The heart, which supplies blood to the whole body, seems to be strong but is actually fragile. Today summarizes the summary of the heart more vulnerable 6 time periods, teach you how to protect the heart strong heart. 1, after overeating. In order to digest food, a large amount of blood to the gastrointestinal transfer, the supply of blood to the heart is relatively reduced, thus aggravating myocardial ischemia, increasing the burden on the heart. If you eat too greasy and consume too much fat, it may also lead to an increase in blood viscosity, promote thrombosis and trigger myocardial infarction. Therefore, it is best to eat seven or eight minutes full at each meal, and control fatty meat, animal offal and other high triglyceride, high cholesterol food. If you often have chest tightness, chest pain, rapid heartbeat and other discomforts after a full meal, you need to go to the hospital in time to rule out heart problems. 2, forceful defecation. Need to hold your breath, abdominal wall muscles and diaphragm will be strongly contracted, so that the abdominal pressure rises, then caused a sudden rise in blood pressure, myocardial oxygen consumption increases, induced angina pectoris, myocardial infarction and serious arrhythmia, severe cases may cause sudden death. Even if the stool is dry and difficult to discharge, do not force too much, if necessary, can be used to cope with the auxiliary methods such as Kaiser Permanente. In order to ensure smooth stools, it is usually best to eat more dietary fiber-rich fresh fruits and vegetables and coarse grains, should also drink more water, moderate exercise. 3, when strenuous exercise. Appropriate exercise contributes to physical and mental health, but strenuous exercise will force the heart horsepower full open, each time the contraction of a few times more blood to the whole body, so it is easy to cause a sudden rise in blood pressure, heart rate is too fast, myocardial hypoxia, and even lead to a heart attack. It is best to carry out a more moderate aerobic exercise such as fast walking, jogging, etc. It is best for the elderly and those with a bad heart not to participate in competitive sports. Exercise heart rate should not exceed the target heart rate (40 years of age with 180 minus age, 40 years of age with 170 minus age), and exercise time should not be too long, about half an hour is appropriate. If chest tightness, shortness of breath and other discomforts occur during exercise, you should sit down and rest immediately. 4, stress, mental tension. Heart health and psychological and mental state is closely linked. When the work pressure is high and the mood is tense, the nervous system is disturbed, then it will affect the working condition of the heart. For example, a healthy person in nervousness, there will be a red face, rapid heartbeat, blood pressure rise and other phenomena; change into the heart function is not good, there may be a hard chest, sudden heart attack and other problems. People should learn to release the pressure, in time to the worries, grievances and other undesirable factors out. When you are nervous, stand naturally, close your eyes and do a deep whistle, which helps to relax your body and mind. 5, every morning from 6:00 to 12:00. Spain’s National Center for Cardiovascular Research analyzed the data of more than 800 heart attack patients, found that the number of patients from 6 a.m. to 12 p.m. at this time of the year the largest number of patients, and the condition is more serious. Harvard University study also pointed out that the risk of heart attack in the morning is 40% higher than other times. The reason for this is that after getting up in the morning, the body secretes adrenaline and other stress hormones, resulting in increased blood pressure, coupled with no water throughout the night, the blood is thicker, prone to embolism. After waking up in the morning, it is best to move gently and slowly, but also timely hydration. Hypertensive patients need to follow the doctor’s instructions to see if you need to take a long-acting antihypertensive drug before bedtime, in order to better control the next morning’s blood pressure. 6. November to March each year. A number of international studies have found that, seasonally, winter (usually November through March) is the peak time for heart attacks, and for every 10 degrees Celsius drop in temperature, the risk of heart attack rises by 7%. The reason for this is that in winter, human physiology reacts more slowly and is often in a state of stress, thus increasing the load on the heart. In addition, the temperature difference between outdoor is very large, when you go out, the blood vessels are stimulated by cold air, easy to sudden contraction, resulting in blood supply interruption or vascular blockage, causing myocardial infarction or stroke. When you go out, you should keep warm and protect your head, hands and feet. Even when you return to the warmth of the room, you should not be in a hurry to take off your clothes and hats to minimize fluctuations in blood pressure.
