Air pollution could be more damaging to our health than previously thought, according to a new study, which found that prolonged exposure to dirty air has a significant impact on our cognitive abilities, especially in older men.

According to the study published Tuesday in the Proceedings of the National Academy of Sciences, breathing polluted air causes a "steep reduction" in scores on verbal and math tests.

Researchers at the International Food Policy Research Institute (IFPRI) examined data from the national China Family Panel Studies longitudinal survey, mapping the cognitive test scores of nearly 32,000 people over the age of 10 between 2010 and 2014 against their exposure to short- and long-term air pollution.

"The damage air pollution has on aging brains likely imposes substantial health and economic cost, considering that cognitive functioning is critical for the elderly to both running daily errands and making high-stakes economic decisions," study author Xiaobo Zhang of Peking University said.

According to the World Health Organization (WHO), nine out of every 10 people on the planet breathe air containing a high level of pollutants, with the worst affected regions being Africa and Asia.
