Key peer-reviewed studies supporting HBOT applications across clinical specialties and longevity medicine, with evidence levels and direct links to source publications.
Evidence Levels:
Hadanny A, Daniel-Kotovsky M, Suzin G, et al. · Aging (Albany NY) · 2020
Key Finding
60 HBOT sessions increased PBMC telomere length by >20% and significantly reduced senescent T-cells — first human evidence of non-pharmacological telomere lengthening.
Amir H, Malka DK, Gil S, et al. · Aging (Albany NY) · 2020
Key Finding
HBOT induced significant cognitive enhancements in healthy aging adults via mechanisms involving regional changes in cerebral blood flow.
Fu Q, Duan R, Sun Y, Li Q. · Redox Biology · 2022
Key Finding
First comprehensive overview of HBOT in aging and geriatric research. Therapeutic targets of HBOT overlap considerably with hallmarks of aging.
Hadanny A, Sasson E, Copel L, et al. · BMC Geriatrics · 2024
Key Finding
HBOT improved maximal physical performance and cardiac perfusion in sedentary older adults, including enhanced VO2 max and cardiovascular function.
Singh AK, Jha DK, Jena A, et al. · European Journal of Gastroenterology & Hepatology · 2021
Key Finding
HBOT achieved response rates exceeding 80% in both ulcerative colitis and Crohn's disease, with significant mucosal healing demonstrated.
Wolf G, Cifu D, Baugh L, et al. · Neurology · 2012
Key Finding
B-level evidence supporting HBOT for mild TBI and post-concussion syndrome, showing improvements in neurocognitive deficits and post-concussion symptoms.
Doenyas-Barak K, Catalogna M, Kutz I, et al. · PLoS One · 2022
Key Finding
HBOT significantly improved PTSD checklist scores and demonstrated measurable improvements in brain microstructure on advanced MRI in treatment-resistant PTSD veterans.
Huang X, Wang R, Zhang Z, et al. · Frontiers in Physiology · 2021
Key Finding
First meta-analysis on HBOT for exercise performance and recovery. Consistent benefits in muscle recovery, reduced inflammation, and enhanced endurance capacity.
The HBOT evidence base spans over 258 peer-reviewed publications, including multiple Level I randomized controlled trials and systematic reviews. The strongest evidence supports wound healing, decompression sickness, and carbon monoxide poisoning, while emerging Level I evidence now supports longevity and cognitive enhancement applications.
