If this turns out to be true I wonder if it'd be practical (given the financial resources) to have pressure sealed rooms that you spend a lot of time in at home (e.g. your office). These could be precisely controlled (O2, CO2 levels, pressure, …) and possibly both increase current and future performance. The main problem seems the time needed to exit because an abrupt loss of pressure would be hazardous. But if you have a well-structured day it might work. This could be very interesting for high earning knowledge workers imo.

Breathing oxygen at a partial pressure over about 0.5 atm causes progressive pulmonary oxygen toxicity (loss of vital capacity). Brief exposures like the treatment protocol described in this paper are fine but it's not something you want to do all day every day. Saturation divers who live under pressure for days are careful to control chamber oxygen pressure below that limit.

Nitrogen is regular air is an anaesthetic. It literally makes you stupid, and the effects increase with pressure. If you want to be smarter you need to replace the nitrogen with helium. The high pitched voices are going to make Zoom meetings hilarious.

So generally working under pressure is totally impractical.

On a more feasible scale, a similar idea could be better air filtration/ventilation. Better ventilation in homes or offices to decrease CO2 levels could be an easier way to achieve a similar effect.

If true this is even bigger, as it indicates new directions to look for cures. No longer stuck on plaques; it may be metabolic, respiratory, or pulmonary. This could be more direct evidence of it.

Well yeah, this is what Darth Vader did to heal his extensive burns and lacerations in his Meditation Chamber.

2ATA is like a 10 meter dive. I don’t think you’d need to decompress after a 90 minute dive like that.

Isn't the Big Blue Room this precisely controlled environment where you're supposed to spend a lot of time in, breathing oxygen?

Depends on your financial resources.
