Hyperbaric oxygen therapy anti-aging claims start with a few studies.
Most hyperbaric oxygen therapy anti-aging claims trace back to a small number of studies from one research group in Israel. They looked at markers in blood cells, heart and fitness measures, and thinking skills in healthy adults aged 64 and older.
HBOT does not reverse aging, and it is not FDA-cleared for aging or longevity. Researchers are studying whether it may influence some biological markers. That is a worthwhile question, and it is also a long way from a longer or healthier life.
What the telomere study measured.
Telomeres are protective caps on the ends of chromosomes. They tend to shorten as cells divide, so researchers use them as one marker of cellular aging. In a 2020 study, 35 healthy adults aged 64 and older completed 60 HBOT sessions. The researchers reported longer telomeres in several types of immune cells and fewer senescent, or worn out, immune cells.
The study had no control group, so there was nothing to compare the changes against. It measured cells from blood samples, not the whole body. And it did not follow people long enough to show whether any change lasted or made a difference to health.
Surrogate markers are not the same as outcomes.
A surrogate marker is something measured in a lab or scan that may relate to a real outcome. Telomere length, blood flow on MRI and oxygen uptake during exercise are all surrogate markers. They can move without changing how long or how well someone lives.
A 2024 trial from the same group reported better fitness and heart blood flow measures in older adults after HBOT. It too compared HBOT with no intervention rather than a sham, and participants knew their group. These studies raise questions worth testing. They do not prove that HBOT slows aging.
What still matters most for healthy aging.
Regular movement, strength training, sleep, blood pressure control, not smoking, and staying socially connected have far stronger evidence behind them than any chamber. If HBOT interests you, think of it as a wellness experience that may support how you feel, not a replacement for those basics or for your regular checkups.
Some people pair HBOT with red light therapy for skin, which is also a wellness service at Suntree. Our wellness and longevity page and cellular function page cover related research.
Plan it with clear eyes.
The studies above used 60 sessions at 2.0 ATA, 90 minutes each, over about three months. A standard session at Suntree is 60 minutes in a chamber rated for up to 2.0 ATA, and the team confirms pressure and protocol for you. Compare session and membership pricing before committing to a long series.
Older adults often take several medications or have heart and lung history worth reviewing. Ear barotrauma, sinus congestion, a history of collapsed lung, and claustrophobia are all part of the conversation. Talk with your physician, then with the team in Rockledge.
