If you’re having trouble sleeping, the cause may be right under your nose: trapped C02 in your bedroom.
Some fascinating research from Brian Just, reported in the Fall Issue of BuildingEnergy, found that among a test group of 22 homes, almost every home had elevated CO2 levels, when bedroom doors were closed at night. Perhaps most importantly, even in older “leaky” homes, CO2 levels spiked to unhealthy levels with doors closed.
Myth Buster. The chart shows that leaky and tight homes both have similar CO2 pollution levels. Surprisingly, the "leaky" house can actually have even higher levels than the newer home, presumably because the new home has better mechanical ventilation overall.
As Just points out, elevated CO2 when sleeping has been linked to “reduced cognitive function…headaches, fatigue, and a sense of “stuffiness,” to name just a few. And the rooms were not even checked for other invisible pollutants such as VOCs. Those could be even more detrimental to health.
