An international team of researchers from Denmark and China showed that carbon dioxide levels in the bedroom
Researchers have measured over 100households in Denmark and Shanghai. They studied the air quality in the bedroom, tracked the quality of sleep, and tested the cognitive abilities of the participants in the experiment the next day. The scientists collected similar data from volunteers who spent the night in a climate chamber, a transparent plexiglass box that allows you to monitor and analyze air quality during the night.
The analysis showed the relationship between the concentrationcarbon dioxide and performance: high concentrations of carbon dioxide negatively affect the ability to concentrate, comprehend information and respond to external impulses.
The researchers found that at a concentrationCO₂ below 750 ppm (with a good ventilation system and air quality outside the window) has no negative effect on the quality of sleep. In rooms with a concentration of gas from 1,150 parts per million, the quality of sleep noticeably deteriorates, and at a concentration above 2,600 parts, performance the next day decreases.
Researchers note that in urbanenvironments with significant air pollution outside the window, simple ventilation may not be enough. In this case, an artificial ventilation system may be the best solution.
