How to sleep for good health?
After much research it became apparent that most healthy people can be considered, which usually sleep 6, 5-7, 5 hours. They have the lowest rate of cardiovascular disease and mortality. At the same ones who sleep less than 4, 5:00, shortened life expectancy by an average of 1, 6 times. Observations showed that more than 9 regularly even more dangerous to sleep 5 hours - it shortens the life of 1, 7-1, 9 times.
Pattern identified, but to explain why there is so, scientists have not yet taken. If too short sleep more or less clear - from insufficient rest the body wears out faster, the causes of high mortality among heavy dormice remain a mystery. Perhaps we are talking about the feedback - too much sleep those whose health is not all right. However, doctors are reminded that universal recommendations for the duration of sleep, they can not give. It is only the time necessary and sufficient for most people. For each person has its own optimum sleep duration, depending on lifestyle, occupation, health, and even the climate of the country in which he lives. See also:
