Magnet bracelets are neither harmful nor beneficial to the human body. There are nuclear magnets in medical equipment, and those with high magnetic fields above 3T are not harmful to the human body. It is generally accepted that among all radiology medical equipment, MRI is the safest. In other words, people are not afraid of magnetic fields, but more afraid of rays. High magnetic fields do have a certain negative impact on the human body, but the magnet content in the magnet bracelet is limited and it is impossible to have any impact on the human body. Some people claim that magnets provide the magnetic force to change physiological tissues, and even believe that every cell has positive and negative poles. Others claim that magnets can improve blood circulation. In fact, there is no evidence that human tissue cells or blood have any interaction with magnetic fields. The iron ions in red blood cells are not only non-ferromagnetic, but are even diamagnetic and will not be attracted by magnetic fields. It is known that hot compresses can promote blood circulation. The result is that the skin will turn red. If magnets can really promote blood circulation, why is there no redness in the skin that is in direct contact with the magnets?
The effect of magnetic therapy is only the so-called psychological suggestion ability, and has no very direct and obvious medical effect. The magnet bracelet continuously stimulates the microcirculatory system of the wrist through weak magnetic lines, which has a very weak effect on promoting blood circulation, improving the human body's physiological magnetic field, and eliminating fatigue. It does have certain benefits for sleep, but not much. Wearing a magnet bracelet for a long time will not cause any harm to the human body.
