What is a common allergen that can trigger allergic rhinitis?

Allergic rhinitis, often referred to as hay fever, is an allergic response that can be triggered by various environmental substances, commonly known as allergens. Pollen is a well-known allergen that peaks during certain seasons, leading to increased symptoms in individuals who are sensitive to it. Trees, grasses, and weeds release pollen into the air, and when inhaled by susceptible individuals, it can cause inflammation in the nasal passages. The immune system reacts by releasing histamines, which results in typical symptoms such as sneezing, runny nose, itchy eyes, and nasal congestion.

While allergens like dust mites, mold spores, and pet dander can also cause allergic rhinitis, pollen is particularly notable for its seasonal impact, affecting many individuals during specific times of the year. Understanding the role of pollen in triggering allergic reactions is crucial for managing and preventing allergic rhinitis effectively. Allergen exposure management often involves avoiding high pollen counts during peak seasons and using appropriate medications as prescribed.
