Aware of this research, my housemates tested their air quality and got levels between 1000 and 3000 ppm, around the level of the worst high-CO2 conditions in the studies. They started leaving their windows open and buying industrial quantities of succulent plants, and the problems mostly disappeared. Since then they’ve spread the word to other people we know afflicted with mysterious fatigue, some of whom have also noticed positive results.

I thought this was going to be an article about fossil fuels and global warming. No it’s much worse. It’s about how some people have measured levels of CO2 in their bedroom that exceed the OSHA workplace safe-exposure limits.

Now i’m wondering if one of the reasons I sleep better in the winter, is the difference in ventilation. Our A/C is a closed system—it only circulates the air in the house. But the wood stove lowers the air pressure slightly and that draws outside air in from the peripheral areas of the house. Tiny cool drafts come out of all the wall outlets and light switches in the winter providing fresh air ventiliation.
