Breathing polluted air can impact cognitive abilities, researchers say

News

A new study shows breathing polluted air results in a “steep reduction in verbal and math test scores”. 

The data is based on roughly 32,000 people over a four-year period in China. Researchers say older men seemed to be especially susceptible to a drop in cognitive abilities.

The world health organization says 9 out of every 10 people on the planet breathe air containing a high level of pollutants. 

Africa and Asia are listed as the worst affected regions.
