Running half-marathons barefoot in the snow. Climbing mountains while wearing only shorts. Standing in a cylinder filled with 700 kilograms of ice cubes.
Self-proclaimed “Iceman” Wim Hof, claims that he can do all of these things by influencing his autonomic nervous system (ANS) through concentration and meditation. The “Wim Hof Method,” is an intensive meditative practice that includes focused concentration, cold water therapy, and breathing techniques. Until recently, the idea that anyone could influence their autonomic nervous system was thought impossible given its assumed “involuntary” nature. The ANS is the system that controls all of our internal organs and regulates body functions like digestion, blood flow, and pupil dilation.
Our brains also uses the ANS to communicate to our immune system, which might explain another of the Iceman’s recent feats: suppressing his immune response after being dosed with an endotoxin (a bacteria), which in most people leads to flu-like symptoms and high levels of inflammation in the body. When researchers looked at the Iceman’s inflammatory markers after being exposed, they discovered the markers were low, and his immune response was 50% lower than other healthy volunteers. Basically, he showed very few signs of infection.
Hof is definitely a statistical outlier, though one recent study followed…
