If I knew nothing about this I would trust the research and information from people who do it on the regular as opposed to some people on reddit who tried it a couple times.
Re-reading the TMO page on this, it seems to only call for a short breath-holding period, not 3 - 4 minutes (permanent brain damage starts at 4 - 5 minutes) as many in the Wim Hof groups do, as if it’s some kind of breath holding contest. I’m personally leery of extreme breath holding (which you can easily do after hyperventilating) and that is probably what causes people the most problems. I’m going to look into it some more.
