Wim Hof (born 20 April 1959) is a Dutch daredevil, commonly nicknamed "The Iceman" for his ability to withstand extreme cold, which he attributes to exposure to cold, meditation and breathing techniques (similar to the Tibetan technique Tummo).

Wim Hof has set out to spread the potential health benefits of his breathing techniques, working closely with scientists around the world to prove that his techniques work.

A recent study published in the Proceedings of the National Academy of Sciences of the United States of America claims that by consciously hyperventilating, Wim can increase his heart rate, adrenaline levels and blood alkalinity. Wim is also believed to possess much higher levels of brown adipose tissue which aids in cold resistance.

Hof was born in Sittard, Limburg, Netherlands as one of nine children. When he was 17 he was drawn to cold water.

Hof holds 26 world records, including a world record for longest ice bath. Wim describes his ability to withstand extreme cold temperatures as being able to "turn his own thermostat up" through breathing exercises.

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.

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. The night before, he performed the feat on the Today Show.

2009: In February Hof reached the top of Mount Kilimanjaro in his shorts within two days. 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.
