Causes of dust mite allergy

Dust mites basically consume skin cells that people shed. Instead of drinking water, they absorb water from the humidity present in the atmosphere. They thrive best in temperatures that range from 18.5 – 29 C.

Since house dust is easily embedded in the fibers of carpeting, bed linens and furniture cushions as well as holding moisture. This is the reason why bedrooms are the best habitats for dust mites.

Even dust that contains the decaying bodies of dust mites and their feces can also trigger the allergy.

Treating dust mite allergies

The initial treatment for controlling dust mite allergy is to avoid them as much as possible. Once the exposure to dust mites is minimized, expect fewer reactions that are no longer severe. Nevertheless, it is impossible to completely get rid of dust mites.

Allergy medication can be prescribed by your doctor in order to improve the nasal symptoms. It includes antihistamines, corticosteroids, decongestants, cromolyn sodium, and leukotriene modifiers. Other therapies that can be used include immunotherapy and nasal irrigation.

Home remedies for dust mite allergy

The best strategy is to avoid dust mite exposure in order to control the allergy. Even though dust mites cannot be completely eliminated, there are ways to control their numbers.

  • Use bed covers that are allergen-proof. These covers are usually made out of tightly woven fabric that prevents mites from inhabiting them.
  • Beddings should be washed every week. Sheets, pillowcases, blankets and bedcovers should be washed in hot water to eliminate dust mites.
  • Humidity level must be low by setting the dehumidifier or air conditioner at low humidity.
  • Select beddings carefully by avoiding those that trap dust and difficult to clean.
  • Utilize an efficient filter in your air conditioning unit or furnace. Just make sure that it should be changed every three months.
