Mastering Asthma Peak Week: Essential Tips to Stay Symptom-Free This September
Discover why Asthma Peak Week in September poses challenges across the US and learn proven strategies to protect yourself and your loved ones.
Each year, the third week of September marks Asthma Peak Week in the United States, a period when asthma symptoms and attacks tend to surge. Beyond simply avoiding known triggers, there are practical steps you can take to minimize your risk and maintain better control over your asthma during this critical time.

Asthma symptoms often fluctuate with seasonal changes and environmental factors. If you or your family members notice worsening symptoms in the fall, you’re not alone. Health experts widely recognize this period as a peak for asthma exacerbations.
Keep reading for comprehensive guidance on preparing for Asthma Peak Week and reducing the likelihood of severe asthma episodes.
Understanding Asthma Peak Week
Medical professionals and health organizations across the northern hemisphere identify the third week of September—sometimes pinpointed as the 38th week of the year—as Asthma Peak Week. This timeframe sees a notable rise in asthma attacks and hospital admissions, according to groups like the American Lung Association.
Key factors contributing to this September spike include:
- Peak ragweed pollen season, a leading fall allergen.
- The onset of flu season.
- Children returning to school, increasing exposure to respiratory viruses such as colds and influenza, which can spread to family members.
- Older school buildings with potential mold, poor ventilation, and other asthma triggers.
- Increased air pollution from school buses.
- Exposure to smoking and vaping on school grounds.
- Heightened stress and anxiety linked to the start of a new school year, which can worsen asthma symptoms.
Asthma Peak Week: Key Statistics
- Approximately 25% of all pediatric asthma-related hospital visits occur in September.
- Hospitalizations peak roughly 18 days post-Labor Day for school-aged children and about 20 days after for preschoolers.
- Since 2005, hospitalizations during Peak Week have dropped by over 50%, likely due to improved awareness and preventive measures.
Creating an Asthma-Friendly Home Environment
Indoor allergens such as dust, mold, and pollen can accumulate and trigger asthma symptoms. The Asthma and Allergy Foundation of America (AAFA) and the Centers for Disease Control and Prevention (CDC) recommend several strategies to reduce these risks.
Here are practical steps to minimize indoor triggers, especially when pollen counts are high during September:
Simple Daily Habits
- Keep windows and doors closed during peak pollen periods.
- Implement a no-shoes policy inside the home.
- Cover your hair outdoors to limit pollen exposure.
- Shower and wash hair before bedtime to remove allergens.
- Use HEPA filters in heating and cooling systems.
- Monitor local air quality reports and avoid outdoor activities when pollution or smoke levels are high.
- Avoid exposure to known asthma triggers.
Targeted Trigger Reduction
- Tobacco Smoke: Maintain a smoke- and vape-free home environment. Seek support to quit smoking if needed and encourage loved ones to do the same.
- Dust Mites: Control indoor humidity between 30–50%, vacuum regularly with HEPA-filter vacuums, and wash bedding in hot water.
- Pests: Store food securely, clean up spills promptly, and use pesticides cautiously—avoiding foggers that can provoke asthma.
- Mold: Address leaks, dry damp areas quickly, use dehumidifiers, and avoid harsh cleaning chemicals.
Additional Strategies for Asthma Peak Week
Beyond home adjustments, consider these important measures to safeguard your respiratory health during Asthma Peak Week:
- Follow your asthma action plan consistently and take medications as prescribed.
- Get your annual flu vaccine at least two weeks before flu season starts—September is ideal.
- Practice frequent handwashing.
- Limit close contact with individuals who are ill.
- Wear masks in crowded or high-risk environments.
- Use nasal saline rinses to clear allergens.
- Consult an allergist to optimize asthma management.
- Manage stress effectively.
- Ensure adequate sleep, balanced nutrition, and hydration.
- Consider pneumococcal vaccination, especially for young children, seniors, and those on long-term corticosteroids.
Regular check-ups with healthcare providers are essential for personalized asthma care and trigger management.
