What Is Hay Fever And Its Causes

Filed under: Allergy Treatment — admin @ 9:00 pm

  Most likely you or someone you know has allergies. The telltale itchy, puffy, watery eyes and red, stuffy nose signal changes in the seasons in homes and workplaces across the country. What these people suffer from is allergic rhinitis, or hay fever. The medical name for this condition refers to stuffy and itchy nose (rhin), the most common symptom.

Hay fever is an allergic reaction. It is your immune system’s response to foreign material in the air you breathe. Hay fever usually refers to allergies to outdoor, airborne materials such as pollens and molds.

About 15-20% of the population of the United States has some degree of hay fever. It is found equally in both men and women. Usually hay fever is seasonal, but it can last all year long if the allergen stays throughout the year. Spring and fall are the main hay fever seasons.

Hay fever, like all allergic reactions, is caused by allergens, foreign “invaders” that enter your body by inhalation, by swallowing, or through your skin.

In hay fever, the allergens are airborne substances that enter your airways (mouth, nose, throat, and lungs) via your breathing and the linings of your eyes and sometimes ears via direct contact.

Most of the time it is difficult to identify a specific allergen. Once these allergens come in contact with your airway, the white blood cells of your immune system produce antibodies to the offending substance. This overreaction to a harmless substance is often called a hypersensitivity reaction.

The antibody, called immunoglobulin E, or IgE, is stored on special cells called mast cells. When the antibody comes in contact with the corresponding antigen, they promote release of chemicals and hormones called “mediators.” Histamine is an example of a mediator. It is the effects of these mediators on organs and other cells that cause the symptoms of the allergic reaction, in this case hay fever.

The most common allergens in hay fever are pollens. Pollen is small particles released by flowering plants.

It is moved around by wind to other plants of the same species, which it fertilizes so that the plant can bloom again. Pollens from certain types of trees, grasses, and weeds (such as ragweed) are most likely to cause reactions. Pollens from other types of plants are less allergenic. The time of year when a particular species of plant releases pollen, or “pollinates,” depends on the local climate and what it normal for that species.

Some species pollinate in the spring and others in the late summer and early fall. Generally, the farther north a plant is, the later in the season it pollinates. Variations in temperature and rainfall from year to year affect how much pollen is in the air in any given season. The other common allergens in hay fever are molds.

Molds are a type of fungus that has no stems, roots, or leaves. Mold spores float through the air like pollen until they find a hospitable environment to grow. Unlike pollen, however, molds do not have a season. They are present throughout the year in most of the United States.

Molds grow both outdoors and indoors. Outdoors, they thrive in soil, vegetation, and rotting wood. Indoors, molds (usually called mildew) live in places where air does not circulate freely, such as attics and basements, moist places such as bathrooms, and places where foods are stored, prepared, or discarded.

The amounts of pollen and molds in the air are measured daily in many areas around the United States and reported by the National Allergy Bureau. The pollen and mold counts at which people develop allergic symptoms vary quite a lot by individual. Pollen and mold counts are not very helpful in predicting how a specific person will react.

Risk factors for hay fever include: Family members with hay fever. Repeated exposure to the allergen. Other allergic conditions such as eczema or asthma

Nasal polyps, small noncancerous growths in the lining of the nose.The allergens that cause symptoms in an individual as he or she ages. Symptoms decrease in some allergy sufferers, but not all, as they grow older. Bodily changes of pregnancy may make hay fever worse.
