Can Hyperbaric Oxygen Therapy (HBOT) Combat Aging or Slow Aging? Evidence, Risks, and Current Status in Taiwan
Hyperbaric oxygen therapy (HBOT) is a medical treatment in which a patient breathes nearly pure oxygen in a pressurized chamber. It is indicated for specific conditions 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 claims such as 'anti-aging,' 'slowing aging,' and 'reversing aging'—these uses are unproven and not approved indications. The U.S. FDA has warned against marketing HBOT for unapproved uses (including anti-aging). A frequently cited 2020 Israeli study was small, lacked a control group, and had commercial ties between researchers and related clinics, so it cannot be considered evidence for anti-aging. Below is a neutral summary of its approved uses, anti-aging evidence, risks, and current status in Taiwan. Anti-aging use is unproven, carries risks, requires physician evaluation, and is subject to regulations by the Taiwan Food and Drug Administration and National Health Insurance Administration.

What is hyperbaric oxygen therapy? What is it originally used for?
Hyperbaric oxygen therapy involves placing a person in a pressurized chamber and breathing nearly 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 damage, 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 HBOT have not been proven:
- The U.S. FDA has warned that HBOT 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 HBOT has not been proven to slow, stop, or reverse aging; even if certain biomarkers change, it does not equate to living longer or healthier
- The FDA also cautions that promoting unproven uses as effective may delay proper treatment
Is the study on telomere lengthening credible?
A frequently cited study is a 2020 Israeli study (Hachmo et al., Aging journal), but it should be viewed with great caution:
- Small sample size: about 35 healthy individuals aged 64+ participated, with fewer actually analyzed, and it lacked a control group (no placebo)
- It examined surrogate markers (telomere length, senescent T cells), not actual slowing of aging or lifespan extension; the duration of any effect is unknown
- The researchers had commercial ties to related clinics (Aviv/Shamir). Overall, this is a preliminary result requiring independent replication and cannot be considered evidence for anti-aging efficacy
Risks and side effects
Even when used appropriately, HBOT carries risks and requires medical supervision:
- Most common: ear or sinus barotrauma (causing middle ear discomfort or eardrum injury); temporary myopia (usually resolving within weeks); and claustrophobia
- Oxygen toxicity can rarely cause seizures (usually resolving after stopping oxygen) or lung damage; the pressurized oxygen environment also poses a fire risk
- The FDA in 2025 again reminded about safe use—recently, chambers have been used in non-medical wellness settings by non-medical personnel, leading to serious accidents. Treatment should only be performed in qualified medical facilities under physician evaluation
Current status in Taiwan and neutral perspective
In Taiwan, HBOT is a legitimate treatment provided in hospitals, with regulated uses and reimbursement:
- National Health Insurance covers specific indications (e.g., carbon monoxide poisoning, necrotizing soft tissue infections, gas gangrene, decompression sickness, radiation tissue damage, crush injuries, etc., some requiring prior approval); chronic diabetic foot wounds and sudden sensorineural hearing loss are often self-paid
- Using HBOT for 'anti-aging/slowing aging' is outside approved indications (off-label/self-paid), is a medical procedure requiring physician evaluation, and is subject to regulations by the Taiwan Food and Drug Administration and National Health Insurance Administration
- Claims of 'reversing aging,' 'restoring youth,' or 'anti-aging' should be viewed with caution—these are marketing terms from providers, not proven or approved effects. If you have concerns, discuss them with a qualified physician. This page provides neutral information and is not medical advice.
FAQ
Can hyperbaric oxygen therapy combat or slow aging?
Currently, it is unproven and not an approved indication. HBOT is a legitimate medical treatment for specific indications such as carbon monoxide poisoning, decompression sickness, and non-healing wounds; anti-aging is not among the approved indications. The U.S. FDA has warned against marketing HBOT for unapproved uses (including anti-aging), and the mainstream view is that it has not been proven to slow, stop, or reverse aging. This page provides neutral information and is not medical advice.
Is it true that a study showed HBOT lengthens telomeres and reverses aging?
This should be viewed with great caution. A frequently cited study is a 2020 Israeli study (Hachmo et al.), but it was small (about 35 healthy older adults, with fewer analyzed), lacked a control group, and examined surrogate markers such as telomere length rather than actual slowing of aging or lifespan extension. The researchers had commercial ties to related clinics. This is a preliminary result requiring independent replication and cannot be considered evidence for anti-aging efficacy.
What are the risks or side effects of hyperbaric oxygen therapy?
The most common side effects are ear or sinus barotrauma, temporary myopia (usually resolving within weeks), and claustrophobia. Oxygen toxicity can rarely cause seizures or lung damage, and the pressurized oxygen environment poses a fire risk. The FDA in 2025 reminded that serious accidents have occurred in non-medical wellness settings; treatment should only be performed in qualified medical facilities under physician supervision.
Is hyperbaric oxygen therapy covered by National 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 damage, and crush injuries (some require prior approval). Chronic diabetic foot wounds and sudden sensorineural hearing loss are often self-paid. Using HBOT for anti-aging is outside approved indications (off-label/self-paid). Actual coverage and regulations are subject to the latest announcements by the National Health Insurance Administration and the Taiwan Food and Drug Administration.
Are the 'anti-aging HBOT sessions' promoted by longevity clinics worth it?
For anti-aging purposes, the benefits are unproven and not an approved indication, with risks such as ear barotrauma, oxygen toxicity, and significant time and financial costs. Claims of 'reversing aging' or 'restoring youth' should be viewed with caution—they are marketing language, not proven effects. If you have a legitimate medical indication for HBOT, it should be evaluated by a physician. Using it solely for anti-aging lacks evidence-based support.
Are medical HBOT chambers and commercial 'wellness oxygen chambers' the same?
Be careful to distinguish them. Medical HBOT is performed in healthcare facilities by medical professionals using pressurized pure oxygen. Commercial 'oxygen chambers' in wellness settings may differ in pressure, equipment, and operator qualifications, with unproven safety and efficacy. The FDA has issued warnings about safety issues in non-medical settings. If you have a legitimate medical need, seek evaluation at a qualified medical facility.
