The cold climate in winter, the reduction of human movement and the slowing down of qi and blood flow make colds, bronchitis, coronary heart disease and cerebrovascular disease the most prevalent diseases in winter. Winter health care requires prevention of these diseases. Cold and bronchitis The occurrence of cold and bronchitis is closely related to feeling the evil of wind and cold. The cold climate in winter, weak people such as children and the elderly, the trachea, the mucous membrane barrier ability of the whistle is weak, easy to be attacked by wind and cold and cold; In addition, the cold and changeable climate in winter can easily induce a variety of chronic diseases, such as chronic bronchitis, bronchiectasis and other diseases. Prevention program 1, the key to prevent these diseases is to strengthen the physical fitness and prevent cold and keep warm. In Chinese medicine, it is said that “if the righteousness exists inside, the evil cannot dry up” and “where the evil comes together, its energy will be weak”. 2, for the weak children and the elderly, should pay attention to daily diet and nutrition and appropriate physical exercise, in order to enhance physical fitness, so that the body is full of positive energy, enhance the ability to resist disease. 3, winter residence should be warm, clothing should be warm, light, comfortable, to prevent the feeling of wind and cold evil, to reduce the chance of morbidity. Coronary heart disease and cerebrovascular accidents are prone to coronary heart disease and cerebrovascular accidents in winter, which is closely related to the climate characteristics of winter and the physiological characteristics of the human body in winter. In winter, the cold climate, fatty diet and lack of exercise slow down the blood flow and increase blood viscosity, which can easily lead to thrombosis, vascular blockage or rupture of blood vessels for people with previous underlying cardiovascular and cerebrovascular pathologies and elderly people with reduced vascular elasticity, and lead to coronary heart disease and cerebrovascular accidents. The key to preventing these diseases is to moderately increase physical exercise to help the circulation of Qi and blood and improve the body’s blood circulation status. 1, eat less fatty, sweet and thick taste, emotional stability. 2.People with previous heart and brain-related underlying diseases such as hypertension, dyslipidemia and diabetes should adhere to medication to control blood pressure, lipids and blood sugar in a more stable and safe range to reduce the incidence of unconscionable and cerebrovascular events. The occurrence of coronary heart disease and cerebrovascular disease is most common at night during sleep and early in the morning when waking up. This is related to the slowing down of human blood flow and the increase of blood viscosity during night sleep, which makes it easy for thrombus to form and develop, leading to sudden death of people at night; or thrombus has formed at night, but the thrombus is small and not yet dislodged, and when waking up early in the morning, due to the sudden action, it causes the thrombus to dislodge and enter the blood vessels in the heart or brain with the blood flow, causing the blockage of the corresponding blood vessels and developing. Therefore, elderly people should drink a glass of warm water before going to bed, which can effectively dilute the blood and reduce the incidence of unconscience and cerebrovascular events at night; in addition, when waking up in the early morning, do not sit up suddenly and move too vigorously, especially for the elderly, it is better to lie in bed for a few minutes after waking up, and then get up slowly to get out of bed and get dressed, which can also reduce the occurrence of such diseases to a certain extent. Therefore, I caution you: there are basic cardiovascular and cerebrovascular related diseases, such as hypertension, dyslipidemia, diabetes, coronary heart disease, especially for the elderly, must adhere to regular medication treatment, do not take it lightly, it is best to control blood pressure, lipids, blood sugar, etc. in a safer range to reduce the incidence of unconscience, cerebrovascular events. In winter, the earth is frozen, everything is silent, the climate is cold, the sunshine time is shortened, and outdoor activities are reduced, all of which tend to make people’s mood in a more depressed state, leading to mental discomfort. For these characteristics, you can improve and adjust the low emotional state by increasing the amount of exercise, cultivating healthy and rich hobbies, and communicating with people more. Outdoor sports and exercise, music appreciation, old friends, etc. can help to break the dreary winter life, enrich daily activities, stimulate enthusiasm for life, so that the spirit of uplifting, high morale.
