Dust Mite Allergies in Children and Adults: Symptoms, Manifestations, and Advice

One of the most widespread allergies, besides pollen allergy, is allergy to dust mites. Unfortunately, this type of allergy is not seasonal but troubles allergics throughout the whole year, especially during their stay at home. Dust mite allergy can make a person despise the place that is supposed to be the most pleasant for us - our bed.

Dust mites can trigger allergies in both children and adults, causing various symptoms and manifestations that affect many aspects of daily life. Understanding dust mite allergy symptoms in adults and kids is crucial, as these reactions can range from rashes, respiratory issues, to skin manifestations like dust mites allergy rash. Identifying the appearance of these microscopic organisms and the impact of humidity on their living conditions and reproduction is key to managing and mitigating their effects. This article delves into the nuances of dust mite allergies, exploring symptoms, manifestations, and offering advice on how to effectively handle these common allergens.



Where Do Dust Mites Come From and How to Detect Their Presence?

Unfortunately, dust mites are present in all households, even though they are not visible to the naked eye. The households with higher relative air humidity of over 50% usually have the most dust mites. These tiny creatures love moisture and darkness, so they are most commonly found in blankets, pillows, and especially mattresses. There, they are given daily food - they feed on the remnants of our skin. 

Symptoms and Manifestations of Dust Mite Allergy

If you or someone in your family suffer from any of the following symptoms in the long term, then pay attention. Dust mite allergy can be the cause of these problems:

  • stuffy nose
  • chronic rhinitis
  • cough
  • increased morning fatigue and swollen face
  • repeated sinus or nasopharynx inflammations
  • repeated middle ear inflammations
  • atopic eczema, especially in small children

Untreated Allergic Rhinitis Can Lead to Asthma


Untreated allergic rhinitis can lead to bronchial asthma. Worsening symptoms:

  • difficulty breathing with possible chest pressure
  • dry cough, wheezing

Mites - Allergy: Is a Particular Season More Significant for Dust Mite Allergies?

Allergies to dust mites are a year-round issue, but some periods tend to worsen their symptoms. Especially during early autumn when homes are less ventilated and more heated. Higher temperatures also improve conditions for mites to thrive.


How to Diagnose Dust Mite Allergies?

If you want to be sure whether you have a dust allergy, you can perform a home allergy test or visit an allergist. The diagnosis process at the doctor's office includes:

  • A detailed analysis of symptoms, previous treatments, environment, and lifestyle.
  • Skin tests - applying allergen extracts to the inner forearm to determine the allergen(s) causing the allergy.
  • Possible blood tests to complement and confirm the diagnosis.

How to Get Rid of Dust Mites?

Dust mites live and breed in bedding, sheets, and mattresses. Each mattress can house several million dust mites. Studies have shown that after two years of use, regular pillows consist of 10% dust, where mites live. The allergen for humans is not the mite itself, but its excrement. Not a pleasant thought, right?

Dust Mites Prefer Humid Air - Maintain Lower Air Humidity at Home

One of the most significant moments for dust mite allergy sufferers was in 1967 when Professor Reindert Voorhorst from University Hospital Leiden (now Leiden University Medical Center) and his colleagues discovered that dust mites were the main source of allergies in common household dust (Voorhorst et al. 1967). Over the next few years, scientists found that dust mites had a definite preference for humid and stuffy air. Therefore, dehumidifiers are essential for allergy sufferers.

On closer examination, it was found that the tiny bodies of mites consist of about 75% water, and their survival depends on maintaining a high water content. Mites, therefore, obtain water vapor from the air. A decade after Voorhorst's study, several studies conducted in mild climates across the United States showed a direct correlation between the humidity level in local homes and the number of mites. In other words, the moister the air in the house, the more mites were present.

Conversely, houses in drier climates had very few mites. As soon as the humidity increased in homes with lower humidity, the number of mites also increased.

Studies have shown that an average mite dies from dehydration in just five to eleven days if the relative humidity of its environment is maintained at 50% or less. Scientists also found that removing water from the environment works much better than several actively toxic pesticides.

Is Washing Effective in Mite Eradication?

You might think that regular washing and laundering at 60°C (140°F) will protect you. Unfortunately, it's not that simple. Although washing at higher temperatures will temporarily kill the mites, their bodies become food for another colony that will breed in your pillows and mattresses. It's a never-ending cycle. The presence of these tiny arachnids is a common feature in every household, and they float in the air everywhere. However, what you can influence is their quantity. How? Primarily through proper prevention. 

How to Prevent Dust Mite Overpopulation?

The best option for allergy sufferers is prevention to avoid dust mite overpopulation. Ideally, follow these recommendations:

  • Keep the bedroom clean.
  • Regularly ventilate the space.
  • Maintain a cooler environment - ideally around 18°C (64°F).
  • Maintain lower air humidity below 50% using dehumidifiers.
  • Use barrier beddings and barrier mattress covers with a nanofiber membrane.
  • Avoid having carpets in the bedroom.
  • Use an air purifier.


Czech Nanofibers Won't Let any Mites Through

Barrier covers and bedding with a nanofiber membrane, which is, by the way, a Czech invention, act as an excellent mechanical barrier for mites. They can significantly improve the sleep quality and overall life of allergy sufferers. Imagine the structure of the membrane as a very dense net that doesn't allow mites to pass through, preventing their multiplication. The advantage is that the bedding and covers still allow air circulation, making them very comfortable.


You can either get special mattress covers and beddings and then use regular beddings on top. Covers are the most cost-effective solution and can remain functional for many years with proper maintenance. If you wash your regular blankets and pillows and cover them with barrier covers, you will reduce the concentration of mites in your surroundings.

Alternatively, you can invest in mite-proof duvets or pillows. NanoSPACE mite-proof duvets and pillows contain Czech nanofabric that prevents the accumulation and multiplication of mites and their allergens inside the bedding. This significantly reduces the number of mites and prevents the formation of dangerous colonies that cause allergic reactions.

Another option is nanoSPACE Nanocotton® bedding. It's a very pleasant cotton satin with nanofiber fabric inside, which also prevents mites and allergens from penetrating. The bedding's advantage lies in its durable fabric structure with a fine glossy surface and colorfastness even after numerous washes.


What are dust mites, and how are they related to allergies?

Dust mites are tiny arachnids that often occur in households, especially in bedding, mattresses, carpets, and furniture. Allergies are triggered by mite excrement, which can cause symptoms like sneezing, itching, red eyes, stuffy nose, and more.

How can I reduce the number of dust mites in my home?

To reduce the number of dust mites, you can regularly vacuum, use mite-proof bedding and covers for allergy sufferers, maintain low humidity with the help of dehumidifiers and air purifiers for allergy sufferers.

How is dust mite allergy treated?

Treatment for dust mite allergy includes preventive measures, such as using pillows and duvets against dust mites. In more severe cases, antihistamines, corticosteroids, decongestants, and immunotherapy are prescribed. Always consult your doctor for the most suitable treatment for you.

What is immunotherapy, and how does it help with dust mite allergies?

Immunotherapy (also known as allergy vaccination) is a long-term treatment that helps reduce the immune system's sensitivity to allergens such as dust mites. Immunotherapy can be administered through injections or sublingual tablets. This treatment must be carried out under medical supervision and can last for several years.

Can dust mite allergies cause a rash?

Yes, dust mite allergies can cause a rash or eczema in some people. If you suspect dust mite allergy and a rash, consult your doctor to recommend appropriate treatment.

Do dust mites live in hair?

Dust mites typically do not live in hair, but they can be found on the scalp or in bedding. Dust mite allergies can cause itching of the scalp in some individuals.
