Been measuring CO₂ levels lately: bedroom, office, cars, etc. Elevated CO₂ creates a silent drag on cognitive performance and sleep quality. Feels like brain fog and fatigue. Traveled this weekend and was curious about levels in the hotels and casinos: SF hotel: 479✅ Vegas hotel: 637 ✅ Aria casino: 446✅ Car: 1022❌ 1000+ ppm cognitive function begins to drop. The measurement in the casino was taken in the morning when not many people were there so night time levels may be higher. Both hotels had good ventilation. The car was a surprise find.

CO2 monitors have become popular tools people can use to estimate their indoor air quality. A new study was recently published that explores how we can use them to optimise occupancy thresholds and identify problem locations. Actual practical science!!! 🧵
