The Influence of Air Quality on Health and Learning


I recently posted two very long posts, on the influence of acoustics and greenery on learning, respectively, which once were slated to be part of a book that I just couldn’t scrounge the time together to complete. One of the chapters-to-be was on the importance of air quality in learning — and damn, how timely it would have been if I could have pulled that all together pre-COVID-19?!

Oh well. Instead, in the attempt to exorcise the never-to-be-completed book, as well as to close the chapter on this blog and move into more thinking and writing on language and literacy, I posted those two chapters and have been in the process of moving on.

While I most likely won’t ever write that book, I’d still like to highlight the critical importance of air quality in schools and learning, which has become all the more apparent during a time of a respiratory virus, but which is important at all times. And since I don’t have the time to write it all up in full, I’ll post links to the threads that I had laying about in a document instead, and let you, dear reader, complete the thoughts:

The Health Impacts of Air Pollution

Roth and his team looked at students taking exams on different days – and also measured how much pollution was in the air on those given days. All other variables remained the same: The exams were taken by students of similar levels of education, in the same place, but over multiple days.

He found that the variation in average results were staggeringly different. The most polluted days correlated with the worst test scores. On days where the air quality was cleanest, students performed better.

To determine the long-term effects, Roth followed up to see what impact this had eight to 10 years later. Those who performed worst on the most polluted days were more likely to end up in a lower-ranked university and were also earning less, because the exam in question was so important for future education.

The Impact of Indoor Air Quality on Learning

When the level of fresh air in the classrooms was increased, the students performed up to seven per cent better than when they were working on the tests in their usual indoor climates. The study also revealed that the students did not themselves notice that they were not quite as astute in the poorer climate.

Southern California’s air agency, the South Coast Air Quality Management District, earmarked settlements from polluting companies and other funds to cover the cost of such filtration at about 80 schools near freeways or other pollution sources. Nothing’s preventing other states from following the same model.

“The technology is well established, the installation is straightforward and the maintenance is simple,” said district spokesman Sam Atwood, who doesn’t recall officials from other states getting in touch to learn from his agency’s experience.
