Junk article. It's certainly not a "holy grail"...the study just measured telomere length after HBOT. Even meditation has been shown to reduce telomere length. It certainly didn't "reverse human aging". HN people: please stop posting these junk newspaper articles that completely misrepresent the science.

My guess is that the shortening of telomeres—and the presumed aging effects—is evolutionarily beneficial because it sets an expiration date on your life. If people could live forever they may prohibit other younger and genetically different people from reproducing and introducing variety in the gene pool. Certainly having wealthier people live forever now would be bad from a social perspective. Time is really the big…
With biomedical and technological advancements, this scenario is highly likely. At some point in the future, I can envision almost a divergence in human species - those who age naturally and live similar to how we do today, and those who’s wealth has afforded them medical and technical enhancements prolonging their lives, enhancing their abilities, and allowing them to control vast amounts of resources. Perhaps they…
Higher concentrations of oxygen from your respiratory system would likely signal the need in your entire body to upregulate cell division, due to oxidative stress both internal and external. It could also kick in metabolic processes that are not as efficient is substantially lower lower O2 partial pressure environments.
Nevermind the fire hazard. Pro-Tip: With enough 02 around, and nothing else to get in the way, everything burns with comparatively little inducement to do so.

There were a few other good searches I did long ago for another random walk of whimsy, but I seem to have lost track of them. I'll see if I can find them again.
I eagerly await the coming flood of DIY oxygen chamber tutorials. Hopefully no one gets hurt. FWIW: high concentration O2 is known to be toxic in other ways. It causes lung inflamation at least (oxygen is, after all, highly reactive and tends to break up lots of different molecules). I think there's a real possibility that this does more harm than good.

Why would oxygen shortage lead to cell generation ? If I regularly choke myself, will I end up living longer ?
Hormesis is a fairly common theme in human biology. We seem to be at our best when under mild stressors.
(from Wikipedia)
I had never heard of hormesis before. Fascinating and a bit counter intuitive
Telomeres are intentionally shortened by the body, a process which is no doubt favored by evolution. While we don't know why for sure, it is entirely possible that telomere shortening actually lengthens life. As telomeres become shorter, cell division becomes slower and metabolism decreases. This means that an older person's cells will reproduce at a slower rate than a younger person's in general. If we suppose that…
Seems like pure speculation. There are a thousand different mechanisms that would explain it and would not mean "there is some health benefit". Is there a health benefit of white hair? Of wrinkles? Of ...? Quite the opposite seems true in fact. Evolution tries make us be on our peak at the reproductive age, and a lot of that happens after is a byproduct/consequence of this, not just for health benefits. Most (all?) o…

Ozone (O3) is definitely the one that is very reactive and bad for your lungs.
It's a known thing in diving planning, here's a wikipedia article on it: https://en.wikipedia.org/wiki/Oxygen_toxicity
Now, I'm sure these chambers aren't at those pressures. But everything is likely linear, and the thing they're "curing" is literally what we currently consider to be the normal baseline! Even a very small effect will swamp whatever longevity benefits they're seeing are.

You mean meditation have been shown to increase telomeres' length, right?

The main outcome of the study was to measure an in improvement in cognition: https://www.aging-us.com/article/202188/text
There doesn't seem to be any mention of cognition as a result in the article. The primary endpoint was telomere length.
