Smog Season in Lahore: Skin, Eyes, Masks and Indoor Air
From late October the Punjab sky goes flat and white, and half the country calls it fog. Most of it isn’t fog. Smog season is smoke and road dust pressed down by cold, still air, and your eyes, throat and skin register it days before you admit what you’re breathing.
The short version
- Change first: Your evening wash, and whether you’re wearing a mask that actually seals.
- Leave alone: Your moisturiser. Smog is not a reason to strip your skin back.
- Biggest win: The air inside your own rooms. You control that one.
- Who cannot treat this casually: Asthma, COPD, heart conditions, small children, older relatives, pregnancy.

What smog season actually does to skin, eyes and throat
The particles people worry about are the fine ones, the ones small enough to stay suspended and go deep into the lungs, which is the part a doctor actually cares about. On the surface, the effects are cruder. And more familiar.
Eyes go gritty and red by evening. Worse for anyone who drives a bike or waits at a stop. Throats get that dry scratch that isn’t quite a cold and doesn’t behave like one, because there’s no fever and it eases at home and returns on the road. Skin picks up a film of soot and traffic grime that you can see on a cotton pad, and the real problem isn’t the dirt itself but what people do about it. They scrub. Then the skin stings, so they use something soothing with fragrance in it, and by mid-December they’ve made a chemical irritation on top of an environmental one.
Smog season also sits on top of winter, so you get cold dry air, a gas heater indoors and a layer of particulate at once, and that combination is why lips crack faster in December. The heater is doing more of that damage than the smog is, and there’s a whole piece on why the heater is the real culprit in winter.
Swap this for that
| Stop | Start | Why |
|---|---|---|
| Scrubbing your face after a commute | A plain gentle cleanser, lukewarm water, 30 seconds | Soot sits on the surface. It lifts off. Scrubbing damages the barrier that keeps irritation out. |
| Washing your face only in the morning | Washing when you get home, whatever time that is | The point is to not sleep in a day’s worth of road film. |
| A cloth or surgical mask for pollution | A well fitted N95, KN95 or FFP2 | Only a sealed respirator is built to filter fine particles. Fit matters more than brand. |
| Rubbing itchy eyes | A rinse, then a cool compress for 5 minutes | Rubbing grinds grit across the surface of the eye and makes the redness worse. |
| Morning walks during the worst hours | Midday or early afternoon, when the layer lifts a bit | Smog is typically thickest overnight and at dawn, when cold air traps it near the ground. |
| Dry sweeping with a jhaaru | Damp mopping, and a damp cloth on surfaces | Dry sweeping lifts settled dust straight back into the air you’re breathing. |
| Agarbatti, coils and candles indoors on bad days | Nothing burning inside at all | Indoor smoke adds to the same particle load you shut the windows to avoid. |
Washing your face and rinsing your eyes properly
This is the whole routine. Three minutes. It replaces nothing else you do.
- Hands first. 20 seconds with soap. Everything after this involves touching your face, and your hands have been on a bike handle, a gate and a note from a shopkeeper.
- Rinse your face with lukewarm water, roughly body temperature, for 15 seconds before any cleanser. This carries off the loose grit so you aren’t rubbing it in.
- Cleanse with about half a teaspoon of a plain non-foaming or mildly foaming cleanser. 30 seconds of light circles with fingertips only. No brushes, no scrub, no ubtan on smog days.
- Rinse well and pat dry. Pat, don’t drag. A rough towel on wind-chapped skin undoes the gentle bit you just did.
- Moisturise within a minute, while skin is still slightly damp. A pea-sized amount for the face, more if your skin is dry. This is the step people skip because their skin feels dirty rather than dry, and it’s the step that stops the cycle.
- Eyes, if they’re gritty: splash 3 or 4 handfuls of clean cool water over closed lids, then hold a cold, clean cloth over them for 5 minutes. Preservative-free artificial tears from a pharmacy are fine to use as directed on the box. Do not rub.
- Throat, if it’s scratchy: a plain warm salt water gargle, quarter teaspoon of salt in a cup of warm water, twice a day. The proper gargling method is worth doing correctly rather than swilling and spitting.
Nose rinsing with saline helps some people and irritates others, and if you try it, use only sterile, distilled or previously boiled and cooled water, never straight tap water.
Masks: what works, what is theatre
| Mask | Against smog particles | The honest note |
|---|---|---|
| N95, KN95, FFP2 | The only real option | Works only with a seal. Both straps on, metal strip pinched to the nose bridge, no gap at the cheeks. |
| Surgical mask | Partial at best | Designed for droplets and splashes, loose at the sides. Better than nothing, not a pollution mask. |
| Cloth or fashion mask | Very little | It catches visible dust and gives you a feeling of doing something. That’s roughly the extent of it. |
| Muffler or dupatta over the face | Negligible for fine particles | Useful for cold and for grit in a dust storm. Not a filter. |
Three things decide whether a respirator is doing its job. It has to seal. A thick beard breaks that seal, and there’s no product fix for it. It has to be the right size, so an adult mask on a six year old is a gap with a mask attached. And it has to be breathable enough that you keep it on, because a mask pulled under the chin at the bazaar is filtering the inside of your kurta.
Replace a disposable respirator when it gets damp, dirty, misshapen or hard to breathe through. Don’t wash it. Washing destroys the filtering layer, whatever the video said.
Unani and Ayurvedic seasonal conduct both treat the cold months as a time for warm, oily, unctuous habits: steam, oil in the nose, warm drinks, covering the head and ears when going out. Nasya, a drop of oil in each nostril, is a traditional winter practice that many households still keep. None of it filters air. Read it as comfort and custom, not defence. The habit with real carryover is the old instinct to cover up and to come home, wash, and change clothes.
The air inside your house
You can’t fix Lahore’s air. You can make one or two rooms noticeably better, and that’s where the effort pays.
Keep windows shut through the worst of it, which is usually the overnight and early morning hours, and open up briefly when a local air quality reading improves, because a sealed room with a gas heater has its own problems. Check an AQI app for your own area rather than the city average; a reading in the unhealthy band or worse is the point at which outdoor exercise stops being a good idea for anyone.
Stop adding smoke indoors. Mosquito coils, agarbatti, a charcoal angeethi, cigarettes, all of it lands in the same lungs. If someone smokes, outside, door closed.
An air purifier with a true HEPA filter genuinely lowers particle levels in the room it’s sitting in, if it’s rated for roughly that room size and you actually run it with the door shut. Buy it for the bedroom, where you spend seven or eight unbroken hours in one place. Ionisers and ozone generators are a different category and are not a substitute for a HEPA filter. Can’t stretch to one? Damp mopping, doormats and shoes off at the door are free, and they help more than people expect.
You cannot filter a city. You can filter a bedroom.
Who has to take smog season seriously
For most healthy adults, smog season is a run of gritty eyes, a scratchy throat and a duller face. For the people below it isn’t a cosmetic season at all.
Asthma and COPD. Bad air weeks are when attacks cluster. Keep reliever inhalers filled, carried and in date, not in a drawer at home, and if you’re needing a reliever more often than usual, that’s a conversation with your doctor now rather than after a bad night.
Children. They breathe faster for their size and they’re outdoors more, so watch for a cough that lingers past a couple of weeks, wheeze, or breathlessness during normal play.
Older relatives and anyone with heart disease. Chest tightness, unusual breathlessness or palpitations during a bad spell are not something to wait out at home.
Pregnancy. Reason enough to prioritise the indoor air fixes and to skip the dawn walk during a bad stretch. Any breathing difficulty gets checked, not monitored.
Get medical help for breathing difficulty, chest tightness or pain, a wheeze that’s new, blue lips, confusion, or a child who is breathing fast, pulling in at the ribs or too breathless to finish a sentence. For eyes, see a doctor rather than a pharmacy for eye pain, any change in vision, sensitivity to light, a feeling that something is still stuck after rinsing, or discharge and swelling. A cough lasting more than three weeks, or any coughing of blood, needs proper assessment and not another kaadha.
One thing to do this week
Buy one packet of properly fitting N95 or KN95 masks and put them where you leave the house, not in a cupboard, then move the wash to the moment you get home. Two changes, no products bought, and they cover most of what you can control.
What else the cold months bring
Smog is only one of the winter and dry-season problems on the plains, and the other big one arrives in the pre-monsoon months, when the wind turns and the sky goes orange, and that’s a different set of rules for grit in your eyes and hair after an andhi. If your skin is also cracking and your heels are splitting, start with the winter dry skin routine instead of layering more on top. The rest of the year is mapped out on the Season Shift hub.
Do anti-pollution creams and serums work?
Treat the label as marketing. A plain cleanser and a decent moisturiser handle the visible part, and there’s no cream that stops particles reaching your lungs, which is the part that matters.
Can I reuse an N95 mask?
Yes, for a few outings, until it’s damp, dirty, stretched or harder to breathe through, and keep it in a paper bag rather than a plastic one between uses, never washing it.
Should children wear masks in smog season?
Only a properly sized child respirator is worth much, and very small children often won’t tolerate one, so the useful levers for them are avoiding the worst hours outdoors, clean indoor air at home, and not burning anything inside. Ask your paediatrician if your child has asthma.
Is my morning walk still a good idea?
Not in the dawn hours during a bad spell, when the layer sits lowest. Shift it to later in the day, or move it indoors, because exercise makes you breathe harder and deeper, which is exactly what you don’t want in heavy smog.
My eyes water and itch every evening in December. Is that smog or an allergy?
It can be either and often both, though smog irritation usually eases within an hour or two of being home in cleaner air. Itching that comes with sneezing and a runny nose in the same season each year leans allergic and is worth discussing with a doctor, since that has its own treatment.
