As students return to school for a new school year in many states, it is essential for school districts to consider the effects of air pollution on students and implement strategies to mitigate these effects.

How Does Poor Indoor Air Quality (IAQ) Affect Children in Schools?

Productivity: Better Air Quality Improves Learning and Cognition

Teachers make a variety of efforts to maximize the effectiveness of their students’ learning experience; customized teaching strategies, optimized classroom layouts, and detailed lesson plans are just a few of the factors that teachers consider.

But a crucial factor in a student’s success is the air they breathe. Research has demonstrated the effects of air quality on several key aspects of cognition.

In a 2016 study, researchers tested how air quality affected the cognitive performance of office workers. Study participants spent six full work days (eight hours) in environmentally-controlled office spaces, blind to test conditions. On each of the days, they were exposed to different levels of pollutants (VOCs and CO2), and the spaces were ventilated at a different rate.

Of the nine domains of cognitive function tested, researchers found that all were improved by higher air quality. Cognitive scores averaged 61% higher on days with better air quality and 101% higher on days with both better air quality and improved ventilation than on days that represented typical office air quality conditions.

Sharp cognitive function...
