New research suggests that air pollution may increase the risk of suicidal thoughts and death by suicide both in the short term and long term. This study points to the impact of environmental factors on individuals' mental health.
Extensive Analyses on Pollution and Suicide
A recent analysis published in the Journal of Epidemiology & Community Health provides evidence that exposure to fine particulate matter (PM2.5 and PM10) in the short term, as well as long-term exposure to nitrogen dioxide (NO2) and PM2.5, increases the risk of death by suicide, suicide attempts, and suicidal thoughts. Researchers reviewed over 40 studies that examined various types of air pollution, noise, light, and water.

Serious Implications for Public Health
According to Eurostat data, over 720,000 people worldwide die by suicide each year, and in the European Union, more than 48,000 people lost their lives to self-harm in 2023. The authors of this research emphasize that the causes of suicide are complex and multifaceted, involving individual, biological, cultural, and social factors.
These findings contribute to a better understanding of the role of environmental exposures in suicide risk. However, environmental hazards are still not fully understood. The connection between air pollution and suicide may relate to various mechanisms. For example, air and water pollution are linked to neurological effects that can impact brain function and mood states.
In this context, Susana Al-Halabi, a psychology professor at the University of Oviedo in Spain, stated that pollutants can lead to the creation of more vulnerable social environments. She emphasized the need for further research to examine the cumulative effects of these environmental exposures and their role in shaping suicide risk.
The authors of this article stressed the importance of identifying environmental exposures as modifiable risk factors in suicide prevention efforts. In the presence of suicidal thoughts, individuals can reach out to international organizations for support through hotlines available in 32 countries.
