Every year, as the air quality in Delhi-NCR dips, concerns over its impact on children grow stronger. The toxic smog that blankets the region has long been linked to lung problems, but recent findings show that its effects reach far beyond the respiratory system. Doctors now warn that polluted air can seriously harm children with heart conditions, making them even more vulnerable during high-pollution months.
With pollution levels rising annually, children are increasingly exposed to harmful particles like PM2.5, nitrogen dioxide and ozone. Since their bodies are still developing, these pollutants can put them at risk for complications, especially if they already have heart defects. Many of these children struggle with conditions such as holes in the heart or have undergone surgeries to correct them. Their hearts already work harder than normal, and when the air turns toxic, the added strain becomes difficult for their bodies to handle.
One of the most concerning pollutants is fine particulate matter, or PM2.5. These tiny particles can enter the bloodstream, cause inflammation, thicken the blood and irritate blood vessels, all of which can limit oxygen flow. A pediatric cardiologist explained that while healthy children can adjust to some level of environmental stress, those with heart problems cannot. For them, the constant exposure to polluted air creates long-term stress on the body and gradually worsens their condition.
As the smog continues to worsen each year, it becomes more important than ever to protect children—especially those with fragile hearts—from the dangerous effects of Delhi-NCR’s declining air quality.
