If cold, wintry weather is keeping you indoors, remember: Year-round, that's home to many of the peskiest allergy and asthma triggers, according to the
1. DUST MITES
Microscopic insects called dust mites are the most common allergy and asthma symptom trigger, according to the
To ward off dust mites, allergists recommend purchasing allergen-proof encasings for pillows, mattresses, and box springs, and washing linens in 130-degree temperatures every seven to 10 days.
"Any place you find people where it's not supercold or really dry, you can have dust mites," White says. Unlike bedbugs, dust mites don't bite, so you won't wake up with puncture marks on your skin. "It's largely a respiratory phenomenon," says Clifford Bassett, chair of the AAAAI's Public Education Committee.
When it comes to cleaning, have someone else handle the vacuuming, or wear a mask. And use a vacuum that contains a HEPA filter or double-layered bag. Since stuffed animals collect dust mites, too, you'll need a simple way to keep your child's favorites trouble free.
"Take the stuffed toy, put it in a freezer bag, and then put it in the freezer for three to five hours per week," Bassett says. Freezing the toy kills the dust mites. When purchasing other types of toys, stick with products that are washable or easy to wipe off.
2. PETS
The dander shed by furry friends can cause symptoms in susceptible people. But for reasons not completely understood, some allergic people are OK around certain breeds. While there is no such thing as a hypoallergenic dog, some breeds, such as poodles and Portuguese water dogs (the breed President Obama's family chose because of daughter Malia's allergies), produce less dander.
To test how you or your child fare around a particular breed, visit a friend or family member who has a pet to see how you feel, suggests Martha White, an AAAAI fellow and research director at the
3. MOLD
Indoor mold tends to grow in damp, dark environments, such as basements or showers and bathtubs, says Robert Fisher, the medical director at a Wisconsin-based practice called
"Don't rent in the basement, and don't put a bedroom in the basement," White says. Also, think about putting tile down as basement flooring rather than carpet. "If there's going to be water leakage," White says, "then carpet gets wet and moldy, so you want a floor that will dry easily."
Mold growth should be cleaned thoroughly using water, detergent, and 5 percent bleach, if needed. If mold spreads over an area larger than 10 square feet, the help of an indoor environmental professional may be needed, the AAAAI says.
4. COCKROACHES
Cockroaches, an issue mostly in cities and the southern United States, are believed to play a large role in asthma in inner-city populations, according to the
Don't think that because you saw one roach in your home and killed it that your problem is solved.
"If you see evidence of a roach, that usually means there's a lot in the house," White says. If you live in an apartment or condo, call your landlord or condo association to arrange extermination of your entire building, she advises. Sometimes people with allergies are hesitant to have extermination done because they're worried about the impact of chemicals on their health. "But if they're allergic (to roaches), they should get it done," she says--while family and pets are out.
Other steps to take, advises the AAAAI: Block off cracks and crevices in the wall or windows. Keep food in containers with lids, put away your pet's dishes, clean up after meals, take garbage out promptly, and fix leaky faucets or pipes because roaches need water to survive. Wash dishes soon after eating, and clean under toasters, refrigerators, and stoves to get rid of crumbs.
5. POLLEN
Many people don't think of pollen as having an impact indoors. But "if you're outdoors during nice weather, you can bring it in on your clothes or shoes," Fisher says. Pets can bring pollen into the home, too, leading some people to assume they're allergic to their pets when in fact they're actually allergic to ragweed or another type of pollen.
To combat this problem, consider wiping pets down when they return from outdoors, keep windows closed in the home and run air conditioning during warmer weather, and change clothes and shoes immediately after returning from outdoors. Also, an air purifier with a HEPA filter can clean the air and keep about 80 percent of pollen out of the home, Fisher says.
6. CIGARETTES
While not a traditional allergen, cigarette smoke is often an irritant for people with asthma and allergies. Secondhand smoke, which irritates the already inflamed bronchial passages in asthmatics, can cause asthma attacks and worsen the severity of the attacks, according to the
Moreover, studies have shown that "exposure to tobacco smoke has incredible impact on increasing risk of asthma in kids," Bassett says. So allergists recommend that parents avoid smoking around children altogether, both at home and in the car. It's thought that because kids are still developing, they're more susceptible to the effects of smoke, and they may breathe more rapidly, causing them to take in more smoke than adults.
