1, meal big fish and meat, blood vessels easily blocked. People in their thirties and forties often socialize outside, and the dishes in restaurants are mostly made with “high oil, high salt, high sugar” and “thick oil and sauce”, resulting in more and more fat in the blood vessels, which can easily block the blood vessels. 2, day and night reversal, disrupting the biological clock of blood vessels. Most people over the age of thirty are the mainstay of the unit, and inevitably become “late night people”. From a health perspective, 11 p.m. to 4 or 5 a.m. is the time to ensure that the liver metabolizes blood flow. When you stay up late, not only yourself, the cardiovascular biological clock will also be disrupted, resulting in excessive secretion of adrenaline and norepinephrine in the body, so that blood vessels constrict, blood flow is slow and viscosity increases. Long-term “black and white” people, the risk of heart disease will be doubled than normal people. 3, two packs of cigarettes a day, blood vessels are prone to “poisoning”. “Smoking is one of the culprits that lead to blood vessel failure, even if your body is good, two packs of cigarettes a day, it will certainly give blood vessels to leave poison, so that it is vulnerable day by day.” Zhang Jiwei, director of vascular surgery at Renji Hospital affiliated with Shanghai Jiaotong University School of Medicine, said that more than 50 years of research by American scientists showed that smoking more than 20 cigarettes a day increases the risk of coronary heart disease by two to three times. There are also studies found that smoking while staying up late will make the viscosity of the blood more than 8 times higher than normal. 4, less exercise, more vascular waste. Lower extremity blood vessels are also important, but often ignored by everyone. If there is a problem with the cerebral vessels, the chances of heart disease are 2-3 times higher than normal, but if there is a problem with the blood vessels in the lower extremities, these chances will become 4 times higher. Normal people have about 600 capillaries per square millimeter of skin, usually only 100-200 open, more exercise can make more capillaries open to promote blood microcirculation; and long-term non-exercise, the garbage in the blood vessels will gradually accumulate, the formation of atherosclerotic plaque this “untimely bomb “, will also affect the capillary blood supply, and may be detonated at any time. 5, hypertension, diabetes dragging the cardiovascular. No symptoms or uncontrolled hypertension, is the trigger for many vascular disease. Patients with hypertension are 4-7 times more likely to have a brain infarction than normal people. High blood sugar not only involves the microvasculature, but also leads to macrovascular disease, and the incidence of stroke is 2-3 times higher than normal in people with high blood sugar. Bad mood hurts blood vessels. Experts have recently confirmed that mental stress can cause vascular intima contraction and accelerate vascular aging.
