not at all wim hof method is lifechanging. ive found that it has increased my fluid intelligence.
if you want the guru free non marketing version of this just look up how to do tuumo and pranayama.
i dont even do apnea really, the majority of benefit is in the breathing. doesnt even matter what technique just breathe more. think of getting oxygen like money, the more you breathe, the richer in consciousness and therefore intelligence you are.

any questions just ask
