Magnet bracelets are neither harmful nor beneficial to the human body. There are nuclear magnets in medical equipment, and high magnetic fields of more than 3T are not harmful to the human body. It is recognized that in all radiology medical equipment, nuclear magnetic is the safest. In other words, people are not afraid of magnetic fields, but more afraid of rays. It is true that high magnetic fields have some negative effects on the human body, but the limited amount of magnets in magnet bracelets is not likely to have any effect on the human body at all. Some people claim that magnets provide the magnetic force to change physiological organization, and even believe that every cell has positive and negative poles, while others claim that magnets can enhance the circulation of blood. In fact, there is no evidence that the body's tissue cells or blood and magnetic fields have any interaction, the iron ions in red blood cells, not only no ferromagnetism, and even anti-magnetic, will not be attracted by the magnetic field, it is well known that hot packs will promote blood circulation, the result is that the skin will become red, if the magnet can really promote blood circulation, why is there no reddening of the skin in direct contact with the magnet?
The effect of magnetic therapy is only the so-called psychological suggestion ability, and there is no very direct and obvious medical effect. Magnet bracelet through the weak magnetic lines of force constantly stimulate the wrist microcirculation system, on the promotion of blood circulation, improve human physiological magnetic field, eliminate fatigue has a very weak effect, does have some benefits for sleep, but not much. Long-term wearing magnet bracelets does not cause any damage to the human body.
