Fort Lauderdale, FL (AHN)- Immunology experts are beginning to agree that germs that many parents bleach and disinfect out of existence might help children. Studies show that exposure to germs help building child's immunity to the diseases caused by them.

"Hygiene hypothesis" holds that when babies are exposed to germs, it helps them fight allergies and asthma later.

According to the National Institute of Allergy and Infectious Diseases, and some experts believe that too much cleanliness might be a contributing factor for the ever increasing allergies past 15 years.

Dr. Dennis Ownby, chief of allergy and immunology at the Medical College of Georgia, found in a study that babies in households with multiple pets have fewer allergies at age 6 or 7 not just to animals, but also to ragweed, grass and dust mites. Adding to it he says that babies who have had allergies early in their life are found immune to them later.
