Causes Of House Dust Mite Allergy

The excretion of mites contain several proteins. When they are inhaled or touch the skin, the body produces antibodies. These antibodies trigger the release of a chemical called histamine, which leads to swelling and irritation of upper respiratory tract - usually symptoms of fever and hay asthma. Predisposition to allergy is often hereditary.

Unlike pollen, dust mites are present all year round causing constant allergy - allergic rhinitis 'perennial'. Secretion mites dries out and can be launched into the air when someone enters into a mat, sitting on a chair, or shakes the bed linen, people in immediate allergic symptoms.
