As air pollution levels surge in Delhi-NCR, concerns about its effects on health have never been more pressing. From respiratory issues to long-term Cardiovascular Diseases (CVDs), the consequences of breathing in polluted air are far-reaching. In response, doctors and healthcare professionals witness many people turning to immunity boosters—vitamins, supplements, and nutrient-rich diets—as a defence mechanism. But can these boosters really shield us from the harmful effects of air pollution? We spoke to our expert, Dr Shrey Kumar Srivastav, Senior Consultant and Physician - Sharda Hospital, and here’s what he shared with us.
Understanding The Impact Of Air Pollution On Immunity
According to Dr Srivastav, air pollution is more than just smog and fine particles; it's a complex mix of harmful substances, including Particulate Matter (PM2.5), Nitrogen Dioxide (NO2), carbon monoxide, and Volatile Organic Compounds (VOCs). “These pollutants enter the body primarily through inhalation, leading to oxidative stress, inflammation, and immune dysfunction,” he shared.
Adding to that, he explained that chronic exposure to polluted air has been linked to:
- Increased vulnerability to respiratory infections
- Exacerbation of conditions like asthma, bronchitis, and Chronic Obstructive Pulmonary Disease (COPD)
- Weakening of the immune response, making it harder for the body to fight off pathogens
With such dire effects, boosting immunity has become a priority for those living in highly polluted areas.

Can Immunity Boosters Help Combat Current Air Pollution
Immunity boosters include a range of vitamins, minerals, and compounds believed to strengthen the immune system. “While it can’t eliminate pollutants or prevent exposure, they may mitigate some of the damage caused by air pollution,” Dr Srivastav explained. Here’s how:
1. Neutralising Free Radicals
Pollutants generate free radicals that damage cells and tissues, contributing to oxidative stress. Antioxidants, such as Vitamin C and Vitamin E, can neutralise these harmful molecules, reducing cellular damage.
2. Reducing Inflammation
Chronic inflammation triggered by pollutants can weaken immunity. Anti-inflammatory compounds, like omega-3 fatty acids and turmeric, may help calm this response.
3. Strengthening the Respiratory System
Nutrients like Vitamin D and zinc play a crucial role in maintaining the health of the respiratory system, making it more resilient to pollutants.
4. Supporting Overall Immune Function
A well-nourished immune system is better equipped to fend off infections that could be exacerbated by pollution.
Immunity Boosters You Can Try
Your body’s defences are only as strong as the care you provide. Here are some common yet effective immunity boosters you can try:
- Vitamin C for reducing inflammation
- Vitamin D for immune modulation and reducing the risk of respiratory infections
- Zinc to help regulate immune responses and reduce oxidative stress
- Omega-3 fatty acids to counteract the effects of pollutants.
- Herbal supplements (like turmeric, ginger, and echinacea) for their immune-boosting and anti-inflammatory properties
Bottomline
Immunity boosters can be a valuable addition to your toolkit for combating air pollution as the Air Quality Index (AQI) soars alarming levels, but they’re not a standalone solution. Prioritise a holistic approach, combining good nutrition, and protective measures, for cleaner air to safeguard your health.
