On the other hand, a paper on 'Effects of Exposure to Carbon Dioxide and Human Bioeffluents on Cognitive Performance' (2015) concludes that 'only exposures to bioeffluents when CO2 reached 3,000 ppm significantly affected performance of some cognitive tasks. Increased arousal level at this exposure can be used to explain the observed results.'. https://backend.orbit.dtu.dk/ws/portalfiles/portal/125818556/1_s2.0_S187770581502768X_main.pdf https://backend.orbit.dtu.dk/ws/portalfiles/portal/125818556...
