Coughing, hacking, shortness of breathe, lung disease-absolutely all can be by-products of breathing polluted air. But, according to a study published in the Proceedings of the National Academy of Sciences, prolonged exposure to dirty air has a significant impact on our cognitive abilities, especially in older men. The study maintains that breathing polluted air causes a “steep reduction” in scores on verbal and math tests.
Constantly ingesting polluted air into the lungs could also stimulate an increased risk factor for the development of Alzheimer’s disease or other forms of dementia according to researchers. A sobering statistic: The World Health Organization reports that nine out of every ten people breathe air containing high levels of pollutants with the worst affected regions being Africa and Asia.
University of Washington researchers find that the higher the level of particulates in the air, the greater the impact on mental health. The UW School of Public Health also maintains that spending less time outside because of pollution or living a more sedentary lifestyle can be related to psychological distress or social isolation.
