“My wife and I keep seeing hyperbaric oxygen advertised for anti-aging. There’s a place near us charging $150 a session and a clinic an hour away that wants $30,000 for a program. There are also chambers on the internet you can buy for your house. Is any of this real, and if it is, which version do we need?”
The advertising is hard to miss now. Hyperbaric chambers turn up in spa suites and spare bedrooms, in TikTok unboxing videos, in clinic promotions selling anti-aging packages, and in recovery footage from LeBron James and Novak Djokovic. Private clubs and wellness centers offer individual sessions starting around $50, and some longevity clinics offer twelve-week packages for more than $50,000.
So is this all hype or are there real benefits?
The technology is not new. Hospitals have used it since 1939 for decompression sickness, carbon monoxide poisoning, and wounds that will not close. The FDA’s cleared list still includes about fourteen conditions, but none are related to aging. The longevity application arrived only in 2020. That oxygen under pressure reaches starved tissue is settled science. Whether doing it sixty times measurably slows aging in a healthy person is a different question.
