Pricing reflects the niche positioning: $80–150 per session, $700–1,400 for the standard 10-session course. Most US protocols mirror the German 40-minute, 5–7 cycle structure, with SpO₂ monitoring throughout. A few US centers have adapted IHHT for altitude-simulation training (alternative to a Hypoxico tent) for endurance athletes preparing for high-altitude races.
Research context: the cardiovascular adaptation literature is small but consistent (Burtscher 2014, Schega 2013). The longevity and mitochondrial-biogenesis claims that show up in some US marketing exceed what the peer-reviewed human research currently supports. If you're considering IHHT, look for operators who can describe their specific protocol, what they monitor and what realistic outcomes look like — and skip anyone selling it as standalone anti-aging therapy.
