In the early years, magnetized water, magnetic therapy pillows, magnetic stickers and many other daily necessities related to magnetism began to enter our lives. Is it scientific to use magnetic health care products? Many people are skeptical about this. Because, it seems that people who care about magnetic health care have not received too many health care effects, and those who disdain magnetic health care have not suffered more health damage. Scientific research believes that the human body really needs magnetism, just like air and water; The human body needs to "replenish magnetism", just like medicine and food supplements in the four seasons. People know that the damage to health caused by people leaving water and air will be shown in a short time, but no one can intuitively grasp the influence of magnetism on human body. Scientific research shows that the change of the earth's magnetic field will have a great impact on human magnetism. Without the earth's magnetic field, high-energy particles and X-rays in the universe would pose a fatal threat to life on earth. These radioactive materials are deflected by the earth's magnetic field, and most of them flow to the poles along the direction of the magnetic field, and then scatter into the universe. When the local magnetic field changes, the magnetic field of human body will also change accordingly, especially the abnormal electrical changes of body fluids such as blood and lymph, which will affect the physiological function of human body. The disorder of human magnetism will lead to growth retardation, abnormal physiological function and increased incidence of various diseases. The most significant effect is that it will lead to autonomic nervous dysfunction, premature cell aging, increased blood viscosity and blood deposition blocking blood vessels. These factors are related to the high incidence of hypertension, cardiovascular diseases and chronic fatigue in modern society. However, in the millions of years of human reproduction and evolution, human beings have not been greatly affected by magnetic disorder. However, various factors in highly developed modern society have increasingly led to the lack of human magnetism. Specifically, rows of reinforced concrete high-rise buildings in modern cities, wires and cables as dense as cobwebs and criss-crossing metal pipes brought about by the development of modern telecommunications and transportation have all become barriers to natural magnetic fields. On the other hand, people's eating environment has also undergone major changes. The water they drink is no longer directly from rivers and lakes, but is transported through magnetic iron pipes or pure water. On the other hand, most foods are processed or elaborately made, lacking more minerals. These factors, on the one hand, directly reduce the amount of natural magnetic field radiation received by the human body, but also seriously weaken the ability of the human body to receive magnetic field radiation. Therefore, it affects the normal functioning of human physiological functions and leads to the high incidence of many diseases. Magnetism is very important to human health, and the damage of lack of magnetism to human health is subtle. As modern people with a growing awareness of self-care, they should be aware that they may have magnetic defects. This requires people to scientifically "replenish magnetism" in various ways, just like paying attention to medicine and food supplements. For example, when sleeping, try to make your body follow the north-south direction and make your cells more orderly under the action of natural magnetic fields; Drink magnetized water properly to directly magnetize yourself and promote metabolism; Eat more vegetables and fruits rich in minerals to enhance the body's ability to receive magnetic radiation; Scientific use of magnetic daily necessities, such as magnetic pillows, shoes, belts, etc. Sticking magnetic plaster on specific acupoints can increase human magnetism and improve physiological functions.
