Spring Allergies Set to Surge: How Weather Patterns are Changing the Game
This spring promises a particularly challenging season for allergy sufferers, according to experts at the Spanish Society of Allergology and Clinical Immunology (SEAIC). Recent weather patterns, specifically increased rainfall and fluctuating temperatures, are creating a perfect storm for both pollen and mold allergies, as well as exacerbating asthma symptoms.
The ‘Washout Effect’ and Delayed Pollen Season
Prolonged rainfall, as experienced in early 2026, isn’t simply delaying allergy season – it’s reshaping it. The “washout effect” describes how heavy rains temporarily remove pollen from the atmosphere. Even as providing temporary relief, this too concentrates pollen levels when the weather stabilizes, potentially leading to a more intense and prolonged allergy season. Dr. Juan José Zapata, president of the SEAIC’s Clinical Aerobiology Committee, explains that this could mean a significantly higher pollen concentration than usual.
Humidity and the Rise of Mold & Asthma Concerns
Beyond pollen, increased humidity is fueling the growth of mold and dust mites – common triggers for asthma. This is particularly concerning as these allergens can affect individuals even in areas where they weren’t previously a significant problem. Dr. Juan Carlos Miralles, president of the SEAIC’s Asthma Committee, highlights that high humidity alters the epithelial barrier in the respiratory system, making it harder to clear mucus and increasing sensitivity to these allergens, potentially leading to more severe asthma attacks.
A Two-Phase Impact: Asthma Now, Pollen Later
The impact of these weather conditions is unfolding in two phases. Currently, the increased humidity is primarily affecting individuals with asthma. However, the real challenge for pollen allergy sufferers will arrive when the rains subside and pollen release accelerates. This creates a complex scenario requiring proactive management strategies.
What Can Allergy and Asthma Sufferers Do?
Experts recommend a multi-pronged approach to mitigate the impact of these changing conditions.
For Pollen Allergy Sufferers:
- Monitor Pollen Levels: Regularly check pollen counts through specialized platforms.
- Consult an Allergist: Discuss potential adjustments to your allergy management plan.
- Environmental Control: Minimize exposure by avoiding heavily gardened areas during peak pollen times, keeping windows closed, and using controlled ventilation.
For Asthma Sufferers:
- Control Indoor Humidity: Utilize dehumidifiers to reduce moisture levels in the home.
- Avoid Damp Spaces: Limit time spent in areas prone to dampness.
- Adhere to Treatment: Strictly follow your preventative treatment plan and always have your rescue inhaler readily available. Seek immediate medical attention for worsening symptoms.
Looking Ahead: Long-Term Trends and Climate Change
These recent weather patterns aren’t isolated incidents. Climate change is expected to exacerbate these trends, leading to more frequent and intense rainfall events, as well as shifts in pollen seasons. This will likely result in longer and more severe allergy seasons, and a broader geographic distribution of allergens.
The SEAIC emphasizes the importance of ongoing research to understand these evolving patterns and develop effective strategies for managing allergic diseases in a changing climate.
FAQ
Q: What is the ‘washout effect’?
A: The ‘washout effect’ refers to how heavy rainfall temporarily removes pollen from the air, delaying but potentially intensifying the pollen season.
Q: How does humidity affect asthma?
A: High humidity can worsen asthma by altering the respiratory system’s barrier, making it harder to clear mucus and increasing sensitivity to mold and dust mites.
Q: When should I see a doctor about my allergies?
A: Consult an allergist if your symptoms are severe, interfere with your daily life, or don’t respond to over-the-counter treatments.
Q: Is climate change making allergies worse?
A: Yes, climate change is expected to exacerbate allergy symptoms through increased rainfall, shifting pollen seasons, and a broader distribution of allergens.
Did you know? The SEAIC is celebrating its 75th anniversary in 2026, marking decades of research and advancements in the field of allergy and immunology.
Pro Tip: Regularly cleaning your home, especially areas prone to moisture, can significantly reduce mold and dust mite allergens.
