Tips for house dust allergy: How probiotics can help

Hausstauballergie und Probiotika

House dust allergy is one of the most common allergies worldwide and affects millions of people. The typical symptoms such as sneezing, stuffy nose, itchy eyes and skin rashes can have a major impact on daily life. Many sufferers turn to medication to relieve their symptoms, but there are also natural approaches that can help. Probiotics have become increasingly important in the treatment of allergies, including house dust allergies, in recent years. In this article, we give you practical tips for reducing allergens in your home and show how probiotics can play a role in relieving symptoms.

What is a house dust allergy?

A house dust allergy is an overreaction of the immune system to house dust mites , tiny arachnids that feed on human skin flakes and live in mattresses, carpets, upholstered furniture and bedding. The actual triggers of the allergy are the proteins in the excrement of these mites.

The most common symptoms are:

  • sneezing and runny nose
  • Stuffy or itchy nose
  • Itchy eyes or skin irritation
  • Cough and in severe cases asthma

Tips for reducing dust mite allergens

1. Regular vacuuming and mopping

House dust mites love dusty environments. To reduce the burden:

  • Use a vacuum cleaner with a HEPA filter to capture the finest particles.
  • Wipe smooth surfaces regularly with a damp cloth to pick up dust rather than stirring it up.
  • Avoid carpets and hard-to-clean upholstered furniture where mites can accumulate.

2. Bed linen and mattress care

Since dust mites prefer to live in bed linen and mattresses:

  • Wash bed linen, pillowcases and blankets at least once a week at 60 degrees Celsius to kill mites.
  • Use dust mite-proof covers for mattresses and pillows.
  • Replace mattresses every eight years and ventilate the bedroom regularly.

3. Improve indoor climate

Mites thrive in humid environments. To improve the indoor climate:

  • Keep the humidity below 50% . A dehumidifier can be helpful here.
  • Ventilate your home regularly to reduce humidity.
  • Avoid houseplants in the bedroom as they can increase humidity.

The Role of Probiotics in House Dust Allergy

Probiotics, often referred to as "good bacteria," are microorganisms that promote the balance of gut flora. In recent years, research has shown that probiotics play a much larger role than just supporting gut health. They have the potential to regulate the immune system and may help with allergies, including dust mite allergy.

How Probiotics Affect the Immune System

The immune system of allergy sufferers overreacts to harmless substances such as dust mites. Probiotics can:

  • Modulate the immune system: They promote the production of regulatory T cells that dampen pro-inflammatory immune reactions.
  • Reduce inflammation: Certain strains of probiotics can reduce histamine production , which is responsible for allergic symptoms.
  • Strengthen the barrier function of the mucous membranes: A healthy intestine is an important barrier against allergens that could irritate the immune system.

Which probiotics are particularly effective?

Not all probiotics are the same. Certain strains have been shown to be particularly effective in allergy prevention and treatment:

  • Lactobacillus rhamnosus GG: Supports the immune system and helps alleviate allergic reactions.
  • Bifidobacterium lactis : Promotes the production of protective immune cells.
  • Lactobacillus acidophilus : Helps reduce inflammation in the respiratory tract.
  • Lactobacillus paracasei : The best studies are probably for Lactobacillus paracasei for house dust allergy. Lactobacillus paracasei LP-33 and GMNL-133 in particular have been shown in many studies to effectively alleviate the symptoms of allergies and can be very helpful, especially for house dust allergy.

How to integrate probiotics into your daily routine

dietary supplements

Probiotics are widely available in capsule form and offer an easy way to get the strains you need in sufficient quantities. Make sure to choose a product with sufficient live cultures (at least 1 billion CFU per dose). You should especially look for probiotics that have also been clinically tested for house dust allergy.

Probiotic foods

In addition to dietary supplements, you can also get probiotics through food. Particularly rich in probiotics are:

  • yogurt (with live cultures)
  • kefir
  • sauerkraut (uncooked)
  • kimchi
  • miso

Long-term use

Probiotics do not work overnight. To see noticeable improvements, you should take them over several weeks or months. Regular intake of probiotics can strengthen the immune system in the long term and reduce the frequency and severity of allergy symptoms.

Conclusion: Natural support for house dust allergy

Combining hygienic measures to reduce dust mite exposure and taking probiotics can be an effective strategy for relieving dust mite allergies. Probiotics offer a natural way to boost the immune system and mitigate allergic reactions without relying on medication. If you choose to take probiotics, make sure to choose high-quality products with the right strains and consistently incorporate them into your daily routine.
