As the weather warms up, many Canadians are experiencing the familiar symptoms of seasonal allergies, including headaches, congestion, itchy eyes, and runny noses. Climate change is contributing to longer and more severe allergy seasons, with higher pollen counts affecting North America for over a decade. Factors like pollution, carbon dioxide levels, and light pollution are also impacting plant growth and extending pollen seasons.
In cities across the country, pollen levels have been on the rise, exacerbating allergy symptoms for many people. Regions like Vancouver and Victoria are particularly affected by tree pollen allergies due to their warmer climates, leading to early and intense allergy seasons. Data from Aerobiology Research Laboratories shows that these cities consistently rank among the most challenging allergy environments in Canada.
Managing seasonal allergies involves a combination of prevention strategies, traditional medications, and emerging treatments. Avoidance measures such as keeping windows closed, avoiding outdoor drying of clothes, and wearing sunglasses can help reduce exposure to allergens. Over-the-counter antihistamines, nasal sprays, and eye drops are commonly used for mild allergies, but desensitization treatments can provide long-term relief by modifying the body’s immune response to allergens.
New desensitization options like sublingual immunotherapy tablets offer a convenient way to build tolerance to allergens at home. For severe cases, targeted biologic drugs can be prescribed to block specific immune responses causing allergic reactions. It is essential for allergy sufferers to undergo testing by an allergist to identify triggers and rule out other health conditions mimicking allergy symptoms.
