Breathing polluted air daily? Study says it could make you feel anxious, low and even depressed

A study from Harbin Medical University suggests that long-term exposure to air pollution, particularly sulfur dioxide, is linked to higher depression risks.

Breathing in polluted air every day might be doing more than just harming your lungs, it could be affecting your mood too. A new study published in Environmental Science and Ecotechnology suggests a strong link between long-term exposure to air pollution and a higher risk of depression.

Conducted by Harbin Medical University and Cranfield University, the research tracked adults over 45 in China for seven years, focusing on how six common air pollutants may be impacting mental health.

Air pollution and mental health risks

According to the study, sulfur dioxide (SO₂) emerged as the top pollutant most strongly linked to an increased risk of depression. Carbon monoxide (CO) and fine particulate matter (PM2.5) also played a role in raising the likelihood of developing mental health issues. The research further suggests that being exposed to a mix of these pollutants can significantly amplify the risk of depression.

Air pollutants may affect the central nervous system, leading to mental health issues such as depression.

Depression is a mood disorder marked by persistent feelings of sadness and a loss of interest in daily activities. Often referred to as clinical depression, it can cause symptoms such as anxiety, fatigue, irritability, insomnia, and a lack of enjoyment in things once loved, according to the Mayo Clinic. If someone is experiencing these symptoms, it’s important to seek help from a medical professional.
