Hydrogen, which exhibits anti-oxidative and anti-inflammation effects, was proved to be relatively safe for inhalation in diving.9,10 The concentration of hydrogen used in our study is quite lower (∼2.4%). Due to its small molecular weight, hydrogen can easily penetrate bio-membranes and diffuse into cytosol and organelles, and the tissue compatibility of hydrogen is stronger than many other oxidant scavengers. In this study, we demonstrated that a single inhalation of 45 min hydrogen gas could reduce airway inflammatory mediators in patients with asthma or COPD.
