The Role of Environmental Allergens in Rising Asthma Prevalence in Urban Settings

Abstract

A growing body of evidence points to environmental allergens as central to the climbing asthma rates now reported in nearly every major city. This research aims to map how greater contact with both household and street-level irritants tracks with the expansion of clinical asthma diagnoses. By sifting through existing epidemiological registers, scientific reviews, and original field-collected data, the analysis spots the pollen, dust, and mold strains most often at fault. Crumbling apartment stock, ever-heavier traffic fumes, and parks disappearing under concrete all appear to shove allergen totals upward and push residents’ lungs toward the breaking point. Quick, deliberate steps to lower airborne triggers-in concert with smarter city zoning-may be the clearest path to easing tomorrow’s respiratory burden.
