Key Takeaways

  • Monitor indoor CO2 levels – Outdoor baseline is 400-450 ppm; indoors should stay below 1000 ppm to avoid brain fog and fatigue.
  • Ventilate high-occupancy spaces – Elevators, classrooms, and offices often exceed 2000+ ppm CO2; open windows or use air purifiers.
  • Check sauna ventilation – Unventilated dry saunas can reach 5000+ ppm CO2; ensure proper airflow to avoid CO2 buildup.
  • Optimize air quality for performance – Lower CO2 levels correlate with improved chess moves and SAT scores; prioritize clean air for focus.
