That tickle in your throat isn’t a cold
You don’t have a fever. You don’t feel sick. Yet every evening a dry, scratchy cough starts and won’t settle until you’re in bed. If you live in North India, there’s a good chance the culprit is the air, not a virus.
Delhi just recorded its most polluted first week of October since 2023, with an average AQI of 171, according to ThePrint. Stubble burning has begun, winter is coming, and air quality usually gets worse from here. This guide explains why pollution makes you cough, which Ayurvedic herbs have traditionally supported the lungs, and a simple daily routine to breathe easier this season.
Why pollution makes you cough
Fine particles (PM2.5) are small enough to travel deep into the airways. Your body treats them as invaders. The lining of the throat and bronchi becomes irritated, produces more mucus, and the cough reflex kicks in to clear it.
Common signs of a pollution cough:
-
Dry or tickly cough that is worse outdoors, in traffic or in the evening
-
Scratchy throat, frequent throat clearing
-
Mild chest tightness or breathlessness on walks
-
Watery eyes, sneezing and a blocked nose
-
No fever, and you don’t feel “ill”
In Ayurveda, this picture fits a mix of Vata (dryness, irritation) and Kapha (mucus, congestion) disturbing the pranavaha srotas, the channels that carry breath. Care focuses on soothing dryness, clearing excess mucus, and strengthening the lungs’ natural resilience.
5 Ayurvedic herbs that support the lungs
1. Vasaka (Adusa, Malabar nut). Vasaka is the classic Ayurvedic herb for cough and breathing. Its leaves contain vasicine, a compound studied for its effect on loosening mucus. It’s the base of many traditional cough formulations.
2. Mulethi (Licorice). Mulethi coats and soothes an irritated throat, which is why grandmothers handed you a stick to chew. It’s best suited to dry, scratchy cough. People with high blood pressure should use it only with medical advice, since large amounts can raise BP.
3. Tulsi (Holy basil). A daily herb in Indian homes for good reason. Tulsi is traditionally used to support immunity and clear the airways, and it pairs well with ginger in a warm tea.
4. Pippali (Long pepper). A warming herb used in small quantities to reduce Kapha and support the respiratory tract. It’s part of the classic trikatu blend.
5. Haldi (Turmeric). Curcumin is widely studied for calming inflammation. Warm turmeric milk at night is a gentle, familiar way to take it.
A daily lung-care routine for high-AQI days
Morning
-
Check the AQI before stepping out. Above 200, skip outdoor exercise.
-
Steam inhalation for 5 minutes, plain or with a few ajwain seeds.
-
Two rounds of anulom-vilom for 5 minutes, indoors.
During the day
-
Wear an N95 mask in traffic. Cloth masks don’t filter PM2.5.
-
Sip warm water instead of cold drinks. It keeps the throat moist.
-
Keep windows shut during peak hours (early morning and late evening).
Evening
-
Gargle with warm salt water after coming home.
-
Tulsi-ginger tea or turmeric milk.
-
Rinse your face and nostrils to remove settled dust.
What to eat in pollution season
-
Vitamin C foods: amla, guava, oranges and lemons help your body cope with oxidative stress.
-
Warm, cooked meals: soups, dal and khichdi are easier on a Kapha-heavy system than cold, raw food.
-
Jaggery in small amounts: traditionally believed to help clear dust from the throat.
-
Spices: ginger, black pepper, ajwain and garlic in daily cooking.
-
Avoid: fried snacks, ice-cold drinks and excess dairy at night if you already have mucus.
Pranayama for lungs in pollution season
Breathing exercises help, but do them indoors with clean air. Anulom-vilom, bhramari (humming bee breath) and slow deep belly breathing are gentle choices. Skip forceful kapalbhati if you’re actively coughing or feel chest tightness.
Ayurvedic support: choosing the right option
For many people, steam, warm water and a mask are enough. If your cough lingers through the season, a herbal supplement can be one more layer of support.
-
Malabar Nut Capsules are made from vasaka, the herb most closely linked with cough in Ayurveda.
-
Mulethi Capsules suit a dry, scratchy throat.
-
Breath More Capsules are a respiratory wellness blend for the season.
These support your routine; they don’t replace a mask, clean air or medical care. If you have asthma, keep using your inhaler and talk to your doctor before adding any supplement.
When a cough needs a doctor
See a doctor promptly if you have:
-
A cough lasting more than 3 weeks
-
Fever, body ache or yellow-green phlegm (it may be flu, including H1N1)
-
Blood in the phlegm
-
Wheezing, breathlessness at rest or chest pain
-
Asthma or COPD that is getting worse
Make your home a cleaner-air zone
We spend most of the day indoors, so a few changes at home make a real difference during high-AQI weeks:
-
Use an air purifier with a HEPA filter in the bedroom if you can. Keep the door closed while it runs.
-
Avoid agarbatti, dhoop and mosquito coils indoors on bad-air days. They add their own smoke and fine particles.
-
Wet-mop floors instead of dry sweeping, which throws dust back into the air.
-
Ventilate at the right time. Open windows for a short while in the afternoon, when outdoor air is usually less polluted than early morning or late evening.
-
Keep indoor plants as a bonus, not a solution. They’re pleasant, but they don’t clean air the way a purifier does.
-
Don’t smoke indoors, and ask guests not to. Second-hand smoke and pollution together are especially hard on children and older family members.
If someone at home has asthma, heart disease or is elderly, plan their outdoor time around the AQI forecast. On “severe” days, even a short morning walk outside can do more harm than good.
FAQs
Is pollution cough contagious? No. It’s an irritation response, not an infection. But if fever appears, an infection may have set in.
Can you detox your lungs? Your lungs clean themselves through mucus and tiny hair-like cilia. Herbs, steam and clean air support that process; no product “detoxes” lungs overnight.
How long does pollution cough last? It usually eases within days of cleaner air. If it continues for weeks, get checked.
Breathe a little easier this season
You can’t control the AQI, but you can control what happens at home. Start tonight: salt-water gargle, tulsi tea and five minutes of anulom-vilom. Share this with someone in your family who has been coughing since the weather changed.
