In fact, allergy and asthma sufferers may experience even worse symptoms indoors. As a result, the EPA has identified indoor air pollution as one of the five most urgent environmental risks to public health. Fortunately, there are many simple steps that can reduce exposure to pollutants triggering asthma and allergy symptoms at home. If you must keep pets, bathe and groom them often and minimize their access to carpeted areas and bedrooms of anyone in the house with allergies and asthma.
