As the weather warms up, Canadians are experiencing the familiar symptoms of seasonal allergies, including headaches, congestion, itchy eyes, and runny noses. Dr. Moshe Ben-Shoshan from the Montreal Children’s Hospital noted an increase in patients seeking relief from hay fever, asthma, and eczema due to higher pollen levels.
Climate change is exacerbating allergy seasons, with longer and more severe periods of high pollen counts. Dr. Gordon Sussman, a Toronto allergist, highlighted the impact of pollution, carbon dioxide levels, and light pollution on plant growth and extended pollen seasons.
Recent studies indicate a significant rise in pollen levels, attributing it to rising temperatures globally. Vancouver and Victoria are identified as allergy hot spots due to early and intense tree pollen releases. Aerobiology Research Laboratories reported that these cities consistently face challenging allergy environments.
To manage allergies, experts suggest preventive measures like closing windows at night and avoiding outdoor pollen exposure. Over-the-counter antihistamines, nasal sprays, and eye drops can alleviate symptoms, but desensitization treatments offer long-term relief by introducing small allergen doses to the body. New sublingual immunotherapy tablets are a convenient alternative to injections.
For severe cases, targeted biologic drugs can block specific immune responses causing allergies. It is essential for allergy sufferers to undergo testing to identify triggers and rule out other health conditions mimicking allergy symptoms. Managing allergies effectively involves a combination of prevention, traditional medications, and emerging treatments tailored to individual needs.
