  • What exactly is allergic rhinitis?
    MedlinePlusMay 2026

    Allergic rhinitis, also called hay fever, is an allergy that happens when pollen from trees, weeds, and grasses gets into your nose and throat. Your body reacts to the pollen by causing sneezing, a runny nose, itchy eyes, and other uncomfortable symptoms.

  • Why do I get hay fever symptoms in spring, summer, and fall?
    MedlinePlusMay 2026

    Trees, weeds, and grasses release pollen into the air during spring, summer, and fall. When you breathe in this pollen, it can trigger your allergies and cause hay fever symptoms during those seasons.

  • How does pollen make my nose runny and eyes itchy?
    MedlinePlusMay 2026

    When pollen enters your nose, your immune system treats it like a harmful invader and releases chemicals that cause inflammation. This inflammation makes your nose runny and clogged, and causes your eyes to itch and water.

  • Can things other than pollen trigger my allergies?
    MedlinePlusMay 2026

    Yes, allergic rhinitis can be triggered by things other than pollen, including dust mites, pet dander, mold, and indoor allergens. Some people have year-round allergies instead of just seasonal ones.

  • Are there foods that can worsen my hay fever?
    MedlinePlusMay 2026

    Some foods can worsen hay fever symptoms in people with pollen allergies, especially raw fruits and vegetables that are related to the plants causing your allergies. If you notice certain foods make your symptoms worse, mention it to your doctor.
