Cultivated oat grass (Avena sativa) is a common cereal crop grown extensively across temperate regions. Besides its agricultural uses, it is a known airborne allergen. During its pollination season, oat grass releases pollen that can become airborne and inhaled, potentially causing allergic reactions in sensitive individuals. Symptoms may include sneezing, nasal congestion, itchy eyes, and respiratory irritation. It is one of many grasses whose pollen can contribute to seasonal allergic rhinitis, also referred to as hay fever.
Yes, many grass pollens share similar proteins, and cross-reactivity is common among species like timothy grass, ryegrass, and cultivated oat grass. This can make it difficult to identify the exact source of symptoms without specific testing.
Oat grass typically pollinates in late spring to early summer, but this can vary depending on the climate and region.
