When the weather is cold in winter, the functions of human organs will decrease, blood vessels will contract and blood pressure will increase. If you don't pay attention to keep warm, it will easily lead to blood vessel rupture, high blood pressure and myocardial ischemia. Pay special attention to the warmth of key parts such as head, back, shoulders, neck and feet. When going out, it is best to wear a cotton hat and scarf, and if necessary, put on a down vest or vest. Second, closely monitor blood pressure. The low temperature in winter is the season of high incidence of cardiovascular and cerebrovascular diseases. Cold will stimulate the contraction of the heart, cause hypertension and vasospasm, and increase the risk of cardiovascular and cerebrovascular diseases. Therefore, patients with hypertension in winter should closely monitor their blood pressure. If they have symptoms such as dizziness, headache, tinnitus, eye swelling, eye pain and numbness of limbs, they should see a doctor in time. Elderly hypertensive patients with a history of cardiovascular and cerebrovascular diseases should pay more attention to the fluctuation of blood pressure. It is not a problem to stick to good habits, stay young and stay away from illness. Many people do not take good maintenance measures in the face of weather changes, and may be troubled by diseases if they do not do well in the high incidence of chronic diseases. In order to be healthy, middle-aged and elderly people should actively care from all aspects, keep healthy, stay away from diseases and improve their quality of life. 1. Strengthen the care for the elderly, including exercise. With the change of weather, many people have a high incidence of chronic diseases. When it is cold in autumn and winter, they don't want to exercise. They always stay at home and feel warm at home, but they don't know that more exercise is an effective way to regulate their bodies. If your blood pressure is high and your blood sugar or blood lipid is unstable, you should choose appropriate exercise according to your physical condition. During exercise, your metabolism will be accelerated, and your circulation will be kept good, so that you can provide blood to the needed parts. Of course, exercise generates more heat, which can keep the whole body warm. People with high blood pressure will find vasodilation after exercise, and the situation of high blood pressure will improve. Exercise consumes calories, blood is sticky and blood sugar is high, which is the correct health care method. 2. Strictly control the diet. When the weather changes, middle-aged and elderly people can adjust their diet and take proper care of their bodies, thus effectively controlling the development of chronic diseases. Many people don't eat properly. When the weather is cold in autumn and winter, they think that eating more nourishing food can safely spend the winter, but they don't know that it is easy to have more fat, more cholesterol and higher uric acid index, which may induce gout. These incorrect behaviors need to be corrected. Even if winter comes, the diet should be light and refuse to be greasy. In addition, don't eat too much high-calorie food and avoid overeating.
