    Pet dogs 'may help children avoid asthma' 寵物狗“可能有助兒童避免患哮喘”

    文字稿

    瑞典的一項大型研究項目發現,家中有寵物狗的低齡孩子日后不大可能患哮喘。 BBC 記者 Michelle Roberts 有以下報道:

    Many people are allergic to dogs, or at least the dead skin cells and saliva that they shed as they groom themselves.

    But a new piece of research from Sweden suggests early exposure to these pets could cut a child's future risk of allergy. Living with a dog in the home in the first year of life was linked to a 13% lower risk of asthma in later childhood among the 650,000 children the authors tracked.

    The researchers say this fits with the hygiene hypothesis which favours exposure to dust and dirt to improve our tolerance of common allergens. But for a child who is already allergic to dogs, buying a puppy would not be a good idea.
