Dust Mite Control Studies
Doctors have clearly stated that once the source allergens are removed or drastically reduced there will be a noticeable improvement in overall health.
Studies have shown that environmental control is a key element to the management and treatment of asthma, eczema, rhinitis and allergies in general. See below for some examples of medical journals which express the importance of house dust mite allergen avoidance and environmental control measures.
"Mite-impermeable encasings are effective in reducing the number of mite-sensitized children with asthma attending the hospital with asthma exacerbations but not the number requiring oral prednisolone. This simple measure may reduce the health care burden of asthma exacerbations in children"

"Encasing of mattresses and pillows resulted in a significant long-term reduction in allergen concentrations in mattresses and in the need for inhaled steroids in children with asthma and House dust mite allergy."

"Mite population and allergen levels decreased by 90% or more within a month of placing mattress and pillow covers and treating bedding."

"Tests completed on people with atopic dermatitis (eczema) demonstrate that the reduction of mite allergens improved the condition, greatly reducing the activity of atopic dermatitis in some people. There is a need to identify the people who will gain from this intervention." P.S. Friedmann, The Lancet, 347, Jan.6 1996
"In addition to genetic factors, exposure in early childhood to house-dust mite allergens is an important determinant of the subsequent development of asthma."

"Dust mites produce an allergen that disrupts the skin's ability to act as a barrier to other allergens and environmental irritants according to research published in the Journal of Investigative Dermatology."
Toshiro Takai and colleagues convincingly demonstrate evidence of such disruption. Their finding indicates that the inflammation, increased allergen susceptibility, itchiness and dry skin are first triggered by the protein-degrading action of the dust-mite allergen. Since dust mites inhabit even the cleanest homes and live in furniture, carpets, and bedding - it is their dead skin and droppings that cause allergic reactions - many have the potential of a reaction.
