  Pollen is the male fertilizing agent for flowering plants, trees, grasses, and weeds. It is also recognized as a significant allergen contributing to seasonal allergic rhinitis symptoms, commonly known as hay fever. This allergenic property of pollen poses a substantial public health concern due to its impact on morbidity and the consequent degradation of patients' quality of life. While pollen particles are generally too large to penetrate the thoracic regions of the respiratory tract, they can affect the nasopharyngeal mucous membrane. Conversely, submicronic pollen fragments can behave as respirable particles, infiltrating deeper into the upper airways. This penetration can exacerbate conditions such as asthma and chronic obstructive pulmonary disease (COPD) and trigger other allergic responses. Weather conditions heavily influence pollen dispersion and its resultant allergic symptoms. Pollen movement is reduced during rainy, cloudy, or windless days, typ...
