EnglishFor some workers who are engaged in the production of magnetic materials or those who have used magnetic material products for a long time, there is a doubt that long-term exposure to magnets will affect their health if they live in areas with high magnetic fields. The answer is that magnets will not have adverse effects on the body, and magnetic materials can be used with confidence. With the rapid development of science and technology, magnets are also used in magnetic therapy, so what effect does high-tech magnetic therapy technology have on the human body?
The earth itself has a very strong magnetic field, so people themselves have a kind of adaptation and even dependence on magnetism. A weaker and more stable magnetic field is beneficial to the body, and magnetic therapy is often used in medical treatment. Electromagnetic waves, on the other hand, are high-energy waves whose frequencies can have adverse effects on the body. So magnets are not harmful to the human body.
Magnet bracelets are neither good for the human body. There are nuclear magnetic fields in medical equipment, and the high magnetic field is above 3T, which is not harmful to the human body. It is generally accepted that among all radiology medical equipment, MRI is the most reliable. That is to say, people are not afraid of magnetic fields, but more afraid of rays.
High magnetic fields do have negative effects on the human body, but the magnet content in the magnet bracelet is limited, so it is impossible to have any effect on the human body. Some people claim that magnets provide magnetic force to change physiological tissues, and even think that each cell has positive and negative poles, and some people claim that magnets can improve blood circulation.
In fact, there is no evidence to prove that there is any interaction between human tissue cells or blood and magnetic fields. Iron ions in red blood cells are not only non-ferromagnetic, but even diamagnetic, and will not be attracted by magnetic fields. It is well known that hot compresses are good for the body. The result is that the skin turns red. If the magnets really promote blood circulation, why is there no redness on the skin that is in direct contact with the magnets?
The effect of magnetic therapy is only the so-called psychological suggestion ability, and there is no very direct and obvious medical effect. The magnet bracelet continuously stimulates the microcirculation system of the wrist through weak magnetic force lines, which has a very weak effect on improving the human body's physiological magnetic field and eliminating fatigue. It is indeed good for sleep, but not much. Wearing a magnet bracelet for a long time will not cause any damage to the human body.
