Says the person that's never tried it, lol.
Alcohol can constrict blood vessels and oxygen, in the case of a hangover, can relax and widen blood vessels through a process called vasodilation. Hyperventilating removes alcohol from most people at three to four times the liver recovery rate which can also help with a hangover.
A pier reviewed study has a very high price tag. No one is going to study something they aren't going to make money off of. Studies are paid for by the owners of the study which is another reason to think they are biased.

This is just a very bad and dangerous epistemological point of view in my opinion. It's basically conspiratorial thinking. This logic means that all of us who
haven't bought the latest developer pitch for timeshares
cannot know that the latest sales pitch and "benefits of developer purchase" won't change our lives and is in fact the best investment we could ever make. I mean, the salesperson will tell you that, and
you haven't tried it this time.
Even if you walk back your logic there to a claim as weak as "well, for a few people I know of, buying developer really worked out for them and they're really enjoying the small perks. There's the "Timeshare Traveller" youtube channel as a cite, as well as RENTER I think. I still wouldn't say that as a general rule, say equivalent to using Advil for a headache, that buying Developer is a good idea. I'd make the claim, backed up by TUG, that everyone would save money buying resale, and in fact, almost
no one should buy Developer at all.
Finally, to the idea that no one studies things they aren't going to make money off of - plenty of people do. It's at least loosely analogous to saying "no one would promote resale timeshares or how to get the most bang for your buck from your timeshare unless they're making money on it". But of course that's not true, and the vast majority of people on TUG do it because we like helping others, or we like puzzles, or like "internet points". And for basically any medical problem, there's a mix of people who want to help humanity and companies that think they could sell something "if it turned out to be true". That we don't even have "sham" studies from the oxygen bar people strongly implies that there is
so little there
there that they can't even make a "compelling to gullible people" study work out.
Note, I'm not rejecting your personal experience - I fully believe you feel better from doing it. I just think that it's far more likely a placebo effect or that you're the one in 300,000 person a la Timeshare Traveller. Look, even with well studied things like coffee being a stimulant and waking people up - some people it puts to sleep. Doesn't mean I'd go around touting coffee as a sleep aid!
