First of all, why sunbathe in the dog days?
Because there are many acupuncture points on both sides of the spine on the back of the human body, there are also bladder meridian and Du meridian, which are in charge of the yang of the whole body and can nourish the bladder meridian and Du meridian after the back is dry.
The back is the yang of the human body, and some people often have chills on their backs, indicating that the cold and humidity in the body are heavier. Once the wind-cold enters the body, it will seriously damage the yang, which is not conducive to health. The working efficiency of the five internal organs of human body is supported by the yang of human body. If you know how to sunbathe your back, you can make your body full of yang and help improve your body's resistance.
Second, can drying the back in the dog days really make up the yang?
It can supplement the essence of the sun, get in close contact with the sun, and absorb the "Yuan Yang" of the sun by drying the back, which can not only enhance the essence of the sun, improve physical fitness, but also dispel the old cold.
There is a saying in Chinese medicine: the abdomen is yin and the back is yang. Because for the human body, the yang meridian runs mostly in the back and the yin meridian runs mostly in the chest and abdomen. There are two major meridians in the back, and the governor meridian governs the yang, which is easy to stagnate cold. If the yang is trapped in the Du meridian, the human body will have "problems", such as low back pain, leg pain, leg cold, leg cramps and so on.
Third, what are the benefits of drying your back in the dog days?
Cao Tingdong, a health care expert in Qing Dynasty, especially praised the sunbathing method, pointing out that sunbathing is helpful to supplement human yang. There is a cloud in his monograph "Old Man's Constant Words": "Sitting with your back to the sun is the so-called' mystery of negative sun'. The spine is slightly warm, which can make the whole body unobstructed. The sun is the essence of the sun, and its light makes people yang, which is extremely beneficial. "
Doing enough sunbathing in dog days can not only replenish the body's yang, but also get rid of chronic diseases. Chinese medicine pays attention to the correspondence between man and nature. Sunbathing is a good method of qi and blood circulation and yin and yang harmony, which has multiple effects such as mobilizing human disease resistance and improving human metabolism.
1, drying your back can make your body sweat slightly.
The ancients called sweat pores Fu Xuan, sweat pores and the gate of hell. The so-called Fu Xuan, pore is only its narrow interpretation. Liu, a famous doctor in the Jin Dynasty, explained this more subtly: nothing, human viscera, fur, muscles, fascia, bone marrow, slaves and everything in the world are the portals of qi movement. Fu Xuan refers not only to pores, but also to criss-crossing channels (microcirculation) invisible to the naked eye.
If Fu Xuan is blocked, qi can't pass normally (up and down), nutrition can't get in, and metabolic waste can't get out, people will easily get sick. According to the metaphor of traditional Chinese medicine, sweating like rain is the embodiment of harmony between heaven and earth, and sweating is also the embodiment of harmony between yin and yang of the body. Sweating properly in dog days can effectively dredge Fu Xuan, expel latent evil, and achieve the effect of recovery from illness.
Our bodies excrete waste in three ways, namely, through stool, urine and sweat. Studies show that urine and sweat are two main ways to eliminate liquid waste, and it is found that some wastes are discharged through sweat much better than urine.
2. The yang meridian of the human body mostly runs on the back, and the limbs are the foundation of yang.
As far as human meridians are concerned, the Du Meridian in the middle of the back is the "Sea of Yang Meridian", which dominates the whole body, while the Bladder Meridian runs through the whole body from head to toe. The two meridians are easy to stagnate cold, and drying the back is helpful to the generation of yang in Du meridian and bladder meridian, and improves the gasification ability of the body. With sufficient yang, you naturally have the ability to expel all kinds of exogenous pathogens and let the sick qi come out from here.
Back in the farming era, farmers worked with their backs to the loess all day. Especially in the busy farming season, I work in the sun every day. Contemporary workers leave early and return late, and they can only see a little sunshine on the road; When I entered the office, I had to let the cold air conditioner blow at me. Therefore, most farmers are full of yang, while most white-collar workers are weak and cold.
Neijing says that "limbs are the foundation of all yang" and limbs are the second heart of human beings. The zang-fu organs of the human body are hidden in the qi of Shui Gu, and the essence of the five zang-fu organs is related to the yang of the limbs. The blood gas of the zang-fu organs passes through the the twelve meridians and 15th collaterals, and comes out of the veins. It should combine with the earth and qi to form a cloud, which is a process from yin to yang. Yang flows from the well point at the end of the limbs through Shu Hui into the veins and into the five internal organs, which is a process from Yang to Yin. If there are no limbs, people also have yang, but they can only come down from the skin, and the room for maneuver is too limited. The return of yang in the limbs is similar to the rainy weather. The higher it is, the wider it is, the better the weather is, and the stronger the yang returns.
Therefore, the dog days are a good opportunity for us to return to tradition. By drying the "Yuan Yang" that absorbs sunlight on the back and limbs and sweating properly, the yang can be enhanced and the physique can be changed.
Fourth, "but blindly following the trend is not desirable!" In this regard, the following are some points and taboos:
1, key points:
(1) Suitable for people: those with deficiency-cold constitution and excessive cold and dampness, and those who often have diarrhea in loose stool, have cold limbs and are afraid of cold.
(2) For the first time, choose the sun at 8-9 am or after 3 pm, and bask for about 20 minutes to understand the body's endurance. If you feel comfortable, you can accept it and increase the time in turn. It is generally recommended to sunbathe for 30-60 minutes.
(3) It is recommended to rest for half an hour before drying. If you don't eat lunch, sweating on your back and high temperature can easily lead to hypoglycemia, dizziness and palpitation.
(4) You will sweat a lot in the sun and need to replenish water in time. You can drink sour plum soup, mung bean soup and light salt water at room temperature. At the same time, carry warm water and heatstroke prevention and cooling drugs, such as ten drops of water, Ren Dan and essential oil. In case of emergency.
2. Taboo:
(1) People who are allergic to ultraviolet rays cannot bask in it; People with hypertension, hyperlipidemia, diabetes and coronary heart disease can't bask in the sun; People with deficiency of both qi and yin or excess of yang are forbidden to bask in the sun; Old people should be careful in the sun and need family to accompany them; Pregnant women are not allowed to bask in the sun; You can't bask after drinking wine.
(2) During sweating, it is forbidden to blow and directly enter the air-conditioned room. As soon as I entered the air-conditioned office, the whole sun turned off, and I immediately felt chest tightness, nausea and vomiting. This is caused by heat blockage, and there is no way out. I need to scrape, bleed and release heat immediately.
(3) It is best to avoid strong wind and cold water in the shade after drying. Be sure to wait until the sweat stops before entering the air-conditioned room and get your coat ready.
(4) Don't expose your head directly to the sun. The head belongs to the sun, and long-term exposure will lead to dizziness, heatstroke and chest tightness. It is recommended to take an umbrella or cover your head with a hat.
These are some knowledge of sunbathing in the dog days. There is a folk saying that "everything grows by the sun". Sunshine is the basis of normal human existence, and everyone should know how to make good use of nature's gifts to maintain their health ~
