What is hay fever and how does one contact this disease Hay fever or allergic rhinitis is a common illness affecting the nose, ears, and eyes. Often caused by pollens falling from trees, grass and weeds, the resultant effect is sore, itchy eyes, and stuffy, running noses. There is however another type of hay fever which is perennial in nature. This illness occurs round the year and is caused by dust, mite, mold spores, and animal dander.
So how do these foreign agents (allergens) activate such imbalance on the human metabolism Chemical substances, such as histamine, stored in mast cells in tissues of the body, such as the nose and eyes, form antibodies against pollens and other allergens. These antibodies attach to the mast cells, and when combined with the allergen, histamine and other chemical substances from the mast cells are released. These chemical substances cause the allergic responses of itching, sneezing, congestion, and running nose (University of Oregon, Health Center, Allergy Clinic, Allergic Rhinitis, Hay Fever, www.uoregon.edu).
Almost all pollens that are allergens are anemophilous (pollination caused by wind). Ragweed, the bane of hay fever sufferers, is anemophilous. Its pollen has been found at sea hundreds of miles from its source. Spring hay fever often traces to pollens from birches. Other common anemophilous plants are most grass species, conifers, sweet chestnuts, and members of the hickory family (Anemophily, en.wikipedia.org).
Hay fever is not really an illness in medical terminology. This phenomenon is but an extension of normal human events. The cells involved produce up to a pint of fluid a day, even in normal people, but those who are...

...the condition. The most common form of eczema, atopic eczema is a genetic predisposition to become highly sensitized in response to allergens that are common in the environment.
