研究：睡眠不足導致基因無力 Lack of sleep leads to groggy genes： study

Lack of sleep has a potentially harmful effect on gene expression, according to a study out Tuesday that sheds light on the link between sleep deficits and a wide range of health conditions. 週二公布的一份研究說明睡眠不足與多項疾病的關聯性，根據研究，睡眠短缺可能有害基因表現。 Lack of adequate shut-eye had already been linked to conditions from heart disease and cognitive impairment to obesity. But sleep researcher Derk-Jan Dijk and his fellow researchers have delved into the molecular mechanisms behind the phenomenon, looking at how missed sleep leads to health problems. 缺乏足夠的闔眼已被與多項疾病連結，從心臟病、認知障礙到過胖等。但睡眠研究人員狄克與研究員同僚更深入這種現象背後的分子機制，研究睡眠不足如何導致健康問題。 They found that a week of sleeping six hours or less a night affects the expression of some 711 genes -- including those involved in inflammation, immunity, and stress responses. 他們發現，一週內每天睡眠不超過6小時，影響約711種基因表現，包括與發炎、免疫、壓力反應等有關的基因。 Moreover, compared with test subjects who were allowed to sleep as long as 10 hours a night, those who lacked sleep had irregularities in their genes’ circadian rhythms. （AFP） 此外，相較於一晚得以睡長達10小時的受試者，缺乏睡眠者的基因生理時鐘紊亂。（法新社） 新聞辭典 groggy：形容詞，無力的。例句：I felt a bit groggy for a couple of days after the operation.（我手術後好幾天感到沒力。） shed light on：片語，闡釋。例句：As an economist, he was able to shed some light on the problem.（身為經濟學家，他對這個問題能提供些許看法。） delve into：片語，探究某事。例句：It’s not always a good idea to delve too deeply into someone’s past.（太深入探究別人的過去不是件好事。）
