As the familiar grey haze settles once again over Delhi-NCR, doctors are sounding the alarm on a growing health emergency. The capital’s toxic winter air has pushed hospitals to the brink, with a surge in patients complaining of throat irritation, persistent cough, wheezing, chest tightness, and breathing difficulties.  

A recent survey by citizen platform LocalCircles paints a grim picture — three out of four households in Delhi-NCR have at least one person suffering from flu- or viral-like symptoms. 

Over 15,000 residents from Delhi, Gurugram, Noida, Faridabad, and Ghaziabad took part in the survey, confirming what’s already visible across the city — people are struggling to breathe.  

Adding to the concern, the State of Global Air 2025 report reveals that India recorded more than two million deaths in 2023 due to toxic air. With South Asia’s PM2.5 levels among the world’s highest, experts are calling this not just an environmental issue but a full-blown public health crisis.  

Dr. Rakesh K. Chawla, Head of Respiratory Medicine at Jaipur Golden Hospital, says Delhi stands at the sharp edge of India’s air-pollution emergency. “Every winter, the city’s pollution levels shoot up to nearly ten times higher than the WHO safe limit,” he said.

 “After Diwali and crop burning, a thick layer of cold air traps pollutants, turning Delhi into a gas chamber. This isn’t a temporary inconvenience — it’s a direct attack on our lungs that lowers immunity, worsens asthma, and fuels chronic respiratory diseases. Clean air should be a fundamental right, not a privilege granted by the weather.”  

He emphasized that quick fixes like the odd-even car rule or cloud seeding won’t solve the problem.

 “We need real, long-term solutions — stricter enforcement of emission laws, cleaner public transport, and a ban on open waste and construction dust,” he said. “Unless we change the system, Delhi will continue to relive this health disaster every winter.”  

The financial toll is equally staggering. Experts estimate that air pollution costs India nearly 9.5 percent of its GDP every year through lost productivity and healthcare expenses. One of the biggest health casualties of this pollution is Chronic Obstructive Pulmonary Disease (COPD) — a progressive and incurable lung condition.  “COPD cases have doubled in India, rising from 28 million in 1990 to nearly 55 million by 2016,” said Dr. Aditya K. Chawla, Consultant at Jaipur Golden Hospital and Saroj Hospital.

 “For people living in already polluted cities like Delhi, smoking makes things far worse. Once lung function is lost, no medicine can bring it back. The best treatment is prevention — stop smoking, stay indoors when pollution levels spike, and use clean fuels at home. Awareness, early screening, and strict policies are our only real defence.”  

As Delhi’s air quality once again dips into the “severe” category, doctors warn that without strong action from both citizens and the government, the annual smog season will keep crippling health and productivity. 

The right to breathe clean air, they say, is fast becoming one of Delhi’s most urgent but unfulfilled promises.
