Air pollution is known to be a cause of breathing problems. However, there's new evidence which suggests that it can also be a cause of heart disease, stroke, and eye problems, among others. Now, a new study says that the effects of polluted air may extend to mental health as well. A systematic review published in the Journal of Epidemiology & Community Health has found a link between exposure to certain air pollutants and a higher risk of suicide, suicide attempts and suicidal thoughts.
For the study, the researchers looked at evidence from studies conducted in different populations and examined several forms of environmental pollution. The strongest evidence in the review involved fine particulate matter, particularly PM2.5 and PM10, as well as nitrogen dioxide (NO2). Researchers found that both short-term and long-term exposure to some of these pollutants was associated with suicide-related outcomes.
