1, mood swings, depression and anxiety: impatience, depression and anxiety accelerate the formation of cardiovascular disease, is an independent threat factor of cardiovascular disease, especially myocardial infarction. Cardiovascular disease accompanied by anxiety and depression becomes an important factor of sudden death. 2, snoring during sleep: snoring is a sign of sleep apnea syndrome, if the “sleep apnea” time more than 120 seconds at a time, it is likely that sudden death in sleep. 3, overwork: fatigue and the impact of rest will make people’s sympathetic and parasympathetic nerves in a dysfunctional state; irregular meals and rest will cause low sugar and low potassium, electrolyte disorders, resulting in cardiac arrhythmia, which is an important cause of sudden cardiac death. 4, long-term stay up late: long-term stay up late induced arrhythmia, premature heartbeat and sudden fainting, if not get timely first aid, prone to sudden death. In addition, long-term late night will form thrombosis, blocking blood vessels. 5, work life stress: will lead to hypertension, coronary heart disease, etc., 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 accounted for the whole. And fat people are prone to congestive heart failure, combined with coronary heart disease is prone to myocardial infarction and sudden death. 7, sedentary in front of the computer: long-term Internet access is a static action, the blood viscosity is high, the lower limbs may form deep vein thrombosis, the movement of the thrombus off, may cause pulmonary infarction, serious may lead to sudden death. 8, smoking and drinking: the risk of myocardial infarction in people who smoke is three times higher than in ordinary people. Exactly what can make the heart rate increase, blood pressure rise, is to pull the trigger on a heart attack, long-term alcohol consumption can also lead to heart failure and other diseases.
