Magnetic bracelet is harmless and beneficial to human body. There is nuclear magnetism in medical equipment, and the high magnetic field is more than 3T, which is harmless to human body. It is recognized that nuclear magnetic resonance is the safest of all medical equipment in radiology department. In other words, people are not afraid of magnetic fields, but even more afraid of rays. High magnetic field does have some negative effects on human body, but the content of magnets in the magnet bracelet is limited, so it is impossible to have any impact on human body. Some people claim that magnets provide magnetic force to change physiological tissues, and even think that every cell has positive and negative poles, while others claim that magnets can improve blood circulation. In fact, there is no evidence that there is any interaction between human tissues and cells or between blood and magnetic fields. Iron ions in red blood cells are not ferromagnetic or even diamagnetic, and will not be attracted by magnetic fields. As we all know, hot compress can promote blood circulation, and as a result, the skin will turn red. If magnets can really promote blood circulation, why doesn't the skin that comes into direct contact with magnets turn red?

The effect of magnetic therapy is only the so-called psychological suggestion ability, and there is no very direct and obvious medical effect. The magnetic bracelet constantly stimulates the wrist microcirculation system through weak magnetic field lines, which has a very weak effect on promoting blood circulation, improving human physiological magnetic field and eliminating fatigue. It's really good for sleep, but it's not big. Wearing a magnet bracelet for a long time will not do any harm to the human body.
