Delhi Air Pollution: Feeling Anxious As AQI Rises? Experts Explain The Mental Health Toll Of Breathing Toxic Air

Ahead of Diwali festivities, Delhi is once again battling its annual air pollution crisis. The city's air quality index (AQI) - which measures PM2.5, fine particulate matter, has crossed 500 in some regions, entering the "hazardous" category, raising health concerns for millions in the capital.

The effects of air pollution are not just limited to physical health. Apart from your lungs and heart, long-term exposure to toxic air can render you feeling anxious, stressed, demotivated and mentally fatigued. The reason behind this is not one-fold. The worsening of mental health due to air pollution is a culmination of many factors.

From particulate matter triggering inflammation and negatively affecting the body’s stress response to restrictions on outdoor activities, disturbance in sleep and lack of physical activity, air pollution contributes to mental health burden in many ways.

Dr Varsha Viswanathan, psychiatrist at Athulya Senior Care and Athulya Geriatric Care Hospital, Chennai, told HealthandMe that particulate matter in polluted air can enter the bloodstream and trigger inflammatory responses.

She explained, “This may lead to oxidative stress and affect brain functions involved in mood regulation, attention, memory and emotional processing. Over time, these changes may contribute to increased irritability, mood disturbances and difficulty managing emotional responses.
