Is dust in homes a source of health risks?



  1. 0 Votes

    Research has clearly demonstrated that dust mite allergen increases the risk of various health effects. Nearly all of this research has been performed in houses. Where concentrations of mite allergen in house dust are greater than approximately 2 micrograms allergen per gram of dust, susceptible people have a much higher risk of becoming sensitized to (i.e., have an allergic response to) dust mite allergen. Those who are sensitized to dust mite allergen have a several-fold increased risk of asthma. Mite allergens exacerbate allergic rhinitis (inflammation of the nasal tissues due to allergen exposures causing sneezing, runny nose, postnasal drip, and congestion) and atopic dermatitis (allergen-caused inflammation of the skin resulting in rash and itching). A National Academy of Science committee concluded that the evidence was sufficient to conclude that dust mite allergen caused development of the disease of asthma and caused exacerbation of asthma in those with asthma.
