As winter winds down, many are already bracing for the onset of allergy season. While often associated with spring, allergies can commence much earlier, triggered by pollen from species like cypress trees. Symptoms can easily be mistaken for a common cold, making early diagnosis challenging. Experts are now looking at weather patterns, particularly rainfall in March, to predict the severity of the upcoming grass pollen season.
The overlap between allergy symptoms and those of a common cold can be confusing for sufferers. “The symptoms of allergies and common colds are the same, regardless of the time of year,” explains Juan Fraj Lázaro, head of the Allergology department at the Clínica Universitaria Lozano Blesa in Zaragoza. “Currently, in winter, the predominant type of pollination comes from the Cupressaceae family, including both common cypress and Arizona cypress. Other pollens will follow as the season progresses.”
Looking ahead to spring, a key factor in determining pollen levels will be rainfall. According to Fraj Lázaro, if March brings continued rain, the ground will retain moisture, promoting lush growth of grasses and leading to a high degree of grass pollen. Conversely, a dry March and April could result in lower pollen counts. This potential impact of weather on pollen levels highlights the importance of monitoring forecasts for allergy sufferers.
Beyond traditional medications, immunotherapy – often referred to as allergy shots – remains a viable option for those whose symptoms are not adequately controlled. “When a patient decides to undergo immunotherapy, because conventional treatment has been insufficient, improvement is often seen within the first year,” Fraj Lázaro stated. “It induces a state of intolerance to the allergen in question, in this case pollen, and the treatment should last for a minimum of three years.”
The potential for a significant allergy season underscores the need for proactive management. Understanding the types of pollen prevalent at different times of the year, and monitoring weather patterns, can assist individuals prepare and minimize their exposure. For many, this means starting medications before symptoms even begin, and taking steps to reduce pollen contact, such as keeping windows closed and using air purifiers.
The interplay between climate and allergy seasons is a growing area of research. Changes in temperature and precipitation patterns can influence not only the amount of pollen produced, but also the timing and duration of pollen seasons. This makes accurate forecasting and personalized management strategies increasingly important for public health. The Hospital Clínico Universitario Lozano Blesa, where Dr. Fraj Lázaro practices, is actively involved in research related to allergies and respiratory health, contributing to a better understanding of these complex interactions. The Instituto de Investigación Sanitaria Aragón (IIS Aragón) details ongoing research in this area.
Dr. Fraj Lázaro is also affiliated with the Fundación de la Sociedad Española de Alergología e Inmunología Clínica (SEAIC), as detailed in their 2024 activity report, demonstrating his commitment to advancing the field of allergy treatment and research. He also participates in continuing professional development programs, such as those offered by COMZ, as outlined in their 2025 program.
As we move closer to peak allergy season, staying informed about local pollen counts and weather forecasts will be crucial for managing symptoms. The coming weeks will reveal whether March rainfall will indeed lead to a high pollen load, and individuals should prepare accordingly. Further research into the impact of climate change on pollen seasons will be essential for developing effective long-term strategies to protect public health.
