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.. Prof. Nie Bin said that he often encounters patients who are afraid of cold in summer. From the perspective of Chinese medicine, people with this condition are actually suffering from Yang deficiency, a lack of Yang energy in the body. What are the symptoms of Yang deficiency? Since traditional Chinese medicine knowledge is not popular in the society, many people do not understand what changes and manifestations will occur in the body when Yang Qi is weak. Generally speaking, the following symptoms mean that the body’s Yang energy is weak or damaged: 1. If women have Yang deficiency, they tend to look white, lose their red color, and look like they lack blood; 2, decreased resistance, apparently afraid of wind and cold, especially sensitive to the change of seasons, and get cold and flu if they are not careful; 3, poor appetite or thin, unformed stools, often chronic diarrhea, especially after staying up late, after eating cold food, after exertion or cold; 4, a little activity, even if Up three floors will feel panic, shortness of breath, but also particularly prone to sweating, polyuria at night; 5, women are depressed, less breath and lazy, and even will have symptoms of menstrual disorders; and men are manifested as waist pain, impotence, premature ejaculation, etc. The lifestyle and environment of urban people often lead to Yang deficiency: 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, while earth feeds man’s yin with food. Breathing in 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 is good, Yang Qi (called day Yang) sufficient, can supplement the body’s Yang. 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 frequently invaded, coupled with the usual lack of exercise or no exercise, sweating less and less, over time, damage to Yang. Often diet cold cold things easy to hurt Yang Qi. Guangzhou people like to drink herbal tea, regardless of physical condition, all year round to take bitter cold heat herbal tea, which damages the body viscera Yang Qi, resulting in Yang deficiency. Abuse of antibiotics. From the Chinese medicine taste to analyze, antibiotics belong to the bitter cold nature, bitter cold easy to attack Yang Qi, to Yang Qi deficiency, the physique becomes weak. Often sleep late. For example, watching football games, playing cards, singing K, playing games until late at night or even overnight. Health often says “work at sunrise, rest at sunset”. “The so-called Zhang is outwardly dispersed, especially at night Yang Qi should be collected, should return to its 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. Chinese medicine emphasizes “nourishing Yang in spring and summer, nourishing Yin in autumn and winter”, which is very effective in avoiding many diseases. People with insufficient yang energy can gradually improve their yang energy through diet, exercise, medication and external Chinese medicine to achieve a healthy state of balance between yin and yang. For prevention, eat more Yang-supplementing foods, such as mutton, dog meat, onion, ginger, garlic, shrimp, leek, walnut and pepper, and less cold and raw foods, such as cucumber, lotus root, pear and watermelon. Exercise, because “movement is Yang”, so people with Yang deficiency should strengthen physical exercise, such as walking, jogging, taijiquan, eight duanjin, etc., can also often do sunbathing, air baths, strong Yang Qi. However, diet and exercise to nourish Yang 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.
