As winter sets in, the air quality worsens every year across northern India. Delhi's air quality has already deteriorated. Authorities have deployed several measures and restrictions across the National Capital Region to maintain air quality. Pollutants severely impact human health by entering the respiratory system and penetrating deep into the bloodstream. Inhaling fine particulate matter (PM2.5 and PM10) triggers widespread inflammation and oxidative stress, damaging the lungs and worsening conditions like asthma, bronchitis, and COPD. Once these microscopic particles cross into the circulatory system, they restrict blood vessels, elevate blood pressure, and increase the risk of heart attacks and strokes. Over time, chronic exposure to polluted air weakens the immune system, impairs cognitive function, and significantly raises the long-term risk of developing lung cancer.
In an Instagram post, renowned cardiologist Dr. Alok Chopra shared a list of supplements and foods that can help strengthen your defences before pollution peaks.
"The pollution is coming. Are your lungs ready? Delhi's winter air can take a toll on your health," he wrote in the post.
The cardiologist shared the following list:
Dr. Chopra recommends vitamins C, D, B and E, and minerals such as zinc to support immune function.
For a variety of nutrients and plant compounds, add these to your diet:
The expert has also mentioned that you must consult your doctor before adding any supplement to your routine.

Keep prescribed medications accessible, and avoid strenuous outdoor activities.
Everyday habits can increase your exposure to harmful pollutants. Avoid the following:
"While you cannot control air quality on your own, you can take steps to reduce your exposure," he wrote.

Delhi AQI: Is Toxic Air Making You Tired? Impact Of Air Pollution On Energy, Sleep And Concentration

Written by Sambhav KumarIt's Not Just AQI: Why Tiny Particulate Matter Poses A Bigger Health Risk
Written by Sneha Mordani, Edited by Sambhav KumarFine particles such as PM2.5 can enter deep into the lungs and lead to inflammation and oxidative stress in the body. Prolonged exposure may also affect the cardiovascular system and overall physical health.
A Pakistani air quality body has found no evidence linking Lahore's post-Diwali smog to fireworks in India, pointing instead to thousands of crop-residue fires in Pakistan's own Punjab.
Morning chest heaviness should not automatically be attributed to air pollution. Persistent or worsening symptoms warrant medical evaluation, particularly if accompanied by coughing, wheezing or breathlessness.
The Pakistan report said the available evidence did not support attributing Lahore's poor air quality after Diwali to fireworks across the border.
India should retain the AQI for public advisories but must publish uncapped PM2.5 and PM10 concentrations alongside it. An index may have a ceiling. Pollution does not.
