A recent study conducted by Dr. Robert Wood, of John Hopkins Children Center in Baltimore concluded that keeping a home too clean can potentially cause future allergy and asthma flare ups in children. The study was published on June 6th in the Journal of Allergy and Clinical Immunology. It specifically stated that in the first year of an infants life, it is important to expose the child to a certain level of germs and bacteria in order to develop their immune system and prevent asthma.

The study tracked 467 newborns in urban communities from womb to birth and years down the road. Results showed that 41% of the children, who were allergy free, were exposed to a significant amount of bacteria in their household.

Atlanta, Ga. (CBS Atlanta) – You may want to think twice before breaking out the ole’ duster.

In a recent study out of Johns Hopkins Children’s Center in Baltimore, keeping your home too clean may lead to asthma and allergy complications later in life for children.

In the study published June 6 in the Journal of Allergy and Clinical Immunology, researchers found that infants are far less likely to suffer from asthma or allergies later in life if they are exposed to household germs and bacteria as well as allergens from rodents, roaches, and cats in their first year of life,according to Healthy Day.

Dr. Robert Wood, co-author of the study and chief of the Division of Allergy and Immunology at the Johns Hopkins Children’s Center, looked at 467 newborns in inner-city communities across Baltimore, Boston, New York City, and St. Louis and tracked their health from the womb, to birth, and through the years.

Dr. Wood found that about 41 percent of children in the study without allergies grew up in households rich in allergens and bacteria.

However, the results from this study seem to contradict some prior research which reported that inner-city dwellers had higher levels of asthma after early exposure to rodent and animal droppings and allergens.

“What we found was somewhat surprising and somewhat contradictory to our original predictions,” said Dr. Wood, “It turned out to be completely opposite — the more of those three allergens you were exposed to, the less likely you were to go on to have wheezing or allergy.”

Despite this contradiction, the recent study does corroborate the “hygiene hypothesis,” which posits that children raised in overly clean households are more susceptible to developing allergies because their bodies do not develop the necessary responses to everyday allergens.

According to the Centers for Disease Control and Prevention, more than 14 percent of children have been diagnosed with asthma in the U.S, while another 11 percent suffer from respiratory allergies.

This study comes on the heels of experts saying that taking a shower everyday or taking long hot baths may not be as healthy for you as once believed.
