microscopic particles in huge numbers are in
apartments, houses, on the streets of any cities, towns, etc. Even with
slight impact on the “dusty” area, particles
lifted into the air and can be inhaled by humans. Most of
population will not notice their presence in the upper respiratory tract
(nose, oropharynx) or react with several episodes of sneezing.
However, in the body, 9-14% of people will develop an inflammatory response.
Despite the fact that almost all people are equally in contact
with dust, allergic diseases do not occur in all. AT чем причина

How to find out the propensity to allergies? AT первую

brothers and sisters, older generations). Also существует лабораторный
method of identifying allergies, even before the first symptoms. it

quite rarely, because it does not allow to determine the substance
causing disease. IG E rate depends on age:
- Newborns (first month of life) – up to 2 kU / l;
- 2-6 months – up to 10 kE / l;
- Up to a year – less than 20 kE / l;
- 2-10 years – no more than 60 kE / l;
- Above 12 years old – less than 100 kE / l.
It should be noted that dust can be household (located in
within the premises) and production (source – any exhaust
gases, factory emissions, etc.). They существенно отличаются по
составу, однако симптомы аллергических болезней, which они
cause almost identical.
How does an allergy manifest itself? There are 6 main forms with
various symptoms. Which of them will be observed in a patient
depends on the amount of allergen (in this case dust) and the place
where it goes (eyes, skin, or respiratory tract). Any
allergic disease flows periodically – exacerbations are replaced

Allergies always occur periodically – periods of complete
health are replaced by exacerbations. To prevent most of
them, it is enough to follow simple recommendations:
- Reduce the likelihood of contact with dust (described in detail at the beginning
section of treatment). Let us list again the most important events:
- Regular wet cleaning in the apartment / house wiping all
- Constant airing and humidification of the air;
- Replacing pillows, blankets, mattresses from natural materials to
- Regular changing and washing of bed linen;
- If there are carpets on the wall, they are strongly recommended.
- Floor carpets can be left if they are done regularly.
- Regular wet cleaning in the apartment / house wiping all
- In the presence of allergies mainly on “street” dust,
consult a doctor and undergo a preventive course of treatment in the spring and
