Seasonal symptoms are usually caused by airborne pollen and outdoor molds, which are usually highest at night and the early morning hours, including the following:

  • Tree pollen

  • Grass pollen

  • Outdoor mold spores

  • Weed pollen: Flowers do not cause allergic rhinitis because they do not use wind-borne pollination.
