Mental well-being is affected by several factors, like genetics, social conditioning and environmental conditions. Researchers are continuously looking into these factors, and several studies have shown that the environment plays an important role in mental health.

In a study conducted jointly in the United States and Denmark, researchers looked into the potential correlation between environmental pollution and the heightened risk of developing psychiatric disorders like schizophrenia, bipolar, personality disorder, Parkinson's disease, major depression, and epilepsy in relation to pollution exposure.

Environment and other socioeconomic factors

The researchers found that individuals residing in highly polluted regions during their formative years showed greater susceptibility to schizophrenia, depression, bipolar and personality disorders. Similarly, in the U.S., regions with greater air pollution levels showed higher risks of depression and bipolar disorder compared to less polluted areas. 

However, while a significant association was noted, a limitation of the research was the absence of causation, urging consideration for other influential factors yet to be accounted for.

Another study focusing on pediatric psychiatric disorders similarly revealed a disturbing trend. Short-term exposure to fine particulate matter, specifically PM2.5, was found to worsen some mental health issues, which then resulted in an increased number of children getting sent to the emergency room.

These combined findings emphasize the importance of addressing environmental factors in mental health research. In a study, disadvantaged places and neighborhoods that are already burdened with various socioeconomic challenges also showed a higher susceptibility to the negative effects of air pollution on mental health. The study emphasized anxiety disorders and increasing the risk of suicide among residents of the said areas.
