Napping for more than an hour in the daytime may raise the risk of Type 2 diabetes by 45 per cent, a new study shows. Researchers at the University of Tokyo used data from 21 studies involving more than 300,000 people who had recorded their daily level of napping.
一項新的研究顯示，白天午睡時間超過1小時，可能會讓罹患第2型糖尿病的風險增加45％。日本東京大學研究人員使用來自21份研究的資料，涵蓋超過30萬人的每日午睡時間紀錄。
Their research found there was a link between long naps and a higher risk of diabetes. However there was no risk before one hour. The researchers said long naps could be a result of disturbed sleep at night, potentially caused by sleep apnoea.
他們的研究發現，長時間午睡與罹患糖尿病的較高風險有關。不過，午睡時間在1小時內沒有患病風險。研究人員指出，長時間午睡可能是夜晚睡眠不安穩所導致，成因可能是睡眠呼吸中斷。
This sleeping disorder could increase the risk of heart attacks, stroke, cardiovascular problems and other metabolic disorders, including type-2 diabetes. Sleep deprivation, caused by work or social life patterns, could also lead to increased appetite, which could increase the risk of type-2 diabetes.
這種睡眠障礙可能增加心臟病、中風、心血管問題，以及其他新陳代謝失調的風險，包括第2型糖尿病。由於工作或社會生活模式引起的睡眠剝奪，可能也會導致胃口大增，提高罹患第2型糖尿病的風險。
"Several studies have demonstrated beneficial effects of taking short naps less than 30 minutes in duration, which help to increase alertness and motor skills while a long nap might increase the risk of diabetes." said lead autor Dr Yamada Tomahide.
研究主筆山田知秀博士指出：「數項研究顯示，午睡期間少於30分鐘，有助於提升警覺性和駕駛能力，但長時間午睡可能增加罹患糖尿病的風險。」
