Childhood Exposure To Pets Reduces Asthma Risk

Household exposure to pets during the first three years of life appears to reduce your risk of developing asthma later on.
Published in the Journal of Allergy and Clinical Immunology study found out that exposure to cat, mouse, and cockroach allergens before the age of 3 reduces the risk of getting asthma by age 7.The researchers also found a link between bacteria and asthma development – certain bacteria influenced development, although further research is needed to know more.
“If we can develop strategies to prevent asthma before it develops, we will help alleviate the burden this disease places on millions of people, as well as on their families and communities,” said Anthony Fauci, Director of NIAID 
This study assessed 442 children, 130 of whom had asthma. They sampled dust from their homes when they were aged 3 months, 2 years, and 3 years. They found that when there were higher levels of mouse, cat, and cockroach allergens, children were significantly less likely to have asthma at the age of 7.
“Our observations imply that exposure to a broad variety of indoor allergens, bacteria and bacterial products early in life may reduce the risk of developing asthma,” explained Professor James Gern, one of the study’s authors. “Additional research may help us identify specific targets for asthma prevention strategies.”
