People who used to go to bed early and, accordingly, to wake up early, more likely to develop diseases of the cardiovascular system than those who like to lie in bed a little longer. This is reported by scientists from Japan.

Researchers from several medical and scientific institutions Japanese city of Kyoto   through observations determined that the period of morning awakening and functioning of the human heart and blood vessels are closely linked.

People who are forced to climb out of bed very early to go to work or to do jogging, are at risk of heart ailments.

After a study of the health of more than 4000 volunteers Whose age ranged from 23 to 90 years , Scientists have determined that " larks "Often suffer myocardial infarction   and hypertension . In addition, scientists have noted that among the early risers is dominated by older people.

According to Japanese scientists, the constant lack of sleep increases the load on the heart, which ultimately can lead not only to serious diseases, but also in death.

Significantly reduce the probability of such serious health effects allow naps. Scientists say that even sleep for half an hour three times a week can reduce a third chances of having a heart attack. Explain a pattern that sleep during the day can significantly reduce the level of Cortisol   ( stress hormone ) in blood.

And according to scientists Switzerland   restful sleep can improve the communication between nerve cells in the human brain. To confirm this theory, it was conducted a special experiment, which was attended by three groups of people that perform a variety of tasks, and view images. Volunteers from the first group slept for eight hours, people from the second group - just a little nap, and those who were in the third group, did not sleep at all.

One day all the participants of the experiment were to re-execute the task given to them and remember those pictures that they showed on the first day. Volunteers, sleep well, we showed the best results, while scanning their brain activity was marked by the greatest. As a result, the researchers concluded that sleep can significantly improve the communication of brain nerve cells, and in the process of sleep obtained information "fixed." To do this, a person should sleep every day not less than eight hours.
