Why PM2.5 and PM10 Affect Children More than Adults

Children’s Vulnerability to Air Pollution

• Developing Lungs and Immune Systems: Children’s lungs and immune systems are still developing, making them highly susceptible to pollutants.
• Higher Breathing Rates: Children breathe faster and inhale more air per kg of body weight than adults, leading to greater exposure.
• Proximity to Ground Level: Pollutants like PM2.5 and PM10 are concentrated closer to the ground, where children are more exposed.

Health Impacts of PM2.5 and PM10 on Children

Short-term Effects:

• Inflammation and irritation in airways.
• Symptoms: Coughing, wheezing, breathlessness, stinging eyes, and chest tightness.
• Increased susceptibility to respiratory infections.

Long-term Effects:

• Reduced lung capacity: Studies indicate a potential 10-15% reduction in lung capacity.
• Development of chronic conditions like asthma and COPD in adulthood.
• Altered immune responses and structural changes in airways.
• Risk of smaller lung development for children exposed to high PM2.5 levels during growth stages.

• Impact on Pregnant Women and Foetuses

  • Prenatal exposure to air pollution may lead to:
    • Low birth weight.
    • Premature births.
    • Developmental complications.

  Recommendations for Pregnant Women:

  • Minimize outdoor exposure during high pollution periods.
  • Use N95 masks and air purifiers indoors.
  • Maintain a diet rich in antioxidants to combat oxidative stress.

  • Preventive Measures for Children

    Limiting Outdoor Exposure:

    • Restrict outdoor activities during peak pollution hours (early mornings and evenings).
    • Use air quality apps to monitor AQI and plan activities.
    • Opt for indoor play areas with air purifiers.

    Using Air Purifiers:

    • Equip homes with HEPA filter air purifiers to reduce indoor pollution.
    • Regularly clean air conditioning systems and change filters monthly.

    Dietary Interventions:

    • Include antioxidant-rich foods: Spinach, carrots, citrus fruits, and Omega-3 fatty acids.
    • Ensure children drink 1-1.5 liters of water daily to stay hydrated.

    Post-Outdoor Hygiene:

    • Wash hands and face, change clothes, and perform nasal irrigation after outdoor activities.

    Promoting Green Spaces:

    • Develop green balconies or garden areas, as plants like spider plants and snake plants act as natural air filters.

    • Additional Precautions for Children with Pre-existing Conditions

      • Establish a healthcare plan with a pediatrician.
      • Regular monitoring of lung function through spirometry.
      • Maintain detailed records of symptoms and responses to treatment.
      • Opt for telemedicine consultations during severe pollution days.
