Wim Hof Breathing
Wim Hof breathing uses cyclic hyperventilation and breath holds for stress and cold prep—practice seated safely; evidence beyond short-term arousal is limited.
Wim Hof breathing is a cyclic hyperventilation-and-hold protocol popularized for stress tolerance and cold exposure pairing—never practiced in water or while driving. Rounds of thirty to forty deep breaths followed by breath holds create tingling and altered CO2 sensitivity; evidence for long-term health gains is mixed.
Stop if dizzy or panicked.
