Pollen and skin allergies on aging people

Allergens hit their body "target organs" in different ways. Airborne or inhalational allergens strike the nose ,IIH.1 bronchi and lungs; food allergens M" absorbed through the intestine and distributed to various parts of the body, frequently showing their effects of the skin; contact allergens affect ski 11, lips, eyes; allergenic medicines also may affect the skin. 

Some persons have physical allergies, developing typical allergic responses to sun lights, heat, cold, or humidity. The symptoms ofallergy depend upon the target or shock organ affected. If it is the nose, there may be congestion, watery discharge, and sneezing, as in hay fever; if the skin is I he target, there may be rash, hives, or eczema; if the bronchial tubes are the target, there is the wheezing of bronchial asthma.  

 Allergies affect both sexes and may appear at any age. There is a strong hereditary factor. One patient with severe hay fever has a son of 21 who had asthma from age 6 to 14 and has had almost no attacks since, as the result of avoiding cats; and a daughter who had hay fever for several years as a child and then "outgrew" it; the remaining child has not been allergic. It is important for any person with allergy, or with even a family history of allergy, to mention the fact to any doctor or nurse who is treating him. 

An allergic or potentially allergic per- son usually will not be given penicillin or certain other medicines known to commonly produce allergic reactions unless the medication is absolutely necessary.

Hay Fever Chief among airborne allergic diseases is hay fever. Curiously, it has nothing to do with hay but is caused by pollens of trees, plants, and weeds. The typical case is seasonal except in a few parts of the South where there may be pollen in the air all year. In the northern United States there is spring hay fever caused by pollens of trees and grasses, and the summer- autumn variety caused usually by ragweed pollen.


The symptoms, which develop, when pollen contacts nose and eyes, include congestion of the nose, watery discharge, tickling and irritation, and sneezing
