Sleep Quality & CO2: The Key to Unlocking Restorative Sleep
CO2 is a measurable, controllable variable in sleep quality. Integrating accurate sensing enables engineers to transform air quality data into meaningful health outcomes.
CO2: A hidden sleep disruptor
- Carbon dioxide (CO2) accumulates in enclosed bedrooms overnight
- Primary drivers: human respiration & inadequate ventilation
- Invisible, odorless and often unmonitored
Indoor CO2 dynamics in a typical bedroom
- >1,000 ppm within ~1 hour with a single occupant
- 3,000-5,000 ppm by morning in poorly ventilated spaces
- Exceeds comfort & health thresholds (e.g., LEED guidelines)
Impact on sleep performance
Elevated overnight CO2 exposure correlates with:
- Up to 20% more frequent awakenings
- Increased sleep latency
- Up to 50% more restlessness
- Reduced deep restorative sleep cycles
- Elevated cortisol stress leves
