The claimWhat Steve actually said

Aoki has described himself as being 'really into bio-hacking' and has fitted his home with a hyperbaric oxygen chamber, cold plunges, saunas and light therapy. In this interview he says he uses the chamber every day when he is at home, framing it as an attempt to lengthen his life rather than to treat a condition.

Why it mattersWhy this matters for longevity

Surrogate markers like telomere length are routinely reported as if they were longevity outcomes, and they are not

Home chambers are expensive and are being sold on claims the clinical literature does not carry

Hyperbaric oxygen has genuine approved medical uses, and blurring those with wellness marketing makes the real ones harder to talk about

The evidenceWhat the science says

A randomised controlled trial in Aging by Hadanny and colleagues gave healthy older adults 60 daily hyperbaric sessions and reported improvements on some cognitive measures, chiefly attention and processing speed, versus controls. A separate prospective trial from the same group reported increased telomere length and fewer senescent T-cells in isolated blood cells after a similar protocol. Hyperbaric oxygen itself is well established for conditions such as decompression sickness, carbon monoxide poisoning, and certain non-healing wounds.

What none of this shows is a longer life. Both studies were small, short, run by overlapping investigators at a single centre, and used surrogate endpoints; the telomere study had no control group at all, and telomere length in blood cells is a marker whose relationship to lifespan in humans is contested rather than settled. There is no trial of hyperbaric oxygen with mortality or lifespan as an endpoint. There are also real costs: sessions are lengthy and repeated, chambers are expensive, and middle ear barotrauma is the common adverse event, reported in a meaningful minority of patients depending on compression rate.

TakeawayThe honest takeaway

The practical lesson

If you are drawn to hyperbaric oxygen, treat it as an unproven experiment with a real price tag rather than a longevity intervention, and get sleep, training and blood pressure right first.

SupplementsThe supplement angle: Antioxidant supplements

Support a habit, do not replace one

High-dose antioxidant supplements are often sold alongside oxygen therapies, and the trial evidence for them in healthy people is weak to neutral. Nothing here is a reason to add one, and some interact with medications.

Supplements can support good habits. They do not replace sleep, movement, nutrition, or medical care. Talk with your healthcare provider before starting anything new.
