For some reason, we seem to be very sensitive to those exhaust products (tho it also seems like this might be a dimension that people vary on significantly).
It’s been a while since I took physiology 101, but I think there was a fairly straightforward explanation. My guess from memory would be that it was something like CO2 having to leave your body during breathing and that depending on the amount of CO2 in the air.
CO2 makes up around 0.04% of the air while oxygen makes up 21%. If you go from 21% of oxygen in the air to 20% that’s not a significant change. The corresponding change of CO2 from 0.04 to something on the order of 0.4% is however massive (the real numbers are a bit off because I don’t want to look up how to calculate it but it goes in that direction).
On practical way that helped my to pay more attention to CO2 was to get a device that measures it 24⁄7 and creates alerts when the levels go over a maximum.
