Your own home can turn into a trap, because the household allergens is difficult to determine, and to avoid contact with them is virtually impossible.
While many household allergens can cause allergic symptoms, the main culprit is the domestic house dust allergy. What is house dust?
- The quality and quantity of house dust depends on the type and age of the premises, the temperature and humidity of the air in indoor objects (any, from food to clothing), and the residents of the house (humans, animals, plants).
- Dust, even in small quantities, is in each house, regardless of how often it is removed carefully.
- House dust is carried by air through the mixture containing fine particles of soil and plant material from the room or from outside, skin particles man and animal hair, fibers, fabrics, mold spores, dust mites, fragments of dead insects and their waste, food particles and other debris .

pets, cockroaches, and mold.
Unlike seasonal allergies, such as hay fever, allergies household can continue throughout the year. Exposure to household allergens can cause or exacerbate asthma symptoms, depending on individual sensitivity of each person.
- Household allergies, usually exacerbated in late summer, when most dust mites.
- Symptoms of household allergies are most pronounced in winter when the windows are closed, and people have to constantly contact with allergens.

Causes of household allergies
Allergic sensitivity - this is a reaction of the immune system
The immune system - how it works?
a substance which is not natural for your body and regarded them as "aggressor". Under the effect of this substance (allergen) in the body of histamine release reaction occurs, and this leads to the appearance of the characteristic symptoms.
When the allergen particles fall into the eye mucosa, nose or respiratory tract, an allergic reaction.
- If the immune system has already passed the "sensitization" (the production of antibodies to the allergen at the first contact with him), to the specific "aggressor", she begins to actively protect themselves from it; This reaction to a harmless substance known as hypersensitivity or allergic reaction.
- An allergic reaction is initiated by a number of other reactions that lead to the release into the blood of chemicals called "mediators" (mediators) such as histamine.
- Under the influence of mediators and cells and tissues of allergic symptoms occur.
- Dust mites - the most common household allergens. They can be found in most homes, usually in beds and bedding, upholstered furniture, clothing, or any tissue.
- Those who argue that is sensitive to dust are actually sensitive to dust mites and their waste, as well as particles of dead dust mites, which are found in house dust.
Mould - This fungus having no stems, leaves or roots of forming coating on various materials.
- Mold, are usually the most common in nature, but can be found in virtually any environment. It can cause allergic rhinitis

and asthma, and reproduce by spores that are in the air as long as find a favorable environment for growth.
- Disputes easily pass through the open doors and windows and settle in areas, particularly where there is excess heat and humidity. The warm and humid environment (e.g., in a shower room) they grow into mold.
- But mold is not always possible to see with the naked eye; It can grow in hidden areas of the house, such as under floors and behind walls.
For the growth of mold requires moisture, such as a water pipe or a leaky roof, or condensation on a window pane.
- Once the desired surface mold growth. Most often, mold grows on wood, gypsum cement slabs or tissue.
- With the growth of mold releases more spores that fall in house dust and cause allergies.
- Despite the fact that the mold, like any other household allergens can cause allergic symptoms, it rarely leads to serious health problems, except when allergic to mold combined with weakened immune systems
Immunity - types and characteristics in children in adults
We do not like to think that in our house can live insects, especially cockroaches, but the fact remains. If you live in a densely populated urban area, in an apartment building, you will probably ever encountered with cockroaches.
- Cockroaches like warm moist places where there is food.
- Favorite place of cockroaches - the kitchen, but they can also be found in other rooms.
- The bodies of dead cockroaches dry out and crumble into small particles that fall in house dust and cause household allergens.
