Scientists: 8 hours sleep is fraught with stroke, enough for a 7– RosRegistr

If you sleep more than 8 hours a day, it may indicate the propensity to stroke. About the same time, scientists have warned the elderly. They insist that long sleep is a sign of ill health, the newspaper writes the BBC.

In order to confirm their assumptions, scientists from the British university conducted a study which lasted several years. They found that those who sleep more than eight hours, the risk of stroke is increased by fifty percent. But at risk are those who sleep less than 6 hours – these people are 18% more at risk of stroke than those who sleep of the rules of the time.

A scientist from the Center of sleep disorders Greg Jacobs argues that for the health of the most useful seven o’clock night’s sleep. But more or less time to sleep very early increases the chances of death. The findings of scientists from the University of Massachusetts made based on a decade of research.

« A total of 34 different studies, – says Greg Jacobs. – Doctors monitored behaviors and health status of more than two million people. It turned out that the relationship between sleep duration and life expectancy can be represented in the form of the letter «U».

«The lowest mortality observed in the lowest part of the arc« U », and this point corresponds to seven hours of daily sleep. Once you begin to move away from the ideal of how to more prolonged sleep and sleep deprivation aside, the risk of early death begins to grow. The risk increases with fans to sleep faster than those who sleep less than normal ».

But according to the Internet newspaper Neelov, Franco Cappuccino, professor of cardiovascular medicine at the British University, says that panic not worth it. He argues that sleep in the range between 6 and 8 hours is the norm and to human health does not threatened. He says that to measure the exact duration of sleep is almost impossible, the more trusting the words of the people studied. After all, none of them can not accurately be called not only the number of hours and minutes, the duration of their sleep.
