Can you warm yourself with your mind?
> "results must be interpreted with caution given the low subject number and the fact that both participants practised the g-Tummo like breathing technique." [0]<p>Wim Hof not only claims that his method will keep one warm, but also a lot of other health benefits. Very few of these have any scientific backing. Hyperventilation's effects on inflammatory responses are well known.<p>His claims regarding arthritis, MS or even Parkinson's are not only spurious at best to be kind in wording. I would personally call them bullshit. There is just no scientific evidence at all for these claims.<p>Ensuring through deep breath that your chest muscles are moving and warming and by that warming your blood is nice - but not more. There are no studies scientifically researching the method with multiple subjects. Only studies that look at him (and his twin).<p>So we have "studies" with n=2 and massive claims from him. While he sells his books/seminars/method.<p>People have died attempting the Wim Hof Method (one example [1]).<p>To me - this person is good at PR. Knows how to sell these days. And how to be a personal brand. I have to give credit for that.<p>[0]: <a href="https://www.tandfonline.com/doi/full/10.1080/23328940.2017.1329001" rel="nofollow">https://www.tandfonline.com/doi/full/10.1080/23328940.2017.1...</a>
