What Is Environmental Control?
Environmental control requires a bit of work on your part - it's not quite as easy as swallowing a pill or getting a shot - but it is the
most effective treatment for allergies. If you can control your environment and avoid your allergens, then you will not experience
allergy symptoms. It's that simple!
Environmental control may involve frequent vacuuming with a HEPA-filtered vacuum cleaner, encasing your mattress and pillows with special
allergy relief bedding, running an air purifier, wearing a mask, or placing a dehumidifier in your basement. Your environmental control plan
depends on the specific allergens to which you are allergic.
What Causes Allergy Symptoms?
Allergy symptoms appear after a sensitive individual is exposed to allergens. The most common allergens are proteins from plants and
animals (although some people may be allergic to certain chemicals). Once an allergen makes its way inside the body, it sets off a
chemical chain reaction within the immune system of sensitive individuals. This chain reaction, which includes the release of histamine
and other inflammatory chemicals, leads to allergy symptoms - sneezing, watery eyes, congestion, etc.
How Do I Discover My Specific Allergens?
Before you can formulate an environmental control plan, you must know the substances that cause your allergy symptoms.
You should visit an allergist or ENT physician for allergy testing. In the most common method of allergy testing, an allergy
technician pricks the skin with a tiny needle to insert a small amount of the allergen. If the patient is allergic, then the site
of the skin prick will become red and swollen.
As another option that's more cost-effective and convenient, you can use MyAllergy Test in your own home. This easy-to-use
kit allows you to collect a sample of blood (using a finger stick lancet) and send it to a lab for allergy testing. MyAllergy Test shows if you're allergic to timothy grass, bermuda grass, mountain cedar, short ragweed, mold, milk, egg whites, wheat, cat dander, and dust mites. If you want more extensive testing, you should make an appointment with an allergist.
Once you know your specific allergens, then you can start implementing environmental controls to help you avoid exposure to your allergens.
Dust Mite Allergy
in a microscopic sci-fi movie, dust mites are everywhere. They can live inside automobiles,
deep within carpet fibers, and on furniture. Since dust mites feed on dead human skin, they tend to hang out where the shed skin collects: in the fibers of
your bedding, mattress, and pillows. That's why it's vitally important to encase your bed with allergy relief bedding, also known as
dust mite encasings. These encasings will keep dust mites from invading your bed.
See the Allergy Bedding Buying Guide to learn more.
You should also vacuum frequently with a HEPA vacuum cleaner. Vacuuming alone
will not suck up all the dust mites, but it will take away their food. To kill dust mites in carpet, use
anti-allergenic carpet powders and sprays.
We also recommend using anti-allergenic laundry detergents and additives
to kill dust mites and denature allergens in your laundry, especially if you normally wash your laundry in cold water. (Water must be very hot
in order to kill dust mites, but you can kill them in a cold water wash by using
de-mite laundry additive or
If you have a dust mite allergy, you should monitor your relative humidity. Dust mites like warm, humid environments, and they cannot thrive if you keep
the relative humidity below 50 percent. Monitor your humidity with a humidity gauge.
If necessary, you can lower the humidity in your home with a dehumidifier.
See the Dehumidifier Buying Guide to learn more.
Finally, although an air purifier won't eliminate the
actual dust mites, it will eliminate excess dust in your home. To reduce dust mite populations, it's important to keep your home
free of dust and clutter. If you can, replace carpet with hardwood floors and low-pile area rugs.
Stuffed animals also harbor dust mites. You can kill dust mites on small items like stuffed animals by placing them out in the sun for
several hours or by putting them in the freezer over night. Or, you can buy washable toys like Gund Stuffed Animals.
As with dust
mites, it's impossible to get rid of every single mold spore in your home. They're everywhere! However, using environmental control measures,
you can greatly reduce the number of mold spores in your home and thereby reduce the frequency and severity of your allergy symptoms.
Like dust mites, mold requires a warm, humid environment for growth.
Monitor the humidity in your home with a humidity gauge, and
keep the humidity below 50 percent using a dehumidifier.
For protection while you're sleeping, Allergy Armor allergy relief bedding
features a special antimicrobial finish that prevents mold growth.
Use M-1 Sure Cote Mold & Mildew Resistant Sealant to clean up mold around your home and prevent future growth. AllerMold and
Vital Oxide are two additional household cleaners that are
effective against mold but safe for your family and the environment.
Be careful when cleaning mold! If the growth is significant, you'll want to wear a mask,
along with gloves and goggles.
HEPA air purifiers and HEPA vacuum cleaners also capture mold spores and remove them from
your environment. For more information, see the Vacuum Cleaner Buying Guide
and the Air Purifier Buying Guide.
Pet Dander Allergy
already discussed several products that will help you avoid pet dander in your home; these products include allergy relief bedding,
air purifiers, and HEPA vacuum cleaners. Allergy Armor Ultra bedding,
for instance, blocks animal dander from your bed. Other products specially made for pet allergies include the Dyson DC17 Animal vacuum and the
Austin Air Pet Machine air purifier.
If you own a pet, we also offer items to help you keep your pet's dander to a minimum, including the
Dyson Groom and
Ecology Works Pet Allergy Shampoo. See all
Pet Allergy products for more suggestions.
Of course, if you're severely allergic to a specific animal, the best advice is to stay away from that animal. If you cannot avoid spending time
with an allergenic animal, try avoid touching your face, and wash your hands (or better yet, shower) as soon as possible. And keep all pets out of your bedroom!
main problem with pollen allergy is that you can't go outside and vacuum up all the pollen, nor can you stick an air purifier in your backyard
and expect it to have any affect on the pollen level. When dealing with a pollen allergy, it's best to wear a
mask outdoors. Watch your local pollen count and try to stay inside when the
pollen counts are high. Once you get inside, shower as soon as possible.
Indoors, you can use HEPA vacuums and air purifiers to capture pollen grains. Be aware that pollen will find its way inside your home any
time a door opens or window opens. If you want to get some fresh air without the pollen, put a
Safeguard Window Filter on your window.
Sinus and nasal irrigation products also work well for pollen allergy sufferers because the saline washes away pollen grains in the nasal
passages. The SinuPulse Elite is the world's most advanced nasal irrigation
system, but a simple neti pot works well, too. See our
Seasonal Allergy Solution Guide for more information about pollen allergy.
