Seasonal Allergies 2.0
Pollen allergies have become more widespread in recent years. Several factors contribute to this trend, but the link between seasonal allergies and climate change is becoming increasingly evident.
If you’ve noticed worsening seasonal allergies over the years or have developed new allergies as an adult after a lifetime of being unaffected, research indicates that climate change may be partially responsible.
Climate Change and Pollen Power
The rising temperatures and increased humidity associated with climate change promote longer growing seasons for the plants and weeds that trigger seasonal allergies. This extended growing period creates a feedback loop; warmer temperatures and higher carbon dioxide levels enable plants to grow larger and produce more pollen than usual.
In addition, rising ocean temperatures have led to more frequent thunderstorms, during which plants release significant amounts of pollen. These thunderstorms are known to exacerbate seasonal allergic rhinitis and asthma episodes. Furthermore, air pollution independently affects allergen sensitivity, varying by location and air quality.
When considered together, these climate change mechanisms are increasing both the volume of pollen in the air and its potential to cause allergies. The World Allergy Organization forecasts that climate change will continue to influence the timing, length, and severity of the pollen season in the coming years.
Planetary Health
The decline in biodiversity may play a significant role in the rising incidence of allergies and inflammatory diseases in developed nations. As habitats alter and wildlife faces threats, the decrease in biodiversity compromises the environment’s microbiome, which in turn affects the human microbiome.
Studies have shown that children living on farms, who are exposed to a more varied microbiome, have a lower incidence of allergic diseases compared to those living in urban environments.
Urban dwellers, with less access to biodiverse surroundings and interactions with trees, plants, and soil, often experience impaired immune tolerance. This immune tolerance is crucial for the immune system, and when it is hindered, it can manifest as seasonal allergies, food allergies, or autoimmune disorders.
Research indicates that access to diverse microbial environments is linked to a lower prevalence of allergies and autoimmune diseases. Embracing the environment, in this case, truly offers a scientifically-supported benefit!
Eco-Friendly Allergy Management
– Grow your own organic fruits and vegetables to truly support local consumption and reduce greenhouse emissions. Engage with the soil to enhance your microbiome.
– Incorporate more plant-based meals into your diet to lower greenhouse gas emissions and conserve natural resources.
– Follow Quebec’s lead by urging your local government to adopt landscaping practices that control the growth of allergenic plants.
– Dry your clothes on an indoor rack instead of outside to limit pollen exposure while also conserving energy.
– Consult a natural health professional for personalized advice on managing seasonal allergies.
