House dust mites are found in all homes. They are microscopic organisms that thrive in warm and humid houses with lots of food which is the human skin. The mites prefer to live in beds and, because we spend about a third of the day in bed and we inhale large quantities of dust mite allergens. Unlike pollen, they are present all year round causing constant allergy ‘perennial’ allergic rhinitis. House mite allergy is a hypersensitive reaction to proteins in the excretion of dust mites. The protein attacks the respiratory passages causing hay fever and asthma. People who have a tendency of having atopic dermatitis will aggravate. The excretion of the mites contains a number of protein substances when inhaled or touch the skin, the body produces antibodies. These antibodies cause the release of chemical called histamine that leads to swelling and irritation of the upper respiratory passages typical asthma and hay fever symptoms. The allergy is often hereditary.
