Modern people are either forced by life or by the environment to keep depleting their yang energy every day, or until the root is injured and disease is born. In order to improve the quality of life and live a healthy life, the following points should be avoided in urban life so as not to cause unnecessary loss of yang energy. First, non-time rest, Yang does not return to the root of Chinese medicine that the best time to sleep for the three hours of “Hai Zi Chou”, according to the doctrine of the midday flow, when the three jiao, bile, liver meridian in order. At this time, it is advisable to exclude distracting thoughts, meditate and calm the mind to nourish the vital energy. Lie down with your knees bent and gradually fall asleep. Ziqi (11pm-1am) corresponds to the bile meridian, which is equivalent to the spring of the year, “the plan of the year lies in spring, the plan of the day lies in the morning”. Ugly time (1:00-3:00 am) corresponds to the liver meridian, a good sleep is the best way to nourish and protect the liver. The ancient people followed the law of heaven and earth, following the “sunrise and work, sunset and rest”, in line with the work and rest of heaven and earth, so they can be clear and full of energy and essence. People today are not, with electric lighting, television, computers and other entertainment facilities, people have been accustomed to sleep late, rarely sleep at night, and even at the time of the child “to exhaust its essence, to dissipate its true”, and the time of the child for a Yang, for the alternation of yin and Yang, if you can not sleep, the direct damage is a Yang in Kan, in the long run, Kan Yang loss Deficiency, various diseases should be born. Second, cold food, and good sweet and spicy with the integration of Western and Chinese food culture and the popularity of home appliances such as refrigerators in life, modern people’s eating habits have slowly changed. Especially young people prefer cold food, which can seriously damage the spleen and stomach Yang, especially in the summer, the body Yang out, the stomach and intestines instead of a cold state, so the summer should be a light diet, warm food and hot drinks. If cold food and cold drinks are used to relieve the summer heat, it is a mistake of “deficiency”, the spleen and Yang is damaged, then the transport and transformation is unfavorable, abdominal pain, diarrhea, weakness, wasting, etc.; like to eat sweet, greasy and thick, the body can not transport and transformation of phlegm and dampness, wet for the yin, and heavy sticky, obstructing the operation of Yang Qi, leading to Yang depression and Yang deficiency evidence; spicy food makes people mentally Excessive dissipation of yang energy will also lead to yang deficiency. Third, do not avoid the wind, summer typhoid “Nei Jing” mentioned “false evil thief wind, avoid the sometimes”, “the sage avoid the wind as avoiding the stone”, it can be seen that the ancients on the wind is guarded against, because the wind is not only the longest of all diseases, but also the first official of the six sexes, the wind invades the muscle surface To the table deficiency, then other evil can take advantage of the deficiency and enter, especially the cold on the human body’s greatest damage, cold is water can put out fires, the most injury to people Yang Qi, and Yang Qi for the life of the person, Zhang Zhongjing with “Typhoid” into the medical sage, you can see the importance of avoiding wind and cold. Winter outside the cold wind, water ice chap, but the human pores tighten plus thick clothes cover the body, the wind and cold of the evil and not easy to invade the body, while the summer Yang Qi out of the pores open, is the same as the door is wide open, at this time, if you immediately blow the fan or into the air conditioning room, the wind and cold of the evil will go straight into the skin, tendons and veins, bones and joints, if not timely discharge of cold, more will invade the six bowels and organs, and even into incurable diseases, it can be seen that man-made evil harm to the human body far more than the natural gas. Fourth, improper exercise, Yang Qi outside the Zhang modern people advocate the concept of “life lies in sports”, physical discomfort or sickness is often considered the lack of exercise, and began to exercise regularly and consistently, but most people do not benefit from exercise, which is the principle of unknown exercise and unreasonable exercise. In fact, the essence of exercise is to strengthen the circulation of qi and blood, which is suitable for people who still have sufficient yang energy but do not have good qi and blood, such as those who eat thick and greasy food, those who are sedentary and do not move, or those who think too much, but never for those who have a large deficit of qi and blood, because the deficient people do not have enough yang energy to fix the function. After exercise, Yang Qi is dissipated, resulting in more Yang Qi deficiency. In addition, exercise is hair, should be spring and summer daytime, and now many people are evening exercise and fitness, seemingly to make up for the lack of daytime exercise, in fact, is a violation of the “growth collection” sequence, “Su Wen – Four Seasons of the Great Theory of the Adjustment of God” pointed out that the winter March to “not disturb the Yang “The winter sweating affects the collection of Yang, especially the kidney Yang is damaged. Fifth, the work of annoyance, strong fire eating gas today’s busy work, fierce competition, life pressure, worries also increased, “Su Wen – angry Tong Tian Theory” said: “Yang Qi, annoyance is Zhang. The human body Yang Qi relies on material and mental stimulation work outside for a long time, do not know timely collection of rest, on the one hand, will lead to the deficiency of Yang Qi, in addition, Yang Qi is too fatigued resulting in the inability to enter the Yin collection, resulting in insomnia, and even neurasthenia, so that a vicious circle. The main theme of today’s society is development and consumption, both of which are constantly increasing human desire, desire is the fire of the spirit, and is the evil fire strong fire, “Nei Jing” mentioned “strong fire eats gas”, so desire will also consume the body’s positive energy. Laozi admonishes us to be content with less desire, to “not be virtuous, not to value rare goods, not to see what we desire”, which actually means to reduce our desire, so as to save Yang Qi and not to let it die prematurely.
