Ragweed Season Alert!
We are in the ragweed season now; At this time, ragweed pollen is the predominant allergen in the air; it a bad news for people with ragweed allergy. Ragweeds are very prevalent in USA, but the allergy symptoms occur only in the seasons at which the pollen are distributed in the air. There are different types of ragweeds: giant ragweed, short ragweed, perennial ragweed, southern ragweed, and canyon ragweed. Ragweeds are mostly distributed on pastures, open fields, and waste places. The pollen gets airborne and reaches areas near the fields in high concentration. Ragweed pollen entering the nose, most of them, are held back in the nose by filtering mechanisms of the nasal passage, If you are allergic to ragweed pollen, antibodies present in the cells of the nose put up a fight,resulting in release of a chemical called histamine in the nose. Histamine increases the blood flow to the area of contact. The glands of the nasal passage release mucus to digest the proteins of the pollen. This results in a watery discharge from the nose (runny nose). Histamine induces sneezing, which helps to expel the allergenic pollen in the sinuses. Thus, sneezing, runny-nose becomes common problems for thosewith ragweed allergy.
