The doctor warned: 5 small things can make the heart and brain blood vessels “collapse” instantly!


Few people know that more than one-third of cardiovascular and cerebrovascular diseases accidentally occur in the hot summer.
Guo Jun, the chief physician of the Department of Cardiology of the First Affiliated Hospital of Jinan University, said that in the past, cardiovascular and cerebrovascular diseases were considered the most dangerous in winter, but in fact, in the hot summer, especially after the temperature exceeds 35 ℃, the subcutaneous blood vessels of the human body dilate and the skin bloodThe flow rate will be 3-5 times faster than usual. The blood flow back to the heart increases. One of the most significant changes is that the burden on the heart becomes heavier. In addition, at high temperatures, the internal environment of the human body is easily disturbed, sympathetic nerve tension increases, and the heart rate naturally accelerates.Coronary arteries tend to contract, and the workload of the heart is several times greater than usual.There is a lot of sweating in the summer, the body’s water will evaporate with the sweat, and the blood becomes thick. Accidentally, it will lead to the formation of plaque thrombosis. The next step is to cause myocardial infarction or stroke, and the quality of sleep in summer is generally poorIt is also one of the triggers for the unexpected occurrence of cardiovascular and cerebrovascular diseases.Experts suggest that to prevent the onset of cardiovascular and cerebrovascular diseases in the summer, blood pressure and heart rate must be monitored, especially for the elderly. Within 1 hour after getting up in the morning and before going to bed at night, you can measure whether the blood pressure is below 140 / 90mmHg, and the heart rate is 70 ~80 times / minute.These five small things will make the cardiovascular and cerebrovascular vessels collapse instantaneously. In addition to preventive work, for people with basic chronic diseases, there are certain behaviors to pay special attention to in the summer, because carelessness can easily lead to cardiovascular and cerebrovascular diseases.The state of “collapse”: First, drink cold drinks immediately after exercise on a hot summer day, many people like a bottle of cold ice after a vigorous exercise, a refreshing and cool drink, but this sudden cold stimulation is the easiestIt causes contraction of the peripheral blood vessels of the human body, causing a sudden rise in blood pressure, even transient coronary spasm of the coronary arteries, rupture of the plaque, and formation of thrombosis. Eventually, almost all of them are caused by sudden cardiac death through malignant arrhythmia.This situation also occurs when the hot and cold environment changes suddenly, such as entering an air-conditioned room and taking a cold shower.Second, when you look back suddenly, many people have a cardio-cerebrovascular accident when they suddenly exert force or get up suddenly, which is mainly caused by carotid artery stenosis or plaque exfoliation.In summer, the human body is prone to lack of blood volume, and the blood viscosity is intensified. A sudden turn back or a sudden rise to the head can easily make the carotid plaques fall off, causing cerebral infarction. If the plaques reach the heart with the blood vessels, It will cause myocardial infarction, these are minutes of life.3. Eating too full In fact, after a meal is a high incidence of cardiovascular and cerebrovascular accidents.This is because after the meal, the nerve center will receive instructions to allocate blood to the digestive system that needs to work, such as the stomach and intestines, resulting in ischemia of the heart and brain and relatively low oxygen supply, which is why there are manyThe reason why people are easily sleepy after eating.However, if the patient has high blood pressure and heart function problems at this time, if he is too full, he will easily have problems. After eating too much, the diaphragm will rise, and the feeling is that the stomach is against the lungs, and the respiratory function is blocked, causing accidents.Said that it is recommended that people who prevent the onset of cardiovascular and cerebrovascular diseases should eat less and eat more meals in summer, and only eat half-full for each meal. Do not rush to exercise after a meal.4. Excessive defecation. Doctors often warn some elderly people to actively prevent constipation and not to exert too much force on defecation.This is because many of the causes of cardiovascular and cerebrovascular accidents are related to forced bowel movements. Experts say this is mainly divided into several situations. One is that when forced bowel movements will cause abdominal pressure to increase, increasing the resistance of the heart to drain blood.That is to say, the blood pressure will rise suddenly. If the change is too fast, it may cause severe hypoxia of the heart and brain in a short period of time, causing cerebral hemorrhage, angina, and myocardial infarction.Another situation is that some elderly people have heart problems themselves. The coronary arteries are very narrow. The blood pressure suddenly increases, and the heart load becomes larger. This causes insufficient myocardial oxygen supply and induces myocardial infarction.In addition, the elderly have poor vascular sclerosis. After excessive exertion of bowel movements, they suddenly stand up and their blood pressure drops, causing orthostatic hypotension, insufficient blood supply to the brain, and dizziness, blurred vision, and even fainting.5. Forget to drink water in summer, remember to drink more water.

Under high temperature, the body’s water will be evaporated a lot. Once the water is not filled in time, it is easy to cause the blood viscosity to increase, and cardiovascular and cerebrovascular diseases occur frequently.The doctor recommends that the daily water consumption in summer is generally more than 2000 ml. It is best to drink a glass of water before going to bed or in the morning to relieve the blood concentration in the day.In addition, the summer people themselves are prone to emotional ups and downs, and drinking more water can also calm down their mood.
