On whether changes in bedroom CO2 levels affect sleep quality
I was lucky to get my hands on 5 proper co2 sensors from university, while I was teaching and working. So plenty of test places.What I found:-Just a couple of hours in a office, without ventilation spikes the co2 enough to make everyone dizzy and tired by the end of the day. Keeping eye on the meter and ventilating properly, increased everyones productivity and people werent so tired by the end of the day.- Classrooms, with 20-30 people are as bad. co2 rises really fast and makes people dizzy. Most often ventilation is too low, as a cost saving measure.-Closing bedroom door, sleeping alone made bedroom as bad by the morning than classroom or office.-Main culprit seems to be our perfection with insulating and making rooms airtight. I do live in a cold climate, so having open vents or windows is not common half the year. It seems it has not been such a big issue before plastic windows or in older houses. I think it is getting worse with every new building.
