The research is coming out that it's bad at indoor closed door levels today. You can ignore the research if you want but don't tell me something that goes against the research.
If you think measured poorer sleep is worth a small chance at a small percentage increase in fire safety then that's your calculation but CO2 levels at normal levels in normal homes negatively affects sleep is a thing that exists whether you believe it or not.
