The dream, so that we needed it, reason why can be difficult to obtain, and how it affects everything, from the sport yield of our personal success and the health, he is one of the most burning subjects of the today science.
In 2002 a study in the Scripts Clinic Sleep Center in the Jolla, California, compared the rates of death between more than 1 million adult Americans. The adults were part of a study on the prevention of the cancer and are forced to inform into their average amount of dream every night. At the moment the results of the study of Scrips were surprising, but since then it has been corroborated by studies in Europe and Eastern Asia.
So How much dream is ideal
In agreement with studies of the people who sleep between 6,5 and 7,5 hours per live night by more time. The people who sleep 8 hours or more or less of 6,5 hours have minor life expectancy. It seems that there is evidence that supports that it is not as much risk throughout sleeping, since is in minors to sleep.
It can be interesting to observe that the long dream begins to the eight hours and to sleep 8.5 hours really could be a little worse than to sleep five hours per night.
We only can guess so that the people who sleep 6.5 to 7.5 hours, one night, to live more time, but we really do not know to the cause or the effect.
