If you woke up in Dhaka this morning, you probably didn't see the sun. Not really. What you saw was a dull, orange-grey disc struggling to pierce through a thick, heavy blanket of smog. It’s January 2026, and the city is once again gasping for air.
Honestly, it’s getting hard to breathe.
Just a few days ago, on January 16, Dhaka hit a staggering Air Quality Index (AQI) of 273. That’s "very unhealthy." For three days straight, this city sat right at the top of the global list for the worst air on the planet. Worse than Delhi. Worse than Karachi. Surpassing every other megacity in a race no one wants to win.
Basically, breathing the air here right now is the physiological equivalent of smoking nearly five cigarettes a day. Imagine that. Even if you’ve never touched a tobacco leaf in your life, your lungs are paying the price of the city’s growth.
Why Dhaka Bangladesh Air Pollution Hits So Hard in Winter
You’ve probably noticed that the air feels "crunchy" in the winter. There's a scientific reason for that. It’s not just that there’s more smoke; it’s that the smoke has nowhere to go. During these dry months, we get what meteorologists call a temperature inversion. Cold air gets trapped near the ground by a layer of warmer air above it. It acts like a lid on a pot. Everything we produce—truck exhaust, brick kiln smoke, construction dust—just stays right here at eye level.
The Brick Kiln Problem
The geography of the pollution is fascinating, if a bit terrifying. Take Savar. In August 2025, the government officially declared Savar a "degraded air shed." They banned brick kilns. They said the burning had to stop.
But have you been out there lately?
Reports from earlier this week show that many kilns are still firing away. As of June 2025, there were 86 kilns in Savar alone. Whether they have a license or not, they’re still pumping out black clouds. When the wind blows from the north, all that particulate matter drifts straight into the heart of Dhaka. It’s a direct pipeline of toxins.

The Unseen Killers: PM2.5 and PM10
We talk about "dust," but what we’re really dealing with is PM2.5. These are tiny particles, less than 2.5 micrometers in diameter. They’re so small they don't just sit in your lungs; they cross into your bloodstream.
Recent studies from 2025, like the one published in Radiology by researcher Du Plessis, found something scary. Long-term exposure to Dhaka’s air is causing diffuse myocardial fibrosis. That’s a fancy way of saying your heart muscle is scarring. The heart gets stiff. It can’t pump.
- Heart Disease: Pollution is now linked to nearly 30,000 heart-disease deaths in Bangladesh every year.
- The "Hidden" Epidemic: We often think of lung cancer, but stroke and ischemic heart disease (heart attacks) are actually the bigger killers here.
- Children at Risk: Over 5,000 kids under five die annually from pneumonia caused by these particles.
It’s not just "a cough" anymore. It's a cardiovascular crisis.
What Most People Get Wrong About the Sources
People love to blame the old buses. And yeah, those black-smoke-belching "murir tin" buses are part of the problem. They account for about 15% of the mess. But if we only fixed the buses, we’d still be in trouble.
Did you know that transboundary pollution accounts for roughly 40% of our air issues? A lot of the coal-burning smoke from across the border in India and even as far as Nepal drifts right over us. We’re literally breathing in the industrial output of our neighbors.
Then there’s the construction. Dhaka is a city that never stops building. Unplanned road excavations and massive infrastructure projects contribute nearly 30% of the local pollution. If you live near a "Mega Project," you’re likely breathing in double the dust of someone in a quieter neighborhood.
The Neighborhood Map: Where is it Worst?
It’s not the same everywhere. On January 17, 2026, the data showed some wild differences across the city.

Nikunja (ASL Systems area) recorded a hazardous 449. That is off the charts. Dhanmondi wasn't far behind at 362. Meanwhile, South Pallabi hit 346. These are numbers that should keep everyone indoors. If you’re living in these pockets, your "fresh air" is actually a toxic soup.
On the flip side, some areas like Eastern Housing were sitting at 299. Still "very unhealthy," but technically better. It’s a strange reality where "less toxic" feels like a win.
The Government’s New Plan: Will It Work?
Just yesterday, January 17, 2026, Environment Adviser Syeda Rizwana Hasan launched the National Air Quality Management Action Plan.
It sounds promising. They’re talking about:
- Automation: A new software system to stop the "under the table" environmental clearances for factories.
- Strict Enforcement: Actually shutting down those Savar brick kilns that keep defying orders.
- Traffic Management: Reducing the time cars sit idling in gridlock, which is a massive (and preventable) source of NO2.
But we’ve had plans before. The 2022 Air Pollution Control Rules were supposed to fix this. The reality is that enforcement is hard when the city is growing this fast.
Actionable Steps: How to Live in Dhaka Right Now
You can’t wait for a five-year government plan to catch your next breath. Here is what the experts (and the current data) suggest you do immediately.
Get the Right Mask
Stop using those thin blue surgical masks. They do almost nothing for PM2.5. They’re designed for droplets, not microscopic soot. You need an N95 or FFP2 mask. It needs to seal against your face. If air is leaking in through the sides, you’re just wasting your money.

Monitor the "Pulse" of the Air
Don't just look out the window. Check real-time apps like IQAir or the Department of Environment’s portal. If the AQI is over 200, do not go for a morning run. You’re just pumping toxins into your lungs faster. Exercise indoors.
Seal Your Home
It sounds extreme, but during the winter peak (December to February), keep your windows shut. Use heavy curtains. If you can afford it, an air purifier with a HEPA filter is no longer a luxury in Dhaka; it’s a medical necessity. Focus on the bedroom first—you spend 8 hours there breathing that air.
Change Your Commute
If you're in a rickshaw or a CNG, you're at the exhaust level of the trucks next to you. If you have to travel during peak hours, try to use vehicles with filtered air systems, or at the very least, keep your N95 mask on the entire time you're on the road.
The situation with Dhaka Bangladesh air pollution isn't going to vanish overnight. It’s a complex mix of local greed, regional weather, and the growing pains of a developing nation. But knowing the numbers—and knowing that the "fog" you see is actually a health hazard—is the first step toward staying safe.
Keep your masks tight and your windows closed. It's going to be a long winter.
Next Steps for Protection:
- Check your local AQI every morning before leaving the house.
- Ensure your office or home has functional ventilation that doesn't just pull in outside smog.
- Replace your N95 masks every few days; once they get clogged with Dhaka's heavy dust, they lose their effectiveness.
