Ever inhaled deeply and thought, "Hmm, is oxygen supposed to taste crunchy?" Some cities turn breathing into an extreme sport, complete with smoggy skies and air thicker than grandma's oatmeal. Hold your breath—or maybe don't—as this article reveals a few cities where casually strolling could feel like smoking a pack of cigarettes.

This small but heavily industrialized town in India has an average PM2.5 level of 128.2 µg/m³—more than 25 times the World Health Organization's recommended limit. Coal-fired factories, cement plants, and chemical industries pump toxic particles into the sky. Locals are used to the smog, but it's a choking experience for outsiders.

Anyone who's been to Delhi knows the routine full of smog masks, eye-watering air, and news reports urging people to stay inside. Its average PM2.5 level of 108.3 µg/m³ makes it a smoke chamber in the winter. On bad days, the air smells like a campfire—except it's not the kind you'd want to roast marshmallows over.

Karaganda's air is thick enough to chew. It was once a central coal-mining hub, and still relies on coal for heat and electricity. This results in permanent haze that leaves streets, homes, and lungs coated in soot. PM2.5 levels hover around 104.8 µg/m³, so fresh air is rare.

This Pakistani city often competes with Delhi for the "most polluted major city" title at PM2.5 levels, hitting 102.1 µg/m³. The main culprits are brick kilns, unregulated industrial emissions, and relentless traffic. The problem worsens in winter when temperature inversions trap pollutants near the ground.

Sitting next to Delhi, this industrial hub pumps out smoke and dust like it's part of the economy. PM2.5 levels reach an unhealthy 101.2 µg/m³, thanks to relentless construction, unfiltered factory emissions, and never-ending traffic. People here have adapted to the pollution, but visitors often leave with itchy eyes and a sore throat.

N'Djamena's pollution problem is all about the dust, with PM2.5 levels averaging 91.8 µg/m³. Sahara winds sweep in fine particles that coat everything they touch, including your lungs. The place is also full of vehicle emissions and open-air cooking, which makes the air more suffocating.
Hotan, China

Hotan's air pollution is from the desert itself. The city sits on the edge of the Taklamakan Desert, and the wind loves to carry sand straight into town. PM2.5 levels get ridiculously high, especially when industrial pollution joins the mix. Thus, face masks are necessary for keeping the grit out of your lungs.
Dhaka, Bangladesh

Dhaka is booming, but so is its pollution problem. The thick air makes short walks feel exhausting. If you opt for a car, the traffic is endless, and most vehicles produce black fumes. There's no real escape because, even indoors, air purifiers are a must. Its rapid expansion is impressive, but at what cost?
Ulaanbaatar, Mongolia

If you ever wanted to live in a chimney, Ulaanbaatar might be the best option. Every winter, it practically becomes a pollution capital. Thousands of families burn coal to keep warm, which results in a toxic fog that blankets the city, and pushes PM2.5 levels to extreme highs.
Kampala, Uganda

Traffic congestion is legendary in Kampala, with cars, motorcycles, and minibus taxis belching out thick plumes of black exhaust. The roads are dusty, unpaved, and filled with constant construction debris. It's made worse by its own location—it is low-lying and prone to trapping bad air.
Manama, Bahrain

Manama combines desert dust, car fumes, and oil refinery emissions. The city's rapid growth meant more vehicles, construction, and development but left residents stuck in a cloud of fine dust and exhaust. Some say the skyline looks dreamy at night, but the air is a total nightmare!
Hanoi, Vietnam

Hanoi was once crowned the "most polluted city in the world." With rising tourism growth, its air has become a thick soup of exhaust fumes, construction dust, and factory emissions. On some days, the city skyline disappears behind a wall of gray.
Phnom Penh, Cambodia

Phnom Penh is expanding fast, and so is its pollution problem. Dust from construction sites coats the streets while endless traffic jams spew out thick exhaust, not to mention the lack of minimal green spaces that are supposed to absorb pollution.
Jahra, Kuwait

Jahra is choking with its mix of desert dust, oil refinery emissions, and heavy traffic fumes. PM2.5 levels regularly soar, and sandstorms only make things worse. The sunsets here might be stunning, but the haze that gives them that dramatic glow is all dust and pollution settling in for the night.
Guangzhou, China

Guangzhou has tried to clean its air, but it's still far from fresh. This massive industrial hub in southern China has long battled smog from factories, construction, and relentless traffic. Even after China's crackdown on coal and emissions, Guangzhou still struggles with PM2.5 levels that regularly hit dangerous highs.
