What Causes Seasonal Allergies

Allergies are an inflammation of the mucous membranes that are along the nasal passages. The most common of the seasonal allergies is defined as hay fever and is caused by the many pollens that are carried through the air and that come from grasses, trees, weeds, and even flowers.

The beginning of the allergy season begins with spring when many of the trees and flowers are pollinating. They use cross pollination in order to survive and because of this the pollen becomes airborne. Depending on where you are at will depend on how long the pollen is carried through the air and is in the area.

In some places the pollen is so thick that you are able to see a thick layer that is on top of cars and homes. For people with the more severe type and symptoms of seasonal allergies it can be quite difficult for them and the symptoms are so severe that they have to skip work or school.

Pollen is not the only thing that is carried through the air and is able to cause the allergies and the symptoms associated with it to flare up. Some plants will have spores or mold that will carry it through the air and it will enter into the nose, eyes, and throat of people. When this happens it will trigger the seasonal allergy symptoms. For most people the body will be able to respond to these allergens like it would any other type of infection.

People who’s immune system are vulnerable will not be able to respond to these allergens the way that it should. When the immune system has detected these allergens it will release a range of chemicals like histamine and other things. This will cause inflammation, irritation, and discomfort. This will cause the symptoms to flare up – which can take up to five to ten minutes.
