研究:家中養寵物,小孩較不易過敏

  如果家裡有小孩是過敏兒的話,想必父母一定做好周全的保護措施,除了棉被、床單、窗簾等定期清潔外,也絕不讓孩子接觸到貓狗,更別說是養寵物了!不過在2011年7月有篇刊於美國臨床免疫及過敏醫學期刊(Journal of Allergy and Clinical Immunology)的研究,可是會大大顛覆這個觀念喔!

  該篇研究由澳洲墨爾本大學(University of Melbourne)發表。研究人員分析一份跨越22個國家、人數為8,486人的長期大型研究後發現,研究對象中,約有1/4人有潛在過敏性疾病,且大部分的人都是在青春期時才慢慢顯現出來;但是假如在小時候與越多玩伴或是兄弟姐妹相處的小孩,長大後鼻子過敏(nasal allergy)的機率就會越低;除此之外,更發現小孩在五歲前,如果生長在有農場的環境或是家中有養寵物的話,比起皆無這兩種經驗的孩子,鼻過敏的機率下降了30%。而鼻過敏常是引發小孩氣喘或其他過敏性疾病的元兇,所以不得不注意它的嚴重性。

  率領研究的Melanie Matheson博士也表示,研究結果並不是要父母們立刻開始養寵物或是計畫生多一點的孩子,重要的是,不要怕會引起孩子過敏而限制他們接觸寵物或是草地等,反而應多讓他們在小時候多親近大自然、多與玩伴相處。有助於提升自我保護的免疫力!

    事實上, 從小多親近大自然, 也可以改善或避免形成過敏體質的~
