Dust Allergies & It’s Triggers

Dust allergies also make it difficult to breathe and may trigger asthma symptoms, such as wheezing, coughing, tightness in the chest and shortness of breath. Dust also just makes some people itchy. People with dust allergies often suffer the most inside their own homes or in other people’s homes. Oddly enough, their symptoms often worsen during or immediately after vacuuming, sweeping and dusting. The process of cleaning can stir up dust particles, making them easier to inhale.

Dust mites—sometimes called bed mites—are the most common cause of allergy from house dust. Dust mites live and multiply easily in warm, humid places. They prefer temperatures at or above 70 degrees Fahrenheit with humidity of 75 to 80 percent. They die when the humidity falls below 50 percent. They are not usually found in dry climates. Dust mite particles are often found in pillows, mattresses, carpeting and upholstered furniture. They float into the air when anyone vacuums, walks on a carpet or disturbs bedding and they settle once the disturbance is over. Dust mites are a common cause of asthma in children.

A house does not need to be visibly dirty to trigger a dust mite allergy reaction. The particles are too tiny to be seen and often cannot be removed using normal cleaning procedures. In fact, a vigorous cleaning can make an allergic person’s symptoms worse.

Cockroaches live in all types of buildings and neighborhoods. Some people develop allergy symptoms when they are around cockroaches. Tiny particles from the cockroach are a common component of household dust and may be the true cause of a dust allergy.

Mold is a fungus that makes spores that float in the air. When people with a mold allergy inhale the spores, they get allergy symptoms. There are many different kinds of mold—some kinds you can see, others you can’t. Molds live everywhere—on logs and on fallen leaves, and in moist places like bathrooms and kitchens. Tiny mold particles and spores are a common component of household dust and may be the true cause of a dust allergy.

Pollen comes from trees, grasses, flowers and weeds. People can be allergic to different types of pollen. For instance, some people are allergic to pollen from only beech trees; others are allergic to pollen from only certain kinds of grasses. Pollen is a common component of household dust and may be the true cause of a dust allergy.

Animal hair, fur and feathers. Pets can cause problems for allergic patients in several ways. Their dander (skin flakes), saliva and urine can cause an allergic reaction, especially when combined with household dust. In households with birds, feathers and bird droppings can also become embedded in household dust and cause problems for people who are allergic to them.
