A recent meta-analysis of research concerning the duration of sleep due to the risk of cardiovascular disease, left no doubt: today in CVD risk were those who enough sleep, and those who sleeping too long. The optimal amount of daily sleep was called 6-8-hour period.
BUT National Sleep Foundation (USA) has published its data: modern adult person needs 7-9 hours a day full of sleep. He is equally harmful lack of sleep and oversleeping. They are able to trigger the metabolic syndrome forty years abroad, whose symptoms are:
- the formation of body fat;
- failure fat / carbon exchange;
- arterial hypertension;
- insulin resistance.
Lack of sleep is fraught with more and intrusive thoughts, anxiety, depression. Lack of sleep - one of the most important risk factors for Alzheimer's disease.
The team of Greek scientists from the Center for Cardiac Surgery Onassi (Athens) this year reviewed A number of studies on the impact of the amount of sleep on the occurrence and development of heart disease, vessels. The projects on the issue involved more than half a million adults with cardiovascular disease, diagnosed in the last 5 years. Between themselves scientists compared figures 3 groups consisting of patients sleeping per day:
- less than 6 hours;
- more than 8 hours;
- from 6 to 8 hours.
The result was revealed the high risk of CHD (coronary heart disease), and death from the disease, or a stroke, it is associated with lack / excess of daily sleep. At the same time those who are vacationing less than 6 hours, the risk increased by only 11%, but in those who slept longer than 8 hours - all 33%.
It should be noted that the main advantage of the meta-analysis performed by scientists from Greece, is the fact of inclusion in it only prospective studies - that is, those in which physicians themselves observed for the control of human cohorts. And it is possible to avoid the "memory error" caused by a failure in the completeness or accuracy of the memories of past events already.
Recall: in the world today cardiovascular disease came out on top in the number of causes of death and disability. And women in the year after diagnosis of heart failure die more often than men. Therefore, the results of research in this area should pay special attention. And they suggest:
- need to sleep 6-8 hours a day;
- you need to eat more eggs;
- it is necessary to control the amount of salt eaten;
- should go as often and quickly as possible.
