Study Reveals How Dust Affects Asthma

Researchers at the National Institute of Health (NIH) revealed why dust exacerbates asthma so severely: bacterial protein. Doctors and asthma sufferers have long recognized the effect dust has on asthma symptoms, but it has never been scientifically clear as to why the effect is so acute. The study by the NIH and Duke University identified a bacterial protein as the culprit worsening the allergic reaction. Such a component had long been suspected, but the presence of a protein flagellin in house dust has since been documented.

The research, which studied both humans and mice, was published by Duke University Medical Center and the National Institute of Environmental Health Sciences (NIEHS). The article discusses how protein flagellin is not itself an allergen but is able to boost allergic responses in scenarios where allergens are present. The study also showed that there is a gene in people and mice that allows for the detection of the flagellin. After inhaling common house dust, the mice who had the appropriate gene responded to the presence of the flagellin with mucus production and obstruction and inflammation of the airways. The mice that did not have the gene did not respond to the flagellin and responded to the dust in a much milder manner.

In the human portion of the study, scientists were able to show that people with asthma had higher levels of antibodies to fight flagellin than non-asthmatics did. This data suggests that common house dust is a major component in the development of asthma, and many asthma sufferers can significantly reduce their symptoms, or even possibly eliminate them, by following a thorough cleaning regimen.

To combat dust, people should ensure that their home is well sealed but also well ventilated, and they should use a portable HEPA air purifier. Additionally, it is important to dust on a daily basis and perform an extensive dusting once every week. The best way to dust is to use a slightly damp cloth or microfiber cloth and then vacuum immediately afterward. The vacuum should be a model that uses a HEPA filter.

The benefit of a HEPA filter is that it removes 99.97 percent of all airborne particles down to 0.3 microns in size, which includes virtually all dust particles. Along with regular cleaning, HEPA filtration is the best way to combat dust. For this reason, many allergy and asthma sufferers depend on HEPA air filters to ensure easy breathing and optimal indoor air quality.  A top quality HEPA air purifier can effectively remove the airborne contaminants you and your family breathe. Ensure that the air in your home is as clean as it can be: Buy a HEPA air purifier from Clean Air Plus today.
