What Is the “Asthma Peak”?
Every year in late August through September, doctors and hospitals see a surge in asthma attacks, especially among children. This period, often called the “September asthma peak” or “back-to-school asthma surge,” is when asthma-related emergency visits can jump dramatically.
According to research, this spike happens shortly after school starts, with the third week of September often being the peak for ER visits in children with asthma.
Why Does It Happen?
Generally, the back-to-school asthma peak is triggered by several factors working together.
- Cold and Flu Viruses – Kids are suddenly in close contact again, increasing the spread of respiratory infections that can trigger asthma.
- Environmental Allergens – Ragweed pollen and mold spores are often high in late summer and early fall.
- Routine Changes – Summer schedules may have led to missed medications or inconsistent asthma management.
- School Triggers – Dust, cleaning chemicals, and classroom pets can worsen symptoms.
- Weather Changes – Cooler mornings and fluctuating temperatures can irritate airways.
How to Prepare Your Child for the Back-to-School Asthma Season
Schedule a Pre-School Check-Up
- Review your child’s asthma action plan with their healthcare provider.
- Update prescriptions and make sure inhalers aren’t expired.
Share the Asthma Action Plan with the School
- Provide copies to the school nurse, teachers, and coaches.
- Make sure your child has quick access to rescue medication at school.
Focus on Medication Adherence
- Restart controller medications before school begins if they were paused over summer.
- Use reminders to ensure daily doses aren’t missed.
Limit Exposure to Illness
- Teach handwashing and remind kids to avoid sharing drinks or utensils.
- Get your child’s flu shot early in the season.
Identify and Reduce Triggers
- Discuss potential classroom triggers with the teacher.
- Encourage allergy management strategies if needed.
What to Watch For
If symptoms worsen or don’t respond to medication, seek medical attention promptly.
- Increased coughing, especially at night
- Wheezing or chest tightness
- Shortness of breath during normal activities
- More frequent rescue inhaler use
The Bottom Line
The September asthma peak is predictable—but it’s also preventable. With preparation, communication, and consistent asthma management, your child can enjoy a healthier, more active school year.
