缺少睡眠让人发胖

熬夜不仅会给我们带来黑眼圈和坏脾气,一项最新的研究发现,熬夜还会让我们发胖。
A late night not only creates dark circles under the eyes and a grumpy temper - it can causeweight gain too, according to a new study.
在减少了男学生的睡眠时间之后,科学家们发现,睡眠不足会大大减缓新陈代谢的速度,而这会让类似呼吸、进食这样的简单活动消耗的热量也同时减少。
Scientists have discovered a lack of sleep can drastically slow the metabolism down which causes the body to use less energy for simple tasks like breathing and eating, after depriving male students of sleep.
这一发表在美国临床营养学杂志上的报告,再次证实了睡眠不足可能让人发胖。不仅是因为缺觉导致饥饿感大增,也是因为消耗热量的减少。  
The results,reported in the American Journal of Clinical Nutrition, add to evidence that sleep loss can promote weight gain - not just by boosting hunger but also by slowing the rate at which calories are burned. 
主导了这次研究的瑞典乌鲁萨拉大学的Christian Benedict认为,这项研究也认为足够的睡眠时间可能会避免发胖。
The study suggests that getting plenty of sleep might prevent weight gain, said Christian Benedict of Uppsala University in Sweden, who led the study. 
“我们的研究结果显示,彻夜不眠可以减少健康男性的热量消耗,这说明睡眠有助于控制人体在日间的热量消耗。”
'Our findings show that one night of sleep deprivation acutely reduces energy expenditure in healthy men, which suggests sleep contributes to the acute regulation of daytime energy expenditure in humans,' he wrote.    
之前也有不少研究发现每晚睡眠不足5小时的人群更可能发胖,罹患体重相关疾病,比如2型糖尿病的可能性也更高。
A number of studies have observed that people who sleep five hours or less are more prone to weight gain and weigh-related diseases such as type-2 diabetes.
不过之前的研究都不能证明睡眠不足是体重增加的原因。
But those studies do not prove that sleep loss causes weight gain.
专家认为生活方式以及饮食习惯可能会增加肥胖的可能性,但不能确定睡眠不足是否能导致肥胖。
Experts said that factors such as lifestyle and diet might add to obesity risks and that it was not clear that sleep deprivation led to obesity. 
波士顿医疗中心睡眠障碍中心的负责人Sanford Auerbach指出,睡眠不足是一个复杂的问题,药物以及其他因素都有可能影响睡眠,因此这一新发现不能推而广之。
Sanford Auerbach,head of the Sleep Disorders Center at Boston Medical Center, noted that sleep deprivation is a complex issue, with medication and other issues influencing sleep as well, and urged that the new findings be kept in context.
“这些研究显示人们会慢慢适应睡眠不足的情况,而这一适应的过程理论上可能导致肥胖。”他同时指出目前还不清楚长期睡眠不足会对荷尔蒙水平造成何种影响。     
'They showed that we adapt to sleep deprivation and that some of these adaptations could theoretically contribute to obesity,' he said, adding that it's not clear how chronic sleep loss influences hormone levels.      
美国国家睡眠基金会建议成年人每晚应有7到9小时的睡眠时间。
The National Sleep Foundation recommends that adults get about seven to nine hours of sleep each night.
