The autumnal equinox will be held at 9:4 on September 23, Beijing time. On the day of the autumnal equinox, when the sun reaches 180 ° of the longitude of the yellow, Dong Zhongshu said in the Spring and Autumn Flourishing Dews: "The autumnal equinox is half yin and half yang, so the day and night are both cold and hot." In order to promote the culture of Chinese medicine health preservation and disease prevention, and let the public understand and master the knowledge of solar term health preservation, Tianjin University of Traditional Chinese Medicine invited Huang Wenzheng, a famous Chinese medicine nephrologist, to talk about the "autumn equinox solar term and health preservation". The autumnal equinox is the time when "summer fades and autumn becomes cool, and the sun and night are both long". Since then, the trend of yin and yang has really changed, with yin rising and yang declining. In terms of climate, the temperature drops and the temperature difference between day and night increases. Correspondingly, the yang qi of the human body tends to be introverted, so it is easy to show a "lack of autumn" state. Based on this, Professor Huang Wenzheng proposed that the autumn equinox regimen should be preventive, focus on nourishing yin and moistening dryness, and replenish the lung and kidney. Professor Huang Wenzheng pointed out that traditional Chinese medicine believes that the lung is delicate and dirty, with skin and hair on the outside, opening the nose. Therefore, external evils often attack the lung from the skin, mouth and nose, and then turn into other visceral diseases. And the lung likes to moisten and hates dryness, which is easily injured by dryness. After the autumnal equinox, the dry air is more abundant, and the temperature drops significantly, so the dry air in season is easy to combine with the cold air. If the cold and dry qi is too much, or the qi of the human body and lungs is yin deficient, and cannot adapt to climate change, then it is easy to have upper respiratory tract infections such as colds and coughs, which often show headache, body heat, aversion to cold and no sweat, and accompanied by dry lips, dry throat, dry cough and other "cool and dry" symptoms. The upper sense is the inducement of nephritis and other diseases, as well as the aggravating factor of various basic diseases. Therefore, after the autumnal equinox, the elderly and children should pay more attention to prevent problems before they occur, so as to avoid new diseases caused by the upper sense, or aggravating chronic nephritis, chronic obstructive pulmonary disease and other diseases. Nourish yin and moisten dryness. The water begins to dry up at the third autumn equinox. Professor Huang Wenzheng stressed that as the temperature drops, the earth atmosphere shrinks and the phenology becomes increasingly dry. At this time, we should follow the basic principle of "nourishing yin in autumn and winter" and comply with the transformation of yin and yang in nature. The diet is mainly about nourishing yin and moistening dryness to reduce the adverse effects of climate change on the body. You can eat more sesame, sago, glutinous rice, lotus root, mushroom, wax gourd, snow pear, sugar cane, water chestnut, grapefruit, etc. to nourish yin and dryness. For the elderly, the cream with moisturizing effect should be applied appropriately after bathing to avoid skin itching due to too dry skin. In addition, it should be noted that sometimes the throat is dry and the mouth is dry, the lips are chapped, the skin is desquamated, and cold phobia, soreness of the waist and knees, and poor urination are seen. It may be caused by the evil of cold and dryness that blocks the yang qi and causes the kidney yin to coagulate. It is not allowed to simply use yin nourishing drugs. Instead, it is necessary to use warm and warm drugs in combination with warm and warm drugs to dispel the cold qi in the kidney and make the body fluid unblocked, which should play a role in moistening dryness. Professor Huang Wenzheng advocates that it is better to strengthen the lung and kidney after the autumn equinox. Traditional Chinese medicine believes that the lung and kidney are closely related to the respiratory function of the human body. "The lung is the master of qi, and the kidney is the root of qi. The lung is the master of exhaling qi, and the kidney is the master of receiving qi. When yin and yang intersect, breathing is harmony." It can be used to invigorate the lung and kidney. Breathe with your nose and then close your breath. At the same time, bite your teeth and keep your toes firmly on the ground until you can't stand it. Then exhale again for 18 times. Qi closing method can enhance heart and lung function, help maintain kidney qi, and reduce the feeling of "autumn fatigue". However, the practice of "Qi closing Method" should be gradual and not risky
