INTRODUCTION “Trade your life for money before 40, buy your life with money after 40.” This popular joke among white-collar workers in China has gradually become a reality and applies to all walks of life. Statistics from 2013 show that the number of people who die from overwork in China has reached 600,000 per year, surpassing Japan as the number one country in terms of overwork deaths. This means that about 1,600 people die every day from diseases caused by overwork. The majority of people are like a wind-up machine, working hard to make ends meet. Police: On the evening of October 31, 2016, Zhang Jinbo, a civilian police officer in Liaoning province, died suddenly at work at the age of 23 years. Internet: at 3:00 a.m. on October 6, 2016, Zhang Rui, founder of Dr. Chunyu, died of myocardial infarction due to overwork at the age of 44 years. Media: at around 19:40 on June 29, 2016, Jin Bo, deputy editor-in-chief of the Tianya community, suddenly fainted on the platform of Beijing Subway Line 6 at Hujialou Station in the direction of Lucheng, and then lost consciousness at the age of 34 years old. Students: in the morning of November 10, 2015, Nanyang City, thirteen middle school ninth grade twelve students Yun Bo, due to cardiac arrest suddenly fainted in the morning self-study classroom, to be 120 emergency vehicles arrived when there are no vital signs, at the age of 15 years old. It is reported that Yun Bo the first night to write homework to write more than 12 o’clock, the day of the incident 6:20 in the morning to get up. …… I. “Sudden death” is a word you must understand 1. 500,000 people die suddenly from cardiac causes in China every year, while the success rate of resuscitation is less than 1 percent. 2. Sudden death is more and more likely to occur in young people. 3. 3. excessive fatigue easily triggered chronic fatigue syndrome, the human body manifests itself in the body metabolic disorders, nervous system dysfunction, immune system decline, and in severe cases may even die suddenly. Second, easy to sudden death crowd 1, depression: depression and anxiety to accelerate the formation of cardiovascular disease, cardiovascular disease, especially myocardial infarction is an independent threat factors. Cardiovascular disease accompanied by anxiety and depression, an important factor in sudden death. 2, snoring: snoring sleep apnea syndrome is a sign, if the “sleep apnea” time more than 120 seconds at a time, it is likely to occur in the sleep of sudden death 3, overwork: often stay up all night will make the sympathetic and parasympathetic nerves in a dysfunctional state; eating, rest and relaxation irregularities will cause low glucose and low potassium, electrolyte disorders, resulting in cardiovascular disease and cardiovascular disease. Electrolyte disorders, resulting in arrhythmia, which is an important cause of sudden cardiac death. 4, stay up late: long-term stay up late induced arrhythmia, premature heartbeat and suddenly fainted, if you do not get timely first aid, easy to sudden death. In addition, staying up late for a long time will form blood clots and block blood vessels. 5, life stress: will lead to hypertension, coronary heart disease, and will increase the risk of arrhythmia, vascular spasm, and even induce sudden death. 6, obesity: cardiovascular disease loves fat people. Obese people almost all the cardiovascular disease risk factors account for all. And fat people are prone to congestive heart failure, combined with coronary heart disease is prone to myocardial infarction and sudden death. 7, sedentary computer: long-term Internet belongs to the static action, blood viscosity is higher, the lower extremities may form deep vein thrombosis, movement of thrombus dislodgement, may cause pulmonary infarction, may lead to serious sudden death. 8, smoking and drinking: the risk of myocardial infarction in smokers is three times that of normal people. What exactly can make the heart rate faster, higher blood pressure, is to pull the trigger of a heart attack, long-term alcohol consumption can also lead to heart failure and other diseases. Third, there are signs before the onset of sudden death 1, pain In comparison, the pain response is the onset of sudden death signs, the most easily perceived signals. When you feel intense, tight, crushing pain in the chest, and feel breathless, we must be vigilant. 2, potential causes In addition to pain, but also be alert to potential causes that may lead to sudden death. For example, whether there is a history of thrombosis. For example, a patient with a fracture who has been restricted from exercise for a period of time is susceptible to venous thrombosis, and once a venous thrombus falls out, a pulmonary infarction may occur. 3.Breath-holding, obvious cyanosis, purple lips, blood oxygen drop If the nature of the work is sedentary or standing for a long time, the blood circulation is not good, when the disease attack, in addition to pain, if there is breath-holding, obvious cyanosis, purple lips, blood oxygen drop, etc., we should be highly suspicious of the possibility of pulmonary embolism. 4, severe elevation of blood pressure For patients with aortic coarctation, the onset of signs of severe pain, and pain will be accompanied by severe elevation of blood pressure. 5.Chest pain Coronary heart disease has the highest rate of sudden death. Typical coronary heart disease manifestation is chest pain, usually occurs in the sternum behind, the whole border is not very clear, it will be appropriate to the area a little bit larger (with the palm of the hand area is almost the same), or can not say exactly where the pain, mainly the feeling of boring pain. And the sting of a needle or “press the pain” feeling is often not related to the heart. Fourth, from fatigue to overworked death is only 5 steps 1, do not get up the spirit of this stage of the people often feel less than the previous so full of energy. At this time, the amount of oxygen inhaled by the body is reduced, and the concentration of oxygen in the blood and blood glucose value decreased. So the body sends out an alert, telling you “I have been fatigued”. To eliminate this fatigue is very simple, 5 times a day deep breathing can be, can improve lung capacity, increase brain oxygen supply, relieve fatigue. When inhaling, first make the abdomen expand, and then make the chest expand, after reaching the limit, hold the breath for a few seconds, and gradually exhale the gas. When exhaling, first contract the chest, then the abdomen, and try to expel the gas in the lungs. Repeatedly inhale and exhale for 3 to 5 minutes each time. In addition, you can also take in a small amount of sweet food to quickly replenish physical energy. 2, lethargy At this stage, people not only have no energy, but also the whole person is lethargic, and even inexplicably frustrated. At this time, the concentration of oxygen in the human blood and blood sugar continues to decline, resulting in muscle or visceral tissues into the plight of oxygen and nutritional deficiencies. In addition to deep breathing, you need to do some light gymnastics every day, such as tai chi, so that the stiff parts of the body can get stretched and normal blood flow can be restored. You can also do the chest expansion exercise in the radio exercise, adhere to 10 to 20 minutes to be effective. In addition, it is best to take a hot bath after work, and insist on morning exercise to restore vitality. 3, body aches and pains At this time, people will feel physically exhausted, unwilling to get up in the morning, shoulders, back, waist, etc. are always sore and tired, dull skin, thin or obese, agitated and irritable, some people will also have diarrhea, hypothermia, sleep grinding teeth. At this time is the last barrier against the disease on the body, pay attention to keep warm, sleep enough 8 hours a day, do not go to bed before strenuous exercise, in order to improve the quality of sleep. If conditions permit, it is best to take a week’s vacation. People who rely on coffee, strong tea, drugs to change these habits, so as not to put the body into a vicious cycle. 4, began to get sick In addition to pain in the body, there will be acne, mouth ulcers, periodontal disease, gastritis, constipation and loss of appetite and other symptoms, and even mild depression. People in this stage should go to the hospital in time for medical checkups to solve existing health problems and catch diseases that have not yet “sprouted”. Every day should have enough sleep, exercise, at least adhere to more than 1 week, so that the body to restore the original pace. If you are depressed, do not abuse drugs, you can find friends to chat, participate in group activities and other ways to regulate, if you can not self-regulation can seek medical help. 5, cancer latent Rest and exercise is the key to eliminate fatigue. When resting, you should take the opposite posture to that of work, for example, if you are mostly standing at work, you should sit or lie down when resting; if you are always working at your desk, you should stand up when resting and raise your arms to loosen your shoulder muscles. In addition, in addition to adhering to the daily exercise, but also targeted exercise, where feel stiff, cold, focus on exercise where.
