On September 7th, we welcome the third solar term of autumn - Bailu, which is also the fifteenth solar term among the twenty-four solar terms. Xie Hao, Deputy Chief Physician of the Cardiovascular Department at Beijing Hospital of Traditional Chinese Medicine affiliated with Capital Medical University, introduced that "white dew" means that the weather is gradually getting cooler, the temperature difference between day and night is increasing, and dew condensation is common in the morning, hence the name "white dew". Traditional Chinese Medicine believes that after Bai Lu, the natural yang qi gradually decreases and the yin qi gradually grows, and the climate is mainly characterized by dryness, which can easily damage the lungs. Therefore, the focus of health preservation at this time is to prevent dryness, moisten the lungs, nourish yin and keep warm, while paying attention to strengthening the spleen and stomach to improve the body's ability to adapt to seasonal changes. Xie Hao reminds that in terms of diet, the principle of "reducing bitterness and increasing acidity" should be followed, and more foods that nourish and produce fluids should be consumed. For example, pears, honey, Tremella fuciformis, lilies, sesame seeds, glutinous rice, and other medicinal herbs such as ginseng, Ophiopogon japonicus, and yam can also be used to make soup to moisten the lungs and nourish yin. Meanwhile, supplementing fruits and vegetables rich in vitamin C, such as citrus and grapes, can help boost immunity. In addition, spicy, grilled, fried, and cold foods such as chili peppers and iced drinks should be avoided as much as possible to prevent dryness and damage to yin, which can affect lung and spleen function. It is advisable to go to bed early and wake up early in daily life, following the natural trend of the convergence of yang energy. ”Xie Hao introduced that due to the large temperature difference between day and night, it is necessary to add clothes in a timely manner in the morning and evening, and pay special attention to keeping the abdomen, joints, and feet warm. There is a saying among the people that "white dew should not be exposed to the body, and if you catch a cold, you are prone to diarrhea". When sleeping at night, you should close the windows and covers to prevent the invasion of cold pathogens. In terms of exercise, it is recommended to choose low-intensity activities such as walking, Tai Chi, and Baduanjin. It is advisable to sweat slightly to avoid excessive exercise that can cause damage to the body fluids. During the period of white dew, common respiratory and digestive system problems occur. Xie Hao said that due to the invasion of dry pathogens into the lungs, many people may experience symptoms such as dry mouth and throat, dry nose and bleeding, dry cough with less phlegm, and dry skin, which can easily trigger colds, bronchitis, and so on. Traditional Chinese medicine should take "moistening" as the method. You can properly drink lily snow pear soup, Arhat fruit tea, or take Yangyin Qingfei pills, Qiuli ointment, etc. to relieve symptoms as instructed by your doctor. People with weak spleen and stomach should be cautious when eating raw and cold foods. Ginger and red dates can be added to warm them up. The frail and elderly population can also enhance their positive energy through moxibustion at acupoints such as Zusanli and Feishu. Autumn can easily trigger the emotion of 'sad autumn'. Xie suggests participating in more outdoor activities, gathering with family and friends, and cultivating a positive and optimistic attitude. In the afternoon, it is advisable to listen to soothing music or engage in deep breathing exercises to help maintain emotional stability. However, excessive thinking and prolonged solitude should be avoided. White dew is an important transitional period for nourishment in autumn and winter. In addition to preventing dryness, it is necessary to balance strengthening the spleen and keeping warm, in order to achieve physical and mental harmony and a healthy autumn. ”Xie said. (New Society)
