Too much sleep could be linked to heart problems and premature death, research has revealed.
研究表明，睡得太多可能會導(dǎo)致心臟病或早逝。

A study found people who slept longer than eight hours had a higher risk of dying or developing diseases of the heart or blood vessels in the brain compared to those who slept for between six and eight hours.
一項(xiàng)研究發(fā)現(xiàn)，與那些睡眠在6~8小時之間的人相比，睡眠超過8小時的人罹患心臟病或腦血管疾病或因此而死亡的機(jī)率更高。

“Sleep is essential to human health, and people spend about a third of their hours sleeping,” the team of international researchers wrote.
“睡眠對人類的健康是必要的，人一生中約三分之一的時間都在睡覺，”這個國際研究員團(tuán)隊(duì)寫道。

“It is increasingly regarded as an important lifestyle behaviour that can affect cardiovascular disease (CVD) and death.”
“睡眠已日益被當(dāng)成能夠引起心血管疾病和死亡的一種重要的生活行為。”

Compared to people who slept six to eight hours, those who slept a total of eight to nine hours a day had a 5 per cent increased risk.
與那些一天睡眠在6~8小時之間的人相比，睡眠在8~9小時的人罹患心血管疾病的機(jī)率要高5%。

Those sleeping between nine and 10 hours a day had an increased risk of 17 per cent – and those sleeping more than 10 hours a day carried a 41 per cent increased risk of cardiovascular disease or death.
那些一天睡眠在9~10小時之間的人罹患心血管疾病或死亡的機(jī)率要高17%，而那些睡眠超過10小時的人患病或死亡的機(jī)率則要高41%。

The researchers also found a 9 per cent increased risk for people who slept a total of six or fewer hours.
研究人員還發(fā)現(xiàn)，睡眠為6小時或不足六小時的人患病的風(fēng)險要高9%。

Lead researcher Chuangshi Wang said: “Our study shows that the optimal duration of estimated sleep is six to eight hours per day for adults.”
這項(xiàng)研究的主導(dǎo)研究員王創(chuàng)時表示，“我們的研究表明，成年人一天睡眠的預(yù)估最佳時長是6~8小時?！?/div>

Co- researcher Professor Salim Yusuf added: “The general public should ensure that they get about six to eight hours of sleep a day.
共同研究員薩利姆·約瑟夫教授補(bǔ)充道：“公眾應(yīng)確保自己每天睡6~8小時。

“On the other hand, if you sleep too much regularly, say more than nine hours a day, then you may want to visit a doctor to check your overall health.”
“否則，如果你經(jīng)常睡太久，例如一天超過9小時，那么你可能需要去看醫(yī)生，檢查一下自己整體的健康狀況?！?/div>
