Dust allergy: where does it come from and how to deal with it

Why dust allergies aren't just about sneezing

For many, sneezing at home or in the office seems like a normal reaction to an odor or draft. But if it happens every day, accompanied by a stuffy nose, itchy eyes, and fatigue, it's probably a sign of something more serious. allergy to dust. This is a chronic disease that can significantly affect the quality of life and even cause serious complications, including bronchial asthma.

Dust is not just dust from shelves. It is a whole microcosm of allergens that enter the body with the air and cause a hyperreaction of the immune system.

What exactly causes allergies in house dust?

The main dust allergens are:

• House dust mites (Dermatophagoides pteronyssinus, D. farinae) is the main source of allergies. Their waste products (enzymes) cause a strong allergic reaction.

• Mold spores — especially in damp rooms, bathrooms, and kitchens.

• Animal epithelium particles — even without direct contact with animals, the allergen remains in the air.

• Textile fibers, paper microparticles, down and feathers — from furniture, pillows, carpets.

• Food residue in kitchen dust — attract microorganisms, which can also be allergens.

All of these particles are very small in size, which allows them to remain in the air for a long time and penetrate deep into the respiratory tract.

How does dust allergy manifest itself?

Symptoms can range from mild to chronic, especially in individuals prone to allergic reactions or with a genetic predisposition:

• Often sneeze in the morning or when cleaning

• Nasal congestion, runny nose without infection

• Itching in the nose, throat, eyes

• Tearing, redness of the eyelids

• Night cough, shortness of breath, difficulty breathing

• Symptoms bronchial asthma (wheezing, chest tightness)

• Constant fatigue and irritability due to sleep disturbance

Deterioration can be observed in autumn, winter (with dry air and closed windows), as well as in rooms where cleaning has not been done for a long time.

How is dust allergy diagnosed?

To accurately determine the allergen, you need allergist consultation and conducting:

• Mock tests with dust mite extracts

• Immunological blood test (IgE) to specific allergens

• Component diagnostics (determination of the reaction to specific tick proteins)

In some cases, molecular diagnostics are used to differentiate between sensitization and true allergy.

Methods of treating dust allergies

Treatment should be comprehensive and include:

• Avoiding contact with the allergen

  • wet cleaning without brooms and vacuum cleaners without filters

  • removal of carpets, heavy curtains, soft toys

  • using dust covers for mattresses and pillows

  • air purifiers with HEPA filters

• Pharmacotherapy

  • antihistamines new generation

  • nasal sprays with corticosteroids

  • inhalers for asthma symptoms

• ASIT (allergen-specific immunotherapy)
  — the only method that can change the immune response and provide long-term remission. It is administered in the form of subcutaneous injections or sublingual tablets.

Prevention: How to Reduce Allergen Levels in Your Home

• Regular wet cleaning all surfaces

• Washing bed linen at a temperature not lower than 60°C

• Replacing pillows with synthetic ones

• Using air dehumidifiers in damp rooms

• Ventilate the room daily

• Avoiding the accumulation of books, souvenirs, and old things in bedrooms

Dust allergies are not just a seasonal discomfort. They are a chronic condition that requires careful management, the right environment, and modern treatment. By changing the space around you and consulting a specialist, you can not only alleviate the symptoms, but also regain a full life without constant sneezing and fatigue.
