Seasonal allergies are particularly severe in 2025 due to climate change, with cities like Wichita, New Orleans, and Oklahoma City topping the list of allergy misery. Warmer temperatures and increased CO₂ lead to longer pollen seasons and stronger reactions. Individuals can combat allergies by starting medication early, keeping windows shut, showering after being outside, and consulting an allergist.
