The festive glow of Diwali often fades into a heavy haze, but this year the after-effects of polluted air are particularly concerning for residents of the Delhi‑NCR. According to Dr Arunachalam M, a senior consultant pulmonologist at Yatharth Hospitals in Noida, the toxic mix of smoke, soot and dust is harming not only lungs but eyes too. He warns that what appears to be fog is in fact harmful smog, aggravating respiratory problems, causing eye redness and watering, and triggering acute discomfort especially in children, seniors and asthma patients. 

To counter these risks, the doctor recommends six smart habits: avoid outdoor activity when the Air-Quality Index (AQI) surpasses 150; protect your eyes with goggles or wrap-around glasses when stepping out; keep eyes moist and clean using preservative-free lubricants; maintain indoor air quality by closing windows during heavy smog, using HEPA air purifiers, and adding air-cleansing plants like money plant or areca palm; nourish body and eyes with antioxidant-rich foods such as carrots, spinach, oranges and nuts; and for asthma sufferers, always carry inhalers, avoid smoke exposure and seek medical advice if symptoms worsen.
