The dust mite is most common cause of allergic rhinitis and asthma. A dust mite is a microscopic, eight-legged insect. More than 100,000 dust mites can be in a single gram of dust. People are not allergic to the dust mite itself, but to dust mite feces. Dust mites eat the microscopic skin dander found on people and animals, then leave droppings. Each dust mite can produce approximately 20 droppings each day. Dust mites are found on people, animals and on almost every surface in homes, including carpet, upholstered furniture, mattresses and box springs, sheets and blankets, pillows and stuffed animals. When dead dust mites and dust mite droppings become airborne and are inhaled, they may produce an allergic reaction.
Wherever the relative humidity is greater than 50 percent for some time of the year, dust mites thrive. Dust mite females can lay 25-50 eggs during its lifetime of two to three months. They make their nests in dark, warm, humid environments, which makes beds and bed covers the ideal host. A dust mite's favorite food is shed scales from human skin. A single bed can have more than one million dust mites.
An allergic person's system produces an allergy antibody (IgE) in response to dust mite allergens. For an allergic individual, an allergy antibody is a fuse that ignites an "allergy bomb"--cells that release histamine and other natural chemicals triggering allergic symptoms. Histamine can be released anywhere in the allergy-prone victim's body. Symptoms of allergic rhinitis (an allergic reaction of the nose and sinuses causing swelling and inflammation) include sneezing, runny nose, itchy and watery eyes, cough and sinus headaches. Symptoms of asthma (an allergic reaction in the lungs) include difficulty breathing, wheezing and coughing.
