You need to sleep in moderation

Having less than seven and a half hours' sleep a night 'quadruples heart attack risk'

Translation: Inopressa http://www.inopressa.ru/Those who sleep less than 7.5 hours a day are "four times more likely to have a heart attack." 

These are the data of a recent study by Japanese scientists led by Dr. Katsuo Eguchi, the results of which are reported by The Daily Mail.

(It seems that there is some confusion in the title and it should be read not "four times, but "by a quarter". In any case, judging by the retelling of the results of the study - VM.)

The study involved 1,255 patients with high blood pressure aged 33 to 97 years (the average age of the subjects was 70 years). On average, each of them was observed for a little less than two years.

Of these, 1007 people slept more than 7.5 hours a day, and 248 less. Those who did not get enough sleep had a 27% increased risk of heart attack and stroke. An even more ominous prognosis awaited those representatives of the second group who had blood pressure jumping at night (there were 20 of them).

The report on the results of the study is published in the Archives of Internal Medicine. Scientists note that in the modern world, lack of sleep has become a common phenomenon, and it is with him that the risk of exacerbation of a number of cardiovascular diseases may be associated. However, according to The Daily Mail, Eguchi and his colleagues admit that the study involved mostly elderly people, and its results are less relevant for young people.

The situation is even worse with those who sleep five hours or less, the newspaper claims, citing experts from the University of Warwick. Such people have a 70% increased risk of death in principle, and the risk of dying from heart problems doubles. However, according to their data, sleeping more than eight hours is also very harmful: the chances of dying double.

Previous studies have shown that lack of sleep explains the tendency to obesity, high blood pressure and type 2 diabetes, recalls the British edition.
