According to Fincham et al. (2023), "The WHbM involves cyclic hyperventilation, incorporating periods of fast ventilation (usually 30-40 fast and deep breaths) followed by apnoea (whereby a participant alternates between the two) (Kopplin & Rosenthal, 2022). The WHbM also includes cold water exposure, muscle stretching and meditation, with the adoption of a ‘mindset,’ operationalised as intention setting – the combination of the two aims to increase general stress resilience. This technique is finding favour in scientific literature (i.e., Kox et al., 2014)."
