Pricing: €80–130 single session, €700–1,100 for the standard 10-session course. French centers occasionally pair IHHT with altitude-simulation training for Alpine endurance athletes — a useful overlap that doesn't exist in flatland markets.
The research base (Burtscher 2014, Schega 2013) supports cardiovascular adaptation effects similar to mild altitude exposure. Anti-aging and mitochondrial-biogenesis claims that show up in some French marketing exceed what the human peer-reviewed literature currently supports. Pick operators who can describe their specific protocol, what they monitor, and what realistic outcomes look like.
