Protecting Your Lungs During Post-Diwali Air Pollution

In short: Post-Diwali air pollution in North India triggers respiratory problems. PM2.5 particles penetrate deep into lungs causing inflammation and breathing difficulties, especially for people with asthma or COPD. Limit outdoor activity when AQI is high, use N95 masks outdoors, keep indoor air clean, stay hydrated, and take prescribed medicines regularly.

The weeks following Diwali bring some of the worst air quality of the year to North India. Firecracker smoke combines with crop stubble burning, vehicle emissions and cooler weather that traps pollutants close to the ground, creating a thick haze across Chandigarh, Panchkula and Mohali. The Air Quality Index often climbs into the 'very poor' and 'severe' categories during this period, and the effect on breathing is immediate — particularly for anyone with asthma, chronic obstructive pulmonary disease or a history of respiratory trouble.

What Makes This Season Particularly Hard on the Lungs

Air pollution is not just unpleasant; it is a direct assault on the respiratory system. PM2.5 — particles smaller than 2.5 micrometres — are the most dangerous component because they slip past the nose and throat and penetrate deep into the lungs, reaching the tiny air sacs where oxygen enters the blood. Once there, they trigger inflammation, thicken mucus and irritate already sensitive airways. For someone with healthy lungs this might mean a dry cough or mild chest tightness, but for someone with asthma or COPD it can mean a serious flare-up within hours of a pollution spike.

In October 2026, cities across the Indo-Gangetic Basin including Chandigarh recorded severe air quality, with pollutant levels many times above safe limits. The combination of firecracker emissions and stagnant meteorological conditions trapped harmful gases and particulate matter, and hospitals across the region reported a surge in patients with aggravated breathing problems. Doctors noted that while new respiratory cases did not rise sharply, existing patients experienced more frequent and severe symptoms — persistent coughing, wheezing and breathlessness.

Recognising When Air Quality Is Affecting You

The signs of pollution-related respiratory distress are often mistaken for a seasonal cold or allergy, but there are clear differences. If you notice a dry, persistent cough that worsens when you step outside, tightness in the chest, more frequent use of your inhaler than usual, difficulty breathing during light activity, or wheezing that was not there before, the air quality is likely affecting your lungs. Children, elderly people and anyone with a pre-existing lung or heart condition are at higher risk, and symptoms in these groups can escalate quickly.

If breathlessness becomes severe, if an asthma reliever inhaler does not provide relief within a few minutes, if lips or fingernails turn blue, or if there is confusion or extreme fatigue, seek medical attention immediately. These are signs that the body is not getting enough oxygen.

Practical Steps to Protect Your Respiratory Health

While you cannot control the outdoor air, there is a great deal you can do to limit exposure and protect your lungs. Check the Air Quality Index before planning outdoor activities — most weather apps and government websites now provide real-time AQI readings. On days when the AQI is above 200, try to stay indoors as much as possible, especially during early morning and late evening when pollution levels tend to peak.

If you must go out, wear a properly fitted N95 or N99 mask. Cloth masks and surgical masks do not filter out PM2.5 particles. Avoid heavy exercise outdoors on high-pollution days; brisk walking or jogging when the AQI is severe increases the amount of polluted air drawn deep into the lungs and can do more harm than good.

Indoors, keep windows and doors closed when outdoor air quality is poor, and if you have an air purifier use it in the room where you spend the most time. Avoid burning incense, candles or mosquito coils indoors, as these add to indoor particulate matter. Stay well hydrated — drinking plenty of water helps the body clear irritants from the respiratory tract. If you have asthma or COPD, take your preventer medicines exactly as prescribed even if you are feeling well; they reduce airway inflammation and make flare-ups less likely.

When Medicines Are Needed

Pollution-triggered respiratory symptoms often require medical treatment. Bronchodilator inhalers such as Salbutamol or Levosalbutamol (reliever inhalers) open narrowed airways and provide quick relief during an asthma attack or breathlessness episode. Steroid inhalers reduce inflammation in the airways and are used regularly as preventers, not during an attack. Some people are prescribed combination inhalers that contain both a bronchodilator and a steroid.

Antihistamines can help if pollution is triggering allergic rhinitis — sneezing, a runny nose and itchy eyes — but they do not treat breathlessness or chest tightness. Saline nasal sprays and steam inhalation can soothe irritated nasal passages and help clear mucus, though they are supportive measures rather than treatments. If you develop a cough that produces coloured or blood-streaked phlegm, a high fever, or symptoms that do not improve with your usual medicines, see a doctor. These may be signs of a respiratory infection, which pollution makes more likely.
