Findings from previous research suggest that indoor air pollution and poor ventilation can impair people’s morale and awareness - in a study published last year from University College London. .

Researchers have previously concluded that air circulation and adjusting the amount of CO 2 in the room can help minimize this unwanted effect. However, new research shows that in the future, climate change may make matters worse.

To study those effects, the scientists looked at how the level of CO 2 increase can affect a typical classroom, with a certain number of students, the size of the class, as well as the rate at which the class increases. normal ventilation.

They also used two different climate models - one that reduced CO 2 and one that was expected if the air condition continued to deteriorate.

Results showed that, in the model which air quality contains less CO 2 than the academic performance and cognitive abilities in the classroom can be reduced by 25%, while a model does not reduce emissions, the effect Learning outcomes can be reduced by up to 50%.

Although previous studies have shown a correlation between brain function and CO 2 , there is currently not much information on why polluted air affects our brain in a way it works.

As noted by Gizmodo, a previous study on the correlation of CO 2 with brain function showed that an increase of at least 5% of CO 2 emissions was sufficient to hinder brain activity.

However, as the researchers noted, all of the detrimental effects of CO 2 on mental activity can still be mitigated by efforts to reduce emissions and prevent climate change.
