Hitherto, both the autonomic nervous system and innate immune system were regarded as systems that cannot be voluntarily influenced. The present study demonstrates that, through practicing techniques learned in a short-term training program, the sympathetic nervous system and immune system can indeed be voluntarily influenced.

The Start of Scientific Research 

What Wim is capable of was long viewed as scientifically impossible. In 2007 the first scientific analysis was done at Feinstein Institute in New York. In 2011, the University Medical Center St. Radboud in Nijmegen really got the ball rolling. After running several tests they couldn’t but admit that Wim and others are able to voluntarily influence the Autonomic Nervous System. Something which up until then was thought impossible, through the wim hof method. This groundbreaking finding, published in PNAS and Nature, established credibility and bred curiosity among academia. Increasingly, researchers across a wide range of disciplines have since taken an interest, and various promising studies are currently underway.
