American scientists from the Harvard School of Medicine came to a disappointing conclusion: the poor quality of sleep leads to hypertension , Which is especially dangerous for the elderly, which usually do not sleep so deep and long-lasting as that of the young or middle-aged people. The risk of hypertension in this case is increased by 83%.

Journal of Hypertension published an interesting experiment on the study of American Scientists. The group has 784 men over 65 years for 3 years with special instruments measured the quality of sleep. At the beginning of the experiment, none of them suffered pressurized But to the end the results were not so joyful: 243 people began to suffer from hypertension.

The volunteers were divided into several groups, which are formed depending on the depth of sleep. The first patients were, deep sleep of not more than four per cent of the total sleep time. In the other group there were men who have the dream was 17%. Based on the experiment, doctors conclude that the risk of hypertension increased by almost 2 times, if your dream is short and shallow.

Scientists believe that such a link hypertension to the phases of sleep is present not only men but also women. They said only that at the moment remains to investigate whether there is such a dependence in young and middle-aged.

"It has long been known that sleep is very important for health. It should be a priority, and the people should always remember that sleeping less than 7 hours, especially in old age, can really be dangerous "- says Natasha Stewart, senior nurse at the British fund the study of heart disease.
