Air pollution linked to higher suicide risk
A scientific review indicates that long-term exposure to air pollution, especially fine particulate matter PM2.5 and nitrogen, is associated with an increased risk of suicide and suicidal thoughts. The likelihood of suicide-related outcomes rises by up to 53% with each 10 microgram per cubic meter increase in air pollution. It is believed that chronic inflammation, the impact of pollutants on the nervous system, and sleep disturbances may contribute to this relationship. However, current studies do not establish a direct cause-and-effect link, and further research is needed to understand the causal and cumulative effects.
