James Hamblin at The Atlantic:
On the stage stood a Dutch man in black shorts and a synthetic blue shirt. His grayish hair flopped as he paced. He looked somehow robust despite an absence of prominent musculature and a sort of convex abdomen. This was Wim Hof.
“Depression, fear, pain, anxiety—you name it,” Hof’s voice boomed through the speakers. “We are able to get into any cell and change the chemistry. We are able to get into the DNA.”
Hof claims that people can address, prevent, and treat most any malady by focusing the mind to control the metabolic processes in their cells. For example, we can will our bodies to heat up in cold situations. He told the audience “we can beat cancer” by shutting down malignant cells. “I challenge any university in the world to test this out,” he roared.
For a four-hour seminar in The Wim Hof Method, attendees paid around $200. The ticket offered an opportunity to hear Hof speak and to perform his famous breathing exercises, and then to take a brief dip in an inflatable pool of ice water.
