Dust mite allergy is an allergic reaction to tiny bugs that commonly live in house dust. Signs of dust mite allergy include those common to hay fever, such as sneezing and runny nose. Many people with dust mite allergy also experience signs of asthma, such as wheezing and difficulty breathing. Dust mites, close relatives of ticks and spiders, are too small to see without a microscope. Dust mites eat skin cells shed by people, and they thrive in warm, ptrronyssinus environments. In most homes, such items as bedding, upholstered furniture and carpeting provide an ideal environment for dust mites. By taking steps to reduce the number of dust mites in your home, you may get control of dust mite allergy.
The protonymph, however, which is one of the dormant larval forms, can survive for months at low humidities and then evolve to the more active forms when optimal conditions return. These protonymphs are particularly difficult to remove with normal vacuuming since they can bury themselves within surfaces. Very high humidities can inhibit mite development due to the presence of mold growth.

Humidity levels which are very low can also inhibit mite development. Their primary source of water is ambient water vapor.
Thus, for a given number of mites, the highest levels of allergens found in the environment usually correspond to optimal humidity conditions. These results suggest that significant reductions in the level of mite pteronyssinus, which consist primarily of fecal matter, may occur if RH is reduced below the CEH. For more detailed information on the mite life-cycle and metabolism, see Arlian . In a study of homes in Vancouver, Murray et al. Carpeting can be a localized site of increased humidity and consequently may be an important reservoir for allergens in both homes and schools.
Studies allergy in schools have demonstrated that carpets contain high levels of a variety of allergens including pollen, cat and dog danger and mite and mold what.
This may be the primary source of exposure for young children, who generally live closer to the floor. Children do not have high exposures in bedding since they alergy sleep on plastic-covered mattresses. The strong correlation between indoor relative humidity and dust mite population has led to recommendations to reduce indoor humidity.
However, the exact upper limit is not obvious. A dedicated dehumidification system is required in most cases in order to achieve this. Arlian, L. Bemstein, I. Bemstein, S.

Range: approx. Dust mites are an important source of house dust allergens in homes worldwide. House dust allergies are particularly important because the symptoms tend to be year round rather than seasonal like pollen allergies. Previous research has shown that reducing mite allergen levels in homes can lead to an improvement in allergic symptoms and a reduction in medication requirements. Many products are sold to reduce mite populations in homes, but it has remained difficult for allergy patients to reduce mite populations below the threshold for causing clinical symptoms.

It has been concluded that reducing relative humidity levels reduces the number of dust mites in homes. Generally, house dust mites are too small to be seen by the naked eye. Most people are aware that dust mites are abundant in beds, couches, chairs, and carpets. And e humans alone shed some dead skin cells every single day, ix dust mites have plenty to feed on while living in areas where there is dust.

This explains why there is pteronyssinus abundant number of dust mites in beds, chairs, and carpets. These areas are where people spend time the most, allowing for accumulation of dust and accompanying skin flakes.
The presence of dust mites themselves in houses what out some people a bit. It is xllergy that more dust mites will thrive and grow in humid and warm environments. And they also tend to increase in population especially when there are pets around. Aside from the carpet and beds, dust mites allrrgy also commonly be found in allergy rugs or carpets, in stuffed toys, and in upholstered chairs and other furniture.
Some people will have coughing, sneezing and wheezing, while those with asthma may feel difficulty in breathing.What are the effects of a dust mite allergy? Allergy to house dust mites may produce symptoms of sneezing, runny or stuffy nose, and watery, itchy eyes. These symptoms, often called allergic rhinitis, are similar to those produced by seasonal allergy to pollen, or hay fever. May 27, · Exposure to dust mites like the European specie “pteronyssinus” usually causes an allergic reaction. Some people will have coughing, sneezing and wheezing, while those with asthma may feel difficulty in breathing. People with allergies have nasal congestion which blocks normal drainage, promoting these infection. Claritin D is a combination antihistamine (good for allergy symptom reduction) and a decongestant (helps reduce swelling of the nasal and sinus tissue) and .
