IHHT Cell Training

A 50-minute mask-based session alternating between low-oxygen (hypoxia) and high-oxygen (hyperoxia) breathing intervals to stimulate mitochondrial adaptation. Intermittent hypoxia-hyperoxia training (IHHT) is designed to challenge cellular energy systems in a controlled way, encouraging the body to replace less efficient mitochondria with healthier ones. The session is passive — clients recline comfortably while the system cycles through oxygen levels automatically.

Cryodukt's IHHT Cell Training programme uses intermittent hypoxia-hyperoxia training — a mask-based breathing protocol that alternates between periods of reduced oxygen (simulating high-altitude conditions) and periods of enriched oxygen. Each session lasts approximately 50 minutes, during which the client reclines comfortably and breathes through a mask connected to the IHHT device. The underlying principle is mitochondrial conditioning. Mitochondria are the primary energy-producing structures within cells, and their efficiency directly influences overall vitality, cognitive function, and physical performance. During the hypoxic phase, oxygen levels drop to simulate conditions at altitude — typically equivalent to 2,000 to 6,500 metres. This controlled oxygen deficit creates a mild stress signal that may trigger the body's natural quality-control mechanism for mitochondria, a process sometimes called mitophagy. Less efficient or damaged mitochondria may be identified and recycled, while healthier mitochondria are stimulated to replicate. During the hyperoxic phase, oxygen concentration rises above normal levels, flooding cells with oxygen and supporting recovery from the brief hypoxic interval. The alternating pattern — typically 3 to 5 minutes of hypoxia followed by 1 to 3 minutes of hyperoxia, repeated across the session — is designed to create a training effect on the mitochondria without causing sustained oxygen deprivation. The IHHT device monitors blood oxygen saturation throughout the session and adjusts the protocol in real time. If saturation drops below a safe threshold, the system automatically switches to the hyperoxic phase. This makes the treatment suitable for a wide range of fitness levels, from athletes seeking a competitive edge to older adults interested in supporting cellular vitality. Research into intermittent hypoxia training is still evolving, but early studies suggest it may support improvements in cardiovascular function, metabolic regulation, cognitive performance, and exercise tolerance. Some practitioners use IHHT as part of a protocol for managing fatigue, supporting weight management, or preparing for high-altitude travel. Cryodukt recommends a series of 15 to 25 sessions for meaningful adaptation, with two to three sessions per week as a typical frequency. The 15-session pack at CHF 1,350 (CHF 90 per session) balances commitment with meaningful savings.
