Hyderabad Air Quality Fuels Respiratory Crisis
21 Jan
Summary
- Particulate matter (PM2.5) is driving respiratory illnesses and allergies.
- Winter pollution in Hyderabad equals passive smoking of 5-6 cigarettes daily.
- Smog hinders vitamin D production, weakening immunity and increasing infection risk.
Hyderabad is experiencing a severe surge in respiratory illnesses, allergies, and immune-related disorders directly linked to worsening air quality. Doctors highlight particulate matter (PM2.5), a byproduct of vehicle exhaust and industrial activity, as a primary culprit. These fine particles accumulate during winter due to reduced wind, leading to prolonged exposure and a period described as the "peak allergy season" from Diwali to Sankranti.
The impact of PM2.5 extends beyond simple breathing difficulties, as these particles can enter the bloodstream, affecting immunity and increasing susceptibility to infections. Doctors have noted a sharp rise in cases of sinusitis, allergic rhinitis, and bronchitis, particularly during November, December, and January. Air pollution acts as a catalyst, worsening pre-existing conditions.
Comparatively, Hyderabad's air quality, often near an AQI of 200, is likened to passive smoking of five to six cigarettes daily, even more so in high-traffic areas. Beyond respiratory issues, the city's smoggy skies are interfering with the body's ability to produce essential vitamin D, further compromising immunity, bone health, and increasing infection risks. Medical advice includes limiting outdoor exposure during peak pollution, wearing masks, and maintaining indoor air quality.
