IHHT Altitude Training

A 40-to-60-minute intermittent hypoxic-hyperoxic training (IHHT) session that alternates between low-oxygen and high-oxygen breathing phases through a comfortable mask. This passive protocol targets mitochondrial quality by stimulating the selective removal of damaged mitochondria and the production of new, efficient ones. Pulse oximetry monitoring ensures safe oxygen saturation levels throughout the session.

IHHT (Intermittent Hypoxic-Hyperoxic Therapy) at AYUN delivers alternating phases of reduced-oxygen air — simulating altitudes of 2,000 to 6,500 metres — and oxygen-enriched air through a breathing mask while you recline comfortably. Each session lasts 40 to 60 minutes and is continuously monitored with pulse oximetry to ensure oxygen saturation remains within safe parameters. The mechanism targets mitochondrial quality control at the cellular level. During hypoxic phases, cells experience mild oxygen deprivation that acts as a selective pressure. Mitochondria that are damaged, inefficient, or producing excessive reactive oxygen species are identified and marked for removal through a natural quality-control process called mitophagy. During subsequent hyperoxic phases, the body receives a signal to produce new, healthy mitochondria — a process called mitochondrial biogenesis. Over a course of sessions, this selective pressure may improve the overall quality and efficiency of cellular energy production. Research has explored IHHT for effects on cardiovascular health, including improved heart rate variability and blood pressure regulation. Studies also suggest potential benefits for metabolic function — enhanced fat oxidation, improved insulin sensitivity — as well as cognitive performance, sleep quality, and stress resilience. The therapy is particularly relevant for individuals who cannot exercise intensely due to injury, age, or medical conditions but still want to access some of the cellular adaptations associated with physical training at altitude. No physical exertion is required during the session. Clients breathe normally through the mask while resting in a reclined position. The AYUN medical team reviews health history before the first session to calibrate the hypoxic intensity appropriately for each individual. Single sessions are priced at CHF 115, with 10-session packs at CHF 1,035 (10 percent saving) and 20-session packs at CHF 1,840 (20 percent saving). AYUN typically recommends a course of 10 to 15 sessions spaced two to three times per week for initial mitochondrial conditioning, followed by maintenance sessions once or twice monthly. IHHT pairs well with AYUN's other modalities. Combining altitude training with cryotherapy and red light therapy creates a multi-pathway approach to cellular resilience and recovery.
