The mite allergy is a type of hypersensitive reaction to proteins in the emission of dust mites. These proteins attack the respiratory passages developing the hay fevers and asthma conditions.

It also triggers the atopic dermatitis especially in the people who have tendency to this problem. Dust mites are generally found in all homes, they are microscopic organisms that flourish in the warm and humid ambience with lots of food and human skin.

Usually the mites live in the beds and easily enter our bodies through inhalation. When these mites are inhaled or touched to the skin, the body generates the antibodies which effects the discharge of chemicals known as histamines that results in swelling and irritations to the upper respiratory passages especially developing the asthma and hay fever like symptoms. However, the tendency for alergy is frequently inherited.
