Poor indoor air quality indicated by elevated indoor CO2 concentrations has been linked with impaired cognitive function, yet current findings of the cognitive impact of CO2 are inconsistent. This review summarizes the results from 37 experimental studies that conducted objective cognitive tests with manipulated CO2 concentrations, either through adding pure CO2 or adjusting ventilation rates (the latter also affects other indoor pollutants). Studies with varied designs suggested that both… 

Low Level Carbon Dioxide Indoors—A Pollution Indicator or a Pollutant? A Health-Based Perspective

It is difficult to say with confidence whether low-level CO2 exposures indoors can be linked to health outcomes, but the existing guideline concentrations, which suggest that CO2 levels <1000 ppm represent good indoor air quality and <1500 ppm are acceptable for the general population, appear consistent with the current research.

Effects of Climatic Conditions, Season and Environmental Factors on CO2 Concentrations in Naturally Ventilated Primary Schools in Chile

Between the ages of 6 and 18, children spend between 30 and 42 h a week at school, mostly indoors, where indoor environmental quality is usually deficient and does not favor learning. The difficulty

Respiratory performance of humans exposed to moderate levels of carbon dioxide.

Poor ventilation likely affects respiratory parameters, probably not caused by increased CO2 alone and rather by other pollutants-predominantly human bioeffluents in this work-whose concentrations increased as a result.

Associations of Human Cognitive Abilities with Elevated Carbon Dioxide Concentrations in an Enclosed Chamber

Fifteen participants were exposed in an enclosed environmental chamber to investigate the effects of elevated carbon dioxide (CO2) concentration on their cognitive abilities. Three CO2 conditions

The impact of emissions from an essential oil diffuser on cognitive performance.

Results show that exposure to essential oil emissions caused shortened reaction time at the cost of significantly worse response inhabitation control and memory sensitivity, indicating potentially more impulsive decision-making.

Human health and productivity outcomes of office workers associated with indoor air quality: a systematic review

The review showed that individuals exposed to indoor air quality settings above ASHRAE minimum standards were more likely to experience increased poor levels of health, performance and productivity under these conditions.

Development and application of an indoor carbon dioxide metric.

Indoor carbon dioxide (CO2 ) concentrations have been considered for decades in evaluating indoor air quality (IAQ) and ventilation, and more recently in discussions of the risk of airborne

The effects of warmth and CO2 concentration, with and without bioeffluents, on the emission of CO2 by occupants and physiological responses.

A higher CO2 emission rate is indicated at the higher temperature, at which the subjects were warm, and a lower emission rate in all conditions in which the background CO2 concentration increased.

CO2 Concentrations and Thermal Comfort Analysis at Onsite and Online Educational Environments

In building areas with high occupancy, such as classrooms, transmission routes of SARS-CoV-2 are increased when indoor air quality is deficient. Under this scenario, universities have adopted



Is CO2 an Indoor Pollutant? Direct Effects of Low-to-Moderate CO2 Concentrations on Human Decision-Making Performance

Direct adverse effects of CO2 on human performance may be economically important and may limit energy-saving reductions in outdoor air ventilation per person in buildings.

Do Indoor CO2 Levels Directly Affect Perceived Air Quality, Health, or Work Performance?

Concentrations of CO2 in occupied buildings exceed outdoor concentrations because CO2 is a product of peoples’ metabolism. Indoor CO2 concentrations are indicators of the rates of building

High indoor CO2 concentrations in an office environment increases the transcutaneous CO2 level and sleepiness during cognitive work

It is shown that a high concentration of CO2 in indoor air seem to be one parameter causing physiological effects, which can decrease the facility user's functional ability, and the correct amount of ventilation with relation to the number of people using the facility, functional air distribution, and regular breaks can counteract the decrease in functional ability.

Associations of Cognitive Function Scores with Carbon Dioxide, Ventilation, and Volatile Organic Compound Exposures in Office Workers: A Controlled Exposure Study of Green and Conventional Office Environments

Cognitive function scores were significantly better under Green+ building conditions than in the Conventional building conditions for all nine functional domains, and have wide-ranging implications because this study was designed to reflect conditions that are commonly encountered every day in many indoor environments.

The effect of low ventilation rate with elevated bioeffluent concentration on work performance, perceived indoor air quality, and health symptoms

The experimental condition had an effect on perceived air quality and observed odor intensity only in the beginning of the session, and although the room temperature was controlled in both conditions, the heat was perceived to impair the performance more in Condition B.

Direct human health risks of increased atmospheric carbon dioxide

Preliminary evidence indicates potential health risks at CO2 exposures as low as 1,000 ppm—a threshold that is already exceeded in many indoor environments with increased room occupancy and reduced building ventilation rates, and equivalent to some estimates for urban outdoor air concentrations before 2100.

Current State of the Science: Health Effects and Indoor Environmental Quality

Advances in source characterization include a better understanding of how chemicals are transported and processed within spaces and the role that other factors such as lighting and building design may play in determining health.
