The most beautiful thing in the world is life, and the most magical thing in the universe is life. But who is in charge of life? Who decides and controls the course of life? Who is deciding people's health, longevity and death? Who gives and conveys these instructions when you want to hug your lover? Are those cells and organs? No, modern physiology has made it clear that it is your bioelectric system-including brain consciousness and thinking based on bioelectricity, and nerve impulse based on bioelectricity. Bioelectricity is the dominant factor of human body, so it is closely related to the occurrence of human diseases. Excessive environmental electromagnetic field will have adverse effects on human body, leading to some serious diseases. In 1970s and 1980s, epidemiologists and biophysicists noticed that ionizing radiation produced by extremely low frequency electromagnetic fields was closely related to human cancer and other diseases. From 65438 to 0979, an epidemiological survey was reported in Britain. Residents living under high-voltage transmission lines are at higher risk of leukemia and central nervous system tumors than those living in other places. By the 1980s, there had been ten studies in Britain, which once again proved that when workers and residents were exposed to low-frequency electromagnetic fields, the incidence of leukemia, cancer and other diseases increased significantly. A group of scientists from the University of North Carolina said in the bulletin of the National Cancer Research Center that their analysis of more than 1.4 million death certificates issued by 24 states in the United States showed that the mortality rate of female breast cancer working in electromagnetic fields was 38% higher than normal. On the other hand, from the bioelectricity point of view, cancer is caused by malignant proliferation of cells and tissues in local tissues of human body, and its negative potential is equivalent to that of embryonic tissues. From the bioelectricity point of view, the treatment of cancer is to eliminate the high negative potential of local cancer tissues. Studies have shown that the occurrence of atherosclerosis is also directly related to human bioelectricity. When some factors lead to the decrease of blood composition or the decrease of net negative charge on arterial wall, its electrostatic repulsion will be weakened. This will lead to poor blood flow, and the combination of positively charged substances and negatively charged substances will help to form deposits on the arterial wall. This seems to indicate that the compound process of material ionization (producing biological plasma) and biological plasma occurs all the time in human body. Excessive recombination (polymerization) of human biological plasma will produce deposition in blood, leading to "qi stagnation and blood stasis" and atherosclerosis. To reverse it, the fundamental way is to enhance the bioelectricity of human body and increase the negative charge in human body. To achieve this goal, the best way is to maintain moderate exercise and strengthen physical exercise. Why can exercise keep fit? Because exercise can make the human body produce "friction", which can generate electricity, so that charged particles in the human body increase, that is, "qi" is supplemented and blood runs smoothly. At the same time, due to the repulsion of charges with the same sign, blood substances such as red blood cells are not easy to agglomerate, arteriosclerosis and thrombosis are not easy to occur, and microcirculation is smooth, thus promoting human health. However, excessive intense and long-term high-intensity exercise consumes too much energy (bioelectricity), which leads to negative growth of bioelectricity (internal qi) of human body, so it will damage health. Studies have proved that the movement of organisms is accompanied by bioelectricity, such as piezoelectric effect, which is one of the necessary conditions for normal metabolism of organisms. Osteoporosis is a common disease of astronauts working on spacecraft for a long time, which is caused by the lack of piezoelectric effect under long-term weightlessness. So at present, fracture patients have been required to do some necessary activities in the later stage of recovery to speed up the recovery. Experiments have proved that even if the bones of fracture patients are dislocated, as long as they adhere to the same normal activities as before, the dislocation can be eliminated after one stage. Because the negative potential generated by normal activities will accelerate the growth of useful parts, while the positive potential will gradually eliminate useless parts. The research also shows that health-preserving and breath-regulating exercise can enhance human bioelectric current, accelerate the combination of nerve conduction, electrical conduction, electron flow and oxygen, and accelerate the electron transfer (electron flow and mitochondria) of oxidative respiratory chain. These research results fully show that "dynamic work", "heart-regulating", "qi-regulating" and "body-regulating" in physical exercise and traditional health preservation methods are all realized by strengthening human bioelectricity and promoting the normal circulation and flow of human bioelectricity through exercise and friction. These methods grasp the fundamental elements of human health, so they can achieve the effect that drugs can't.
