In fact, pollen are scattered all year long
Spring may have the image of a pollen season, but this is influenced by the fact that cedar pollen, which has the highest number of people with symptoms, begins to fly in early spring. However, in reality, a variety of plants scatter pollen throughout the year. So it is important to provide care throughout the year. Depending on the weather and area, the pollens get scattered from the grasses e.g. orchard grass, timothy grass (all across Europe), birch (Arctic, central Europe), mugwort, ragweed (Central Europe) and cypress (Mediterrranean). These pollens are reported to cause Pollinosis (respiratory tract allergy problem) majorly in Europe.
