Autumn allergies: Causes and symptoms of seasonal triggers

While allergies are commonly associated with spring and summer, symptoms such as sneezing, nasal congestion, and itchy eyes can persist or even intensify during September and October.

Key autumn allergens include ragweed, which releases large amounts of pollen that can be transported long distances by air currents. This can trigger allergic rhinitis and conjunctivitis, or exacerbate asthma symptoms like coughing and wheezing. Additionally, autumn conditions—such as fallen leaves, moist soil, and increased rainfall—create ideal environments for mold growth. Mold spores released into the air can further irritate the respiratory tract, particularly after activities like gardening or handling damp vegetation.
