You can put gaining extra inches on your waistline to the list of health issues related to a lack of shut-eye – a list that already includes faster cell ageing, neuron damage, and reduced memory capability.
睡眠不足會帶來一系列的健康問題，其中包括細胞迅速衰老、神經(jīng)元損傷以及記憶力減退，還會導致你的腰圍增加。

That's the conclusion of new research that found adults sleeping for six hours a night had average waist measurements 3 centimetres (1.2 inches) larger than those sleeping for nine hours a night.
一項新研究發(fā)現(xiàn)，每晚睡6小時的成年人的腰圍平均比每晚睡9小時的成年人的要粗3厘米（1.2英寸）。

"Our findings support the accumulating evidence showing an important contribution of short sleep to metabolic diseases such as obesity," report the researchers.
研究人員表示，“越來越多的證據(jù)表明，睡眠不足會引起新陳代謝疾病，例如肥胖，我們的研究成果支持了這一觀點?！?/div>

The data also showed a link between shorter sleep times and reduced levels of HDL cholesterol, the 'good' type of cholesterol responsible for removing harmful cholesterol from the bloodstream and reducing the risk of heart disease.
數(shù)據(jù)還表明，睡眠不足與高密度脂蛋白水平低下有關，這種“有益的”膽固醇負責清除血液中有害的膽固醇并降低患心臟病的風險。

Overall it's more evidence for the positive benefits of banking seven, eight, or nine hours sleep instead of six a night – the researchers suggest the perfect amount is somewhere inside that range, depending on the person.
總的來說，每晚睡7，8或9個小時要比睡6個小時有益。研究人員建議，根據(jù)每個人的情況，每晚睡7～9個小時最合適。

The researchers also say their findings could provide new insight into the relationship between sleep and metabolic diseases like diabetes, which now affects more than 422 million people worldwide, according to the World Health Organisation.
研究人員還表示，他們的發(fā)現(xiàn)使人們對睡眠與糖尿病等新陳代謝類疾病之間的關系有了新的見解。據(jù)世界衛(wèi)生組織報道，如今逾4.22億人正受到糖尿病的困擾。

The hope is if we understand more about the causes of obesity – such as reduced amounts of sleep– then we're better able to tackle it and the related health issues.
如果我們更了解肥胖的起因，例如睡眠不足，我們就有望更好地解決肥胖和相關的健康問題。

"Understanding why people gain weight has crucial implications for public health," the researcher said.
“明白人們?yōu)槭裁磿L胖對改善公眾健康有重要作用?！毖芯咳藛T說道。
