Climate change is worsening pollen allergies, leading to longer seasons and increased severity. This impacts public health, healthcare costs, and the prevalence of allergic diseases like hay fever and pollen asthma.
Area of Science:
- Environmental Science
- Allergology
- Public Health
Context:
- Pollen allergy impacts 20% of the population.
- Warmer climates extend pollen seasons and increase pollen counts.
- New allergenic plants may emerge in regions like Denmark.
Purpose:
- To analyze the impact of climate change on pollen allergy prevalence and severity.
- To project the future burden of allergic respiratory diseases.
Summary:
- Climate change intensifies pollen allergy seasons and allergen exposure.
- Increased risk of new plant allergens (ragweed, plane tree, wall pellitory) affecting naive populations.
- Projected rise in hay fever, pollen asthma, and complex allergy cases.
Impact:
- Greater public health challenges due to increased allergy prevalence.
- Escalating healthcare costs for diagnosis and treatment of allergic conditions.
- Extended allergy seasons demanding more resources for patient care.

Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
