Diwali Smoke and Asthma: A Night Plan for Kids and Lungs
Diwali smoke carries fine particles, and children and anyone with asthma are the people most likely to feel it first. This guide gives you a timeline for three windows: the hours before the first cracker, the night itself and the morning after. It also lists the signs that mean a doctor, not a home fix.
At a glance
- Most at risk: young children and people with asthma, plus anyone with another breathing condition.
- Before the crackers: pick the least smoky room and keep the written asthma plan and any reliever within reach.
- Morning after: wet-clean the sills, doors and floors before you sweep or vacuum.
- Rule of thumb: set up the safe room before the first cracker, not after the first cough.

Why does Diwali smoke reach the lungs so easily?
Firecracker smoke carries gases and very small particles, and the particles are the part that matters most for breathing. The World Health Organization says exposure to fine particulate matter causes respiratory and cardiovascular disease, which is why a smoky night deserves a plan rather than a shrug. Smoke can also drift in through gaps around windows and settle on curtains, bedding and floors, so a room may feel worse as the night goes on. To read the number on your air quality app, see what AQI numbers mean. Incense and cooking smoke are a separate everyday problem, and our indoor air pollution guide ranks them.
Who needs the most care on Diwali night?
The World Health Organization calls air pollution one of the greatest environmental risks to child health, so children come first in any plan. The NHS lists air pollution, cold air, dust, pollen, mould, infections and exercise among common asthma triggers. If anyone at home has asthma, smoke belongs in their written plan rather than being left to chance. Pregnant women with asthma or other breathing problems should check with their doctor before the festival week, not on the night itself.

What should you set up before the first cracker?
- Find the asthma plan and the reliever. If anyone has asthma, take out the written plan and the reliever inhaler, check the inhaler is in date, and put both where a child or older relative can reach them without help.
- Choose the safe room. Pick the room furthest from the front door, balcony and street-facing windows, and shut its windows and door before the crackers start.
- Move people in early. Bring children and older relatives into that room before the loudest hour, rather than waiting for the first cough to make the decision for you.
- Stock the basics. Keep a jug of clean drinking water, wet wipes, a clean cloth and tissues in the room, so nobody has to walk through the smoke to get them.
- Agree one signal. Pick a short phrase everyone knows, such as “chest feels tight”, so a child can say it without stopping the fun.
Diwali night is not one event, and the risk changes across the evening. Keep this table in mind, because each window has one job.
| When | What to do | Why it matters |
|---|---|---|
| Crackers starting | Stay in the safe room with the door shut | Keeps outside smoke out as far as one room can |
| Peak hour | Check breathing, colour and talking, not just whether a child is quiet | A quiet child with fast breathing needs help |
| Late night | Use the reliever only as the written plan says | Guessing the amount is how mistakes happen |
| Morning after | Wet-clean first, then ventilate | Stirred-up dust makes the air worse until it settles |
How do you clean up the morning after without stirring more dust?
Clean-up order matters more than how hard you scrub. Kaiser Permanente notes that dusting and vacuuming stir up dust and make the air worse until the dust settles, so the wet work comes first and the dry work comes last.
- Let the smoke thin. Once the crackers have stopped and the air has calmed, air the room. Where you have it, air conditioning is the option Kaiser Permanente suggests in place of opening windows.
- Wet-wipe the sills, door frames and switches. Work from the top of each surface downwards, and rinse the cloth often.
- Damp-mop the floors. Use plain water. Kaiser Permanente also recommends damp-mopping hard floors once a day as a routine.
- Wash what smells of smoke. Curtains, cushion covers and bedding that hung near the window are better washed than shaken out indoors.
- Clean up the face and hands. Use clean water. If your eyes sting, rinse them with clean water and do not rub, and see the eye injury first steps guide if anything gets in them.
- Wash hands before food. Smoke residue sticks to hands, and children touch everything before a meal.
Insider tip: wet-clean before you sweep
Anything that settled overnight can be lifted again by dry cleaning, which is why wiping and damp-mopping come first. If you use a vacuum, choose one with a HEPA filter or a double-thickness bag, because a standard paper bag may let stirred-up particles escape back into the room.
When does smoke need a doctor, not a home fix?
Medicines for children depend on age and weight, and some products are not for small children at all. This table gives five age bands, each with its own rule.
| Age band | Keep away from | Medicine rule |
|---|---|---|
| Under 6 months | Smoke, incense, camphor and Vicks | Feed as usual; no cough or cold medicine without a doctor or pharmacist; a temperature of 38C or higher needs a call to NHS 111 the same day |
| 6 to 12 months | Smoky rooms, camphor, Vicks and mustard oil rubs | No honey under 1 year; ask a pharmacist before any cough or cold medicine |
| 1 to 3 years | Smoky rooms, camphor, Vicks, menthol and eucalyptus | Some cough and cold medicines are not for children under 12, so check the pack or ask a pharmacist; pain relief by weight, from the pack or a pharmacist |
| 3 to 6 years | Smoky rooms and crackers held near the face | Some cough and cold medicines are not for children under 12, so check the pack or ask a pharmacist; pain relief by weight, from the pack or a pharmacist |
| Over 6 | Smoky rooms and tobacco smoke | Ask a pharmacist before any cough medicine, and follow the asthma plan |
Call 999 now if breathing is difficult, if the person gets worse at any time, if they do not improve on their reliever, or if they have no inhaler. The NHS says an asthma attack can be life-threatening, so do not wait. Do not drive yourself to A&E. A temperature of 38C or higher in a baby under 3 months needs a call to NHS 111 the same day, and a high temperature that has lasted 5 days or more should be checked by a doctor. Pregnant women who feel breathless, dizzy or have chest pain should get same-day medical advice. Never work out a painkiller amount from memory: use the pack or ask a pharmacist, going by the child’s weight.

Questions parents ask about Diwali smoke
Can Diwali smoke set off asthma?
Yes. The NHS lists air pollution and cold air among common asthma triggers, so a smoky night can bring on symptoms in someone who already has asthma. Follow the written asthma plan, keep the reliever close, and call 999 if breathing gets worse.
Is Diwali smoke harmful during pregnancy?
It can be a concern, especially for anyone with asthma or another breathing condition. Stay in the cleanest room you can, and check with your doctor before the festival week. Get same-day advice if you feel breathless, dizzy or have chest pain.
What should I do if a child coughs after the crackers?
Move the child to the cleanest room, sit them up straight to help their breathing, and watch their breathing and colour. Follow the written asthma plan if there is one. Difficult breathing needs emergency help now, not a wait to see.
Can I rub Vicks or camphor on a child’s chest?
Ask a pharmacist first, and keep camphor, Vicks, menthol and eucalyptus products away from a baby’s face. Some cough and cold medicines are not for children under 12, so check the pack before giving any of them. Fluids, a calm room and a call to the pharmacist are the safer steps.
Should windows stay shut on Diwali night?
Keep the windows shut while the smoke is heavy, especially in the room where children are sleeping. Once the crackers stop and the air is calmer, air the room, using air conditioning instead of opening windows if you have it, and then clean.
Do children need a mask on Diwali night?
A mask only helps when it fits well, and children’s sizes differ from adult ones. Read our N95 and mask guide for fit and reuse before you buy anything. A mask is never a reason to stay outside in the smoke.
What if smoke makes a child’s eyes sting?
Rinse the eyes with clean water that is not hot, and do not rub them. If something is in the eye, wash it out with clean water. Get urgent advice from a GP or NHS 111 if the eye is still painful or not better after 24 hours, and go to A&E or call 999 for any change to sight. The eye injury guide covers the first steps in more detail.
Can a baby under 6 months cough after Diwali smoke?
A baby with difficult breathing needs emergency help now, and a temperature of 38C or higher under 3 months needs a call to NHS 111 the same day. A cough that keeps going needs a doctor to look at it. Keep the baby out of the smoke and feed as usual. Do not give honey, which is not suitable under 1 year, and ask a doctor or pharmacist before giving gripe water, herbal drops or any cough remedy.
How should I use an asthma reliever on Diwali night?
Use it the way the written asthma plan says, and ask the doctor or pharmacist for the amount if the plan is unclear. This article does not give medicine amounts. If the reliever does not help, call emergency services.
