Current Health Topics and Observances

Do thoughts of spring remind you of lazy days and flip-flops or sneezing and tissues? If you picked that latter, you are not alone. As many as 50 million Americans suffer from allergic rhinitis, the most common allergy illness. It goes by many names including hay fever, seasonal allergies and rose fever, but the results are the same. Symptoms include runny nose, itchy eyes and throat, uncontrollable sneezing and sometimes itching of the skin.

Many seasonal "colds" are actually allergic rhinitis, and will not respond to antibiotics. Seasonal allergic rhinitis happens when pollens and/or particles of plant or animal dander, mold spores, etc., come into contact with the lining of the nose, eyes, or throat. The body's immune system recognizes their presence and starts a reaction to prevent their invasion. In most people this is not a problem. However, in some the immune system is overactive and identifies normally harmless particles as dangerous, producing an excessive reaction that actually causes inflammation. This is known as allergy and the substances causing it are allergens. People are allergic to only certain substances, and the reaction does not usually appear until after several exposures to that substance.

What Is The Cause?

Hay fever is caused by pollens, the most significant in the United States is ragweed. It begins pollinating in late August and continues until the first frost.

Early springtime hay fever is most often caused by pollens of trees such as elm, maple, birch, poplar, beech, ash, oak, walnut, sycamore, cypress, hickory, pecan, cottonwood, and alder.

Late springtime pollens come from the grasses, i.e. timothy orchard, red top, sweet vernal; Bermuda, Johnson and some bluegrasses.

Colorful or fragrant flowering plants rarely cause allergy because their pollens are too heavy to be airborne.

Certain allergens are always present. These include house dust, household pet danders, foods, wool, various chemicals used around the house, and more. Symptoms from these are frequently worse in the winter when the house is closed up.

Mold spores cause at least as many allergy problems as pollens. Molds are present all year long and grow outdoors and indoors. Dead leaves and farm areas are common sources for outdoor molds. Indoor plants, old books, bathrooms, and damp areas are common sources of indoor mold growth. Molds are also common in foods, such as cheese and fermented beverages.

Can Allergies Be Serious?

Patients with seasonal allergies show reduced resistance to respiratory infections, and more severe symptoms when infections occur. Allergies such as hay fever are rarely life-threatening, but often cause lost work days, decreased work efficiency, poor school performance, and a negative effect on the enjoyment of life. Considering the millions spent in anti-allergy medications and the cost of lost work time, allergies cannot be considered a minor problem.

What Can You Do To Help Prevent Attacks?

• Wear a pollen mask when mowing grass or house cleaning (most drugstores sell them)
• Change the air filters monthly in heating and air conditioning systems, and/or install an air purifier.
• Keep windows and doors closed during heavy pollination seasons.
• Rid the home of indoor plants and other sources of mildew.
  Don't allow dander producing animals (i.e. cats, dogs, etc.) in the home.
• Change feather pillows, woolen blankets and woolen clothing to cotton or synthetic materials.
• Enclose mattress, box springs and pillows in plastic barrier cloth.
  Use antihistamines and decongestants as necessary and as tolerated.
• Sleep with the head of the bed tilted upwards. A brick or two placed under bedposts at the head of the bed helps relieve nasal congestion.
• Observe general good health practices: exercise daily, stop smoking, avoid other air pollutants, eat a balanced diet and supplement diet with vitamins, especially C.
• Consider a humidifier in the winter as dry, indoor heat aggravates many allergic people, but beware of possible mold growth in the humidifier.
• Discuss hay fever and allergy symptoms with your physician when you experience an allergic reaction.
