《中英對照讀新聞》Sleeping with light on may lead to weight gain︰study 研究：開燈睡覺可能會變胖
◎國際新聞中心

Too much light at night appears to lead to weight gain. The researchers found that mice exposed to a dim light at night over eight weeks had a weight gain that was about 50 percent more than other mice that lived in a standard light-dark cycle.

晚上照太多燈光似乎會導致體重增加，研究人員發現，老鼠晚上暴露在微弱燈光下8週，比生活在正常日夜週期的老鼠體重增加約50%。

"Although there were no differences in activity levels or daily consumption of food, the mice that lived with light at night were getting fatter than the others," said Laura Fonken, lead author of the study and a researcher at Ohio State University.

俄亥俄州立大學的研究人員、此份研究的主要執筆人方肯表示：「雖然活動程度或是每天食物攝取量沒有不同，但生活在夜間開燈環境下的老鼠，比其他老鼠胖。」

The study, which appears in the Proceedings of the National Academy of Sciences journal, said the weight gain could be a sign that light has an effect on the metabolism.

這份刊登在美國國家科學院院刊的研究表示，體重增加也許是光線會影響新陳代謝的一個跡象。

If these results are confirmed in humans, it would suggest that late-night eating might be a particular risk factor for obesity, Nelson said.

尼爾森說，這些結果如經人體證實，可能顯示深夜進食或許是過胖的特定風險因素。
