it is easy to death if one lack of sleep a day 6

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.

 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.

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.

” 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.

 “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.”







那些夜晚睡眠时间超过9小时的人早逝的可能性增加30%。研究刊登在《睡眠》周刊上。 然而,上周《睡眠》周刊上一篇研究报告的结论则与之背道而驰,该报告则称,夜晚睡眠10小时甚至更长的人更有可能活到100岁。
