Can Hyperbaric Oxygen Therapy (HBOT) Anti-Aging or Delay Aging? Evidence, Risks, and Taiwan Status at a Glance
Hyperbaric oxygen therapy (HBOT) is a standard medical treatment involving breathing nearly pure oxygen in a pressurized chamber, used for specific indications such as carbon monoxide poisoning, decompression sickness, and non-healing wounds. However, in recent years, it has been promoted by anti-aging clinics with marketing terms like 'anti-aging, delay aging, restore youth'—these uses are unproven and not approved indications. The US FDA has warned against HBOT being marketed for unapproved uses (including anti-aging); a frequently cited 2020 Israeli study was small, lacked a control group, and had commercial interests linking researchers and clinics, so it cannot be considered evidence for anti-aging. Below is a neutral summary of its approved uses, anti-aging evidence, risks, and Taiwan status; anti-aging use is unproven, carries risks, requires physician evaluation, and is subject to TFDA and NHIA regulations. This page is for informational purposes, not medical advice.
What is hyperbaric oxygen therapy? What is it originally used for?
Hyperbaric oxygen therapy involves placing a person in a pressurized chamber and breathing near-pure oxygen at higher than atmospheric pressure, significantly increasing oxygen dissolved in the blood:
- It is a legitimate medical treatment, with about a dozen specific indications recognized by the Undersea and Hyperbaric Medical Society (UHMS)
- Common indications include: carbon monoxide poisoning, decompression sickness (diver's disease), gas embolism, gas gangrene and necrotizing soft tissue infections, non-healing wounds (e.g., diabetic foot), radiation tissue injury, crush injuries, sudden sensorineural hearing loss, etc.
- Key point: Anti-aging and slowing aging are not among these approved indications
Is there evidence for anti-aging or slowing aging?
For anti-aging in healthy individuals, the effects of hyperbaric oxygen are not proven:
- The US FDA has warned that hyperbaric oxygen is being marketed for unapproved and unproven uses (including Alzheimer's, autism, anti-aging, etc.), and these claims are not FDA-approved
- The mainstream view is that hyperbaric oxygen has not been proven to slow, stop, or reverse aging; even if some biomarkers change, that does not equate to living longer or being healthier
- The FDA also reminds that treating unproven uses as effective may delay proper treatment
Is the study on 'telomere lengthening' credible?
A 2020 Israeli study (Hachmo et al., Aging journal) is often cited, but should be viewed very conservatively:
- Small scale: about 35 healthy participants aged 64+, with even fewer actually analyzed, and no control group (no placebo)
- It examined surrogate markers (telomere length, senescent T cells), not proof of actual aging delay or lifespan extension; duration of effects unknown
- Researchers and affiliated clinics (Aviv/Shamir) have commercial interests. Overall, this is preliminary and requires independent replication; it cannot be taken as evidence for anti-aging efficacy
Risks and side effects
Even when used legitimately, hyperbaric oxygen therapy carries risks and requires medical evaluation and monitoring:
- Most common are ear or sinus barotrauma (causing middle ear discomfort or eardrum injury); temporary myopia (usually resolves within weeks) and claustrophobia/anxiety in confined spaces
- Oxygen toxicity can cause rare seizures (usually resolve after stopping oxygen), rare lung damage; pressurized pure oxygen environment also poses fire risk
- The FDA reiterated safety warnings in 2025—chambers have been used in non-medical wellness settings by non-medical personnel, leading to serious incidents; must be performed in qualified medical facilities under physician evaluation
Current situation in Taiwan and neutral perspective
In Taiwan, hyperbaric oxygen is a legitimate treatment provided in hospitals, with regulated uses and reimbursement:
- Health insurance covers specific indications (e.g., carbon monoxide poisoning, necrotizing soft tissue infection, gas gangrene, decompression sickness, radiation tissue injury, crush injury; some require prior review); chronic diabetic foot wounds, sudden sensorineural hearing loss are often self-paid.
- Using hyperbaric oxygen for 'anti-aging/slowing aging' is off-label (self-paid), constitutes a medical procedure requiring physician evaluation, and must comply with regulations of the Taiwan Food and Drug Administration and the National Health Insurance Administration.
- Claims such as 'reverse aging, restore youth, anti-aging' should be viewed conservatively—these are marketing terms by providers, not proven or approved effects. For related concerns, consult a qualified physician. This page provides neutral information, not medical advice.
FAQ
Can hyperbaric oxygen therapy anti-aging or delay aging?
Currently unproven and not an approved indication. HBOT is a standard treatment for specific indications such as carbon monoxide poisoning, decompression sickness, and non-healing wounds; anti-aging is not among approved indications. The US FDA has warned against HBOT being marketed for unapproved uses (including anti-aging), and the mainstream view is that it has not been proven to delay, stop, or reverse aging. This page provides neutral information, not medical advice.
Is it true that a study showed HBOT lengthens telomeres and reverses aging?
This should be viewed very conservatively. A frequently cited 2020 Israeli study (Hachmo et al.) was small (about 35 healthy older adults, even fewer analyzed), lacked a control group, examined surrogate markers like telomere length rather than actual aging delay or lifespan extension, and had commercial interests linking researchers and clinics. This is a preliminary result requiring independent replication and cannot be considered evidence of anti-aging efficacy.
What are the risks or side effects of hyperbaric oxygen therapy?
The most common are ear or sinus barotrauma, temporary myopia (usually resolving within weeks), and claustrophobia; oxygen toxicity may cause rare seizures and rare lung injury, and the pressurized pure oxygen environment poses a fire risk. The FDA warned in 2025 that recent non-medical wellness facilities have operated and caused serious accidents; HBOT should be performed in qualified medical facilities under physician evaluation.
Is hyperbaric oxygen therapy covered by health insurance in Taiwan?
It is covered for specific indications, such as carbon monoxide poisoning, necrotizing soft tissue infections, gas gangrene, decompression sickness, radiation tissue injury, crush injury, etc. (some require prior authorization); diabetic foot chronic wounds and sudden sensorineural hearing loss are often self-paid. Using HBOT for anti-aging is off-label (self-paid); actual coverage and regulations are subject to the latest announcements from the NHIA and TFDA.
Is the 'anti-aging HBOT program' promoted by longevity clinics worth doing?
For anti-aging, the benefits are unproven and not an approved use, with risks such as ear barotrauma and oxygen toxicity, as well as significant cost and time commitment. Claims of 'reversing aging' or 'restoring youth' should be viewed conservatively—they are marketing language, not proven effects. If you have a legitimate medical indication for hyperbaric oxygen therapy, it should be evaluated by a physician; using it for anti-aging lacks evidence.
Are hyperbaric oxygen chambers and commercial 'wellness oxygen chambers' the same?
Be careful to distinguish. Standard hyperbaric oxygen therapy is pressurized pure oxygen treatment administered by medical professionals in a medical facility. Commercial 'oxygen chambers' in wellness centers may differ in pressure, equipment, and operator qualifications, with no guarantee of safety or efficacy. The FDA has issued warnings about safety issues with non-medical settings. If you have a legitimate medical need, go to a qualified medical facility and be evaluated by a physician.
