Hyperbaric Oxygen Therapy

A 60-to-90-minute hyperbaric oxygen therapy session at two atmospheres of pressure breathing 100 percent oxygen. The elevated pressure dissolves significantly more oxygen into the blood plasma than is possible at normal atmospheric pressure, delivering oxygen to tissues at concentrations far beyond what red blood cells alone can carry. This hyperoxygenated environment may support tissue repair, reduce inflammation, and enhance cognitive function.

Hyperbaric oxygen therapy (HBOT) at AYUN involves breathing 100 percent oxygen inside a pressurised chamber at two atmospheres absolute (2 ATA) for 60 to 90 minutes. At this pressure, oxygen dissolves directly into blood plasma at concentrations roughly 10 to 15 times higher than under normal atmospheric conditions, allowing it to reach tissues that may be underserved by standard circulation. The elevated tissue oxygen levels trigger several physiological responses. Angiogenesis — the formation of new blood vessels — may be stimulated in areas of low oxygen supply. Stem cell mobilisation from bone marrow increases, potentially supporting tissue repair across the body. The immune system benefits from enhanced white blood cell function in oxygen-rich environments. Inflammation may be modulated through effects on cytokine signalling and oxidative stress pathways. Research has explored HBOT across a wide range of applications. In sports medicine, it is used to support recovery from soft tissue injuries, fractures, and post-surgical healing. Neurological research has investigated its effects on traumatic brain injury recovery, cognitive performance, and neuroprotection. Longevity-focused studies have examined its influence on telomere length and senescent cell clearance, though this research remains in early stages. During the session at AYUN, clients lie comfortably inside the chamber. The pressurisation phase takes approximately 10 minutes, during which mild ear pressure changes may occur — similar to the sensation during aircraft descent. The main treatment phase at full pressure lasts 60 to 90 minutes, during which clients can rest, read, or use a mobile device. Depressurisation takes another 10 minutes. Single sessions are priced at CHF 260. A 10-session pack at CHF 2,340 provides a 10 percent saving per session, while a 20-session pack at CHF 4,160 offers a 15 percent reduction. AYUN recommends discussing session frequency with the medical team, as optimal protocols vary depending on individual goals — recovery-focused clients may benefit from daily sessions over a short intensive course, while maintenance clients typically attend once or twice per week. HBOT is one of AYUN's premium modalities and pairs effectively with cryotherapy for a recovery-focused protocol combining anti-inflammatory cold exposure with tissue-repairing hyperoxygenation.
