Have you ever wondered why you are hungrier than usual if you do not get a good night's sleep? Researchers from the University of Chicago say they have found one reason. Their study reveals that a lack of sleep makes people hungrier the following day. Sleeplessness releases chemicals in the brain that enhance the pleasure derived from eating, which also makes us eat more. We want to eat food that is high in calories. The researchers found that sleep-deprived people craved crisps, sweets and biscuits far more than healthier foods. The researchers also reported that people in the study who did not get enough sleep ate up to twice as much fat content as when they had slept for eight hours.

為什么晚上睡不好會感到比平時俄？芝加哥大學的研究人員找到了原因。研究表明晚上缺覺第二天會更餓。當人們睡眠不足時，大腦會釋放一種能夠提高興奮的化學物質(zhì)，并引發(fā)食欲。導致我們食用了大量高卡路里食物。研究人員發(fā)現(xiàn)，比起健康食物，缺覺一族狂人薯片、甜食以及餅干。研究人員還表示，比起睡足八小時人群，缺覺一族的脂肪攝入量是前者的兩倍之多。

The study was conducted on 14 male and female volunteers in their twenties. They were observed by researchers in two different situations. In one, they spent 8.5 hours in bed each night and averaged 7.5 hours of sleep. In the other, they spent just 4.5 hours in bed and averaged 4.2 hours of sleep. The researchers noted that in the first situation, the subjects ate three meals a day, as normal. However, in the second situation, where they had been deprived of sleep, the volunteers were unable to resist what the researchers called "highly palatable, rewarding snacks". This happened just 90 minutes after they had eaten a meal that supplied them with 90 per cent of their required daily calories.

男女志愿者總共14人，年齡均在二十幾歲。并分別從兩種情況進行研究。第一組，志愿者臥床時間8.5小時，平均睡眠時間7.5小時。第二組，臥床時間4.5小時，平均睡眠4.2小時。在第一組中，研究人員注意到志愿者每日照常食用三餐。但在第二組中，缺覺一組無法抵御美味小吃的誘惑。食用時間僅僅距離上次用餐90分鐘，而90分鐘前的用餐已經(jīng)提供了每日卡路里需求量的90%。
