1.      Increases oxygen availability and cellular energy

HBOT delivers 94-100% oxygen at higher pressures, saturating the blood plasma with oxygen far beyond normal levels.  This extra oxygen enhances mitochondrial function, improving ATP production and overall cellular efficiency.  Better energy production supports the repair and maintenance of tissues, slowing cellular decline with age.

2.      Stimulates stem cell release and tissue regeneration

Repeated HBOT mobilises stem cells from bone marrow into circulation.  These stem cells help replace damaged or senescent cells, aiding regeneration of skin, muscle, blood vessels, and even brain tissue.

3.      Reduces oxidative stress and inflammation

Although oxygen can generate reactive oxygen species (ROS) HBOT at controlled doses triggers the body’s antioxidant defence mechanisms.  It upregulates enzymes like superoxide dismutase (SOD) and catalase, leading to reduced chronic inflammation which is a major drive of ageing.

4.      Supports DNA repair and telomere length

A landmark 2020 Israeli study found HBOT increased telomere length my up to 38% and reduced senescent cells by up to 37% in healthy older adults.  Telomeres protect chromosomes from damage, longer telomeres are associated with slower biological ageing.

5.      Improves vascular and brain health

HBOT enhances angiogenesis (new blood vessel growth) and improves cerebral blood flow.  Better circulation supports heart, brain, and organ function, reducing risk of age-related decline and neurodegeneration.

6.      Boosts cognitive and physical vitality

By increasing oxygen delivery to the brain, HBOT improves memory, focus, and reaction time.  It also speeds up muscle recovery and reduces fatigue, helping maintain mobility and mental clarity as ageing continues.
