Rising Allergies Linked to Climate Change, WNC Doctor Warns

Rising Allergies Linked to Climate Change, WNC Doctor Warns | Healthcare 360 Magazine


Allergy season has arrived earlier and with greater intensity in Western North Carolina (WNC), according to Dr. Elise Coulson, an allergist at Allergy Partners in Asheville. Patients are experiencing more severe symptoms compared to previous years, largely due to heightened levels of allergens like pollen in the air. Coulson attributes this trend to climate change and shifts in vegetation patterns in the region.

Early Onset of Allergy Season

Dr. Coulson notes a significant uptick in allergy patients seeking treatment as early as March, a period typically outside the peak allergy season. This early onset indicates a shift in allergy patterns, with patients experiencing symptoms sooner than in previous years.

Not only are allergies hitting earlier, but patients are also reporting more severe symptoms. Coulson attributes this escalation to higher concentrations of allergens, such as pollen, circulating in the air. These elevated allergen levels exacerbate allergic reactions and contribute to heightened discomfort among patients.

Factors Contributing to Allergen Proliferation

Coulson identifies three key factors driving the proliferation of allergens in Western North Carolina. Firstly, updates to the USDA’s plant hardiness zoning map have facilitated the survival and proliferation of plants that previously struggled in colder climates. Additionally, the region’s higher altitudes further enhance the flourishing of allergenic vegetation, extending the allergy season across varying elevations. Lastly, warmer weather conditions, attributed to climate change, have created a more favorable environment for allergen-producing plants to thrive beyond traditional winter months.

Impact of Climate Change on Vegetation

To elucidate the effects of climate change on vegetation patterns, WLOS Chief Meteorologist Jason Boyer collaborated with Climate Central to analyze temperature data. The findings reveal a significant increase in average winter temperatures since 1970, resulting in diminished cold snaps and milder winters. Consequently, this prolonged warmth enables allergenic plants to survive and propagate year-round, intensifying allergy symptoms for affected individuals.

Despite the challenges posed by climate-induced allergies, Dr. Coulson emphasizes proactive measures to alleviate symptoms. Patients are advised to utilize nasal sprays and eye drops to manage discomfort effectively. Additionally, allergy shots offer a long-term solution by desensitizing the body to allergens. Implementing strategies to minimize allergen exposure indoors, such as regularly changing HVAC filters and keeping windows closed, can also mitigate allergy symptoms.

The escalating prevalence and severity of allergies in Western North Carolina underscore the profound impact of climate change on environmental dynamics. As allergens proliferate and allergy seasons lengthen, healthcare providers urge individuals to prioritize symptom management and adopt preventive measures to safeguard their health. By raising awareness and implementing proactive strategies, communities can mitigate the adverse effects of climate-induced allergies and enhance overall well-being.
