Hof is a dangerous fraud. His identical twin brother doesn't follow these practices at all and has the exact same capabilities. They are just genetic outliers. > Professor Mike Tipton of the University of Portsmouth, who has been studying the effects of cold water on the body for 40 years, found that young and healthy individuals had a 1 to 3 per cent chance of cardiac arrhythmia when in cold water. > But when they were asked to hold their breath beforehand, that figure rose to 63 per cent. “It’s an incredible way of reproducing cardiac arrhythmias in otherwise fit and healthy individuals,” he said. This man has blood on his hands and you're just lucky it isn't yours.

This is nonsense, your information is not correct. Yes, I have read the study[1] where they found his brother didn't have any measurable physiological differences... the thing is anybody can do this stuff, not just him and his brother- me and several friends that are into it also can. He may have a BAT mutation that makes it easier to do longer, but focusing on that is missing the point. The adaptations are psychological, it is a type of meditation/yoga- his methods are based on ancient Tibetan Vajrayana methods like Tummo, that he has innovated on somewhat. What both cold water immersion, and his breathing method do is cause a physiological panic- from either the cold, or from manipulating CO2 levels. This forms the basis for a type of meditation where you learn to calm this response. That can be life changing, because it allows you to control stress and anxiety, and stay clear and calm when doing difficult things in other areas of life. This isn't explicitly explained by Wim, because it requires an attitude or feeling rather than an explanation, which happens automatically with practice. If you know about Vajrayana, this makes a bit more sense. I think it is pretty obvious that the panic itself is dangerous and likely the major cause of e.g. cardiac events, and training your mind and body to not panic does make it safer- that was the point of my original post you replied to. Wim is a skilled yoga practictioner and instructor, that is all he is. He is not a scientist, and (unfortunately) likes to make scientific claims that aren't exactly fraudulent, just incoherent- he is excited about but doesn't understand what people found when studying him, is trying to talk about it, but is saying incorrect things. As a scientist I wish he would not do that- the value of his methods is obvious from experiencing them- they have been life changing for my mental health, I don't need a scientific explanation that they have some provable physical effect. The people dying from doing this have all been doing it incorrectly- explicitly doing things he tells people not to do: they are doing the breathing and cold water at the same time, blacking out from low oxygen, and then drowning. Wim doesn't do that, or tell anyone to do it. I am also a freediver, and this is basic freediving 101 safety, to not do any hyperventilation breathing exercises before diving. Ultimately, like all human activities, there is some danger in doing this method but saying he has "blood on his hands" or is a fraud is absurd and hyperbolic. There is nothing really especially dangerous about this compared to other difficult yoga techniques, which also have both risks and benefits.

Blood on his hands is a little strong. You don’t think the ethics might be little more subtle?

  No if I thought that I would have said something else. He's lying and knows it and people have died because they believed him and he continues to lie. I said what I said and I stand by it.

    What is he lying about? I’ve read his book, taken his course, and practiced his method daily for many years. He is quite straightforward that it has risks, and extensively discusses safety and things to mitigate those risks. He also warns people against repeating his extreme stunts- the most dangerous thing in his classes is a 2-3 minute ice cold bath in a bath tub at home- something also regularly done by athletes in most sports. The breathing exercises are never done in or near water. People can teach things that are risky to consenting adults they understand risks- driving, freediving, hang gliding, and having a sedentary desk job are all far riskier activities than WHM that I also choose to do…. They could all kill me but I sure won’t blame the instructors I learned from.
