What is a Dust Allergy?

Dust AllergyAll homes in the UK have dust mites, but due to their tiny size (around 0.25-0.3mm) and translucent bodies they are almost invisible to the naked eye (don’t worry – unless you have a dust mite allergy, they are harmless).

A dust mite allergy is in fact a reaction to proteins in the excretion of the dust mites. Yes, that’s right, you’re allergic to dust mite poo.

When the allergenic proteins are breathed in or make contact with the skin of an allergic person, their body reacts with typical asthma and hay fever symptoms – wheezing, sneezing, runny nose and soreness and redness of the in the skin and eyes.

Dust mites thrive in warm humid environments, our beds being one of their favourite spots. We spend about a third of our day in bed, shedding skin cells and creating moisture with our breath and bodies which the microscopic mites need to live on.

Why do I react?

An allergic reaction is an overreaction of the body’s immune system to an otherwise harmless substance. The substance which triggers the reaction is called an ‘allergen’. This can be anything from pollen and dust, to foods or even latex.

The body reacts by producing excess histamines, which are part of an overreaction of the immune system.  This causes symptoms which can range from a rash or itching to difficulty breathing.

Symptoms

Spending more time inside during cooler months, (meaning increased contact with dust or pet allergens), can cause symptoms to flare up and become difficult to manage. This may actually be the first time someone realises that they have an allergy.

Indoor allergy symptoms caused by dust or pets can be very similar to the more well known hay fever symptoms.

Common symptoms include;

Allergen avoidance- practical tips for dodging allergy danger zones around the home.

    • Keep pets off sofas and beds (out of the bedroom altogether if possible).
    • Damp dust surfaces regularly.
    • Vacuum regularly. It may also be beneficial to install “Allergy Friendly” flooring. (Click here to see the Allergy UK range).
    • Use allergy friendly mattress covers and bedding. (Click here to see the Allergy UK range).
    • Keep cuddly toys and blankets in a cupboard to prevent the build up of allergens on them.
    • Don’t dry clothes inside over a radiator – this increases the humidity in your home and can result in mould, which releases tiny spores into the air that you breathe.
    • Mould and dust mites thrive in moist environments. Keep the humidity in your house between 40% and 20% to control allergens.
    • Be careful when using harsh chemicals for cleaning. The fumes can exacerbate breathing problems (a common trigger for asthma) and cause skin irritation.
