Strengthen your body and be able to prevent disease

ICE Man Wim Hof

Wim Hof became known for his spectacular records: he ran half a marathon in Lapland at -30oC, frequently sat in a pool of ice for over ninety minutes, and swam hundreds of metres under the ice, from one hole to the next. It got him a long list of entries in the Guinness Book of Records. But Wim Hof wanted more. He wanted recognition. "I am now a circus act, but I want to be a scientist: my body is my lab", said Wim, even in 2008.

Scientific literature said it was impossible, but Dutch Radboudumc researchers have now proven that it is possible voluntarily to influence both the autonomic nervous system and the immune system. In 2011 the same researchers monitored the response of Iceman Wim Hof's body to an endotoxin injection as he performed the techniques he had developed himself. It turned out that he produced half the amount of inflammatory proteins healthy volunteers did who did not master his method. Moreover, he hardly showed any influenza symptoms. It seemed that he could suppress his immune response through the autonomic nervous system. But since one finding in one individual does not constitute scientific evidence, the scientists decided to do a follow-up study. For that reason, in 2013, studies were performed on a group of young, healthy, male volunteers: and, indeed, it turns out they are able to influence both the autonomic nervous system and the immune system.
