Allergic sensitivity is an immune system reaction to an alien "Invader", a substance that is not native to your body. Exposure to the invader, an allergen that triggers the reaction.
When the allergen particles coming to rest in the linings of the eyes, nose and respiratory tract of a vulnerable person may be an allergic reaction occur.
When the immune system has been "sensitized" to a specific invader, it overreacts to the intruder, this overreaction to a harmless substance known as hypersensitivity or allergic reaction.
This reaction sets in motion a series of responses, which culminate in the release of chemicals called "mediators." Histamine is an example of a mediator.
The effects of mediators on cells and tissues that causes allergic symptoms.
Mites
Dust mites are common indoor allergens. Can be found in most homes, usually on the beds and bedding, upholstered furniture, fabric or other material.
Often when people think they are sensitive to dust, are actually sensitive to dust mites and particles of debris and fragments of dead mites can be found in house dust.
Animal dander
For some people, pets trigger allergic reactions. They simply can not be around animals such as dogs, cats, gerbils, hamsters and other fur without developing unpleasant symptoms such as sneezing, stuffy nose, itchy eyes and asthma.
Contrary to what many believe, an allergic reaction to animals is not due to hair.
An allergic reaction is actually caused by substances in animal saliva, urine, and especially the scales.
Dandruff is flakes of dead skin (like dandruff), which detaches from the skin of the animal.
Allergens have become split hairs or skin, urination, or the animal licking or scratching itself, once dry, the allergens are airborne, where they referred to other parts of the house dust.
A variety of small animals, which are popular, because the house pet cause allergic reactions.
Animals such as dogs and cats are more likely to cause allergic reactions.
Birds can also cause reactions, but less often than other animals.
Animals such as fish, reptiles and amphibians rarely cause allergic reactions.
Can trigger an allergic reaction to one of the following:
Directly affect the animals
Being at home with the animal
Being in an area covered with furniture, carpets, bedding, curtains, clothing, bedding or cages of animals, even the counters and walls, where the animal is allergen landed
Being in an area covered with another person whose clothes are allergens
Cleaning pet beds, cages or litter
Touching toys, bedding, towels, or other animal that has touched
Moulds
Molds are a type of fungus that has no stems, leaves and roots.
Mussels usually live outdoors, but you can usually find in almost any indoor environment. They can trigger hay fever and asthma, and reproduce by releasing spores into the air, floating around until they find a hospitable environment.
They pass easily through doors and windows open and move inside, especially when there is excess heat and moisture. To develop and produce mold. Many of us have seen mold growing in the shower.
Mold is not always visible, but can grow in unseen areas of the house, floor materials, such as under and behind the walls.
To grow, mold requires water, which may be liquid water from the leaking pipe or roof, or a pool of condensation on the windows o.
It also requires something to grow, and the mold is not picky, but is expected to grow wood, sheet rock, or fabric.
As it grows, mold release more spores, many of which have become part of house dust.
Although molds can trigger allergic symptoms, like any other allergen, rarely cause serious health problems, except for people who are severely immunocompromised, or chemotherapy.
Cockroaches
Most of us do not want to think of insects in our homes, especially cockroaches, but they are a fact of life. If you live in a crowded urban area, an old multi-family dwelling, or a warm climate, such as the U.S. South, you will almost certainly cockroaches living in your home, even if you can not see them.
Cockroaches like damp places where food is available.
Even if the kitchen is their favorite room, you can find almost anywhere in the house.
When they die, usually not in sight, their bodies are dried and broken. These body parts, and dry waste, become part of house dust.
