People who sleep fewer than six hours a night are more likely to die early, researchers in University of Warwick have found in a recent study. They discovered that people who slept for less than six hours each night were 12% more likely to die before the age of 65 than those who slept the recommended six to eight hours a night.
The researchers pointed out that previous studies had shown that the lack of sleep was associated with problems like heart disease and high blood pressure. 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% more likely to die early, as an article in the latest Sleep suggested. That directly contradicts another passage in the same journal last month suggesting 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. Professor Francesco Cappuccio at the University of Warwick said: “ While short sleep may represent a cause of ill-health, long sleep is believed to represent more an indicator of ill-health.”
He also mentioned: “ 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 social pressures for longer working hours. On the other hand, the worsening of our health is often accompanied by an extension of our sleeping time.”
“Consistently sleeping six to eight hours per night may be good for health. However, whether to achieve the goal depends on various factors such as the environment as well as measures of public health aimed at favourable changes of the working environments,” Professor Francesco Cappuccio added.
