What is the cause of dust and pet hair allergy?
In case of allergy to dust and hair, the body reacts not to the irritants themselves, but to
the microorganisms that live in them. What we call dust is a mixture of various microscopic
particles. It may contain small scales of human epithelium, pet hair, food scraps, flower
pollen, textile fibers from linen and clothing, excrement of rodents and insects, spores of
molds and yeasts, bacteria, and even living creatures – microscopic dust mites. Their size
is only from 100 to 300 microns. Saprophytes feed on dead human skin scales. And since a person
"sheds" about 2 kg of such particles per year, mites thrive in our apartments.
Any items in which harmful particles accumulate (carpets, pillows, blankets, mattresses,
bookshelves with long-standing collections of works) can cause allergy symptoms.
