Air Pollution's Link to Suicide Rates
A recent scientific review has shown that exposure to air pollutants, especially particles "PM2.5" and "PM10," is associated with increased indicators of suicide, including deaths, suicide attempts, and suicidal thoughts, although the evidence does not establish a direct causal relationship. The study, which included 45 published studies between 2010 and 2024, indicated that air pollution might affect brain functions and mood through potential biological pathways such as inflammation and oxidative stress. However, the results remain observational and do not confirm that pollution is a direct cause of suicidal behavior. The findings emphasize the importance of conducting additional research that isolates the effects of pollution from accompanying social and psychological factors, warning against relying solely on pollution as a factor in mental health protective measures.
