The temperature drops, but the air turns thick with smoke. India\u2019s capital, Delhi, loses its sharpness \u2013 its colours and contrast. The sky turns grey, as people wheeze through their lives, left with little option but to feign normalcy. But the headlines scream another story \u2013 some say the city is \u201c<a href=\"https:\/\/www.thehindu.com\/news\/cities\/Delhi\/delhi-chokes-on-toxic-smog-air-quality-panel-flags-recurring-negligence-high-dust-levels\/article70396816.ece\">choking<\/a>\u201d, its air \u201c<a href=\"https:\/\/aninews.in\/news\/national\/general-news\/despite-marginal-improvements-delhis-air-remains-unbreathable-at-397-aqi20260120082742\/\">unbreathable<\/a>\u201d, while others call it a \u201c<a href=\"https:\/\/www.ndtv.com\/delhi-news\/delhi-ncr-remains-a-gas-chamber-as-aqi-crosses-400-mark-9639675\">gas chamber<\/a>\u201d. A 2024 Lancet <a href=\"https:\/\/www.thelancet.com\/journals\/lanplh\/article\/PIIS2542-5196%2824%2900114-1\/fulltext\">study<\/a> argues that 12,000 deaths in the city can be attributed to air pollution annually, while an analysis by the Washington Post last month equates Delhi\u2019s average daily air quality to <a href=\"https:\/\/www.washingtonpost.com\/world\/2026\/01\/25\/india-pollution-winter-toxic-air\/\">smoking<\/a> nine cigarettes a day.<\/p>\n\n\n\n<p>This is winter in one of the world\u2019s biggest cities, with a population upwards of <a href=\"https:\/\/population.un.org\/wup\/assets\/Publications\/undesa_pd_2025_wup2025_summary_of_results_final.pdf\">30 million<\/a>. And yet, not everyone among those 30 million people experiences winter the same way.<\/p>\n\n\n\n<p>It is early December in Okhla, a neighbourhood in south-east Delhi, and 49 year old Sunita Kumari walks to the construction site where she works as a labourer. This is the fourth day the sun has made no appearance \u2013 not because of clouds or rain, but due to the pollution that refuses to let it shine through. On the day Kumari spoke to Dialogue Earth, the air quality index (AQI) reading for Okhla on <a href=\"https:\/\/www.aqi.in\/uk\/dashboard\/india\/delhi\/new-delhi\/okhla-industrial-estate\">aqi.in<\/a>, which collects data from private AQI meters installed across India, was 600. Most official AQI scales, such as those in India and the US, <a href=\"https:\/\/www.bbc.co.uk\/news\/articles\/ced6jgg0180o\">cap out<\/a> at 500.<\/p>\n\n\n\n<p>Her body heaves with a persistent, heavy cough that has bothered her for years. If she breathes deeply, she can feel her lungs ache. \u201cIt has been this way since I remember. So whatever damage [to health] will happen, we are well past that stage,\u201d said Kumari, who was born and raised in the capital.<\/p>\n\n\n\n<p>Delhi\u2019s severe winter air pollution is attributable to a mix of geographical and local factors: <a href=\"https:\/\/www.outlookbusiness.com\/planet\/climate\/delhi-toxic-smog-crop-burning-surge-air-quality\">crop-residue burning<\/a> in neighbouring states, vehicular and industrial emissions, construction dust, waste burning and <a href=\"https:\/\/www.bbc.co.uk\/news\/articles\/cy8vxl0k15ro\">Diwali firecrackers<\/a>. These factors are <a href=\"https:\/\/www.ceh.ac.uk\/news-and-media\/blogs\/measuring-and-tackling-air-pollution-delhi\">compounded<\/a> by stagnant winds and temperature inversions that trap pollutants near the ground, creating a lethal cocktail that has led many to consider Delhi the most polluted capital in the <a href=\"https:\/\/www.iqair.com\/newsroom\/december-15-2025-delhi-among-top-10-most-polluted-cities-in-the-world\">world<\/a>.<\/p>\n\n\n\n<p>While pollution in the air is all pervasive, there are some who are finding ways to adapt \u2013 such as through the purchase of <a href=\"https:\/\/www.fortuneindia.com\/business-news\/toxic-air-drives-surge-in-air-purifier-sales-across-delhi-ncr\/127884\">air purifiers<\/a>. But for most lower-income Delhi residents, there are multiple exacerbating factors that make winter particularly harsh, and these must form the core of urban planning in the city, experts tell Dialogue Earth.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-street-level-exposure\">Street-level exposure<\/h2>\n\n\n\n<p>Gufran Beig is a meteorologist and the founder and former project director of System of Air Quality Forecasting and Research (Safar), an Indian government <a href=\"https:\/\/www.indiascienceandtechnology.gov.in\/node\/111168\">initiative<\/a> that provides real-time, location-specific air quality information and forecasts for major Indian cities. With air pollution, he says, what matters when it comes to health deterioration is exposure: the pollution in the air one is in contact with.<\/p>\n\n\n\n<p>Indoors, exposure can be reduced when homes and offices are fitted with multiple air purifiers that run continuously, with their filters regularly changed and users staying in rooms <a href=\"https:\/\/www.news18.com\/lifestyle\/can-air-purifiers-really-help-in-delhis-hazardous-pollution-experts-weigh-in-9123779.html\">sealed<\/a> to prevent air leakage. <\/p>\n\n\n\n<p>But an air purifier is itself a luxury, as is the ability to stay home continually in a room \u2013 one that few can afford. In November, the Hindustan Times published a <a href=\"https:\/\/www.hindustantimes.com\/technology\/5-best-air-purifiers-to-survive-delhi-s-worst-aqi-days-what-really-works-for-air-pollution-in-2025-101762255587196.html\">list<\/a> of five air purifiers to survive Delhi\u2019s worst AQI days with, at a cost of between INR 18,000 to INR 28,000 (USD 196-305). The nominal GDP per capita in India in 2024 was <a href=\"https:\/\/data.worldbank.org\/indicator\/NY.GDP.PCAP.CD?locations=IN\">USD 2,700<\/a> a year. &nbsp;<\/p>\n\n\n\n<p>The Delhi state government has faced criticism for reportedly <a href=\"https:\/\/www.independent.co.uk\/asia\/india\/delhi-air-pollution-purifier-rekha-gupta-aap-b2852834.html\">purchasing<\/a> air purifiers for its own offices, even as it struggles to design policy to combat air pollution.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.wiego.org\/research-library-publications\/covid-19-crisis-and-informal-economy-delhi-india-continued-economic-impact-and-uneven\/\">Over 80%<\/a> of Delhi\u2019s workforce is comprised of informal workers, most of whom work outdoor jobs much like Kumari, according to a report from the labour research policy network Wiego. A 2023 <a href=\"https:\/\/idronline.org\/wp-content\/uploads\/2023\/08\/Chintan_UnfairReport_compressed.pdf\">report<\/a> from environmental research NGO Chintan found that of 400 participants studied across three types of informal workers in Delhi, 97% of <em>safai karamcharis<\/em> (individuals involved in public sanitation work), 95% of wastepickers, and 82% of security guards reported exposure to air pollution while working.<\/p>\n\n\n\n<div class=\"wp-block-cd-article-image aligncenter block--article-image block--article-image--article\" itemscope itemtype=\"http:\/\/schema.org\/ImageObject\"><div class=\"block--article-image__column\"><div class=\"hide-expand block--article-image__image\"><img class=\"lazy\" data-src=\"https:\/\/dialogue.earth\/content\/uploads\/2026\/01\/Sarojini-Nagar-construction-site-dust_Alamy_3D2YP46-1.jpg\" data-srcset=\"https:\/\/dialogue.earth\/content\/uploads\/2026\/01\/Sarojini-Nagar-construction-site-dust_Alamy_3D2YP46-1-768x512.jpg 768w, https:\/\/dialogue.earth\/content\/uploads\/2026\/01\/Sarojini-Nagar-construction-site-dust_Alamy_3D2YP46-1-1024x683.jpg 1024w, https:\/\/dialogue.earth\/content\/uploads\/2026\/01\/Sarojini-Nagar-construction-site-dust_Alamy_3D2YP46-1.jpg 2560w\" data-sizes=\"(max-width: 600px) 768px, (max-width: 1024px) 1024px, 2560px\" alt=\"woman sweeping dusty street\"\/><\/div><div class=\"block--article-image__content\"><div itemprop=\"caption\" class=\"block--article-image__caption\">A worker sweeps dust at a construction site in Sarojini Nagar, south-west Delhi, in November 2025 (Image: Raj K Raj \/ Hindustan Times\u00a0\/ Alamy)<\/div><\/div><\/div><meta itemprop=\"contentUrl\" content=\"https:\/\/dialogue.earth\/content\/uploads\/2026\/01\/Sarojini-Nagar-construction-site-dust_Alamy_3D2YP46-1.jpg\"\/><meta itemprop=\"contentSize\" content=\"2 MB\"\/><meta itemprop=\"height\" content=\"1707\"\/><meta itemprop=\"width\" content=\"2560\"\/><meta itemprop=\"author\"\/><meta itemprop=\"representativeOfPage\" content=\"true\"\/><\/div>\n\n\n\n<p>The Chintan report noted that between 30-60% of each group of workers were unaware that personal protective equipment (PPE) kits could reduce exposure, and nearly half of the wastepickers, 5% of <em>safai karamcharis<\/em> and 9% of security guards reported burning wood or coal for heat during winter. Abnormal pulmonary function results were recorded in 86% of <em>safai karamcharis<\/em> and security guards, as well as 75% of wastepickers. Women participants of all groups studied had poorer lung function than the men, it stated.<br><br>Not only do many lower-income Delhiites work outdoors, over 77% of the urban poor walk to work, <a href=\"https:\/\/dda.gov.in\/sites\/default\/files\/planning%20files\/Draft%20Policy%20for%20Enhancing%20Walkability%20in%20Delhi%20(English)11032019.pdf\">noted<\/a> the Delhi Development Authority in 2019, meaning they are more likely to inhale harmful pollutants. A 2015 <a href=\"https:\/\/urbanemissions.info\/wp-content\/uploads\/docs\/2015-12-AE-Delhi-On-Road-Exposures.pdf\">study<\/a> in Atmospheric Environment showed that walking on Delhi\u2019s roads resulted in PM2.5 concentrations \u201cexceed[ing] the ambient measurements by an average of 40%\u201d. This was higher than non-active transport such as cars and auto-rickshaws due to lower travel speeds and higher inhalation rates, it stated. Meanwhile, for air-conditioned cars, concentrations were halved.<\/p>\n\n\n\n<p>Women are particularly hard hit by these factors \u2013 a World Bank <a href=\"https:\/\/www.worldbank.org\/en\/news\/press-release\/2022\/12\/08\/new-world-bank-toolkit-to-make-transport-and-public-spaces-in-india-more-gender-inclusive#:~:text=How%20men%20and%20women%20travel%20is%20also,to%20consider%20affordability%20into%20account%20when%20travelling.\">report<\/a> estimated that 45% of women walk compared to 27% of men, often choosing this option for financial reasons.<\/p>\n\n\n\n<p>Bhaumik Gowande, a researcher at the non-profit International Council on Clean Transportation, argues that these factors are exacerbated by local infrastructure in low-income neighbourhoods in the city like Okhla, where Kumari lives and works. In these built up former urban villages or peripheral regions, \u201cyou\u2019ll find extremely dense cluster housing, where houses \u2013 a mix of high and low rises \u2013 develop in close proximity to each other. Some were illegal, some were later legalised,\u201d he notes, \u201cand the streets are so narrow that even a\u2026 minibus cannot pass through them\u201d.<\/p>\n\n\n\n<p>Instead, auto-rickshaws ply these streets. They pass close to homes in narrow cheek-by-jowl lanes, where most doors open directly onto the streets, Gowande says. Residents and commuters are constantly exposed to exhaust and tailpipe emissions from these vehicles, with a 2025 <a href=\"https:\/\/www.researchgate.net\/publication\/399137333_An_evaluation_of_commuter's_perception_of_exposure_to_air_pollution_on_a_segment_of_Delhi_Metro's_Magenta_line\">study<\/a> showing that auto-rickshaw commuters had the highest level of PM2.5 emissions at 113 micrograms per cubic metre \u2013 nearly 40% higher than the next most exposed mode of vehicular transport, cars with their windows down.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-exposure-at-home\">Exposure at home<\/h2>\n\n\n\n<p>It isn\u2019t just outdoors where pollution thrives in Delhi.<\/p>\n\n\n\n<p>Experts told Dialogue Earth that the lived realities for the city\u2019s lower income groups include added exposure to pollution inside their very homes.<\/p>\n\n\n\n<p>\u201cIn slum areas where people use wood, charcoal, kerosene, or similar fuels [for cooking and heating], the exposure due to indoor air pollution is very high,\u201d Beig said. These fuel sources release pollutants such as PM2.5, carbon monoxide and nitrogen dioxide within enclosed spaces \u2013 pollutants that are known to <a href=\"https:\/\/www.unep.org\/news-and-stories\/story\/seven-things-you-should-know-about-household-air-pollution#:~:text=They%20are%20terrible%20for%20human,outdoor%20air%20pollution%20every%20year.\">cause<\/a> stroke, heart disease and lung cancer, amongst other deadly illnesses.<\/p>\n\n\n\n<p>Here, too, women find themselves disproportionately affected, with responsibility for domestic duties largely on their shoulders. India\u2019s 2024 national Time Use Survey <a href=\"https:\/\/www.pib.gov.in\/PressReleasePage.aspx?PRID=2106113&amp;reg=3&amp;lang=2\">stated<\/a> that an average woman spends 289 minutes on unpaid domestic services for household members, including cooking \u2013 over three times that spent by men, at 88 minutes.<\/p>\n\n\n\n<p>Identifying this as a problem, the Indian government launched a <a href=\"https:\/\/www.pmuy.gov.in\/about.html\">scheme<\/a> in 2016 distributing liquefied petroleum gas (LPG) connections to women from families below the poverty line. But the use and refill of these cylinders <a href=\"https:\/\/thefederal.com\/category\/news\/ujjawala-scheme-parliamentary-panel-recommends-higher-lpg-subsidy-201808\">remain low<\/a> due to reasons including lack of affordability. \u201cFamilies use LPG only for special occasions, such as weddings or social visits, while daily cooking continues with traditional fuels,\u201d said Beig, who also teaches at the Indian Institute of Science in Bengaluru.<\/p>\n\n\n\n<p>A 2021 <a href=\"https:\/\/environment.yale.edu\/news\/article\/study-finds-poor-households-in-india-bear-brunt-of-pollution-effects\">study<\/a> on the impact of pollution on people of different income levels in India showed that low-income households face the brunt of all pollution sources. \u201cNot only do they suffer indoor air pollution from their own cooking, but they also face a disproportionate share of mortality risks from AAP [ambient air pollution], including from electricity generation and other industries to which their consumption contributes relatively little,\u201d it noted.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-clearing-the-air\">Clearing the air<\/h2>\n\n\n\n<p>While India waits for both concerted policy changes that tackle pollution, and attitude shifts when it comes to low-income neighbourhoods, experts believe there are small urban planning fixes that could bring relief.<\/p>\n\n\n\n<div class=\"wp-block-cd-article-image aligncenter block--article-image block--article-image--article\" itemscope itemtype=\"http:\/\/schema.org\/ImageObject\"><div class=\"block--article-image__column\"><div class=\"hide-expand block--article-image__image\"><img class=\"lazy\" data-src=\"https:\/\/dialogue.earth\/content\/uploads\/2026\/01\/Kartavya-Path-water-tanker_Alamy_3DCC1YB.jpg\" data-srcset=\"https:\/\/dialogue.earth\/content\/uploads\/2026\/01\/Kartavya-Path-water-tanker_Alamy_3DCC1YB-768x491.jpg 768w, https:\/\/dialogue.earth\/content\/uploads\/2026\/01\/Kartavya-Path-water-tanker_Alamy_3DCC1YB-1024x655.jpg 1024w, https:\/\/dialogue.earth\/content\/uploads\/2026\/01\/Kartavya-Path-water-tanker_Alamy_3DCC1YB.jpg 2560w\" data-sizes=\"(max-width: 600px) 768px, (max-width: 1024px) 1024px, 2560px\" alt=\"truck spraying water onto path\"\/><\/div><div class=\"block--article-image__content\"><div itemprop=\"caption\" class=\"block--article-image__caption\">A tanker operator sprays the Kartavya Path in central Delhi with water as part of the city\u2019s efforts to curb air pollution in December 2025 (Image: IMAGO \/ Hindustan Times \/ Alamy)<\/div><\/div><\/div><meta itemprop=\"contentUrl\" content=\"https:\/\/dialogue.earth\/content\/uploads\/2026\/01\/Kartavya-Path-water-tanker_Alamy_3DCC1YB.jpg\"\/><meta itemprop=\"contentSize\" content=\"2 MB\"\/><meta itemprop=\"height\" content=\"1637\"\/><meta itemprop=\"width\" content=\"2560\"\/><meta itemprop=\"author\"\/><meta itemprop=\"representativeOfPage\" content=\"true\"\/><\/div>\n\n\n\n<p>One method is the containment of construction dust by making high protective <a href=\"https:\/\/dustcontroldpcc.delhi.gov.in\/Upload\/GuidelinesPDF\/43\/FilePDF_43_359416.pdf\">barriers<\/a>, like those used at government construction sites, mandatory for all construction and demolition sites, says Shashwat Shukla, a research analyst who has worked at the UN Sustainable Development Solutions Network. Road dust can be reduced in low-income neighbourhoods by paving roads, so that walking commuters like Kumari face lower exposure, he added. According to a 2026 <a href=\"https:\/\/caqm.nic.in\/WriteReadData\/LINKS\/AQI%20Report%20V5%20Final637d7a8a-8dad-44fb-9c8c-8be0dfe42839.pdf\">report<\/a> from India\u2019s Commission for Air Quality Management, these two sources of dust make up 15% of Delhi\u2019s winter air pollution.<\/p>\n\n\n\n<p>Gowande says that in low-income, high-density settlements, the lack of green buffers has led to pollutants lingering. Beig, Shukla and Gowande all note that green cover, such as trees and bushes, should be introduced along roads and medians where possible. In neighbourhoods where space is limited, planting trees on either sides of narrow streets make for good green buffers, Gowande says. Another idea, he proposes, is making some of them pedestrian-only.<\/p>\n\n\n\n<p>None of this, Beig cautions, can be done without planning and forethought. He points to Safar\u2019s air monitoring stations showing that even in the summer, ozone levels were high in some wealthy residential areas because trees that emit volatile organic compounds (VOCs) were planted there. Such VOCs can <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0048969725023551\">interact<\/a> with gases emitted by vehicular exhaust to create ozone and fine particulate matter. \u201cTraditional trees [such as neem, peepal, banyan] that people historically valued and protected tend to be better in this regard,\u201d he says.<\/p>\n\n\n\n<p>Back in Okhla on that December morning, Kumari was dismissive about the chances of change. For her, pollution has become a permanent fixture, her response almost fatalistic about the sun that refuses to rise, or the cough that refuses to go away. \u201cCan\u2019t outrun one\u2019s fate,\u201d she said. For Delhi, the challenge is not just to clear the air, but to make change begin where it is least expected.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Beyond costly air purifiers lies a city trapped by air pollution, with dense neighbourhoods and traditional gender roles exacerbating health impacts for the lower income<\/p>\n","protected":false},"author":50000908,"featured_media":60118106,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[760],"tags":[14274,20000253,551],"hashtags":[],"country":[20000111],"class_list":["post-60118094","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-pollution","tag-air-pollution","tag-gender","tag-health","country-india"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v26.0 (Yoast SEO v26.0) -
