Allergic Triggers

Airborne allergens trigger asthma symptoms by entering the lungs when you breathe; other allergens are ingested.

Dust mites are microscopic insects that can live in carpeting and cloth (curtains, bedding, even stuffed toys).

• Use special dust-proof covers on your mattress and pillows, or wash the pillow each week in hot water (more than 130 degrees Fahrenheit).
• Wash your sheets and blankets each week in hot water.
• Remove carpets where possible, especially in the bedroom.
• Avoid sleeping on cloth-covered furniture or cushions.
• Keep stuffed toys out of the bed or wash them weekly in hot water.
• Clean air conditioner filters frequently.
• Try to get someone else to vacuum for you; avoid rooms while they are being vacuumed and for a short time afterwards.
• If you vacuum, use a dust mask, double-layered or microfilter vacuum cleaner bag, or a vacuum cleaner with a HEPA (high efficiency particulate arresting) filter. Vacuums with HEPA filters are more effective than regular models at removing pollen, mold, dust and other particles.

Some people are allergic to dander, the skin flakes or dried saliva from animals.

• Keep furred or feathered pets out of your home.
• If you have a pet, keep it out of the bedroom and keep the bedroom door closed.
• Remove carpets and cloth-covered furniture from your home. If you can't, try to keep the pet out of rooms containing these items.

Many people are allergic to cockroach droppings and dried cockroach remains.

• Keep food out of the bedroom
• Never leave food out in the open; keep food and garbage in closed containers.
• Kill cockroaches with traps, baits, powders, etc. If you use a spray, stay out of the room until the odor disappears.

Molds can be a problem in bathrooms, kitchens and basements, especially when humidity is high.

• Fix leaky pipes, faucets or other water sources.
• Clean moldy surfaces with a bleach product.
• Use a dehumidifier in damp areas; remember to empty the water and clean the container often.

Keep away from foods that cause asthma symptoms.

• From 3 percent to 8 percent of children have reactions to some foods. Only 1 percent to 2 percent have true food allergies. Some children seem to grow out of their sensitivity to certain foods, often by age 4.
• Avoid foods containing additives such as sulfites or MSG if you have identified them as triggers.

Talk to your health care provider about alternatives to medications you're allergic to; for example, aspirin is an asthma trigger for some people.

Pollens can be a problem for many allergy sufferers. If you are affected:

• Keep your windows closed whenever possible.
• Stay indoors with windows closed during peak pollen times.
• Ask your doctor about taking or increasing your anti-inflammatory medicine before your allergy season begins.
