Hay fever allergies are common enough. Also known as allergic rhinitis, hay fever is a result of the action of pollens on the immune system of your body. One can suffer from hay fever throughout the year. The primary culprits in this case are the pollens, and these usually belong to wind pollinated plants.
Being an allergic reaction, hay fever causes revolve around allergens entering your body specifically through the process of inhalation, and also through the eye lining. In response to the entry of the allergens in the airway of your body, the immune system produces antibodies in order to destroy them. At times, there is an overreaction by the immune system, which in turn leads to this allergic condition.
The primary proponents of hay fever causes are pollens. Pollens from a range of trees, grasses, and weeds are responsible for hay fever allergies, which include trees like lime, hazel, olive, and birch amongst various others; grasses like timothy, rye grass; weeds like ragweed, nettle, mugwort, etc. Mold spores are also another cause of hay fever. Like pollens even mold spores are floating through the air looking for a hospitable environment that will promote their growth. Your body offers such an environment.
