He said: “Combined with the Wim Hof Method, the quieting of the mind as well gives you a slight feeling of euphoria. The one works better with the other.”
Despite his embrace of the technique, Davies, who used to be a fitness instructor, said he was removed from the Wim Hof Method group on Facebook for raising concerns about the intensity of the breathing technique.
He suggested that breathing through your mouth, which the method recommends as part of the technique “is bad advice”.
He said: “You're breathing in cold air, you're not filtering the air, it can cause long term health issues. The Wim Hof Method is not perfect. However, it's still more beneficial than not.”
