Information
- The Environmental Protection
Agency (EPA) has stated that Asthma is the leading chronic illness of children
in the US and is the major cause of school absenteeism for a chronic illness.
Every year there is an increase in the number of deaths due to asthma and the
amount of Americans that have been diagnosed with asthma also increases.
According to the American Lung Association, about 15 million Americans suffer
from asthma and it is the seventh highest chronic condition in America. A 61%
increase in asthma rate, from 1982 to 1994 was reported by the Centers for
Disease Control and Prevention. Asthma can be a very serious illness and kills
over 5,600 people a year. We have more detailed information on
allergens and indoor air pollutants in our
Asthma
& Allergies and
Indoor
Air Quality sections of our
Education
Center.
Allergies, according to the
American Academy of Allergy and Immunology, affect one out of six Americans. An Allergy
is a response to a substance, called allergens, that produce a
reaction in the body. When the immune system is exposed to allergens, it
produces antibodies which attach themselves to certain cells in the body called
"mast cells." These mast cells see the invading particle as a
threat and release substances such as Histamine to destroy the intruder
particle, but these substances also produce undesirable allergic reactions. When
the reaction takes place in the nose and sinuses, it is called Hay Fever or Allergic
Rhinitis. When the reaction to allergens occurs in the skin it is
called Hives. An allergic reaction that occurs over the whole body can be life
threatening and is called Anaphylaxis. A reaction in the stomach is a Food
Allergy and when an allergic reaction due to allergens happens in the lungs, it
is called Allergic Asthma. Asthma is a chronic illness that
causes breathing problems and is considered a lung disease. It is still unknown
what exactly causes asthma, but it is known that once you have it, your lungs
react to "triggers" which can start an asthma attack.
Some common
"triggers" of asthma and allergies include:
- Cold air.
- Tobacco and wood smoke.
- Strong odors or chemical
fumes such as paints , hair sprays and perfumes.
- Allergens such as dust
mites, pollen, animal dander, pollution and molds.
- Respiratory illness such as
the common cold or influenza.
- Certain drugs.
- Substances that come in
contact with the skin such as cosmetics, perfumes, hair dyes and
chemicals.
- Foods such as cow's milk,
eggs, chicken, shellfish, peanuts, wheat products and various chemical
food additives and preservatives.
When changes occur in the lungs,
the air tubes narrow and make it difficult to breathe. This condition can
develop very quickly or take days to manifest itself. These attacks may have
various levels of severity.
An
allergic reaction in the lungs, or asthma attack, causes three things to happen:
- Cells in your air
tubes (bronchial tubes) make more mucus than usual which
tends to clog up the tubes.
- The air tubes tend to
swell up.
- The muscles in your
air tubes begin to tighten up.

The indoor home environment
can contain many allergens from organic and inorganic sources and they can
become airborne as particles, vapors and gasses. These allergens can be derived
from many sources such as entering from the exterior of the home, the building
structure, furnishings, occupants, animals, plants and fungi.
The most common household
indoor allergens include:
- Dust Mites
- These are microscopic creatures related to the spider family. They
are invisible to the human eye and are about 0.3mm in length. They live on
human skin flakes and require water vapor to survive. They are most
prevalent in the bedroom where millions can exist in your mattress,
boxspring, pillows and comforters. They are also found in upholstered
furniture, carpeting and other fabric items. Dust mites produce 20 or more
fecal pellets per day, which is the primary allergen to humans. We
inhale these allergens while sleeping and during periods when these particle
become airborne such as when vacuuming and disturbing the infested fabrics.
-
- Molds
- Molds are
living organisms that proliferate in environments that have warm
temperatures and excessive moisture. These areas include damp
basements, drip pans under refrigerators, bathrooms and places where
standing water is present such as common humidifiers. Molds release spores
into the air in an effort to reproduce and these spores are inhaled and
cause allergic reactions.
-
- Animal Dander
- This is a combination of dead skin cells, saliva and sebaceous gland
secretions from animals. Dead skin cells in animals flake off as the skin
regenerates itself and saliva from the animal is applied to the skin from
self grooming. This animal dander becomes dry and circulates in the air and
throughout the house. Inhalation and/or skin contact can cause allergic
reactions.
-
- Chemical Vapors and
Gasses
-
A variety of chemicals and gasses are present around the home that can
trigger allergic reactions. Gasses in tobacco smoke and wood smoke from
fireplaces along with vapors from building materials and home furnishings
may be present in your indoor environment. Chemically laden
household cleaning products and personal care products may produce gasses
and vapors that may result in allergic reactions.
-
- House Dust
- A mixture of fibers from carpets, furniture and clothing that becomes
mixed with sand particles, human skin flakes, food debris, grit and various
microorganisms. These particles, both large and small, are inhaled into the
lungs where they may become lodged there and cause airway obstruction or
allergic reactions that produce restricted breathing
-
Many
common allergic reactions include:
- Year-long Hay Fever
Symptoms.
- Asthma Development.
- Chronic Sinusitis.
- Sneezing
- Runny, Blocked or
Itchy Nose
- Itchy Palate
|
- Asthma attacks.
- Eczema
- Headaches
- Itchy Eyes
- Wheezing
- Night Time Cough
|
-
- Some important steps
you can take to reduce your allergen exposure in your home include:
- Use a central vacuum system
(exhausts outside) or portable sealed HEPA
Vacuum to prevent allergens from being dispersed into the air.
- Encase your bedding with Dust
Mite Barriers that prevent their proliferation in an area that
you spend 1/3 of your day.
- Wash bedding fabrics weekly in
hot water (minimum 130° F).
- Use surface treatments for Dust
Mite Control, Animal
Dander Control, Mold
Control and Dust
Control that will reduce your exposure to these allergens
throughout the home.
- Don't allow pets in the
bedroom.
- Reduce your exposure to
chemical gasses and vapors with natural ingredient based
Household
Cleaners and Personal
Care Products.
- Reduce your exposure to
airborne particulates with the use of a portable Air
Purification Unit or a central air filtering system.
- Increase low moisture levels
in the home and prevent the release of mold
into the air when using humidifiers by using Germ-Free
Humidifiers that kill mold and bacteria before moist air is
released into the room.
- Remove the build-up of molds
and bacteria and clean your home without irritating chemicals with a home Steam
Cleaning System.
- Control excess indoor humidity
with adequate ventilation and the use of dehumidifiers and air conditioners
as necessary.
