Environmental Control for Indoor Allergens

House dust contains a variety of allergens such as insect parts, animal dander, and dust mites. Furthermore, mold may also be present in homes. It is important to eliminate as much allergen as possible from the home in order to derive maximum benefit from your treatment.

House Dust Mite is probably the most important allergen in most homes. Controlling house dust mite exposure will decrease symptoms in allergic patients and may decrease the risk of developing dust mite allergy in patients not yet sensitized. Dust mites are tiny microscopic creatures that thrive in warm, moist climates. Upholstery (particularly the bed) is the ideal habitat for dust mites because they need the protection of the padding and a food supply (shed human skin) to survive. They cannot thrive on non-porous surfaces or in cool dry climates.

There are simple things you can do to minimize dust mite exposure:

You should concentrate on the bedroom (particularly the bed) because this is where you spend most of your time. In fact, when you are sleeping, you are breathing with your mouth and nose inches from a whole army of dust mites. The bedroom should be clutter free.

Dusting should be done frequently with a damp cloth.

The humidity in the bedroom should be kept below 50%. In Central Oklahoma this generally requires only air condition, but may require a de-humidifier. Humidifiers encourage dust mite and mold growth and should be avoided.

The mattress, box spring and pillow should be encased in dust mite proof encasements. All items on the bed should be washed in hot water (140 degrees) every one to two weeks. Stuffed animals should be removed from the bed.

Upholstered furniture and wall to wall carpet contain dust mites and should be avoided if possible, but these are not nearly as important as the bed.

Air filters, expensive vacuum cleaners, and duct cleaning help only minimally. When vacuuming, a HEPA filter or double bag should be used to minimize dust mites being stirred up and released into the air.

Cockroaches are now recognized as important indoor allergens. Other insects such as lady bugs, spiders, and crickets have recently been implicated. Keep the home clean and dry and fix any leaks or drips. It may be necessary to have an exterminator treat the home periodically.

Animal dander, generally from cats and dogs (but sometimes from gerbils, hamster, guinea pigs, mice, etc.) is a very important source of allergen in dust. Contrary to popular belief, animal hair is not the problem. Rather, it is a protein in the urine, saliva and dander of animal that provokes allergy. There are no “nonallergenic” furred pets. Some individual animals produce more allergen than others but there are no “safe” breeds.

The best thing you can do if you are allergic is to eliminate the pet.

Keeping the animal outside is only a partial solution because people who handle the animals outside will bring the allergen in on their clothes.

If you cannot eliminate the pet, try to keep the pet in non-upholstered areas and never let the pet in the bedroom. A HEPA filter in the bedroom may provide some protection.

Bathing the animals weekly may decrease the amount of allergen they produce.

After the animal has been removed, it can take as long as a year for allergen levels in the home to drop significantly, so a good thorough cleaning of the home is necessary after eliminating the animal.

Recently some information has come to light which suggests that if you are not already allergic it may actually be helpful to have cats or dogs in the home. However, if you are already pet allergic having the pets around will only worsen your allergic symptoms.

Indoor Mold can also cause significant allergic respiratory symptoms. Homes with high humidity and/or leaks have a high likelihood of having significant indoor molds. Once these issues have been fixed, it is generally easy to eliminate molds, but if you continue to have problems with water leaks or high humidity, you will have a hard time cleaning up your mold. Use a cleaning solution containing 5% bleach and a small amount of detergent to clean up moldy areas. Performing house dust control measures will help as well.

Ragweed Season is HERE

Ragweed Season

Ragweed Plants Packed with Pollen

Summer fun can turn to fall misery for millions of people who suffer from seasonal allergic rhinitis (hay fever). Sneezing, stuffy or runny nose, itchy eyes, nose and throat, or worsening of asthma symptoms are common in people with undiagnosed or poorly managed hay fever.

The primary culprit of fall allergies is ragweed pollen. A ragweed plant only lives one season, but it packs a powerful punch. A single plant can produce up to 1 billion pollen grains. These grains are very light weight and float easily through the air.

Fall allergy symptoms used to start in mid-August and run through September. In many parts of the country these symptoms now begin in early August and extend through October. Some studies suggest that rising temperatures and higher carbon dioxide levels contribute to longer growth time of allergen-producing plants. In 2023, OAAC reported high ragweed counts beginning in the third week of August. In fact, on August 28, 2023, we had our first ragweed allergy alert day.

Allergies occur when the body’s immune system treats the allergen, in this case ragweed, as a foreign invader. This starts a chemical reaction which produces and sends histamine throughout the blood stream. These chemicals cause allergy symptoms to develop.

Controlling symptoms
Proper diagnosis is the first step in managing your symptoms. An allergist will give a physical exam, ask about your health history and perform allergy testing to determine exactly what you are and are not allergic to.

Although there is no cure, ragweed allergy can be managed to improve the quality of your life.

The best control is to avoid contact with the pollen. This can be difficult, but resources are available. The National Allergy Bureau^TM(NAB) tracks pollen counts regionally to help you plan when you should avoid spending a lot of time outdoors. Remember to follow the OAAC on social media for the OKC area. Our counts are collected from the top of our main office building Monday-Friday by our certified pollen counters.

Talk to your doctor about medications that may provide temporary relief from symptoms. Your allergist/immunologist may also recommend immunotherapy (allergy shots) or sublingual immunotherapy (SLIT) allergy tablets, treatment. This long-term treatment approach can significantly reduce the frequency and severity of symptoms caused by allergic rhinitis.

Did you know?

The tall goldenrod species of ragweed gets blamed for most of the pollen, but a primary cause of allergy symptoms is the tooth-leaved ragweed that lives low in the grass.
• Ragweed can be found in almost all states in the United States as well as in Canada.
• An accurate diagnosis is essential for managing symptoms. Allergy testing performed by an allergist can determine what you are and not allergic to.To the point
Although often associated with hay fever, ragweed can also cause skin conditions such as allergic contact dermatitis and hives.
