I've met Wim Hof [1], his mind is not precise when it comes to scientific things. In that sense I'd recommend a huge caution to what he claims about the health benefits of his method. But hey, at least he's utilizing the placebo effect, and trust me, when you use his actual method for things it actually works for, you still want that placebo effect added to it as well ;-) Luckily though, he does recognize that to some extent. Because of that, he sometimes does research with actual scientists, and I have talked to a few of them. IMO those claims you can trust, or at least trust as much as any scientific claim.
