Delhi's Silent Epidemic: Pollution's Deadly Toll
6 Nov
Summary
- Pollution causes lung mutations, increasing cancer risk in non-smokers.
- Severe air quality triggers health emergencies, worsening existing conditions.
- Air pollution poses a heart attack risk comparable to smoking and cholesterol.
Delhi and the National Capital Region are experiencing a severe air quality crisis, with the Air Quality Index (AQI) entering the "severe" category before Diwali. This alarming situation has led to the implementation of Stage-III restrictions across the NCR. Experts describe the current air pollution as a "silent epidemic," noting a 20% increase in patients reporting breathing difficulties and chest tightness.
While individuals with pre-existing asthma and COPD are severely affected, even healthy people are experiencing throat irritation, coughs, and wheezing. Children and the elderly are identified as the highest-risk groups. Recent studies indicate that poor air quality leads to a surge in emergency visits for respiratory issues within days, linked to increased mortality.
Dr. Randeep Guleria highlights that severe pollution can trigger heart attacks by causing inflammation in blood vessels, posing a risk comparable to smoking and high cholesterol. Furthermore, growing evidence suggests prolonged exposure to polluted air elevates the risk of lung cancer, even in non-smokers, with the condition now appearing more frequently in non-smokers than smokers.
Immediate protective measures include monitoring AQI, wearing masks outdoors, and keeping windows closed. Long-term solutions must address emission sources like vehicles and construction, alongside weather-related factors. Authorities are urged to develop sustainable plans to decrease emissions and mitigate the pervasive impact of air pollution on public health.
