New Delhi: Delhi’s worsening air pollution is raising serious concerns about the long-term health of children, whose developing lungs, brains and immune systems make them more vulnerable to toxic pollutants than adults. Health experts warn that repeated exposure to polluted air during childhood can have consequences that may continue well into adulthood.
Children breathe more air relative to their body weight than adults. Their respiratory systems are still developing, and their natural defences against harmful pollutants are not yet fully mature. As a result, exposure to the same level of pollution can have a greater impact on their bodies.
Lung Development at Risk Fine particulate matter, particularly PM2.5, can travel deep into the lungs and trigger inflammation. Prolonged exposure may restrict normal lung growth, reduce lung capacity and increase the risk of asthma, respiratory infections and other chronic breathing problems. Experts caution that damage during crucial growth years could leave some children with reduced respiratory capacity later in life.
Pollution May Also Affect Brain Development The consequences are not limited to respiratory health. Emerging research suggests that long-term exposure to fine particles may affect brain development, attention, memory and learning abilities. Researchers have also examined possible links between childhood exposure and changes in cognitive development. However, the precise impact on an individual child's intelligence or academic performance is not yet conclusively established.
Precautions for Parents During periods of severe pollution, parents should limit children's outdoor activities, particularly strenuous exercise. Keeping windows closed when outdoor air quality is poor, using appropriately sized air purifiers with effective HEPA filters and ensuring children wear properly fitted N95 masks when outdoor exposure is unavoidable can help reduce exposure.
Experts stress that protecting children requires more than temporary restrictions. Sustained action to reduce pollution from vehicles, industries, construction dust and other sources is essential to safeguard the health of future generations.
