Cold winter is a time of high incidence of cardiovascular diseases. Every cold season, the incidence of coronary angina and myocardial infarction will increase significantly. In the cold winter, if the patient is not properly protected and causes a cold, the condition will be aggravated or angina pectoris will be induced. The reason why coronary heart disease is highly prevalent in winter is because the cardiovascular system is sensitive to changes in temperature. Mainly because, the winter temperature drop, easy to make the body sympathetic nerve excitation, prompting the blood pressure increases, heart rate continues to accelerate, thereby increasing myocardial oxygen consumption, cold weather and cause the spasm of the body surface of the small blood vessels and contraction, so that the blood flow rate is slow, the blood viscosity is also significantly higher, aggravating the burden on the heart, at this time, myocardial hypoxia aggravated, there is chest tightness, angina pectoris, easily induced myocardial infarction. Moreover, the cold weather in winter makes people’s exercise is reduced, thus reducing the emission of sweat, thus causing the body’s lipid intake and metabolism ratio is imbalanced, blood viscosity increases, easy to form blood clots and thus induced myocardial infarction. In addition, winter is a period of high incidence of respiratory diseases, such as upper respiratory tract infections, pneumonia, etc., which can aggravate the condition of patients with coronary heart disease. How to prevent the occurrence of coronary heart disease by health care in winter? 1, coronary heart disease patients in the cold winter, must pay attention to the cold warmth, especially the face and limbs of the warmth. You should avoid going out when the temperature is low so as not to be stimulated by cold air. However, in order to strengthen the resistance of the body, some outdoor activities should be carried out appropriately when the weather is good. In addition, you should pay attention to the circulation of air in the room, if the room is not ventilated for a long time, it will lead to lack of oxygen in the room, which is very easy to induce coronary heart disease, and this is not conducive to the prevention of colds and upper respiratory tract infections. 2, the patient in winter should pay attention to keep warm to avoid the cold, go to bed early and get up late, reduce the time of outdoor activities, to avoid exercise in the cold, wind, snow, you can choose the method of indoor fitness. In addition, should avoid fatigue, nervousness, emotional excitement, timely adjustment of their own state of mind, to maintain a happy mind, optimistic and cheerful good mood, the coronary heart patients is essential. 3, moxibustion health coronary heart disease, angina pectoris, Chinese medicine called thoracic paralysis, most of which is due to the lack of heart yang, resulting in stagnation of blood, water stagnation and cold condensation, the heart veins do not pass before the appearance of pain, stuffiness and other symptoms. Speaking of heart yang, we must first talk about yang qi, yang qi is an important concept in traditional Chinese medicine, figuratively speaking, yang qi is like a steam engine in the fire, only the fire is strong, can make the water into water vapor, and then promote the normal operation of the steam engine. If the fire is not enough, the body’s gas, blood, water and other substances, can not be normal gasification, stop gathering body localization, can not complete the normal work, and then a series of decline in vitality. Methods: Moxibustion Guanyuan, Ashigaru, Tanzhong, Zhiyang, 10 minutes per point. Guanyuan point is in the abdomen, four horizontal fingers below the navel. The foot Sanli is on the outside of the calf, four horizontal fingers below the knee and one horizontal finger from the anterior tibial ridge (the highest line of bone in the front of the calf). Tanzhong is in the center of the chest, between the two nipples. Zhiyang in the back, the lower corner of the shoulder blade line in the center. Specific operation, with moxa ignited, 2-3 centimeters from the acupuncture point on the cyclopean moxibustion, each point about 10 minutes, four points (foot Sanli choose a side of the acupuncture point) a total of 40 minutes of moxibustion, once a day.
