The claims for hyperbaric oxygen therapy for longevity and cognitive enhancement are largely unsubstantiated.

“I don't think it's harmful but I think all of the claims are nonsense you know tiir extension is totally irrelevant if you actually look at the studies they're the worst done studies I've ever seen in my life I'm sure you've seen some of these where it's like you put these people in a hyperbaric chamber and then watch them do cognitive tasks after and they're so much better well the fine is they don't even have Placebo groups here like can you imagine doing a study without a placebo group or your placebo group doesn't go into a sham chamber”
