Asthma in Early Learning: How to Reduce Triggers and Protect Young Lungs

Asthma is one of the most common chronic conditions in children—and a leading cause of missed school days. In early learning environments, even small steps can make a big difference in helping young children breathe easier and thrive.

Why Asthma Prevention Starts With You

Asthma affects nearly 1 in 12 children in the U.S. and is a leading cause of school absences. Young children spend much of their day indoors, and their lungs are still developing—making early learning centers a critical place to reduce triggers and promote health.

10 Simple Ways to Reduce Asthma Triggers

Clean Air & Surfaces

1. Use fragrance-free, certified cleaning products. Harsh chemicals and scents can irritate young lungs.

2. Vacuum with a HEPA filter and dust weekly. This helps reduce dust mites and allergens.

3. Fix leaks and dry spills immediately. Mold can grow in as little as 24 hours.

4. Improve ventilation with fresh air or air purifiers. Good airflow helps clear out irritants.

Avoid Triggers & Allergens

5. Avoid air fresheners and sprays. Choose natural options like baking soda or open windows.

6. Seal cracks and store food properly. This helps keep pests like mice and cockroaches out.

7. Minimize soft toys and rugs. Use washable items and clean them regularly.

Family Communication & Safety

8. Partner with parents. Request an Asthma Action Plan and have quick-relief medications on hand.

9. Post no-smoking and anti-idling signs. Car exhaust and smoke are common asthma triggers.

10. Support safe play and physical activity. Ensure access to inhalers and monitor for symptoms.

New Research: Cleaner Air, Healthier Kids

A recent WHE pilot study in Philadelphia childcare centers found that using portable air purifiers significantly improved indoor air quality—by 83.2%.

When Medifyair filters were installed, PM2.5 levels dropped from 6.04 µg/m³ to just 1.02 µg/m³, far below EPA health-based benchmarks.

Cleaner air means fewer asthma triggers, better attendance, and healthier classrooms—especially in communities facing environmental injustices.
