People who sleep fewer than six hours a night are more likely to die early, researchers have found in a study they claim provides 'unequivocal evidence' of a link between sleep deprivation and premature death.
They discovered that people who slept for less than six hours each night were 12 per cent more likely to die prematurely - before the age of 65 - than those who slept the recommended six to eight hours a night.
由英国华威大学和意大利那不勒斯市的费德里克二世大学联合组成的研究团队在分析了16个研究项目之后得出了以上结论。项目共涉及130万人。 The team from the University of Warwick and Federico II University Medical School in Naples analysed 16 studies involving a total of 1.3 million people before reaching their conclusions.
They pointed out that previous studies had shown that sleep deprivation was associated with heart disease, high blood pressure, obesity, type 2 diabetes, and high cholesterol.
However, the researchers also found that sleeping too much was linked to an early death.
Those who slept for more than nine hours a night were 30 per cent more likely to die early, the research published in the journal Sleep found.
That directly contradicts research published in the same journal last week which suggested that people who slept for ten hours or longer a night were more likely to live to 100.
This was thought to be because people who lived into extreme old age were healthier and therefore slept better.
然而，参与最新研究的专家并不认同这种观点。他们认为，睡眠过长是潜在疾病的征兆，比如抑郁或体力下降，一些癌症也与睡眠过长有关。 However, the authors of the latest research contradicted this and suggested that long sleep was a sign of underlying illnesses such as depression and low levels of physical activity. Some cancer is also associated with sleeping for longer. 更多信息请访问：http://www.24en.com/
Professor Francesco Cappuccio, leader of the Sleep, Health and Society Programme at the University of Warwick and Consultant Physician at the University Hospitals Coventry and Warwickshire NHS Trust, said: "Whilst short sleep may represent a cause of ill-health, long sleep is believed to represent more an indicator of ill-health.
"Modern society has seen a gradual reduction in the average amount of sleep people take, and this pattern is more common among full-time workers, suggesting that it may be due to societal pressures for longer working hours and more shift-work. On the other hand, the deterioration of our health status is often accompanied by an extension of our sleeping time.
“长期坚持每晚睡眠6至8小时可能最有益于健康。持续睡眠时间的长短应被视为另外一种行为风险因素，或者风险标志。它受环境影响，可能通过教育、辅导以及改善工作环境等提高公众健康水平的途径而被改变。” "Consistently sleeping six to eight hours per night may be optimal for health. The duration of sleep should be regarded as an additional behavioural risk factor, or risk marker, influenced by the environment and possibly amenable to change through both education and counselling as well as through measures of public health aimed at favourable modifications of the physical and working environments."
