Sneeze the Day: Your Seasonal Allergy Survival Guide
Winter is coming to a close across Canada, which means melting snow, longer days and the start of spring allergy season for millions of people. As trees, grasses and weeds begin to release pollen, many Canadians will soon be dealing with sneezing, itchy eyes and stuffy noses (Mayo Clinic, 2024).
What Are Seasonal Allergies?
Seasonal allergies, also called hay fever or allergic rhinitis, occur when your immune system overreacts to harmless particles like pollen and mould spores in the air (Mayo Clinic, 2024). Common symptoms include sneezing, a runny or congested nose, itchy or watery eyes, scratchy throat, post nasal drip and fatigue (Mayo Clinic, 2024). These symptoms can interfere with sleep, concentration, work and school, making allergy season more than just a minor inconvenience (ASEBP Wellness, 2024).
Why Spring Allergies Are Getting Worse in Canada
Across Canada, allergy seasons have been starting earlier and lasting longer, in part due to warmer temperatures and changing climate patterns that boost pollen production (CBC News, 2025). Higher carbon dioxide levels and milder winters help plants grow more vigorously and release more pollen, which can intensify symptoms for people with allergies (CBC News, 2025). In some regions, allergy season now stretches from early spring to late fall, leaving fewer symptom free months for patients (Doctors of BC, 2024).
Different parts of the country see different patterns. Tree pollen is a major trigger in the spring, followed by grass pollen in early summer and ragweed in late summer and fall, especially in central Canada (The Weather Network, 2025). Many Canadians describe feeling like they have almost year round allergies as these seasons begin to overlap (CBC News, 2025).
Simple Steps to Prepare Now
The good news is that there are many practical steps you can take before pollen peaks to reduce symptoms. Checking daily pollen forecasts through weather apps or allergy reports can help you plan outdoor activities for lower pollen times, such as after rain or later in the day (ASEBP Wellness, 2024). Keeping windows closed on high pollen days, using air conditioning when possible and showering and changing clothes after being outdoors can all reduce your exposure (Mayo Clinic, 2024).
Saline nasal rinses help flush pollen from your nasal passages and can ease congestion without medication (Mayo Clinic, 2024). For many people, starting a non drowsy antihistamine or intranasal corticosteroid spray one to two weeks before their usual allergy season provides better control than waiting until symptoms are severe (CBC News, 2015; Mayo Clinic, 2024).
When to Talk to a Healthcare Professional
If over the counter medications are not enough, or if allergies are affecting your sleep, work or breathing, it may be time to see a healthcare professional. Allergy testing can help identify your specific triggers and guide a more tailored plan (ASEBP Wellness, 2024). For moderate to severe allergies, immunotherapy such as allergy shots or under the tongue tablets can reduce sensitivity to pollen over time and may decrease the need for other medications (CBC News, 2015).
People with asthma should be especially proactive, as spring allergens can trigger flare ups and increase the risk of emergency visits (CBC News, 2025). Working with your healthcare team on an up to date action plan before buds appear on the trees can help you breathe easier all season long.
