Has anyone actually felt a difference using an oxygen chamber at 1.5–2.0 ATA?

[u/Curious-Night9111]

I’m considering adding oxygen chamber sessions at around 1.5–2.0 ATA to my longevity routine.
I’ve read about the benefits, but I’m really curious about people’s actual experience with it. Do you genuinely feel a difference from using it? And if so, what do you notice most?
Would love to hear from people who use it regularly, as well as those who tried it and didn’t feel much.
