The claims by and around Wim Hof are often pretty absurd. I wouldn't go so far as to call him a charlatan, but there's a sliding scale and he's more to one side than the other.

I'm sure there's _some_ benefit to breathing techniques, but I wouldn't be surprised if they were at about the level of 'general exercise and wellbeing'.

Have you actually looked into it? The stuff he's doing is quite scientifically controlled/verified. He's controlling his autonomic nervous system in interesting ways, and his advanced students are doing the same thing.
