Belgium’s Pollen Season Begins: What Allergy Sufferers Demand to Know
Belgium’s pollen season is officially underway, starting January 26th, according to the national aero-biological monitoring network AirAllergy of Sciensano. The first pollens detected are from alder and hazel trees, potentially triggering allergic reactions in sensitive individuals.
Early Symptoms and Medical Consultations
The CHU of Namur is already seeing patients presenting with allergy symptoms. Dr. Dominique Butenda, head of the pneumology department, reports patients are experiencing allergic rhinitis symptoms – sneezing, nasal obstruction, and discharge. These symptoms are appearing more frequently, prompting increased consultations.
For those affected, Dr. Butenda recommends practical steps: “Essentially, we recommend good ventilation of rooms, avoiding bringing pollen into the house, and, if symptoms are severe, consulting a general practitioner to discuss treatment options, such as antihistamines or local treatments to control symptoms.”
A Concentrated Pollen Season
This year, the hazel and alder trees are flowering simultaneously. Nicolas Bruffaerts, a scientific collaborator at Sciensano’s Mycology and Aerobiology service, explains: “This synchronization can lead to more intense exposure to pollen from both species.”
Instead of a gradual release over several weeks, a concentrated pollen peak may occur, increasing the risk of significant allergic reactions for sensitive individuals.
Understanding Pollen Counts and Regional Variations
Pollen counts fluctuate daily based on weather conditions. Warmer, drier, and windier days typically result in higher pollen levels. Monitoring pollen forecasts can help individuals prepare and take preventative measures.
While the initial pollen comes from trees, the season will progress to grasses and weeds, extending the allergy season for many.
The Growing Impact of Climate Change on Pollen Seasons
Experts suggest that climate change is influencing pollen seasons, potentially leading to longer durations and higher pollen concentrations. Warmer temperatures can cause plants to release pollen earlier and for extended periods.
Increased CO2 levels can likewise stimulate plant growth, resulting in greater pollen production. These factors contribute to a growing public health concern for allergy sufferers.
Frequently Asked Questions (FAQ)
When does the pollen season in Belgium typically end?
The pollen season extends through the spring and summer, with different plants releasing pollen at different times. Tree pollen is dominant in spring, grass pollen in late spring/early summer, and weed pollen in late summer/fall.
What are the most common allergy symptoms?
Common allergy symptoms include sneezing, runny nose, itchy eyes, nasal congestion, and fatigue.
Are there any over-the-counter remedies for pollen allergies?
Yes, antihistamines, nasal corticosteroids, and eye drops are available over-the-counter to help relieve allergy symptoms.
When should I notice a doctor about my allergies?
If your symptoms are severe, persistent, or interfere with your daily life, it’s best to consult a doctor.
