Jakarta - The results of a study by Harbin Medical University and Cranfield University show a link between long-term exposure to air pollution and the risk of depression, a mental health condition characterized by persistent feelings of sadness and loss of interest in previously enjoyed activities.
According to a Hindustan Times report on Monday (7/4), new research published in Environmental Science and Ecotechnology shows a strong link between long-term exposure to air pollution and a higher risk of depression.
The study tracked the conditions of adults aged 45 and over in China for seven years, focusing on how six air pollutants can affect mental health.
The results of the study showed that sulfur dioxide (SO₂) is the pollutant most strongly associated with an increased risk of depression.
Carbon monoxide (CO) and fine particles (PM2.5) also play a role in increasing the likelihood of developing mental health problems.
Further research suggests that exposure to this mix of pollutants may significantly increase the risk of depression.
Researchers explain that air pollutants can affect the central nervous system by triggering oxidative stress and inflammation.
These effects can occur through a variety of pathways, including the bloodstream, the trigeminal nerve, or even olfactory receptor neurons.
However, researchers say more research is needed to fully understand how air pollution contributes to mental health problems.
