Thanks, never thought about that, I'll sometimes wake up in the middle of the night with a sort of claustrophobic feeling and need to take a deep breath when there is no ventilation or windows open. Girlfriend always complain that I must leave everything open because of that. Do you use a Co2 meter to monitor?

Yeah, I bought two co2 meters - one for each room - after a hackernews thread about losing cognitive function with rising levels. So I only bought them to improve work. Really wanted to know how often and long I have to open the windows. Often I closed the doors to sleep as the noise from neighbors woke me up sometimes. Was completely dumbfounded to wake up to >2000 ppm co2 in my bedroom. And my meter doesn't even go much further as anything above 2k is considered "get fresh air now". Now I only close the door to the bathroom and keep everything else open.

  I've had similar experiences after getting CO2 monitors as well. I suspect 80+% of people are sleeping with CO2 levels that are negatively impacting their cognitive function.
