Fall in Northern Virginia often brings a rise in allergy and asthma symptoms. Common triggers include ragweed pollen, mold spores, weather changes, and increased indoor exposure.
If you notice congestion, sneezing, itchy eyes, or cough every August through October, seasonal allergies may be the cause.
Common Symptoms
Fall allergies may cause:
- Sneezing
- Runny or stuffy nose
- Itchy nose or throat
- Red, watery, or itchy eyes
- Postnasal drip
- Sinus pressure
- Throat clearing
- Cough
- Fatigue
- Worsening asthma
These symptoms are often mistaken for colds or sinus infections.
Ragweed
Ragweed is a major cause of late-summer and fall allergies. Its pollen travels long distances, so symptoms can occur even without nearby plants.
Sensitive individuals may experience significant nasal and eye symptoms during ragweed season.
Mold Exposure
Outdoor mold spores also increase in the fall, especially around decaying leaves and damp vegetation. Symptoms may worsen during yard work or leaf raking.
Indoor moisture problems can also contribute to mold exposure.
Asthma and Fall Allergies
Yes—fall allergens can worsen asthma by increasing airway inflammation. Symptoms may include:
- Coughing
- Wheezing
- Chest tightness
- Shortness of breath
- Exercise intolerance
- Nighttime symptoms
- Increased need for rescue medication
Worsening asthma should not be considered a normal part of allergy season.
Reducing Exposure
Helpful steps include:
- Keep windows closed during high pollen days
- Use air conditioning when possible
- Shower after outdoor exposure
- Change clothes after being outside
- Avoid placing outdoor clothing on beds
- Wear a mask during yard work or leaf raking
- Control indoor humidity
- Fix water leaks promptly
- Take prescribed medications consistently
When to Consider Allergy Testing
See an allergist if symptoms are persistent, recurrent, severe, or affect sleep, work, school, or daily life.
Testing can identify sensitivities to pollens, molds, dust mites, pets, and other allergens, allowing for a more targeted treatment plan.
If Medications Are Not Enough
Treatment may include avoidance strategies, nasal sprays, antihistamines, asthma medications, and other therapies based on individual needs.
For appropriate patients, allergen immunotherapy (allergy shots) may be recommended. This treatment gradually reduces sensitivity to allergens over time.
When to See an Allergist
Consider evaluation if:
- Symptoms return every fall
- Over-the-counter medications are ineffective
- You have persistent congestion or chronic cough
- Sleep or daily activities are affected
- Asthma worsens during allergy season
- Triggers are unclear
- You want to explore allergy shots
Stay Ahead of Symptoms
You do not need to wait until symptoms become severe. Early evaluation and treatment can help prevent worsening allergies and asthma.
