Abstract
We summarized published evidence linking indoor carbon dioxide (CO2) concentrations with cognitive performance, physiological responses, and health effects. We included studies where CO2 was used as a proxy of ventilation, an indicator of emissions from humans (bioeffluents), and an independent exposure factor. Poor ventilation, demonstrated by high indoor CO2, related to increased prevalence of sick building syndrome symptoms (SBS) and decreased cognitive performance. Exposures to both human bioeffluents and pure CO2 could impair cognitive performance at typical indoor levels of CO2≤5, 000 ppm. The effects could occur at different CO2 levels, depending on the type of cognitive task. A clear physiological explanation of the observed effects requires additional research.
