https://en.wikipedia.org/wiki/Wim_Hof Wim Hof ([ʋɪm ɦɔf]; born 20 April 1959), also known as The Iceman, is a Dutch motivational speaker and extreme athlete noted for his ability to withstand very low temperatures.[1] He has set Guinness World Records for swimming under ice and prolonged full-body contact with ice, and previously held the record for a barefoot half marathon on ice and snow. He attributes these feats to his Wim Hof Method (WHM), a combination of frequent cold exposure, breathing techniques, yoga and meditation. Hof has been the subject of several medical assessments and a book written by investigative journalist Scott Carney.[2] Wim Hof Wim Hof.jpg Hof immersed in an ice bath, 2007 Born 20 April 1959 (age 63) Sittard, Limburg, Netherlands Occupation Extreme athlete Children 6 Website https://www.wimhofmethod.com/
