What causes Dust Mite Allergy?

Your immune system produces proteins that work as anti-bodies to eradicate unwanted bodies. In the process of fighting and taking our foreign objects infection occurs. 

Dust mite is like an allergen that affects the immune system and your body produces antibodies to fight it. This comes as a threat to your body even though it does not harm you in general. When you come in contact with a dust mite, immune response gets activated in your nasal passage and lungs. It happens in the nasal passage initially because that is the first place allergen travels to. Because of all this you start getting sneezes, cough, wheezing and other problems. 


Prolonged exposure to dust mites by a person who is allergic to it can result in asthma. Dust mites that enter your body live on skin cells that are dead. They absorb water from the atmosphere, so basically it does not do any harm to the body that could affect your health but it is like an autoimmune response in some people to fight against it. Another major cause of dust mite allergy is debris that is found in faeces and decaying bodies.
