Hyperbaric Oxygen Therapy: A Trend Worth Avoiding for Healthy People

Hyperbaric oxygen therapy (HBOT) is making waves far beyond its traditional use for medical conditions like decompression sickness and wound healing. Clinics offering HBOT as a wellness treatment are popping up everywhere, promising anti-aging effects, improved performance, and even extended lifespan. While these claims are enticing, they are speculative at best and based on shaky evidence. For healthy individuals, routine exposure to HBOT is more likely to do harm than good, and it’s a trend worth approaching with caution.

What Are Clinics Claiming?

HBOT involves sitting in a pressurized chamber while breathing pure oxygen, dramatically increasing the oxygen levels in your bloodstream. Clinics now market this therapy to healthy clients with promises of tissue repair, reduced inflammation, and cellular rejuvenation. Much of the hype stems from a 2020 Israeli study, which claimed that repeated HBOT sessions lengthened telomeres—the protective caps on chromosomes that are associated with aging. Telomere shortening is often linked to aging and disease, so this finding caused a stir.

But here’s the problem: the study focused on T-cells, a subset of immune cells that naturally show wide variations in telomere length. Experts have criticized the study for misinterpreting the results, suggesting that the observed changes likely reflected natural shifts in immune cell populations rather than genuine telomere elongation. To date, there is no evidence that HBOT has a meaningful impact on telomeres in other cells, let alone on overall longevity.

Despite this, some clinics have seized on the study’s claims to market HBOT as an anti-aging therapy. This is not science—it’s salesmanship.

Why HBOT Could Backfire

While HBOT does have legitimate uses for certain medical conditions, long-term exposure to high oxygen levels carries significant risks. The therapy increases the production of reactive oxygen species (ROS), highly reactive molecules that can damage DNA, proteins, and cell membranes when present in excess. Small amounts of ROS are part of normal cellular processes, but too much causes oxidative stress, a key driver of aging and chronic disease.

For healthy individuals, prolonged or habitual HBOT exposure could accelerate cellular aging rather than prevent it. Key risks include:

Oxidative Damage: Chronic oxidative stress harms cells, particularly in tissues like the lungs and brain, where oxygen levels are tightly regulated.
Inflammation: Paradoxically, while HBOT can reduce inflammation in the short term, repeated exposure may trigger low-grade chronic inflammation, a hallmark of many age-related diseases.
Pulmonary and Neurological Risks: High oxygen levels over long periods can lead to lung inflammation, scarring, and even seizures in extreme cases.

HBOT’s Commercial Ploy

The rapid proliferation of HBOT clinics signals a trend driven more by profit than by science. Clinics charge hefty fees for sessions, often bundling treatments into packages marketed as anti-aging solutions. However, their claims lack strong scientific backing and are often based on misinterpreted or flawed studies, like the Israeli telomere study. While HBOT has clear benefits for specific medical conditions, using it as a routine wellness tool is speculative and unsupported.

What’s particularly troubling is the absence of long-term studies on the effects of habitual HBOT for healthy individuals. The therapy’s risks are well-documented, but its purported benefits for the healthy remain anecdotal and unproven. This makes HBOT more of a commercial gimmick than a credible anti-aging intervention.

A Word of Caution

For healthy individuals, the appeal of HBOT lies in its promise of rejuvenation—but at what cost? Current evidence suggests that the therapy’s risks, including oxidative stress and cellular damage, outweigh its speculative benefits. Until robust research demonstrates its safety and efficacy for long-term use, HBOT should be reserved for its medical indications, not marketed as a lifestyle enhancement.

Clinics offering HBOT as a cure-all for aging and wellness are selling hope, not science. If you’re tempted by the promise of HBOT, remember that well-established methods—like exercise, balanced nutrition, and proper sleep—remain the safest and most effective ways to promote longevity. For now, HBOT is a “wellness” fad that is likely to do more harm than good and a fun billionaire biohacking toy that is fun to show off at parties.
