Matt explains in this video how high concentrations of CO2 can slow down your brain activity, as new research suggests. This new study points that a CO2 concentration of 1000ppm can reduce the ability to focus and function properly. An unventilated space such as... a classroom per se, with lots of people exhaling CO2 can lead to high CO2 concentrations.
22 participants took place in this test. They were asked to perform a strategic management simulation in an environment containing 600ppm, 1000ppm and 2500ppm of CO2. Watch the video to see the results.
