Environmental Control for Indoor Allergens

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.

2020 Allergy Capitals™ Report Ranks the Most Challenging Cities in the U.S. for Allergies; Oklahoma City named 9th out of 100

The Asthma and Allergy Foundation of America (AAFA), the premiere patient advocacy organization representing more than 60 million Americans with asthma and allergies, just released its annual Allergy Capitals™ report for 2020. The report identifies the most challenging places to live with spring and fall allergies in the top 100 metropolitan areas in the U.S. Richmond, Virginia, takes the top spot based on higher-than average spring and fall pollen scores, higher-than-average medication usage and availability of board-certified allergists in the area. The top 10 Allergy Capitals for 2020 are:

1.Richmond, Virginia 2. Scranton, Pennsylvania 3. Springfield, Massachusetts 4. Hartford, Connecticut 5. McAllen, Texas 6. New Haven, Connecticut 7. San Antonio, Texas 8. Bridgeport, Connecticut 9. Oklahoma City, Oklahoma 10. Pittsburgh, Pennsylvania. Tulsa was named 23rd.

“For more than 50 years, the prevalence of allergic diseases has risen and it’s no coincidence that during the same time, pollen seasons have become stronger and longer due to warmer temperatures,” says Kenneth Mendez, AAFA CEO and president. “The Allergy Capitals report helps raise awareness about the impact of seasonal allergies, how people can prepare and start proper treatment. Local communities can also use the report as a tool to identify how to better meet the needs of their residents living with allergies and allergic asthma.”

Seasonal nasal allergies cause runny and congested noses, inflamed sinuses, relentless sneezing and other symptoms each spring through fall. Pollen can also trigger asthma attacks. Tree pollen season starts as early as January in some parts of the U.S. and continues through summer. In the fall, weed pollen – especially ragweed pollen – is responsible for symptoms. But relief is possible with the right treatment and by managing contact with pollen.

“You are not alone in dealing with allergies,” said Laura Chong, M.D., Oklahoma Allergy & Asthma Clinic Board-Certified Allergist. “Oklahoma City consistently remains in the top allergy and asthma capitals each year. You can take steps to limit your exposure to seasonal allergens like pollen; however, it is impossible to avoid pollen completely. It’s important to talk to your allergist about an allergy treatment plan to keep your symptoms under control.”

Treatment options can include over-the-counter or prescription allergy medicines. Allergy immunotherapy can help reduce or prevent allergy symptoms. These treatments are most effective if they are started before the allergy season begins.

See the full 100-city ranking at allergycapitals.com. The report lists overall rankings and breaks down a seasonal ranking for spring and fall.  Watching daily pollen and mold reports can help those who are pollen allergic plan their day and make sure they are taking their medications.

A board-certified allergist can diagnose allergies, and determine the specific triggers that cause them, through simple tests. The allergists at Oklahoma Allergy & Asthma Clinic evaluate and manage patients of all ages.  The main clinic is on the Oklahoma Health Center campus.  For patient convenience, satellite offices are located in Edmond, Norman, Midwest City and Yukon.
