It is now the coldest time of the year. According to Chinese medicine, “the lungs are delicate organs” and are most susceptible to external aggressions, and in winter they are more prone to colds and flu, or aggravation of existing respiratory diseases. This shows the necessity of nourishing the lungs in winter. Here’s how to nourish the lungs in winter to prevent respiratory diseases. First, pay attention to warmth, with the outside temperature changes in time to increase clothing, do not make the cold invade the body. Special attention should be paid to the back and foot warmth: “back for the Yang in the Yang”, for the “Yang pulse of the sea”, is the main trunk of the circulation of the Governor’s vein, the general supervision of the body Yang. If the back is not kept warm, the wind and cold evil through the back meridian and invade the human body, damage Yang, so that the balance of yin and Yang is disrupted, the body’s immune function is reduced, the ability to fight disease is weakened, causing the recurrence of old diseases or aggravation. There is also a common saying that “cold starts from the feet”, the feet are yin to the head and have less yang energy. The feet are far from the heart, the blood supply is insufficient, prolonged sagging, poor circulation, thin subcutaneous fat layer, poor insulation performance. Once the feet are cold, they will cause vasoconstriction of the mucous membrane of the upper respiratory tract through nerve reflexes, reducing blood flow and resistance to disease, causing people to catch a cold, or to relapse from old diseases such as asthma and bronchitis. Therefore, keep your shoes and socks warm and dry in winter, wash and dry them frequently, and scald your feet with warm water before going to bed. Secondly, to improve the cold tolerance of the skin and nasal mucosa through exercise is the key to winter health. Wash your face with cold water in the morning to enhance the ability of the nasal mucosa to adapt to cold air. A morning walk outdoors for half an hour of aerobic exercise can enhance the ability to resist the cold. Do deep breathing regularly to increase lung capacity and enhance physical fitness. But there are a few points to note about winter exercise: First, the early morning frost and cold, fog, air quality is poor, it is easy to go out to exercise at this time to suffer from the cold, fog and turbidity. So it is not recommended too early morning exercise; second is not too much exercise and “sweating” to avoid damage to the lung gas, but also to avoid sweating after the skin couples open and cause the invasion of cold, the most suitable exercise or walking and playing Taijiquan. Third, rest and relaxation should be regular, and sleep for seven or eight hours at night. Chinese medicine classic “Yellow Emperor’s Classic of Internal Medicine” has recorded: “in March, sleep early and get up late, must wait for daylight, this winter gas should be the way to nourish the hide.” In winter, it is appropriate to sleep early and get up late to nourish the yin and hide the spirit, so that the next day is full of energy. Of course, the “late rising” here does not advocate sleeping in, but rather that people should not get up in a hurry when it is still light. Too much sleep and not enough sleep will lead to mental fatigue and human fatigue, resulting in a decline in metabolic function and harm to physical and mental health. Fourth, to keep indoor air circulation. Cold weather makes people prefer to stay indoors for a long time, in order to keep warm, indoor air is often not circulated, increasing the chances of the spread of various viruses and bacteria, also making the incidence of respiratory diseases increased significantly. Therefore, it is also necessary to open the windows frequently in winter to keep the indoor air fresh and prevent lung diseases. Finally, winter food therapy also plays a vital role in nourishing the lungs. The Su Wen? This is one of the principles of traditional Chinese medicine to maintain health according to the time of year. It is said that in autumn and winter, everything collects and hides, so it is advisable to follow the times and nourish the body, to protect and hide the Yin essence, so that the essence can be gathered internally to moisten and nourish the five organs. All have loss of yin essence should be avoided. Mandarin oranges, persimmons, pears, pomegranates, grapes, etc. have the effect of moistening the lungs, is the best fruit for lungs in winter. Winter climate is dry, in addition to drinking more water, you should also eat more food with nourishing Yin and moistening dryness, nourishing the lungs and generating fluid. Such as honey to clear the lungs and moisten dryness, often used in the treatment of lung dry cough, but also available almonds, lily of the valley, barley kernel, Chinese yam, etc. to benefit lung energy. In addition, you should eat as little spicy food as possible, not eat more barbecue, and avoid eating greasy and thick food to prevent aggravating the symptoms of lung dryness.
