What if oxygen could do more than sustain life — what if it could heal it? Hyperbaric Oxygen Therapy (HBOT) is emerging as one of the most versatile tools in modern medicine, supporting recovery from injuries, enhancing brain health, and even extending longevity. In a recent episode of the me&my health up podcast, host Anthony Hartcher sat down with Nicole Garrett, CHT, founder of Under Pressure Hyperbarics in Beverly Hills, to explore the remarkable science and real-world impact of HBOT.
Nicole’s journey from commercial diving and dive medicine to opening hundreds of hospital-based hyperbaric clinics — and now her own center — highlights both the evolution and promise of this therapy. From treating decompression sickness to reversing radiation damage, HBOT is proving to be a powerful ally in healing and prevention.

At its core, HBOT involves breathing pure oxygen in a pressurised chamber. This process floods the body with oxygen, stimulating cellular repair, reducing inflammation, and promoting angiogenesis — the regrowth of small blood vessels. Unlike localised treatments, HBOT benefits the entire body, delivering oxygen where it’s needed most.
Nicole explains that HBOT is the only therapy in medicine proven to regrow new blood vessels. This makes it invaluable for post-surgery recovery, diabetic wounds, radiation injuries, and infections. Patients often experience unexpected benefits, such as improved sleep, energy, and even reduced reliance on arthritis medications.
One of the most exciting applications of HBOT lies in brain health. Nicole shares the story of a patient who arrived in a wheelchair, struggling with a non-healing wound and dementia-like symptoms. After a series of treatments, she not only healed physically but regained mobility, pushed her walker aside, and rang the clinic’s celebration bell with joy. Her family was astounded as her cognitive symptoms dissolved.
This story illustrates HBOT’s potential in addressing dementia, Alzheimer’s, and chronic traumatic encephalopathy (CTE). By restoring oxygen supply to damaged areas of the brain, HBOT supports neuroplasticity and helps reverse the effects of micro-strokes and trauma.
Athletes are increasingly turning to HBOT for faster recovery and performance gains. By reducing inflammation and accelerating muscle repair, HBOT allows athletes to train harder and recover quicker. Nicole notes that boxers use HBOT to help prevent long-term brain damage, while others balance hypobaric training with hyperbaric sessions to optimise oxygen availability and healing.
HBOT isn’t just about recovery — it’s about prevention and longevity. A landmark 2020 study revealed that a series of 60 treatments could add up to 25 years of life back onto telomeres, the protective caps of DNA that shorten with age. This finding has attracted biohackers and wellness enthusiasts eager to explore HBOT’s anti-aging potential.
Nicole also highlights surprising cases of vision restoration. Patients previously reliant on eye injections for high pressure have reported regaining vision, with eye exams confirming improvements once thought impossible. These emerging fields underscore HBOT’s expanding role in medicine.
Hyperbaric Oxygen Therapy is more than a treatment — it’s a catalyst for healing, recovery, and transformation. From reversing radiation damage to dissolving dementia symptoms, HBOT is proving to be a powerful, non-invasive therapy that enhances quality of life.
Nicole Garrett’s expertise and passion for advancing hyperbaric medicine remind us that oxygen, when harnessed correctly, can unlock extraordinary potential. Whether you’re an athlete, a patient recovering from surgery, or someone exploring longevity, HBOT offers a path to renewed vitality.
