New research has shown that kids exposed to mouse, cockroach and cat allergens early in life, perhaps first three years exhibited diminished risk of asthma development that narrows and inflames the airways by the age of 7. Likely relationship was also found for dog allergens, as found by the scientists.

A professor at the University of Wisconsin-Madison, James E. Gem said their findings show that exposure to a wide range of indoor allergens, bacteria, and its products during the early stage of life cuts down the risk of developing asthma.

In a published work in the Journal of Allergy and Clinical Immunology, the researchers say microbial environment in the house during infancy can also lower the risk of asthma.

A study conducted earlier showed that exposing infants to some bacteria may prevent three-year-old kids from repeated wheezing, which a risk factor for developing asthma.

According to the researchers, there’s the need for more study to ascertain the possible functions of these microbial exposures in developing asthma.

The Director of the National Institute of Allergy and Infectious Diseases (NIAID) in Maryland, Anthony S. Fauci said they are studying more about the effect of kid’s environment on their health conditions. Fauci added that they could help prevent the troubles that come with asthma if they can find methods to prevent the occurrence of asthma.

The research team studied the risk factors for asthma among 442 kids in Urban regions, where the ailment prevails, and only 130 (29%) developed asthma about seven years of age.
