US · Published Oct 29, 2026
• According to Wisconsin Public Radio, warming temperatures are causing longer and more intense allergy seasons in Wisconsin.

Impact & Risks

The extended allergy seasons in Wisconsin are affecting a growing number of residents, including children and adults who may experience symptoms such as sneezing, congestion, and itchy eyes. Chronic inflammation from allergies can lead to fatigue, irritability, and secondary issues like sinus infections and breathing difficulties, particularly for those with asthma. Children may also face developmental issues if nasal congestion disrupts proper breathing during sleep. The prolonged exposure to allergens could increase healthcare costs and reduce productivity due to allergy-related discomfort.
