The study's lack of detail and the exaggerated claim about a 20-year age reversal in telomeres make it sound more like a misinterpretation or exaggeration than a credible scientific finding.
Discussion
The 20-year age reversal claim is wildly overstated, but the idea that hyperbaric oxygen could influence telomeres isn't entirely out of the question—just not to that extent.
The study’s vagueness is a red flag—without specifics on methodology or controls, it’s hard to take the 20-year claim seriously, but the general link between oxygen and cellular health isn’t entirely off the rails.
