    Asthma and allergies: does a too clean house increase the risk?

    It is right to live cleanly, but even in this case we must not exaggerate. A home that is too clean can increase the risk of asthma and allergy in children, with possible complications as adults, according to a recent study, conducted at the Johns Hopkins Children's Center in Baltimore.

    It is right to live cleanly, but even in this case we must not exaggerate. According to a recent study conducted at the Johns Hopkins Children's Center in Baltimore, a house too clean can increase the risk of asthma and allergy in children, with possible complications as adults.

    The study in question was published on June 6 in the scientific journal Journal of Allergy and Clinical Immunology. The researchers highlighted that babies and children will have a lower risk of suffering from asthma and allergy if they are exposed, particularly in their first year of life, to germs and bacteria normally present in the home, as well as to allergens originating from cats, rodents and cockroaches.

    Dr. Robert Wood, co-author of the study and director of the John Hopkins Center's Division of Allergy, examined 467 infants in Baltimore, Boston, New York City, and St. Louis and considered their health from the womb. , at birth and over the years.

    The study found that approx 41% of allergy-free children grew up in homes rich in allergens and bacteria. The expert opinion, the results obtained turned out to be surprising and sometimes contradictory with respect to what was previously reported and compared to the original forecasts.

    This study marks a point in favor of "Hygienic hypothesis", according to which children raised in too many clean houses are more prone to suffer from allergies, as their bodies do not develop the necessary responses to deal with the most common allergens they deal with every day.

    In the United States, 14% of children have been diagnosed with asthma, while 11% suffer from respiratory allergies, according to data collected by the Centers for Disease Control and Prevention. Perhaps, leave children more free to play with pets, in the open air and in rooms of the house where some dust has accidentally remained could guarantee them better health as adults.
