While most of Delhi’s residents are preoccupied with smog-filled skies and rising AQI levels outdoors, a more insidious threat is brewing inside their homes, indoor air pollution. It’s the hidden hazard no one’s really talking about, and according to experts, it can sometimes be even worse than the air outside. Delhi’s indoor spaces are a breeding ground for invisible irritants like dust mites, mold spores, and pet dander, all of which thrive in closed, humid environments. These microscopic culprits can trigger a range of respiratory issues including asthma, bronchitis, wheezing, persistent coughs, and sore throats. “Many of my patients assume that staying indoors protects them from pollution, but that’s often not true,” says Dr. Shahid Patel, Consultant Pulmonologist, Medicover Hospitals, Kharghar, Navi Mumbai. “Indoor air can contain a higher concentration of allergens and particulate matter than outdoor air, especially in cities like Delhi.” The root of the problem lies in poor ventilation, lack of sunlight, and accumulated dust in soft furnishings, carpets, and curtains. Even everyday household activities — cooking, burning incense, or using chemical-based cleaners — can worsen indoor air quality. Over time, these pollutants affect not just the lungs but also sleep quality, immunity, and overall well-being. To counter this silent threat, Dr. Patel recommends a few essential steps: Regular vacuuming and dusting using HEPA filters to trap fine particles.Using allergen-proof bedding and washing linens frequently in hot water.Maintaining optimal humidity levels (between 30–50%) to prevent mold growth.Ensuring cross-ventilation to let in fresh air during low pollution hours.Removing shoes before entering the home to limit dust and chemical residues.Investing in good air purifiers, especially for bedrooms and living spaces.“It’s important to keep the house clean, dust-free, and mold-free,” Dr. Patel adds. “Small changes in daily habits can have a big impact on respiratory health.” In a city battling outdoor pollution, it’s easy to overlook what’s happening behind closed doors. But as Delhi’s residents retreat indoors for safety, the real fight for clean air may very well begin at home. Breathe easy, take control of your indoor air quality, and protect your health from the inside out.
