Do you know there are tiny bugs belonging to spider family that lives in dust in our houses and feeds on dead skin cells regularly shed by the human? These tiny bugs thrive in warm and humid environments and triggers asthma and allergy.

These tiny creatures do not bite but produce allergens. When we breathe the waste product released by the dust mites, our Immune System gets kicked and produces antibody response against them. The reaction may cause asthma and sinus infections.

Dust mite allergy affects about 20 million people in the United States. Long-term exposure to Dust mite leads to asthma and sinus infection.

Dust mites are almost present in every home, and it is nearly impossible to get rid of these tiny creatures. However, there are ways to lessen Dust mite allergy that we will discuss in this article.
