Lack of sleep may be deadly, research shows
People who get too few Zzzz’s twice as likely to die of heart disease
People who do not get enough sleep are more than twice as likely to die of heart disease, according to a large British study released on Monday.
Although the reasons are unclear, researchers said lack of sleep appeared to be linked to increased blood pressure, which is known to raise the risk of heart attacks and stroke.
A 17-year analysis of 10,000 government workers showed those who cut their sleeping from seven hours a night to five or less faced a 1.7-fold increased risk in mortality from all causes and more than double the risk of cardiovascular death.
The findings highlight a danger in busy modern lifestyles, Francesco Cappuccio, professor of cardiovascular medicine at the University of Warwick’s medical school, told the annual conference of the British Sleep Society in Cambridge.
“A third of the population of the U.K. and over 40 percent in the U.S. regularly sleep less than five hours a night, so it is not a trivial problem,” he said in a telephone interview.
“The current pressures in society to cut out sleep, in order to squeeze in more, may not be a good idea — particularly if you go below five hours.”
