It is established that between eating and having a meal, there must be a break. It positively affects the state of the cardiovascular system.
The most common heart and blood vessels presently are stroke and acute coronary syndrome.
A stroke is an acute cerebrovascular disruption that occurs when the vessels of the brain are clogged with a thrombus or against a background of bleeding into the substance of the brain.
Acute coronary syndrome is understood to include violations such as unstable angina and myocardial infarction, which develop when the blood supply to the heart decreases against the background of atherosclerosis and other vascular diseases.
As scientists from the Medical School of the University of Janina (Greece) have found, the development of these diseases, in addition to already known risk factors, promotes sleep after a large meal. Moreover, the more time passes after a meal, the lower the risk of acute cardiovascular disorders.
The results of their study, presented by scientists at the Congress of the European Cardiology Society, which was held in late August in Paris.
The study was attended by 500 healthy volunteers who never complained of heart and blood vessels, 250 stroke patients and 250 people with acute coronary syndrome.
All participants completed questionnaires, which indicated their sleep-waking habits after eating.
As it turned out, the highest risk of developing cardiovascular disorders is noted among those who fall into bed immediately or within an hour after eating.
If people could wait 60-70 minutes before going to bed after dinner, this reduced the risk of stroke by 66%, with each additional 20 minutes helping reduce the risk by another 10%. Two hours later, the likelihood of developing acute diseases became the same as in healthy volunteers.
Scientists have taken into account other factors of the risk of developing heart disease and stroke: gender, age, level of physical activity, excess body weight, smoking, hypertension, high cholesterol, diabetes mellitus. However, in some people, these risk factors were absent, and acute circulatory disorders still evolved. This helped researchers to conclude that the rate of sleep deprivation in some way affects the state of the heart and blood vessels.
Why is it so important to eat after eating
The objective analysis of the causes of the revealed relationship was not carried out by scientists.
However, according to a leading researcher dietitian Christina Maria Kastorini, all the fault may be acid reflux, that is, throwing gastric contents into the esophagus. This condition often develops in those cases when a person after a meal, especially after taking abundant and fatty food, quickly takes a horizontal position.
Past studies have shown that reflux increases the risk of developing obstructive sleep apnea, which in turn is associated with a stroke probability.
According to another theory, metabolic changes that accompany food intake play a role. After food, the concentration of sugar in the blood increases rapidly, the amount of fat and cholesterol changes, fluctuations of blood pressure arise. All these temporary factors can affect the risk of acute blood disorders.
That is why it is not necessary to violate all known rule: between the last meal and going to sleep should be a break of at least two hours.
