Air Pollution & Kids' Immunity: Why Children Fall Sick More Often in High-AQI Exposure

• Children's developing bodies and immature immune systems make them highly vulnerable to air pollution.
• Higher respiratory rates in children lead to increased intake of harmful pollutants compared to adults.
• Pollution damages the protective lining of the nose and lungs, weakening the immune barrier and causing frequent infections.
• Common illnesses take longer to heal, and children may fall sick repeatedly due to impaired immune cell function.
• Children with asthma or allergies are at higher risk, and outdoor activities on high-AQI days increase exposure.

Why It Matters: Air pollution significantly compromises children's developing immunity, leading to more frequent and severe illnesses.
