January 2012, an episode of the US television program Fact or Faked: Paranormal Files, featuring Hof, was broadcast. Hof was tested against a member of the team named Austin, both sitting in a tank full of ice. Austin sat in the tank for about 20 minutes. When he got out of the water, the other two team members used a heat camera to reveal that his surface body temperature was at about four degrees Celsius. Hof's core body temperature stayed the same for the entire twenty minutes, as did his heart rate. He managed to stay submerged for over ninety minutes.[11]


In 2016, the Wim Hof Method was blamed for the deaths of four men who drowned when practising this breathing exercise.[12] Hof, however, had warned to practice his method in a safe environment, and not in the water.[12][13]
