Swedish scientists have found that children living in families with pets (cats and dogs) are less likely to be allergic to dust and pollen. The larger the number of pets, the better.
The study took into account the number of animals living at home during the first year of a child 's life, as well as those suffering from allergies and d? asthma among family members.
Children suffered from 48 to 49% of allergies in homes other than pets, while children were allergic to 35-43% in single-animal homes. Five animals were perfectly healthy.
Scientists say that any early contact with animals can be beneficial to the immune system and resist allergens.
"Many studies have shown that children's exposure to allergies and early stage microbes plays an important role in developing protection against asthma and allergic diseases," said one researcher from Purdue University in Indiana.
