Two decades of studying what we breathe

Evidence first

For more than twenty years we have studied the effects of elevated carbon dioxide levels on the human body. This website provides evidence-based information on CO₂ and other airborne contaminants — explaining which air pollutants may pose health risks, and how their negative effects can be reduced or, in some cases, minimised altogether.

That research informs both sides of our work: protective shelters that keep contaminated air out, and hypoxia-based training that puts controlled low-oxygen air to work for health and performance.
