Canadian researchers say seasonal allergies are getting worse in recent years as pollen levels increase across Canada. The experts attribute the change to pollen released by plants during reproduction, noting that more airborne pollen can intensify common allergy symptoms such as runny or stuffy nose, itchy eyes, sneezing, and other hay-fever-like reactions. One report describes pollen as rising over multiple years, suggesting a broader shift rather than a single-season spike. The same account also links heightened pollen exposure to allergic skin reactions, including hives, indicating that the impact extends beyond typical upper-respiratory symptoms. While the reporting focuses on pollen and symptoms, it does not detail individual causes for the increase or quantify how pollen growth varies by region or plant species. Overall, the sources present a consistent message: higher pollen availability contributes to more frequent or severe allergic responses among people who are sensitive to allergens, reflecting concerns that seasonal allergy sufferers may experience stronger symptoms as pollen season intensifies.
