Scientists have finally figured out how much time it takes to sleep a person to live as long as possible and at the same time to stay healthy for a long time - about seven hours a day, according to an Internet publication for girls and women from 14 to 35 years old Pannochka. Net We have no reason not to believe this, because these studies were conducted by well-known experts on longevity - the Japanese. A group of doctors from the University of Nagoya, led by Professor Akiko Tamakoshi from 1988 to 1999. Conducted close monitoring of the lives of 110 thousand people from 45 regions of the Land of the Rising Sun. For the next ten years, the scientists processed the results, studying the effect of sleep duration on morbidity, stress development and mortality - in fact many participants in studies 15 years ago had already gone to a different world.

As it turned out, the most healthy were people who usually slept 6. 5-7. 5 hours, in this group and the death rate was the lowest. Those who slept less than 4. 5 hours, life expectancy decreased by an average of 1. 6 times, it is even more dangerous, as the experiment has shown, to regularly sleep more than 9. 5 hours - this shortens life in 1. 7-1. 9 times. The pattern is revealed, but to explain why this is happening, the Japanese are not yet taken. If with too short a dream everything is more or less clear - from an inadequate rest the organism wears out more quickly, then the causes of high mortality among sleepers are not at all obvious.

Perhaps it is a question of feedback - too many people are sleeping, with health in which everything is not all right. At the same time, scientists recall that they can not give a universal prescription for the duration of sleep, it is only a matter of time that is necessary and sufficient for most people. For each person, in fact, there is an ideal duration of sleep, depending on the lifestyle, occupation, health status and even the climate of the country in which he lives medicinform. Net.
