Peer-Reviewed Research
Superhuman Chambers has compiled 20 of the most cited peer-reviewed HBOT studies, spanning four decades of clinical research. Published in journals including the New England Journal of Medicine, the Cochrane Database of Systematic Reviews, and Scientific Reports, they represent the scientific foundation behind hyperbaric oxygen therapy.

From wound healing to longevity.
Four decades of clinical evidence.
The evidence base
Hyperbaric oxygen therapy (HBOT) is a medical treatment that involves breathing pure oxygen inside a pressurized chamber, typically at 1.5 to 2.0 atmospheres absolute (ATA). The increased pressure allows the lungs to absorb significantly more oxygen than at normal air pressure, which dissolves into blood plasma and reaches tissues throughout the body.
Across these 20 studies, the clinical evidence for HBOT converges on several consistent findings. In wound healing, randomized controlled trials show that HBOT nearly doubles healing rates for chronic diabetic foot ulcers compared to standard care. A landmark 2006 study demonstrated the biological mechanism: a single HBOT session doubles the number of circulating stem cells in the bloodstream. In neurological research, HBOT has shown the ability to induce neuroplasticity in post-stroke patients even years after the initial event, and a landmark NEJM trial established HBOT as the standard of care for carbon monoxide poisoning. Recent studies from Tel Aviv University found that HBOT can lengthen telomeres by 20-38% and clear senescent cells by 11-37% in healthy older adults. The evidence also extends to sports recovery, radiation injury repair, and chronic conditions including fibromyalgia and long COVID.
The majority of the studies listed below are randomized controlled trials (RCTs) or Cochrane systematic reviews, the two highest tiers of clinical evidence.

HBOT's longest-established clinical use. These trials demonstrate its role in chronic wound resolution and the biological mechanisms behind it.
Randomized controlled trial of 94 diabetic patients. HBOT group achieved complete ulcer healing in 52% of cases vs. 29% in the control group at one-year follow-up.
View on PubMedDouble-blind RCT showing significantly improved wound healing and reduced amputation rates in diabetic patients receiving HBOT compared to sham treatment.
View on PubMedCochrane systematic review of 12 trials. Found that HBOT significantly improves ulcer healing rates in diabetic foot ulcers at six weeks and at one year.

Recent studies from Tel Aviv University's Sagol Center have opened a new frontier for HBOT in aging research, with measurable changes at the cellular level.
A prospective trial in 35 healthy adults over 64. HBOT significantly lengthened telomeres (20-38%) and cleared senescent cells (11-37%), two key hallmarks of biological aging.

HBOT's ability to promote neuroplasticity and reduce neuroinflammation has been studied in stroke, TBI, carbon monoxide poisoning, and PTSD.
Prospective RCT in 74 post-stroke patients (6-36 months post-event). HBOT led to significant neurological improvements and increased brain activity on SPECT imaging, even years after the stroke.
View on PubMedRCT in 56 mTBI patients with persistent post-concussion symptoms. The HBOT group showed significant improvements in cognitive function, quality of life, and brain metabolic activity.
View on PubMedLandmark NEJM double-blind RCT. HBOT reduced cognitive sequelae at 6 weeks and 12 months following acute CO poisoning, establishing it as standard of care for this indication.
View on PubMedProspective trial in combat veterans with treatment-resistant PTSD. HBOT produced significant reductions in PTSD symptoms and improvements in brain function on MRI.

HBOT is used to treat radiation tissue damage and has been studied for safety alongside cancer treatment. These papers address both the therapeutic applications and the safety profile.
Comprehensive review addressing the safety question of HBOT in cancer patients. Concluded there is no evidence that HBOT promotes cancer growth, and that it may enhance the effects of certain cancer treatments.

Emerging research explores HBOT for conditions characterized by chronic pain, fatigue, and inflammation, including fibromyalgia, chronic fatigue syndrome, and long COVID.
Prospective RCT in 60 fibromyalgia patients. HBOT led to significant reductions in pain, fatigue, and tender point counts, with corresponding improvements in brain SPECT imaging.
View on PubMedClinical study showing significant improvements in fatigue severity, cognitive function, and quality of life scores in chronic fatigue syndrome patients treated with HBOT.
View on PubMedRCT in 73 long COVID patients with cognitive symptoms persisting 3+ months. HBOT significantly improved attention, executive function, energy, and psychiatric symptoms compared to sham.
