As winter smog blankets Delhi NCR, slum dwellers like Besaniya in Chaura Basti face severe health risks from indoor air pollution. With no access to clean cooking fuels, residents rely on firewood for warmth and cooking, trapping toxic smoke in their cramped, poorly ventilated homes. This smoke, laden with fine particulate matter (PM2.5) and harmful gases, is up to 100 times more dangerous than outdoor pollution, causing respiratory issues, low birth weights, and chronic illnesses. Despite government initiatives like the Pradhan Mantri Ujjwala Yojana, high LPG refill costs and lack of documentation force many to continue using firewood. Pregnant women and children are particularly vulnerable, with studies linking indoor pollution to asthma, pneumonia, and stillbirths. Residents, unaware of the long-term health impacts, often attribute their ailments to seasonal changes, highlighting the urgent need for affordable, sustainable solutions to combat indoor air pollution in marginalized communities.
