Could House Dust Mites Be Affecting Your Family’s Health?
By Lorelei Berriman — Integrative Health Nurse
Living in a Dust Mite Hotspot
Living in the Northern Rivers is a blessing — lush rainforests, ocean breezes, and vibrant community life. But our warm, humid climate also creates the perfect environment for house dust mites. Invisible to the eye, these tiny creatures may be quietly affecting your family’s health, especially the wellbeing of children.
Dust mites live in bedding, carpets, and soft furnishings. It isn’t the mites themselves that cause problems, but the proteins in their droppings and body parts. These particles are released into the air when we move on the bed, vacuum, or sit on the couch. For people who are sensitive, exposure can lead to blocked noses, sneezing, itchy eyes, asthma flare-ups, or even eczema. Children are particularly vulnerable as they spend more time in bed and breathe more rapidly, increasing their overnight exposure.
Local Research Confirms the Risk
Here in our region, research has confirmed just how significant this problem is. A landmark study comparing Lismore’s humid coastal climate with drier inland towns found eight times higher levels of dust mite allergen in Lismore homes. Children allergic to dust mites on the coast were far more likely to develop asthma and breathing issues. Even the ABC once reported that “dust mites love Lismore conditions,” a reminder that this challenge is woven into our local environment.
Dust Mites as a Driver of Other Allergies
Dust mite allergy doesn’t always stop with a runny nose. It can act as a driver of other sensitivities, adding to what specialists call the allergic load. When the immune system is already working hard to defend against dust mite proteins, it can become more reactive to other allergens like pollen, mould, and pet dander. This is why some families notice that hay fever, eczema, or asthma worsens in dusty or humid conditions.
There is also the issue of cross-reactivity. Some of the proteins found in dust mites — particularly tropomyosin — are very similar to proteins found in other species, such as cockroaches, shellfish, and even certain parasites. Because the immune system often can’t tell the difference, someone sensitised to dust mites may also react to prawns or crabs without having eaten them before, or show positive allergy tests to multiple triggers at once.
This overlap helps explain why dust mite allergy is seen as a “driving allergy”: it can prime the immune system, heighten responses to unrelated allergens, and in children contribute to the atopic march — the common progression from eczema in early years to hay fever and eventually asthma.
A Collaborative, Integrative Approach
At The Health Lodge, we see dust mite allergy as part of the bigger picture. Our allergy clinic provides testing to identify whether dust mites are a factor, and we offer oral desensitisation (sublingual immunotherapy) — gentle daily drops or tablets under the tongue that retrain the immune system to become less reactive. This treatment has been shown to reduce symptoms, lower medication needs, and improve quality of life.
Our strength lies in our collaborative approach. Alongside integrative GPs, our team of nutritionists, naturopaths, and health specialists work together to create a multi-layered plan. This may include addressing environmental exposures, supporting diet and nutrition to reduce inflammation, restoring gut health as the foundation for balanced immunity, and providing targeted immune support. We also offer Functional Breathwork Analysis, helping children and adults with asthma, sinus issues, or anxiety to develop healthier breathing patterns that support both lung and nervous system health.
This work builds on the foundation laid by pioneers in the field — Dr Karel Hromek, Dr Merve Garrett, and Dr Ann Mary Amber — who have dedicated more than 30 years to advancing allergy care in Australia. At The Health Lodge, we are proud to continue their legacy, blending decades of knowledge with modern integrative care to support families in our community.
Take the Next Step
If you or your children experience ongoing allergy, asthma, or eczema symptoms, dust mites may be part of the story. With the right assessment and a whole-person approach, relief is possible.
