Carbon dioxide is one of just a very few air quality problems for which you have strong inborn biological detection systems. If you don't feel like it's suffocating you, it isn't.
Of course, these CO2 levels are smaller by at least one order of magnitude than what could cause suffocation. I overdramatized the fact that the air quality was really, really bad.
Based on every article I found, above 1000 ppm clearly affects sleep quality, cognitive performance, it causes headaches, etc. so 3600ppm is generally considered really bad.
Even if CO2 would be harmless in itself, it is a good indicator for bad ventillation.

Sleep quality and cognitive performance are often difficult to perceive in yourself.
Headaches aren't like that at all. If every article you found states that CO2 above 1000 ppm causes headaches, that should reflect poorly on everything else in all of those articles.
