Should the common sense of the older generation be believed?
Hunan has been experiencing high temperatures for several days. On the night of July 14, a 24-year-old man from Xiangjiang River in Zhuzhou suddenly fell to the ground while playing basketball outdoors. Witnesses said at the scene, “The weather was hot at the time. He played three or four groups and sat down. I didn’t walk around the court and drank ice water. I didn’t expect an accident.” The doctor reminded that high temperature is also a major cause of sudden death in summer, and the age group of sudden death has shown a younger trend. So what can cause sudden exercise death? How to avoid sudden exercise-induced death?

There may be many reasons for this man’s sudden death, but ice water is definitely not the main factor. It is currently speculated that the cause of death in this case may be related to high temperature and high-intensity exercise. These will greatly increase the body, especially the heart burden. In addition to the initial factors, the case itself must be considered. There are many possibilities for sudden death, such as coronary heart disease, hereditary arrhythmia, cerebral hemorrhage, pulmonary embolism and even bronchial asthma. Among them, sudden cardiac death has the largest proportion, accounting for 80% of non-accidental sudden deaths. In sudden cardiac death, about 5-25% of sudden cardiac death is caused by hereditary arrhythmia. However, the incidence of sudden cardiac death (SCD) in adolescents (3-25 years old) is very low, and there is no effective clinical data statistics in China. However, unlike the common cause of SCD in the elderly, ischemic heart disease, the cause of SCD in adolescents is more complicated. The top three common causes are organic heart disease, coronary artery abnormalities and hereditary arrhythmia syndromes. [1] Many of these are related to genetic inheritance. For example, in organic heart disease, the common arrhythmogenic right ventricular cardiomyopathy is a hereditary cardiomyopathy, which is one of the common causes of sudden death in adolescents and athletes. Others include dilated cardiomyopathy, hypertrophic cardiomyopathy, etc. In addition to this, hereditary primary arrhythmia is also one of the causes of adolescent SCD. This kind of disease is generally caused by gene mutations that cause ion channel dysfunction, and then a type of genetic disease in which abnormal electrical activity of the heart occurs. It has obvious familial clustering. Among the more common ones are long QT syndrome (LQTS), Brugada syndrome, pre-excitation syndrome, catecholamine-sensitive ventricular tachycardia and so on. The above may be the causes of sudden cardiac death that people usually don’t pay much attention to, especially for young people under the age of 25, the risk of sudden death still exists. At the same time, these can be heritable, especially hereditary. Primary arrhythmia is common in familial inheritance and cluster seizures and so on. Most of hereditary arrhythmias are autosomal dominant inheritance. If one parent is a patient, the child’s probability of getting the disease is 50%. So, seriously, if you have a history of related medical conditions in your family, especially if you have a history of multiple people, or have a clear genetic type of arrhythmia, it is highly recommended to do some genetic tests, especially those who like Marathon runners, those who love to stay up late, and those who like to drink big drinks. Many arrhythmias cannot be found in the hospital by an electrocardiogram, because if there is no attack, there will be no symptoms, and the attack may disappear.

After reading some of the answers, I can’t bear it anymore. If you say that long-term exercise in hot weather is dangerous, then it is quite reasonable; if you say that you have an insidious cardiovascular and cerebrovascular disease and die suddenly after strenuous exercise, it is also possible; it is possible to blame the death on the few mouthfuls of ice water. What the hell. This black pot of ice water is too wrong. In Gao Zan’s answer, there are people who even take the gastrointestinal discomfort of drinking ice water after exercise as evidence that ice water is “very dangerous”… The problem is that many people do not exercise even if they are in a cool and comfortable air-conditioned room. A few mouthfuls of ice water can cause gastrointestinal discomfort. Can it be said that “ice water is a dangerous lethal substance”? This is a typical wrong attribution. Many people think that drinking ice water is dangerous after strenuous exercise, probably because “the human body is in a state of stress or high body temperature after strenuous exercise. The sudden cooling after drinking ice water will bring strong stimulation to the human body and may induce danger.” This idea seems reasonable at first glance, but it is obviously not known how powerful the human body’s internal environment regulation ability is. I have seen a study before. If you have a body temperature of 36.5 degrees Celsius, even if you drink a few liters of ice water at 0 degrees Celsius, your core body temperature will not drop by more than 0.1 degrees Celsius. The irritation is dead, and it is obviously an underestimation of the adaptability brought to the human body by millions of years of evolution. Maybe people can’t help but think about the bar-what you are talking about is the situation of normal people drinking ice water. In this case, the guy who died suddenly after strenuous exercise is different from the situation in the resting state. So let’s talk about the other two examples of the “harm” of ice water to the human body under extreme conditions: If the Internet has memory, some people may remember the news a few days ago: How to treat “a man died of heatstroke and a body temperature of 42 degrees.” “? What’s the real situation? How should we prevent heat stroke in summer? ​ The previous incident occurred a few days ago. To put it simply, a male patient passed away after working for several hours in the high temperature world of Shenzhen. His body temperature was as high as 42 degrees Celsius before his death, which was a severe heat stroke. The most serious type-heat stroke. Compared with the current incident, is it somewhat similar: one is the unfortunate death of heat stroke (severe heat stroke) caused by working for a long time in a hot weather… the other is a sudden death after strenuous exercise on a hot day… in the back here In this incident, many people attribute the sudden death of the boy to the few mouthfuls of ice water that he drank after strenuous exercise on a hot day; but you should know that in the previous heat stroke death incident, ice water was the most effective rescue. One of the methods: The prognosis of heat stroke is very poor, the mortality and disability rate are high, but it is related to age, underlying diseases, maximum body temperature, and most importantly, it is related to the duration of high fever and rapid cooling. If it is not treated promptly and effectively, the case fatality rate will reach 80%. Regardless of intervention, about 20% of survivors have left brain damage. Some patients are left with renal insufficiency. Unstable body temperature can last for several weeks. Therefore, early detection and early treatment must be made. Once suspected heat stroke is suspected to occur in others or oneself, there is only one core principle of treatment-cooling down. Immediately starting to cool down quickly and actively is the most effective way to save lives. For patients with exertional heat stroke, cold water or ice water immersion is the preferred method. For patients with classic heat stroke, the skin can be soaked in cold water and fanned to cool down, and wet ice packs or chemical cold packs should be considered as an auxiliary cooling method. In general, the temperature can be stopped when the oral temperature or rectal temperature drops below 39 degrees Celsius (source: “Mersk Medical Diagnosis and Treatment Manual”, chapter on heat stroke). For severe heat stroke patients-that is, the body’s body temperature regulation mechanism has failed In the case of severe overheating of the human body-let alone drinking ice water, sometimes it is necessary to spray a large amount of ice water directly on the surface of the human body, or even directly soak the person in ice water to quickly reduce the overheated body temperature. There may be people who can’t help but think about it-saying that people are directly immersed in ice water, and people are not allowed to drink ice water. The problem is that people have severe heatstroke or even heat stroke, and they can still drink. ? If you can drink it, of course you have to drink it directly. This is life-saving. By the way, an interesting thing is that severe heatstroke and heat stroke are usually handed over to the Critical Care Medicine Department, which is the ICU, for treatment. During the ICU rotation in the past, an old doctor complained about the fact that he saw a boy with heat stroke in the Beiyi playground and asked someone to buy some ice water to drink and sprinkle to cool down. He was stopped by a bunch of old men and women. The reason was that the boy had a heat stroke. , Drinking ice water is too irritating, you have to drink hot water. The old doctor thought…I have saved more people with heatstroke in my life than you have heard of heatstroke…This is still the playground of the medical university. The old men and old ladies are either family members of doctors or faculty members of the medical university… Another use of ice water under stress is acute gastrointestinal bleeding: some patients with gastrointestinal ulcers or cirrhosis of gastric varices, in the case of acute gastrointestinal bleeding, a large amount of ice salt water can be used to help stop bleeding. . Of course, because of the rapid development of endoscopy technology, this method has been used less, but it does not mean that it cannot be used. After talking about the ice water, let’s talk about why the young man in this incident died suddenly. In fact, for the sudden death of young people, unless it is particularly extreme overwork or heavy exercise, it is almost always due to hidden underlying diseases… Cardiogenic, neurogenic, and occasionally metabolic causes. (Ketoacidosis, hypokalemia…) The young guy here is most likely to have hidden diseases, and the possibility of sudden death from exercise-related cardiac diseases is greater. Rickson is the case. As for ice water, I want to say that computers are not afraid of cold water. It is really impossible for humans who have evolved for millions of years to be afraid of a few mouthfuls of ice water. Whether you can drink ice water or not, in fact, you just need to abide by two principles: don’t drink unclean ice water; don’t drink if your gastrointestinal tract cannot stand it. People are really different. Some people, like me, drink ice water all year round. Some people may have gastrointestinal discomfort with both mouthfuls of ice water. In the latter case, don’t drink ice water. But it is really unnecessary to demonize ice water…

Many sudden deaths are inconclusive because there are very few autopsies. Some problems can be seen in the autopsy. The sudden death cases I have experienced are those who stay online for a few days, stay up late and stay up for a long time. Roommates call 120, so half-way people can’t do it. When I arrived at the hospital, I was exhausted. I also experienced light physical activity, fell directly to the ground, died a few hours after the rescue, and fell to the ground during work, not a high-intensity physical work, and my uncle fell directly to the ground after brushing his teeth, without saying a word, my sister At that time, he was only a few years old, alas, civil servants were still technical backbones. There is also a doctor in our teaching hospital who did not wake up after the night shift. When the teacher and classmates found him, everyone was cold. Alas, for the case mentioned by the subject, strictly speaking, high-intensity exercise, high temperature, and a lot of Sweating is all a trigger. As for drinking ice water, some respondent found the family member’s comment on station b. I think that if you drink ice water directly with ice ballast, it will still be irritating to the body to some extent, if it is just from the freezer Take it out, it should not have that great impact on the body. In my personal experience, even if you drink ice, it is better to drink slowly. Let’s talk about rescue. First aid requires very high skills for rescuers. Even for clinicians, it is not easy to complete the entire first aid process. The most ideal medical assistance is that after falling to the ground, someone with professional skills will apply artificial respiration and chest compressions after the assessment, while the AED can be used within a few minutes, if not, it can be sent to the hospital within a few minutes. , Otherwise, the heart will stop beating for a long time, it will definitely not be able to recover. A student I once rescued, I rushed to the scene in about a few minutes, gave a very standardized cardiopulmonary resuscitation, the chest cavity can be clearly seen bulging, heart pressure The frequency and depth of the video are no problem, but I still didn’t wake up in the end, which caused me to collapse during that time. Anyway, two sentence summary 1. Give artificial respiration and chest compressions in the shortest time, as well as AED. Within 5 minutes. 2. Send to the rescue room in the shortest time. If the on-site resuscitation is successful, it is okay to be sent to the hospital later, and if there is no response on the spot, then don’t waste a minute. The above two sentences really require the most ideal situation, and most of the scenes cannot do it. On-site first aid, in the case of purely human resources, can be rescued, generally not very serious cases, the heart has stopped beating, there is no active breathing, and only a few can be saved. I am going to rescue a patient with low blood pressure after anesthesia, a drop in heart rate, and other vital signs fluctuating greatly after the operation, but I have not rescued it. Alas, it’s really hard to be saved. Besides the public opinion environment, there are not many people who can come forward. Among them, there are a few people with professional skills.

I will post a paragraph on the treatment principle of heat stroke (heatstroke). Do you think that the hospital will save or harm people by handling it like this? Do you think drinking ice water on a hot day is a good thing or a bad thing? Currently available cooling methods on site include (but are not limited to): ① Evaporative cooling. Spraying with cold water or spraying water mist to the skin at the same time with continuous fan can achieve effective cooling…②Soak in cold water. This method is mainly used in EHS patients. Using the principle of conduction cooling, use large containers (such as bath tubs, tarps, pools) to immerse the patient under the neck in cold water (2~20℃). This may be the most efficient cooling method on site, with a cooling rate of 0.13~0.19 ℃/min, there is no significant difference in the cooling effect of cold water at different temperatures…… ③Ice compress cooling. Use the principle of conduction cooling to make the patient wear an ice cap or headrest ice pillow; or place an ice pack wrapped in gauze on the neck, groin (pay attention to protect the scrotum), underarms and other parts with rich blood vessels and faster heat dissipation. Cool down. It should be noted that each placement should not exceed 30 minutes. Pay attention to the changes in local skin color when applying ice to avoid frostbite. Because these methods can cause skin vasoconstriction, it is recommended to massage the skin vigorously while applying ice. In fact, the cooling effect of ice compress is not ideal, and the cooling rate is about 0.034℃/min. ④ Cool down in the body. Use 4~10℃ normal saline gastric tube lavage (quickly inject through gastric tube within 1 min, total 10ml/kg, aspirate after 1min, can be repeated many times); or rectal lavage (depth not less than 6cm, 15~20ml Inject the total amount of 200~500ml at a rate of 1~2min, and release after 1~2min. It can be repeated many times). Pay attention to the infusion speed not too fast during enema. Rapid intravenous infusion of cold saline at 4°C can also achieve effective cooling. It is especially suitable for EHS patients with dehydration and is often used as a part of comprehensive treatment. With reference to relevant literature, this consensus recommends infusion of 25ml/kg or a total of 1000~1500ml of 4℃ normal saline within 60 minutes. The key to this method is to maintain a fast infusion rate, otherwise the cooling effect will not be achieved. At the same time, attention should be paid to monitoring the core temperature to make it not lower than 38.5°C. If cold saline is not available on site, room temperature normal saline can also be used to help cool down. ⑤ Drug cooling…

This is not a medical profession, and cannot be directly concluded. Our previous basketball team also finished training. Some people like to drink ice drinks and ice water. I have never seen this happen. Personal feeling: 1. There may be cardiovascular disease. Basketball itself is strenuous exercise and the body load is heavy. The existence of cardiovascular disease can easily cause sudden cardiac death. 2. There is no cardiovascular disease. It is purely overload exercise. Overload exercise exceeds the capacity of heart circulation and cannot meet blood oxygen demand. Exercisers are prone to heart failure, interruption of cerebral blood flow, and sudden death. Cold drinks played a catalytic role in this process. Simply put some suggestions: 1. Try to warm up in advance and fully warm up can help us improve our heart and lung metabolism, so that when we are doing strenuous exercise, the body’s metabolic capacity is sufficient to meet the needs of exercise. 2. Before exercise, pay attention to the risk investigation and do a physical examination. Do not exercise vigorously with cardiovascular conditions. Regular physical examinations, especially cardiovascular system examinations, are carried out so that we can understand our own health status in time, if there is any heart problem. In addition, you should have heard of AED (Automatic External Defibrillator), and some sports venues should be installed if possible. This critical moment can really save lives. Danish football player Eriksson suddenly lost consciousness and fell to the ground during the European Cup. The medical staff used AED (Automatic External Defibrillator) equipment to defibrillate and rescue him. As for what AED specifically is: it is a medical device that can be used by non-professionals to rescue patients with sudden cardiac death. In the event of a sudden cardiac arrest, nearby witnesses can use this “life-saving artifact” to perform rapid rescue at the first time, greatly increasing the success rate of rescue. Cardiopulmonary resuscitation within 1 minute and AED defibrillation within 3 to 5 minutes can make the survival rate of patients with cardiac arrest reach 50% to 70%. (From Encyclopedia) Everyone might as well take a look at the usage method and collect memos. Hope this tragedy is less. That’s it.

High temperature + strenuous exercise, health problems should first be considered is that the environment temperature is too high, the body produces more heat, insufficient heat dissipation, and dehydration induced health problems. The human body weighs tens of kilograms, most of which are water. Metabolism continues to produce heat. Drinking a few mouthfuls of water with a temperature above 0 degrees Celsius has little effect on improving human body temperature and insufficient heat dissipation. The health risks caused by a person’s exercise in a high temperature environment for a few hours are greater than a few sips of water. Of course, letting people enter a low-temperature environment to quickly cool down is an important method to treat heat stroke. Ice water immersion is the preferred treatment. Including low-temperature rehydration, low-temperature enema and gastric lavage are also used in some cases. The most common cause of sudden death after exercise is heart disease. Hyperthermia itself is not good for heart health. The role of ice water in the whole disease process is limited. In daily life, ice water, as long as you are not uncomfortable in the process of drinking, you will not have any risks after drinking it, because the human body continues to metabolize, consume substances and produce heat, and it is easy to heat the ice water. The adverse events after drinking ice water can basically be attributed to other reasons that are not related to water temperature, such as unclean water, heat stroke, and so on.

There is no sign, a big living person says no, it’s all right. This is the inherent impression that many people have of sudden death. In fact, the population of sudden deaths is larger than we thought. In China, more than 500,000 people die every year due to sudden cardiac death alone. [1] Many people know that bad habits such as overwork, staying up all night for a long time, and disordered work and rest are the key causes of sudden death from overwork, but what everyone doesn’t know is that inappropriate participation in some sports events may also lead to sudden death! In fact, sudden deaths from sports are not uncommon in the field of sports. Statistics from the United States show that among the American people participating in sports, the probability of sudden sports deaths is about one in 250,000 each year, and non-athletes account for the majority. Most [2], including the American author (James Fix) of “Encyclopedia of Running”, also died of sudden sports death. Today, I will talk to you about the relationship between sports and life and health, hoping to help you exercise correctly and get a healthy body. Doesn’t it mean that life lies in exercise? How can you suddenly die because of exercise? During strenuous exercise, the body’s oxygen consumption increases and the heart’s work increases. If you sweat too much, the blood viscosity will increase and the blood supply of the myocardium will be insufficient. Acute myocardial infarction or even sudden death will easily occur. In addition, excessive movement during exercise may increase the risk of atherosclerotic plaque rupture and cause myocardial infarction. It should be noted that sudden changes in temperature and low temperature can easily aggravate the incidence of angina, myocardial infarction and sudden death. Generally speaking, the peak period of sudden death is from November to March of each year. However, in summer, when you are greedy for air conditioning, when the temperature difference between indoor and outdoor is large, it is also easy to cause heart disease. There is a sentence in “Yanzi Chunqiu·Miscellaneous No. 10”: “Oranges born in Huainan are oranges, born in Huaibei are oranges, leaves are similar, but in fact they taste different.” This sentence means that the environment has changed and things are different. The nature has also changed. Exercise is a good thing, but exercising at the wrong time and place is harmful to the body. For example, Gao Yixiang’s sudden death from exercise occurred outdoors in the early morning of winter. In this case, the human body’s metabolism should be in a low state. Our human body has a tendency to favor stability, maintaining a stable internal temperature and a stable blood pressure. And heart rate, and stabilize blood sugar. When you go outside for exercise in the cold winter, your body’s system (such as certain muscles, cardiovascular system, or other systems) will feel pressure, which will break the original balance and cause problems. Why is Gao Yixiang? He caught up in the most dangerous six hours! If the 24 hours a day is divided into four time periods, there will be a phase every 6 hours. In comparison, the 6 hours in the early morning (12 midnight to 6 am) are prone to sudden cardiac death and hypertensive crisis. [3] For the human body, the sympathetic nerves “work day” during the day and the vagus nerves “night work” at night, and the early morning is just the time when the two kinds of nerves are “handover”. At this time, the vagus nerve is exhausted after a night shift. The sympathetic nerves who are coming to take over are in a highly excited state. Sympathetic nerve excitement can cause rapid heartbeat, increased myocardial contractility, ectopic rhythm, etc., which may induce various arrhythmias, Brugada syndrome (a hereditary cardiomyopathy) and other cardiovascular events and even sudden death. In addition, studies have shown that inhalation of cold air below 0°C can easily induce coronary artery spasm. [4] So people with high blood pressure and cardiovascular patients should not go out for exercise in the cold winter morning and evening. “I don’t dare to exercise after reading this.” Don’t worry, you will know what to do if you continue to look down. First of all, don’t panic, to explain: in most cases, exercise is very good for the heart, especially for the heart of healthy people. Exercise can make our myocardium more developed, better oxygen-carrying capacity, so that our heart cells grow healthier and can maintain a better heart rhythm. But this is also within a certain limit. If your exercise volume is particularly large, it will affect the rhythm conduction of heart cells, and even problems such as arrhythmia, so moderate exercise is enough. To avoid sudden sports death, you need to know these to avoid sudden sports death. You need to know these: 1. Exercise does not warm up, it is better not to exercise. Competitive sports are sports that require high physical standards, so preparations before exercise must be very adequate. , The most basic warm-up requirement is that the body should sweat slightly, and the heart rate should be increased by 20 to 30 times per minute or even higher than usual. The stretching of ligaments and the movement of joints are also indispensable. In daily fitness, we can do some simple warm-ups: (1) Stretching “stretching” can increase the elasticity and flexibility of muscles and tendons, and can also increase the range of joint activities. (2) Let the body heat up and do some high-leg raises, trotting in place, etc. to make the body sweat slightly. (3) Adjust your mental state and focus your attention to get yourself excited. 2. Pick a “good day and auspicious day” to take the most popular running sport as an example: (1) If time permits, try to run from 4 to 6 in the afternoon. (2) If you choose to run in the morning, please choose to start running after sunrise, remember to add a little sugar before, such as a cup of honey water. (3) Choose night runners, try to finish exercise before 11 o’clock in the evening, leave enough time for bathing and rest, and avoid being too excited before going to bed, resulting in poor sleep quality. In addition, I would like to remind everyone: It’s not that you can have a good rest during the day, and you can play sports in the cold outdoors at night. 3. “Human potential is unlimited!” “No, you are limited.” The meaning of this sentence is to remind everyone that you must pay attention to the intensity of exercise when exercising. Now the international consensus is to do it every week. For more than 75 minutes of moderate-intensity exercise, what kind of exercise intensity is considered moderate? For example: jogging, going up the stairs, riding a bike on a slope, skating for about 10 minutes can reach the level of moderate exercise. But there are no absolutes. For example, patients with cardiovascular and cerebrovascular diseases cannot exercise according to this reference time. For ordinary people in good health, if they are engaged in sports such as jogging, swimming, etc., it is perfectly possible to exercise for about half an hour a day; but if they are engaged in sports of moderate intensity or higher, they may exercise more than twice a week. Three times is more appropriate, such as playing football. The internationally accepted view is that professional athletes can play two full official games a week. There are many types of exercises, but no matter what kind of exercise you are participating in, you must abide by a big principle, that is, normal exercise intensity is not to make the body excessively fatigued, and not to allow the body to experience obvious pain or even joint swelling during exercise. 4. I also want to say to the fitness professionals who spend many years in the gym: vigorously may work miracles, but more likely to go wrong! Many sports have high requirements for participants. Even fitness enthusiasts who are full of tendons are at risk of injury when participating in competitive sports. The so-called good travellers, the outpatient department of sports medicine, the most visited are fitness enthusiasts who are physically strong. Let’s take an example: Many people say how many kilograms they bench press in the gym, and their physical fitness is comparable to professional athletes. But I want to say that strength alone is useless, even if you say “I am strong, I will go to the head office of weightlifting”, but the technical content of the competitive sport of weightlifting is actually very high, and it can be called a high-risk sport. For example, the way you use your strength, the skill of the movement, the maintenance of your body shape while doing the movement, etc., all of which require accumulated training. If a strong fitness enthusiast blindly lifts weights, it is prone to sports injuries. Finally, I want to emphasize to everyone: scientific and reasonable exercise is good and harmless to our health! Don’t think of sudden cardiac death when you mention exercise, because many studies have shown that exercising in daily life is good for the heart. So, rest assured and boldly go for sports!

It can be basically determined to be sudden cardiac death. Sudden death after strenuous exercise and drinking cold drinks is actually not uncommon, and you can find a lot of them with just a search. The cause of death is basically cardiac arrest, that is, sudden cardiac death, and strenuous exercise and cold drinks are all triggers. Therefore, it is wrong to say that it has nothing to do with cold drinks and is caused by cold drinks. To be correct, cold drinks are related to sudden death, but the relationship is not directly causal, and the underlying heart disease of the sudden death is the root cause. So there is no need to demonize cold drinks, otherwise so many people drink cold drinks after strenuous exercise but nothing can be explained. In fact, this situation has also been reported. Cold drinks can cause irritation to the body, and the cardiovascular effect is to cause the vagus nerve reflex to slow down the heart rate and constrict blood vessels. If there is a heart disease, the slower heart rate caused by cold drinks may induce fatal arrhythmia, and eventually lead to sudden cardiac death. As for strenuous exercise at high temperatures, it is also a factor that induces heart disease, which is also an inducement. Strenuous exercise itself can easily lead to sudden death of athletes with underlying heart disease, such as congenital heart defects, hypertrophic cardiomyopathy, coronary artery disease, and myocarditis, but it is not clear to me. According to statistics, nearly 80% of sudden deaths after exercise are related to cardiovascular disease, and these sudden deaths are common after strenuous exercise mainly in basketball and football. Strenuous exercise will increase the burden on the heart, forcing the heart’s engine to do more work than usual to meet the body’s needs, and some of the’engines’ that have some problems in themselves are prone to lack of power and induce their own acute myocardial infarction and malignant heart rhythm. Disorders, and eventually lead to sudden death. It is worth noting that regular and moderate exercise can reduce this risk, and the risk of sudden death from sudden strenuous exercise for people who don’t usually exercise can be dozens of times higher than that of regular exercisers. The increase in outside temperature can also cause abnormalities in the heart, which some people have mentioned before will not talk about it. To minimize this risk, you need a scientific exercise plan: 1. Check your physical condition, choose a moderate-intensity exercise method, don’t choose the strongest one when you come up; 2. Start regular exercise with low-intensity exercise. Avoid starting strenuous exercise at once when you are not exercising. Do 10-30 minutes of low-to-medium-intensity exercise before strenuous exercise, such as running; 3. Avoid outdoor exercise in extreme weather, and try to drink warm water after exercise to reduce physical stimulation .

In the past, my dad came home sweating from work outside in the summer. The first thing to do was drink cold water and take a bath. My mother said, “Can’t take a bath until it cools down? Imagine for yourself, what would happen if a piece of hot coals were watered suddenly? It was extinguished all at once, and it was the same for people, so hot. When the weather is very hot, the whole person is in hot sun and sweat. At this time, drinking cold water and taking a cold shower. What is the difference between pouring charcoal, and people have to put it out!” My mother is not well-educated, and she can’t say anything about it. Professional principles, but I think the analogy she used is very appropriate. People might say that every time I get tired from work or exercise, I just drink water and take a shower when I go home. I don’t see anything wrong. The same goes for others. Sudden death will either not happen, but once it happens, it will be the only time. Everyone’s physical condition is different, and the consequences of doing the same thing are different. Do you think sudden death is an accident? No, sudden death only happens suddenly, it is caused by disease. Especially now that I enter the dog days in July, it is really not suitable for high-intensity exercise. Boys’ love of basketball is understandable, but they can choose indoor basketball courts and control the playing time, and take more breaks in the midfield. Do not sit down and drink a lot of cold drinks immediately after strenuous exercise. You can walk around slowly when you are finished and rest. When you are relieved, drink two sips of water to moisten your throat and drink slowly. After returning home, sit quietly and wait until I feel “cold” completely before going to take a bath. It should also be noted here that after strenuous exercise, do not face the fan where the “high wind blows”. Blowing for a long time will cause muscle tension in the face, and severely cause facial paralysis. Especially when I was blowing and falling asleep, I forgot to turn off the fan and kept blowing to my face for several hours or even longer. In the face of accidents and diseases, we are all weak. However, in fact, as long as we guard the line of defense, we will not be easily breached. Hey! Frequent news of sudden deaths still failed to allow some high-risk groups to consciously avoid risks. I still remember a hot search about myocardial ischemia and sudden death in April. My dad once said about myocardial ischemia and sudden death and other preventive measures. After all, if the stick doesn’t hit one’s body, it doesn’t know that it hurts. There are still too many people who have survivor deviations. It has happened, which can only be regretted. It also reminds us that we must pay attention to our own health, and we must take precautions and safeguards in our daily lives. There are two diseases mentioned in the news description. One is myocardial ischemia and the other is sudden death. Is there a necessary connection between the two? Is myocardial ischemia severe, how can it be caused, and how can it be prevented? How did sudden death happen? Dad made an inquiry about relevant information and came up with the following information. Perhaps after reading it, everyone will be able to understand the occurrence and prevention of these diseases. 01 What is myocardial ischemia? Even if your body is good on weekdays, you should have regular physical examinations. If you have been advised by your doctor to be hospitalized, you should listen to the doctor’s advice. Don’t always think that doctors are bluffing people, just want to charge more patients and pay more. Once people are admitted, they will be responsible for them. Doctors more than anyone hope that patients are not seriously ill and that they can recover and be discharged from the hospital. In simple terms, myocardial ischemia is a pathological condition in which the blood flow to the heart is reduced, leading to insufficient supply of the heart, which causes abnormalities in myocardial energy metabolism and the heart cannot work normally. There are many reasons for myocardial ischemia, such as coronary artery obstruction and lowered blood pressure. The high-risk factors that cause these reasons are usually less exercise, smoking, obesity, etc., and another factor that is easier to cause is advanced age. Therefore, we often hear of angina pectoris and myocardial infarction in the elderly. These are most likely caused by myocardial ischemia. Angina pectoris and myocardial infarction are all serious symptoms. There are some early symptoms of myocardial ischemia that we need to be alert to. 1. I feel chest tightness and shortness of breath during activities, but a short rest can relieve it 2. During sleep, especially when the pillow is low, I suddenly feel palpitations, breathing difficulties, suffocation or suffocation, and I need to sit/stand up to relieve it; 3. Feeling tired and lack of energy for no reason, toothache, exercise-related sore throat/tightness, cervical pain, etc. may also occur; 4. Chest pain, chest tightness, etc. after eating or drinking in cold weather; 5. When tired There will be dull or severe pain in the heart, the pain can radiate to the shoulder, and it can be relieved by a short rest after a few minutes; 6. Sudden bradycardia; it is a sudden drop in blood pressure, slow heartbeat, and may faint. In fact, with a little attention to these situations, you can find problems in time. If there are any of the above situations, especially friends who appear frequently. Be sure to go to the hospital for examination and treatment in time to prevent sudden death and angina. Don’t think that myocardial ischemia will only cause occasional heart discomfort. It will be relieved every time you take a break, so there is no need for treatment. If it is worth thinking about it this way, you may have to consider another question, which is whether the current savings are enough: Is it enough for the treatment costs after a sudden fall? Is it enough that when you can no longer bear financial responsibilities for your family, your family’s life will not fall into trouble? If it is the stage of myocardial ischemia and the condition is stable, the annual drug cost is about 10,000 to 10,000; the cost of intervention depends on whether or not the stent needs to be implanted, the number of stents is different, the operation cost is about 4,000 yuan; The stent is about 10,000 to 10,000 yuan, and the balloon/guide wire costs about 4,000 to 5,000 yuan; if it is not treated in time, coronary atherosclerosis will occur, and coronary bypass surgery is required, and the cost is about 60,000 to 80,000 yuan. The above are only expenditures when the condition is not serious. If sudden death, myocardial infarction, angina pectoris, ischemic cardiomyopathy, etc. occur, and the high cost of life is required for treatment, the most feared is that there is no chance of continuous treatment. It left the family in grief. Therefore, if you continue to be unable to cope with these risks, dad still recommends to pay attention to your health and do the following: 1. Pay attention to your diet, low salt and fat, and eat more vegetables such as sweet potatoes, carrots, black fungus, etc. Drink green tea instead; tea contains theophylline, which is a diuretic, which is helpful for the treatment of myocardial ischemia. It also contains vitamin C to prevent arteriosclerosis, but do not drink strong tea. 2. Good living habits, don’t be overjoyed, don’t stay up late, get enough sleep, don’t watch horror movies before going to bed, quit smoking and alcohol, avoid strenuous exercise and exercise after a meal; 3. Exercise appropriately, even if the heart is abnormal. Exercise vigorously, but do some gentle stretching exercises according to your ability; 4. Pay attention to the establishment of a security system, such as social security, insurance (medical insurance, life insurance, etc.), etc., according to your own situation, and reduce the burden of expenses; 5. Regular inspections , Pay close attention to changes in the situation, especially those with three highs, obese people, diabetic patients, and people with a family history of cardiovascular disease. The electrocardiogram is the most commonly used non-invasive examination. The type of electrocardiogram change of myocardial ischemia depends on the severity, duration and location of ischemia. As mentioned above, myocardial ischemia may cause sudden death, so how does sudden death happen? In addition to myocardial ischemia, what other high-risk factors are there? Dad took everyone to learn about some situations about sudden death. 02 How does sudden death happen? First of all, my dad should make it clear to everyone that sudden death is not an accident, it is a serious disease. The World Health Organization defines it as: “Patients who are normally healthy or seemingly healthy, in an unexpectedly short period of time, die suddenly due to natural diseases are sudden death.” The simple summary is “Sudden death due to illness, so it is just sudden death. Usually things happen suddenly, much like accidents. Sudden death has the following characteristics: 1. Its suddenness, urgency, severity, degree of malignancy and consequences are not comparable to other diseases, and it can be called the first disease; 2. Sudden onset 3. The incidence rate is high. The number of sudden deaths in China exceeds 500,000 every year, and an average of more than 1,000 sudden deaths occur every day. 4. Most of the sudden deaths occur outside the hospital, and 87.7% of the sudden deaths occur outside the hospital in China. Sudden deaths are divided into sudden cardiac deaths. And non-cardiac sudden death, of which coronary heart disease accounts for more than 90% of all sudden cardiac deaths; why is myocardial ischemia prone to sudden death? High-risk factors lead to coronary atherosclerosis, coronary atherosclerosis leads to myocardial ischemia , Myocardial ischemia leads to sudden death. The coronary heart disease in sudden death from coronary heart disease mentioned above is related to atherosclerosis. These factors are intertwined with cause and effect, so in the final analysis, the prevention of sudden death still needs to avoid high-risk factors. Daily prevention methods It is similar to the method of preventing myocardial ischemia, the main ones are: healthy diet, regular work and rest and proper exercise, etc. Here, my dad would like to focus on the four lines of defense to prevent sudden cardiac death. , Sudden cardiac death will not happen. In daily life, we must pay attention to avoiding root-line factors, and at the same time, we must be fully prepared, especially those engaged in high-intensity work. It is particularly important to build our own security system and be responsible for ourselves. I am also responsible to my family. Write at the end: I am Bao Jialin, my dad, a professional insurance evaluation agency.

Written at the forefront: 1. This question is about drinking cold water “after strenuous exercise”. All the statements in this answer that involve drinking cold water are also talking about “drinking cold water after strenuous exercise”. 2. The chest anatomy is so, whether the cold water in the esophagus can affect the heart to see for yourself, it is not responsible for explaining. Original answer: According to the old man: In the past, on the barley farm, if a thirsty and hot pedestrian came to ask for water, he would grab a handful of wheat husk in the scoop. People have to blow the wheat husk to drink water, so that it will not hurt the body quickly. The above is just to tell a heart-warming story, and the following is the business: after drinking ice water, it will first cause cold stimulation to the heart, which will increase the heart rate and increase the oxygen consumption. May induce arrhythmia and myocardial ischemia. Secondly, the water entering the digestive tract is quickly absorbed, and a lot of electrolytes will be lost when sweating just after exercise, the blood will be diluted, and the electrolytes may also be imbalanced, which further increases the burden on the heart. Finally, blood is mainly supplied to the limbs after exercise, and the blood supply to the digestive tract is inherently small. Another cold stimulus makes the blood supply more tense, which may also cause abdominal discomfort and even more serious digestive tract diseases. But returning to this question, it can only be said that cold water may be one of the triggers of sudden death. As for the specific cause of sudden death, it is likely to be the underlying cardiovascular disease. To be sure, it is still necessary to wait for the result of autopsy.

The reporter was still bald, and when he heard the ice water, he was anxious to press the article to grab the heat. Don’t ask if the ice water is a drink, whether you play computer games, listen to some corrupt pop music, and don’t ask you why you should indulge in Western sports like basketball instead of Tai Chi square dance to keep fit. . That much educational meaning was wasted in vain.
