Summer is supposed to be the season of “where it’s cool to stay”, some people like to blow the fan, air conditioning, but some people are different, they feel very cold in summer blowing the fan, do not dare to blow the air conditioning, a little carelessness in the cold will catch a cold, every day, the spirit of the sleepy, but also often feel lumbar acidity, limb weakness, etc.. Professor Nie Bin said that he often encounters patients who are afraid of cold in the summer. From the perspective of Chinese medicine, people with this condition are actually Yang deficiency, a lack of Yang energy in the body. What are the symptoms of Yang deficiency Because traditional Chinese medicine knowledge is not popular in society, many people do not understand what changes and manifestations the body will have when Yang is weak. Generally speaking, the following symptoms mean that the body’s yang energy is weak or damaged: 1. If a woman has Yang deficiency, her face tends to be white and lose its rosy color, and she looks like she lacks blood. 2. Decreased resistance, apparently afraid of wind and cold, especially sensitive to seasonal changes, and will catch a cold if not careful. 3, poor appetite or thin, unshaped stools, often chronic diarrhea, especially after staying up late, after eating cold food, after exertion or cold, diarrhea began. 4, a little activity, even up three floors will feel panic, shortness of breath, but also particularly easy to sweat, night polyuria. 5, women are depressed, less breath and lazy, and even will have symptoms of irregular menstruation; while men show soreness in the back, impotence, premature ejaculation, etc. The lifestyle and environment of urban people often lead to Yang deficiency: 1. Serious air and water pollution. The Yellow Emperor’s Classic of Internal Medicine says that man is born of heaven and earth, and that heaven feeds man’s yang with qi and earth feeds man’s yin with food. Breathing in the polluted air, Yang is bound to be damaged. Some people can not get up all day and night, to the mountains for a few days to look better. Mountain air quality, yang (called day Yang) is sufficient to supplement the body’s Yang. 2, cold air conditioning is very common. Units have air conditioning, air conditioning in shopping malls, blowing air conditioning at home at night, people stay in the air-conditioned environment almost all day, Yin cold gas invade frequently, coupled with the usual lack of exercise or no exercise at all, sweating less and less, over time, damage to Yang. 3, often diet cold and cold things easy to hurt Yang. Guangzhou people like to drink herbal tea, regardless of the physical condition, all year round take bitter cold heat herbal tea, which damages the body viscera Yang Qi, resulting in Yang deficiency. 4, abuse of antibiotics. From the Chinese medicine taste to analysis, antibiotics belong to the bitter cold nature, bitter cold easy to attack Yang Qi, to Yang Qi deficiency, the physique becomes weak. 5, often sleep late. For example, watching football games, playing cards, singing K, playing games until late at night or even overnight. The health care often said “sunrise and work, sunset and rest”. “Yang qi, annoying is Zhang”, the so-called Zhang is to the outside, especially at night Yang qi should be collected, should return to the original position. If you’re tired of working, you can’t return to your position, and it will slowly dissipate. Spring and summer is the time to nourish Yang, so how can people with Yang deficiency be trained in Chinese medicine? Prof. Nie Bin offers his insights: Chinese medicine emphasizes “nourishing Yang in spring and summer, and nourishing Yin in autumn and winter”, which is very effective in avoiding many diseases. 1, yang deficiency can be related to the four aspects of diet, exercise, medicine, Chinese medicine external treatment, gradually enhance the body yang, to achieve a healthy state of balance between yin and yang. Prevention can be done by eating more Yang-supplementing foods, such as mutton, dog meat, onion, ginger, garlic, shrimp, leek, walnuts, pepper and other foods, and less cold and raw foods, such as cucumber, lotus root, pear, watermelon, etc. 2, exercise, because “movement is Yang”, so, Yang deficiency of the body, to strengthen physical exercise, such as walking, jogging, taijiquan, Badaogan, etc., can also often do sunbathing, air bath, strong Yang. However, diet and exercise to nourish yang qi is slow to take effect. Therefore, Chinese medicine has internal and external methods of Yang supplementation. External treatment is based on the Chinese medical theory of fire as Yang, moxibustion to warm Yang, take fire moxibustion therapy, fire therapy in the body is Yang meridians, the Governor’s vein and other parts of the treatment, dredge Yang meridians and veins, stimulate the body’s Yang energy.
