A new study has revealed that small increases in people’s exposure to air pollution is linked to significant rises in depression and anxiety. Those living in places with higher levels of particle pollution were twice as likely to experience mental health problems as those in the least polluted areas.
The researchers wanted to highlight that unlike other factors impacting mental health, such as genetics, air pollution can be prevented.
