The Cognitive Impact of Fresh Air

A consistent argument I’ve made here is that the physical environment of a school alone can have a significant impact.

So here’s a really interesting study that demonstrated that healthier air quality (in the form of low CO2 levels) can double cognitive scores.

“The results are striking,” lead researcher Joseph Allen, director of the Healthy Buildings program at Harvard, told Ars. Researchers knew that air quality would likely affect cognitive function and work performance, but earlier studies included few people and reported subjective data. We didn’t expect to see that high quality air could double cognitive scores, Allen said.

Can you imagine if any school ever posted results where they doubled cognitive scores—or doubled any score, for that matter? To say that the “results are striking” would be an understatement.

In this study, the researchers looked specifically at office workers. But most workers in offices at least work in buildings where there is no mold growing on the ceiling, where there is no water that will run down the chalkboard whenever it rains, and where there is no thick black-green “dust” that will coat your desks on a daily basis.

Whereas we find it somehow OK to send off thousands of our nations children each day to schools where this is the everyday norm.

So if ventilating the air can DOUBLE the cognitive scores of office workers — imagine, just imagine, what it could do for the long-term well-being and academic performance of students. . .

Access to fresh air, greenery, and natural light should be a right, not a luxury, for all of our children.
