1, meals big fish and meat blood vessels are easy to block young people in the more socializing, restaurant dishes thick oil and red sauce, mostly with high oil, high salt, high sugar cooking, long-term consumption leads to more and more fat in the blood vessels, easily caused by blood vessel blockage. 2, day and night reversal disrupts the human biological clock young people tend to become “stay up late a family”. From the health point of view, eleven o’clock at night to five o’clock in the morning, is the liver metabolism time. Staying up late disrupts the body’s biological clock, resulting in excessive secretion of adrenaline and norepinephrine, causing vasoconstriction, resulting in an increase in blood viscosity, flow restriction. Long-term black and white people, the risk of heart disease than normal people will double. 3, smoking is easy to leave hidden problems to the blood vessels Smoking is one of the culprits that lead to blood vessel malfunction, even if you are in good health, it will leave hidden problems to the blood vessels. Scientific research shows that smoking more than 20 cigarettes a day, the risk of coronary heart disease will increase 2-3 times. There are also studies that found that smoking when staying up late, will make the blood viscosity than normal rise more than 8 times. 4, less exercise leads to increased vascular garbage Lower extremity blood vessels are very important, but often overlooked. If the cerebral blood vessels have problems, the chances of heart disease is 2 – 3 times the normal person, if the lower extremity blood vessels have problems, the chances of this will become 4 times. Normal people have about 600 capillaries per square millimeter of skin, usually only open 100 – 200, more exercise can make more capillaries open, promote blood microcirculation; and long-term non-exercise, blood vessels within the garbage will gradually accumulate, the formation of atherosclerotic plaques, “time bomb”, may be detonated at any time. 5, hypertension, diabetes drag cardiovascular and cerebral vessels without symptoms or uncontrolled hypertension, is the trigger of many vascular disease fuse. High blood pressure patients have a 4–7 times higher chance of having a cerebral infarction than normal people. Hyperglycemia not only involves the microvessels, but also leads to macrovascular disease. People with high blood sugar have a 2–3 times higher incidence of stroke than normal people. Bad mood hurts blood vessels. Experts have confirmed that mental stress can cause endothelial contraction and accelerate vascular aging.
