The winter solstice is the time when yin energy is in full bloom and yang energy begins to sprout, it is significant to focus on the prevention of cardiovascular diseases at this time. At the winter solstice, the temperature continues to drop and enters the peak period of cardiovascular disease attacks, as the disease is caused by lesions of the blood, its damage to the human body is insidious, gradual and systemic, and there are no obvious clinical symptoms at the beginning, thus it is called The “silent disease”, yet it is the number one killer of human health. Patients with such diseases should pay more attention to strengthen self-care and prevention, and prevention is better than cure. Cardiovascular disease is a serious threat to human beings, especially the health of middle-aged and elderly people over 50 years old common disease, even if the application of the most advanced and perfect treatment means, there can still be more than 50% of the survivors of cerebrovascular accidents can not completely take care of their own lives! The number of people who die from cardiovascular and cerebrovascular diseases in China is as high as 3 million each year, ranking first among all causes of death. Our folk have the habit of winter tonic, especially the winter solstice, with the change of people’s dietary structure and habits, people like to eat some high protein, high fat, high calorie tonic, but this is very unfavorable to hypertension, coronary heart disease, stroke patients, prone to high blood viscosity, high blood fat, high cholesterol, accelerating the process of atherosclerosis. Atherosclerosis is also the basis for the development of hypertension, coronary heart disease, acute myocardial infarction, stroke and other ischemic cerebrovascular diseases. So what is atherosclerosis? As the name implies, it is a hard mass with the appearance of thick porridge attached to the inner wall of arteries. These hard lumps can block blood vessels and lead to poor blood flow. Atherosclerosis is caused by contaminated blood, increased blood viscosity and consequently increased blood lipids (cholesterol and triglycerides), resulting in the deposition of large amounts of lipids in the blood vessels, which are deposited on the vessel walls, narrowing the lumen and thickening the walls, and finally forming atherosclerotic plaques. In winter, the temperature gradually decreases, the human metabolism is slow, and the low-temperature stimulation easily makes the human sympathetic nerve excitation, prompting the blood pressure to increase, the heart rate continues to accelerate, thus increasing the myocardial oxygen consumption. The cold weather also causes sudden vasoconstriction, which can easily lead to vascular blockage, interruption of blood supply, obstruction of blood flow, so that the toxic substances in the blood vessels are not easily discharged, thus triggering the onset and recurrence of cardiovascular and cerebrovascular diseases. It is the “eventful time” for cardiovascular and cerebrovascular patients. In particular, the winter solstice is the month of the year when sudden cardiovascular deaths peak. Because of the sudden cold, blood pressure will suddenly rise, so that the original hardened and fragile small arteries can not withstand the strong internal pressure and be “detonated”, cerebral hemorrhage; because of the first cold, so that the blood is too thick to self-regulate, the blood will be in the rough, small arteries in the slow flow, easy to form small thrombus, resulting in cerebrovascular blockage or myocardial infarction. Prevention of cardiovascular disease in winter should pay attention to the following aspects: life pattern: the morning temperature is low, not suitable for morning exercise. Middle-aged and elderly people had better exercise after breakfast 9-10 o’clock, more sunshine can promote calcium synthesis and absorption. Moderate exercise: to exercise according to the physical and mental conditions, aerobic exercise every day for not less than 30 minutes, do not choose climbing, running, playing ball and other strenuous sports projects. Maintain an optimistic attitude: avoid emotional ups and downs. Studies show that the heart and blood vessels are most sensitive to emotional reactions. Pay attention to diet: eat more soy products. Soybeans are rich in a variety of phospholipids necessary for the human body, and regular consumption of tofu, bean sprouts, dried bean curd, soybean oil and other soybean products can prevent cardiovascular disease. Regular checkups: Patients with cardiovascular diseases should have regular reviews of blood pressure, blood sugar, blood lipids and electrocardiogram and other related items. Drug prevention: Patients with cardiovascular and cerebrovascular diseases should take Chinese herbal medicine golden dendrobium, which has the function of improving blood vessel wall, inhibiting platelet aggregation and adhesion and reducing blood viscosity, under the guidance of doctors to increase blood flow rate and prevent thrombus formation.
