Get Some Sleep

Researchers have identified what they believe is the most healthful length for sleeping: between six and eight hours per day. More specifically, they concluded that short sleep increases the risk for death and that over long sleep may indicate serious illness. Following is a news release on the study from the University of Warwick in the United Kingdom:

Research carried out by the University of Warwick in collaboration with the Federico II University Medical School in Naples, Italy, has found that people who sleep for less than six hours each night were 12 percent more likely to die prematurely than those who get the recommended six to eight hours.

The study, published in the journal Sleep, provides unequivocal evidence of the direct link between short duration of sleep (less than six hours sleep a night) and an increased chance of dying prematurely.

The research also notes that consistent over long sleeping (over nine hours a night) can be a cause for concern. While, unlike short sleeping, over long sleeping does not in itself increase the risk of death, it can be a significant marker of an underlying serious and potentially fatal illness.

The study looked at the relationship between the level of habitual duration of sleep and mortality by reviewing 16 prospective studies from the UK, USA, European and East Asian countries. The study included more than 1.3 million participants, followed-up for up to 25 years, with more than 100,000 deaths recorded.

This study provides unequivocal evidence of the direct link between both short (less than six hours sleep a night) and long (nine hours or more) duration of sleep and an increased chance of dying prematurely, compared to those who sleep six to eight hours a night on average.

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."

He said: "Modern society has seen a gradual reduction in the average amount of sleep people take, and this pattern is more common amongst 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," he continued. "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 counseling as well as through measures of public health aimed at favourable modifications of the physical and working environments."
