Wow I didn't realize that submarines and the ISS had such a high level of CO2. I feel noticeably worse when CO2 is above 2000ppm in my house. I've always wanted to have an artificial CO2 scrubber for when the windows are closed, but energetically I would probably be better off opening the windows and heating or cooling the air to compensate. Do submariners and astronauts have impacts to their cognitive abilities from this elevated rate?
- idlewords 3y agoWhether there are cognitive effects is not clear, but it definitely affects their mood and their sleep. It's a touchy subject since astronauts don't like to publicly complain. Scott Kelly talks about it pretty openly in his book; reading between the lines of tech papers on next-generation life support you get the impression that crews insist levels need to get below 2000 ppm for long-duration missions.
