Spring Allergies Arrive Early and Stronger in 2026: What You Need to Know
Each year, as spring approaches, millions of people look to the sky not just to check for rain, but to anticipate the intensity of their allergy symptoms. 2026 appears to be no exception.
Following months marked by persistent rains and a succession of storms, specialists are warning of a potentially complicated season for those who suffer from pollen allergies.
A Complicated Forecast: Rain, Pollen, and Climate Change
Experts predict a challenging spring for allergy sufferers due to increased vegetation growth fueled by recent heavy rainfall. Marcela Santaolaya Montoya, an allergist, notes that this abundant vegetation will release greater amounts of pollen when it begins to pollinate. The situation is expected to be similar to last year’s already difficult spring season, though the final outcome will depend on spring weather patterns.
Continued rainfall during the spring could help clear the atmosphere and deposit pollen on the ground, partially reducing symptoms. Yet, when sunny weather arrives, pollen levels could surge rapidly.
Beyond an Early Start: Explosive Pollination
It’s not simply an earlier start to the allergy season, but rather a “very explosive” pollination, according to Juan José Zapata, president of the Aerobiology Committee. Species like cypress, common in urban areas, and stinging nettle begin releasing pollen in January, but the recent storms limited effective pollination days. Now, with sunshine, they are pollinating intensely, leading to a rapid increase in pollen concentration and impacting sensitive individuals.
The difference between winter and spring pollens doesn’t lie in the symptoms they cause, but in when each species releases its pollen. In the interior of the Iberian Peninsula, cypress pollen predominates from January, followed by plane trees, grasses, and olive trees, which are responsible for many cases of rhinitis, conjunctivitis, and asthma exacerbations.
Symptoms and Confusion with Common Colds
Distinguishing allergy symptoms from the common cold can be difficult, especially in winter. A common cold typically lasts five to seven days and may include fever, headache, or general malaise, although allergies respond better to antihistamines. However, symptoms can overlap, making diagnosis challenging without specialist evaluation.
Common symptoms include rhinitis and conjunctivitis, as well as asthma attacks, the intensity of which depends on pollen concentration and the patient’s prior condition. Children may experience a more intense immune response than adults. Specialists are also observing a growing trend: the appearance of allergies at advanced ages, even in people who have never had symptoms before.
Managing Allergy Symptoms: Practical Advice
To reduce exposure, experts recommend limiting outdoor activities during the first and last hours of the day, ventilating homes during midday, avoiding hanging laundry outdoors on high-pollen days, and showering upon returning home. Wearing sunglasses and FFP2 masks outdoors can also act as a physical barrier.
Regarding pharmacological treatment, it’s important not to “fall short” with antihistamines and topical corticosteroids, adjusting doses to the intensity of symptoms.
Immunotherapy: A Potential Long-Term Solution
The use of specific immunotherapy – commonly known as a “vaccine” – is growing as a strategy to modify the course of the disease. Approximately half of patients for whom This proves indicated choose this treatment. Some experts attribute a lack of awareness to the limited presence of allergology within the healthcare system.
However, immunotherapy can “perfectly cure” allergies to certain pollens and improve outcomes compared to continued symptomatic medication. The procedure involves administering increasing doses of the allergen until a therapeutic dose is reached, followed by monthly injections for three to five years.
The goal isn’t to stimulate defenses against an infectious agent, as with conventional vaccines, but to induce immunological tolerance. “I make them tolerant, and once they are tolerant, they no longer have symptoms,” explains Zapata. Indicated for those five years and older, immunotherapy is emerging as a key tool in a context where projections point to a sustained increase in allergic diseases.
As spring progresses and pollen levels fluctuate with the weather, more and more patients are considering this option not only to relieve seasonal symptoms but also to try to change their long-term prognosis.
Frequently Asked Questions
- What is immunotherapy? It’s a treatment that gradually exposes you to the allergen to build tolerance and reduce symptoms over time.
- Can allergies develop later in life? Yes, allergies can appear at any age, even in people with no prior history.
- How can I reduce my exposure to pollen? Limit outdoor activities during peak pollen times, ventilate your home strategically, and wear protective gear like sunglasses and masks.
- Is there a difference between allergy symptoms and a cold? Colds often include fever and body aches, while allergies typically cause itchy eyes and a runny nose.
Pro Tip: Start taking allergy medication a few weeks *before* the pollen season begins to maximize its effectiveness.
Did you know? The increasing frequency of storms and changing climate patterns are contributing to more intense and prolonged allergy seasons.
