These allergies are caused by: pollen, pet dander, dust particles, and mold spores.
Taking into account the airborne allergens listed above, there are two forms of allergic rhinitis: Seasonal Allergic Rhinitis (also called Hay Fever or Pollinosis) and Perennial Allergic Rhinitis.
Seasonal Allergic Rhinitis occurs during specific flowering periods during pollen season when plants are shedding their pollen. In general, trees flower in the spring, grasses in the summer and weeds in the fall.
Pollen forecasts that take into account the weather are important signals - pollen can't travel in the rain. The pollen forecast is a powerful tool for predicting high pollen days.
Perennial Rhinitis, on the other hand, is characterized for its year-round allergy symptoms. Most symptoms are due to pet dander, dust, and mold. The weather forecast will do little to help you prepare for these symptoms.
If you are sensitive to pollen, you will experience an allergic reaction. General allergy symptoms include:
