Dr Mary Abed Al Ahad of the University of St Andrews, who led the study, said policies to tackle air pollution and a shift to renewable energy could help ease the burden on hospitals of people with both physical and mental illnesses in the long term.
Pollution exposure linked to mental health hospital admissions, says study Researchers from St Andrews found rise in nitrogen dioxide exposure associated with higher admissions.
Previously published research on the health effects of long-term exposure to ambient air pollution has tended to emphasise deaths rather than hospital admissions, and physical, rather than mental, ill health, the researchers said.
The research, involving more than 200,000 people in Scotland, found an increase in exposure to nitrogen dioxide in particular was associated with a higher number of people being admitted to hospital for behaviour disorders and mental illnesses.
The study found that air pollution was linked to increased risks of hospital admission for mental health, as well as physical illness.
