“Li, build the beginning also. Winter, the end, the collection of all things.” Lidong, the 19th of the 24 solar terms, indicates the beginning of winter. After winter, the sky is obviously darker earlier, and it is more important to prevent cold and keep warm. Winter is coming, cardiovascular disease is high: after winter, the temperature plummets, some parts of the body are very sensitive to the cold, should pay special attention to keep warm. People with cardiovascular disease, especially to protect the head, hands, feet; go out wearing gloves, hats, scarves, wearing coats; before going to bed with hot water to soak your feet; when the wind is blowing the best not to walk into the wind. Winter temperatures gradually lower, so that the human body vasoconstriction, easy to lead to blood flow obstruction, vascular obstruction, thus inducing cardiovascular disease attacks and recurrence, such as myocardial infarction, the more extreme de consequences can lead to “sudden death”. The general public, especially the middle-aged and elderly friends must be actively prevented. The reason why winter has become a “hotbed” of cardiovascular disease, mainly for the following reasons: First: the cold weather At low temperatures, blood vessels will contract, resulting in ischemia and hypoxia of important organs, inducing cardiovascular and cerebral vascular disease; at the same time, if insufficient hydration, but also prone to cause blood viscosity, triggering thrombosis and other disorders. The temperature difference between day and night causes the human body for day and night changes in heat and cold is not easy to adapt to, the nervous system, the endocrine system is prone to dysfunction, may induce acute diseases. Second: dry climate The dryness of the mouth, nose and other parts of the mouth is very easy for bacteria to invade the channel, and the weakening of the respiratory cilia function, also makes it difficult to discharge germs, increasing the incidence of morbidity. Third: cholesterol Hypercholesterolemia is only one step away from coronary heart disease, cholesterol levels are also seasonal changes, winter cholesterol levels are the highest, the lowest in summer. Sympathetic nerve activity increases in winter, and the level of blood pressure-raising hormones rises, leading to higher and more fluctuating blood pressure, which is more pronounced in the elderly. Fourth: “cat winter” habit This habit makes many people in the winter sedentary, poor indoor ventilation in winter, the room humidity is not easy to control, coupled with the lack of heating facilities in most southern families, low indoor temperature, resulting in poor blood circulation, the human metabolism is disorganized, prone to cardiovascular and other diseases. After winter, a significant drop in temperature, air pollution, infectious diseases and changes in physiological functions of the body and lead to a high incidence of the following cardiovascular and cerebrovascular diseases: (1) hypertension; (2) myocardial infarction and angina pectoris; (3) atrial fibrillation and ventricular arrhythmia, etc.; (4) ischemic stroke and cerebral hemorrhage; (5) aortic coarctation; (6) venous thrombosis of the lower extremities and pulmonary embolism. Among them, myocardial infarction, pulmonary embolism, stroke and aortic coarctation and other critical illnesses caused by the incidence of sudden death will greatly increase. Safe winter, pay attention to the following points: 1, standardize the use of medication People with cardiovascular disease should be on time, standardize the use of medication, and according to climate change, under the guidance of a doctor to adjust the drug, control the recurrence of various chronic diseases, especially to control blood pressure. 2, pay attention to warm blood vessels, especially the coronary arteries in winter cold, easy to contract, spasm, blood supply shortage, and may lead to embolism. 3, appropriate exercise to reasonably arrange the exercise time and control the amount of exercise, the elderly do not rush out of bed when they wake up, first lie in bed for a while. Cardiovascular disease patients should not exercise in the morning, exercise should be different from person to person, according to ability. Early in the morning, the human blood vessel strain is the worst, is the peak time of acute infarction, winter to wait for the sun to rise up and then go to exercise, at this time, the temperature rises, can avoid the body suddenly by the cold stimulation and the onset of the disease. 4, reasonable diet low-salt low-fat diet, adult daily salt intake per person should be less than 6 grams, more food containing dietary fiber adequate food. A large number of tonic hot food and tonic wine, it is easy to cause increased blood fat, induced cardiovascular disease, so winter tonic must be based on the individual’s constitution. Winter climate is dry, get up early or before going to bed, it is best to drink a cup of warm water, which is conducive to dilute blood, but also can prevent constipation. 5, the balance of mind Emotional excitement is a taboo of cardiovascular disease, cardiovascular disease patients in particular to relax the chest do not let the emotional ups and downs too much.
