As the city grapples with yet another year of worsening air quality, doctors are raising alarm over the compounded impact of scorching heat and dust-laden air on public health. With Delhi consistently ranking among the most polluted cities in the world, the situation has become increasingly hazardous. During the peak smog season last year, the capital’s Air Quality Index (AQI) soared to an alarming 494 on November 18—one of the highest readings recorded since 2015. This year, heat waves are adding another layer of concern.

Medical experts from Paras Health warn that the toxic mix of high temperatures and airborne particulate matter (PM2.5 and PM10) is triggering a sharp rise in respiratory issues across the region. People with chronic lung conditions such as asthma and COPD are at particular risk, but even healthy individuals are experiencing symptoms like dry cough, throat irritation, fatigue, and disturbed sleep.

Dr. Arunesh Kumar, Senior Consultant, Respiratory Medicine, Paras Health, Gurugram, noted, “The combination of extreme heat and air pollution is putting a massive strain on respiratory health in Delhi-NCR. High temperatures increase airway inflammation, while fine dust particles penetrate deep into the lungs. We are seeing a surge in patients complaining of breathlessness, wheezing, and increased dependency on inhalers—even among those with previously stable conditions.”

Doctors explain that early signs of respiratory distress include chest tightness, shortness of breath, excessive mucus, or increased usage of rescue medication in asthma patients. Non-asthmatic individuals may also experience throat dryness, headaches, skin irritation, and general fatigue due to poor air quality. If anyone experiences confusion, dizziness, or bluish lips and fingertips, it may signal dangerously low oxygen levels requiring urgent care.

To stay safe during this high-risk period, experts advise the public to avoid stepping outdoors during peak heat and pollution hours, particularly between 12 pm and 4 pm. When going outside is unavoidable, wearing N95 or equivalent masks can help reduce inhalation of harmful dust particles. At home, using air purifiers, especially in sleeping areas, can significantly improve indoor air quality. Staying well-hydrated is also essential, as it helps keep the respiratory tract moist and facilitates easier breathing. People are further encouraged to shower and change clothes after being outdoors to eliminate pollutants that settle on the skin and fabric.

Avoiding common indoor irritants such as incense, cigarette smoke, and dust accumulation is also crucial, as these can compound respiratory issues. Monitoring the Air Quality Index (AQI) daily can help individuals plan activities and limit exposure on especially poor air quality days. For those with pre-existing respiratory conditions, doctors stress the importance of adhering strictly to prescribed treatment regimens, keeping rescue inhalers close at hand, and seeking timely medical intervention if symptoms escalate.

Delhi’s battle with air pollution is not seasonal anymore—it is a persistent public health emergency. As the region continues to endure the twin threats of rising temperatures and toxic air, timely awareness and protective measures are essential to prevent severe respiratory complications and safeguard community well-being.
