Yes — absolutely. Children with no known asthma are still biologically vulnerable to AQI 300+ air. PM2.5 causes acute airway irritation, inflammatory response, and measurable lung function reduction even in healthy children. Repeated high-dose exposure during childhood causes permanent deficits in lung function growth. Additionally, AQI 300+ events frequently unmask previously undiagnosed asthma — children who cough repeatedly, wheeze, or become breathless during pollution events may be experiencing their first identifiable asthma episodes. If your child has repeated respiratory symptoms during pollution events, a spirometry and FeNO assessment at Pulmovista Clinics is strongly indicated.
