That was scary to watch. I've had a similar experience [3] performing the Wim Hof Method [1] under medical supervision [2]. For 10 to 20 seconds they were asking me the question of: "Mettamage, what is your name?!" And it took me 10 to 20 seconds to register the question. Moreover, I wasn't the only one and also not the extreme one. My friend (whom I supervised myself) was out for 30 seconds and there was one person during the experiment who seemed to be out for 2 to 3 minutes. The doctors were rushing to get an oxygen mask but then he 'woke up' again and was normal. I think in the case of the Wim Hof Method training phase what ultimately happens is that you instinctively breath again at some point and therefore get normal oxygen again (after not having it for 2 to 3 minutes after breathing all your oxygen out). [1] There's a training phase in the Wim Hof Method where you can have a severe lack of oxygen. When you use the actual Wim Hof Method in order to battle the cold you won't experience it. The training phase is designed for you to understand more intuitively how to do it. [2] I was a test subject for this scientific experiment: http://www.innerfire.nl/files/pnas.pdf http://www.innerfire.nl/files/pnas.pdf -- non-paywalled PNAS publication -- PNAS link: https://www.pnas.org/content/111/20/7379 https://www.pnas.org/content/111/20/7379 [3] See the scientific explanation behind it here: https://news.ycombinator.com/item?id=18911674#18919660 https://news.ycombinator.com/item?id=18911674#18919660 -- while oxygen levels stay at 99%, the availability is a lot less. It does mention that the blackout itself is caused by hypoxia.

  It's a bit off-topic but what is the conclusion then, is Wim Hof method safe to do long-term and in a safe environment without medical supervision?
