At present, influenza A has been alleviated under the active control of the municipal government, but we still need to go to public places less often, wash our hands and ventilate more often, and we should not take it lightly in our minds so as to reduce the occurrence of influenza A and other respiratory diseases. In addition, coronary heart disease, hypertension and other cardiovascular and cerebrovascular diseases, as well as other types of respiratory disease clusters are also on the rise, adding a lot of pain and burden to people’s bodies, minds and families. Therefore, how to prevent these diseases is particularly important. First of all, you should keep warm and take your medication on time. Listen to the weather forecast in time, refer to the dressing index, not to lose a good guide to avoid the cold to reduce the resistance of the respiratory mucosa, as well as cause the blood vessels by cold contraction, blood pressure increases, thus increasing the burden on the heart, especially the coronary arteries by the cold is more likely to contraction, spasm, the occurrence of insufficient blood supply. So pay close attention to keep warm, after the snow, especially when the snow temperature is lower, the road is slippery some ground is wearing armor ice, so try to reduce travel to avoid illness and fall; at the same time chronic hypertension patients may also have to add drugs to avoid vasoconstriction caused by hypertension drugs “failure”, poor blood pressure control and cause acute coronary events occur. Secondly, drink more water, diligent ventilation. Dry air in winter can easily damage the mucous membrane epithelial cells of the respiratory tract, leading to local upper respiratory tract infections, especially in our northern winter heating makes the indoor air drier, which makes water loss increase, causing thick blood, slow blood flow, so that patients who originally have atherosclerosis are more likely to occur small thrombosis, the formation of myocardial infarction or cerebral embolism, so patients with cardio-cerebrovascular disease underlying disease should be more Drink more water, add some honey in moderation to keep the stool smooth; In addition, due to the long time closed doors and windows in winter, indoor carbon dioxide concentration increases, coupled with the body’s own decomposition of exhaust gas, often make indoor air pollution, making people feel dizzy, nausea, loss of appetite. Therefore, we should often open the windows to reduce and inhibit the reproduction of germs, especially the people of the cottage fire, but also to avoid the backflow of wind at night and gas poisoning. Finally, it is recommended that we refer to the 16 cornerstones of health: reasonable diet, quit smoking and limit alcohol, proper exercise, and balanced mind for health care. Modern medicine believes that winter tonic can improve the body’s immune function, promote metabolism and make the phenomenon of cold fear improved. Winter tonic can also regulate the metabolism of substances in the body, so that the maximum amount of energy transformed from nutrients is stored in the body, which helps the body’s Yang Qi to rise, laying the foundation for good health in the coming year. But the winter people’s activity is reduced, coupled with a large number of hot food and tonic wine, it is easy to cause increased blood lipids, inducing cardiovascular disease, so the winter “food supplement”, should be rich in protein, vitamins and easy to digest food such as: brown rice, corn, wheat, black beans, peas and other b beans; ginger, leeks, garlic The vegetables such as ginger, leek, garlic, radish, cauliflower, fungus, etc.; mutton, beef, chicken, pork loin and eel, carp, silver carp, scallops, shrimp and other meat; walnuts, cinnamon, chestnuts, sesame and other fruits. Weak elderly people, winter can often eat stewed hen, lean meat, hoof tendons, often drink milk, soy milk, etc., can enhance physical fitness. Patients with cardiovascular disease in winter should reasonably arrange exercise time and control the amount of exercise. When the weather is good, try to choose to go outdoors in the afternoon to absorb more fresh air, so that the body can regulate the body temperature more quickly and accurately and adapt to the changes in climate, because the ultraviolet rays in the sun can resist and kill many kinds of germs, while patients with coronary heart disease, hypertension and hyperlipidemia should also be relaxed, work and rest on time, and do not let the emotional ups and downs too much to avoid the recurrence of cardiovascular and cerebrovascular diseases.
