    產婦體態走樣 睡得少是主因

    【台灣醒報記者張瑋報導】產後身材走樣,原來不是吃多了,真正原因是睡少了。美國醫學一項最新研究發現,女性產後難以恢復身材,可能與她們睡眠不足有關。專家研究產後6個月的女性,睡眠5小時或更少者,減重比睡眠7小時以上的女性困難兩倍,因為缺乏睡眠會影響到荷爾蒙的分泌。
     

    美國健康生活新聞網報導,流行病學專家埃麗卡•岡德森由940名來自麻州的產婦研究發現,產後6個月的婦女,睡眠時間少於5小時與睡眠多於7小時的婦女相比,前者無法恢復懷孕前身材的機率,比後者高出兩倍。

    岡德森說,睡眠時間不足是導致女性產後難以恢復身材的因素之一。芝加哥大學醫學中心研究人員西麗蒙烏特拉庫爾說明原因是,「缺乏睡眠會改變影響荷爾蒙分泌」。

    研究者表示,人體由腦下垂體前葉所分泌的生長荷爾蒙,是依照生理時鐘變化來進行,以晚上分泌最多,在晚上11時到凌晨1時之間最旺,功能是促進體內器官的發育成長,加速體內脂肪的燃燒,與胰島素相抗拮,防止體內脂肪堆積。

    但晚睡的人,就會造成這種荷爾蒙分泌失調,分泌不活躍,加上攝取的熱量若超出身體所消耗的熱量,多出的營養素日積月累,就會形成脂肪,體態自然就會越來越臃腫。
