The Impact of Climate Change on Allergies: Rising Concerns for Canadians

With each passing year, more Canadians find themselves grappling with allergies, and experts are attributing this increase to the effects of climate change. The rising number of cases involving respiratory distress among children has become a growing concern for parents like Daniela Mora-Fisher and her husband. Their toddler’s breathing troubles have escalated to the point where hospital visits have become a regular occurrence. As the prevalence of allergies continues to rise, it is crucial to understand the link between climate change and allergic reactions and explore potential measures to alleviate symptoms and improve quality of life.

A Complex Nexus: Allergies, Viruses, and Asthma:

Daniela Mora-Fisher, a researcher at a Toronto doctor’s office, suspects that a combination of allergies and viruses may be triggering her toddler’s respiratory distress, possibly leading to asthma. Despite seeking medical attention, the diagnosis remains elusive until the child is old enough to undergo necessary breathing tests. Mora-Fisher and her husband have made significant efforts to minimize potential allergens, even moving to a new residence in an attempt to escape mold and reduce exposure to traffic-related pollutants. However, their experiences highlight the challenges faced by many families in combating allergies exacerbated by climate change.

The Soaring Trend of Allergies:

According to Dr. Susan Waserman, an allergy specialist at McMaster University, the rise in allergies and related conditions, such as eczema, allergic rhinitis, asthma, and food allergies, has been observed over several decades. Climate change, a significant factor influencing this trend, has led to an extended pollen season and an increased release of pollen by plants. Aerobiology, a Canadian company monitoring airborne allergens, confirms a year-over-year rise in pollen concentrations. The correlation between warmer weather resulting from climate change and heightened pollen levels is undeniable.

Early Onset and Environmental Impact:

In recent years, healthcare professionals like Dr. Waserman have noticed a concerning shift in the age at which allergies manifest. Allergic reactions, previously believed to appear around the age of five, are now occurring in younger children. Exposure to allergens and pollutants, combined with a genetic predisposition, primes respiratory tissues and immune systems for the development of allergies and asthma. Furthermore, climate change-induced flooding increases mold growth in homes, leading to additional indoor allergens.

The Role of Fossil Fuel Emissions and Wildfires:

The burning of fossil fuels releases inhalable particles into the air, irritating respiratory systems and potentially triggering allergic responses. Dr. Melissa Lem, President of the Canadian Association of Physicians for the Environment (CAPE), points out that the very factors driving climate change also exacerbate allergies. Furthermore, an increase in wildfires directly linked to climate change worsens air quality, resulting in a surge of respiratory symptoms among individuals.

Addressing the Challenges:

To mitigate the impact of allergies influenced by climate change, proactive measures can be taken at both individual and community levels. Implementing air purifiers at home can help reduce indoor allergens. People exposed to pollen should consider changing clothes and showering after spending time outdoors. Fortunately, advancements in allergy medications, such as desensitizing tablets, offer improved treatment options for allergy sufferers. It is essential for individuals to recognize the significance of allergies on their quality of life and seek appropriate support from healthcare providers.


As climate change continues to shape our environment, the prevalence of allergies among Canadians remains on the rise. The correlation between warmer weather, increased pollen levels, and the exacerbation of allergic symptoms is evident. It is imperative to acknowledge the impact of climate change on allergies and take proactive steps to mitigate its effects. By combining efforts to reduce climate change with immediate measures to manage allergies, individuals can improve their overall well-being and regain control over their lives. Allergy symptoms should never be disregarded, as addressing them can significantly enhance one’s quality of life.
