Hyderabad's Winter Smog & Your Lungs: A Chest Specialist's Guide
By Dr. Md. Mukarram Ali, MBBS, DTCD, FCCP (USA), DNB — Consultant Pulmonologist & Chest Specialist, Faith Hospital, Hyderabad. Medically written and reviewed for patients in Hyderabad.
Quick answer
- Hyderabad's air quality drops every October–January because cool, still air traps dust and vehicle smoke close to the ground.
- Fine particles (PM2.5) reach deep into the lungs and can trigger cough, wheeze and flare-ups of asthma and COPD.
- Check the AQI daily, shift outdoor exercise to the cleaner part of the day, use a well-fitted N95 mask on bad days, and never stop your inhalers on your own.
- See a chest specialist if a cough lasts more than 2–3 weeks or breathlessness wakes you at night.
Why Hyderabad's Air Gets Worse Every Winter
Every winter, my OPD fills with the same complaint: "Doctor, the cough started when the weather turned." There is a scientific reason. In winter, the air near the ground cools and a layer of warmer air sits above it — a temperature inversion. Pollution from traffic, construction dust, burning waste and industry cannot rise and disperse, so it hangs at breathing level. According to the Centre for Science and Environment analysis of CPCB data, Hyderabad's average PM2.5 between October 2024 and January 2025 was 52 µg/m³ — making it the third most polluted of India's six megacities that winter, with local spikes much higher in industrial pockets such as Sanathnagar.
That number is well above what the World Health Organization considers safe for long-term exposure. In practical terms, the city's air on many winter mornings is a daily stress test for your airways.
What PM2.5 Actually Does Inside Your Lungs
PM2.5 means particles smaller than 2.5 micrometres — about 30 times thinner than a human hair. The nose and throat cannot filter them. They travel to the smallest airways and air sacs, where they cause irritation and inflammation. The WHO links long-term exposure to chronic lung disease, lung infections, heart disease and stroke.
- Short term: throat irritation, dry cough, a blocked or runny nose, chest tightness and wheezing.
- In people with asthma or COPD: more frequent attacks and a higher need for reliever inhalers.
- Long term: reduced lung function, more chest infections and worsening of existing lung disease.
Who Is Most at Risk During the Smog Season?
- People with asthma, COPD, bronchiectasis or lungs scarred by old TB
- Adults over 60 and young children, whose lungs are more sensitive
- People with diabetes, heart disease or kidney disease
- Smokers and people exposed to second-hand smoke
- Traffic police, delivery riders, auto drivers and construction workers who spend hours outdoors
- Pregnant women
Symptoms You Should Not Ignore
A mild sore throat on a smoggy day is common. These, however, deserve a medical review:
- A cough lasting more than 2–3 weeks
- Wheezing or a whistling sound while breathing
- Breathlessness while climbing stairs that you did not have before
- Waking up at night with cough or a tight chest
- Needing your reliever inhaler more than twice a week
A cough that refuses to settle has many possible causes, not only pollution. Read our guide on cough lasting more than 3 weeks to understand what your doctor will check.
How to Read the AQI and Plan Your Day
The Air Quality Index (AQI) turns pollution levels into a simple scale. You can check live readings for Hyderabad stations on the CPCB national AQI portal or the SAMEER app.
| AQI | Category | What to do |
|---|---|---|
| 0–50 | Good | Normal outdoor activity |
| 51–100 | Satisfactory | Sensitive people watch for symptoms |
| 101–200 | Moderate | Asthma/COPD patients reduce long outdoor exertion |
| 201–300 | Poor | Avoid outdoor exercise; wear an N95 outdoors |
| 301+ | Very poor / Severe | Stay indoors as much as possible; keep reliever medicines ready |
Practical Protection That Actually Works
- Masks: a well-fitted N95 or FFP2 mask filters fine particles; cloth and surgical masks offer little protection against PM2.5.
- Timing: in winter, early mornings are often the most polluted. Many people do better walking in the late morning or afternoon, or indoors.
- At home: keep windows closed on high-AQI days, wet-mop instead of sweeping, avoid burning mosquito coils, agarbatti and sambrani in closed rooms.
- Air purifiers can help in a closed bedroom if sized correctly, but they do not replace medicines or doctor advice.
- Hydration and warm fluids soothe an irritated throat.
- Vaccination: an annual flu vaccine and, where advised, a pneumococcal vaccine reduce chest infections.

If You Already Use Inhalers
Winter is not the time to stop your controller inhaler because you "feel fine". Keep taking it exactly as prescribed, carry your reliever, and check your inhaler technique with your doctor — a surprising number of patients lose most of the dose through poor technique. If you have asthma or COPD, ask your chest specialist for a written action plan for bad-air days.
When to See a Chest Specialist in Tolichowki
If symptoms keep returning every winter, a simple lung function test (spirometry) and, when needed, a chest X-ray can show whether there is underlying asthma, COPD or another condition that needs proper treatment — rather than repeated cough syrups.
Frequently Asked Questions
Is a morning walk safe during Hyderabad's smog season?
On days when the AQI is poor or worse, early morning air is often the most polluted. People with asthma, COPD or heart disease should shift their walk to later in the day or exercise indoors, and check the AQI before stepping out.
Do masks help people with asthma in polluted air?
A well-fitted N95 or FFP2 mask reduces the fine particles you breathe in. Cloth and loose surgical masks offer little protection against PM2.5. If a mask makes you breathless, discuss it with your doctor.
Can air pollution cause a new lung disease?
Long-term exposure to polluted air is linked to reduced lung function, more chest infections and chronic lung disease, and it can unmask asthma in some adults. A persistent cough or breathlessness should always be evaluated.
Which test checks whether pollution has affected my lungs?
Spirometry, a simple breathing test, measures how well air moves in and out of your lungs. Your chest specialist may add a chest X-ray or other tests based on your symptoms.
