Findings: Suicide is the 10th-leading cause of death in the United States; At least 90 percent of people who die by suicide have a diagnosable mental disorder, according to the American Foundation for Suicide Prevention (AFSP).
Suicide may be linked to air pollution, according to new research that finds spikes in completed suicides in the days following peak pollution levels. Though the notion that suicide and air quality could be linked may not seem intuitive, similar studies in South Korea, Taiwan and Canada have also linked the two. It has long been recognized that deaths by suicide peak in the springtime months, which could be a result of social factors. However, a small but growing body of evidence suggests that physical inflammation might also be to blame.
