How to know if you have a dust allergy

Dust allergies are especially common in people who have a sensitivity to house dust mites. These tiny creatures live in many homes and can cause skin irritation and an allergic response in people with sensitive skin.¹  Dust mite allergies are caused by the body's reaction to dust mite secretions, which attach to the dust itself and spread easily throughout the home. These particles that cause symptoms cause the body to release histamines, which can lead to a number of symptoms, including hay fever, asthma, and eczema. ^{3, 2}

Dust mites are microscopic, arachnid-like creatures that can be found in almost all homes and areas where people live and spend time. ¹ They’re a quarter of a millimetre long and difficult to see with the naked eye. Specific proteins found in their bodies, secretions, and faeces can cause allergic reactions in those who are susceptible. Each mite produces about 20 of these secretions every day and the droppings continue to cause allergic symptoms even after the mite has died. ² House dust mites (Dermatophagoides pteronyssinus) are the most prevalent kind of dust mite in Australian homes. They prefers coastal regions over inland ones. ³ Human allergies to this mite have been linked to skin and respiratory conditions like eczema and asthma. ¹
