Polluted air may worsen symptoms of depression
POLLUTION may worsen mental illness, according to new research reported in the journal Epidemiology and Psychiatric Sciences.
Doctors analysed 1,860 emergency department admissions for mental disorders over a 12-month period and compared them with pollution levels. Results showed higher levels of ozone correlated with a spike in daily hospital admissions.
Just how ozone levels could have such an effect is unclear, but the researchers from the University of Perugia in Italy say one theory is that pollution reduces levels of the brain chemical dopamine, which is involved in depression and other mental health disorders.
