How did you measure this?
- ip26 7y agoI never had access to co2 meters when I was a teenager, but I had the same suspicion. Some rooms regularly left me feeling stifled & drowsy, and the first breath of fresh air out the door would rouse me in an instant. I plan on sending my own kids to school with a meter one day just to see. The reason I don't believe it was just boredom is the worst offender was always choir- a class I loved, and a class with obviously elevated production of co2.
- shakna 7y agoThis one is actually backed up by a few studies like this [0] one. There's not enough studies to actually say conclusively that it's common or the usual cause, but there's enough to suggest it should be under consideration.

- lilgreenland 7y agoI have a CO2 meter in my classroom. It would get up to 2000 ppm if the fan was off. At that level you might feel some very mild effects on energy and focus. I keep the air intake on always now.
