Long time contact magnet, will be harmful to the body?

Magnets are not invented by people, they are natural magnetite. The ancient Greeks and Chinese discovered a natural magnetized stone in nature and called it "magnet". This stone can magically suck up small pieces of iron and always point in the same direction after swinging at will. Early navigators used this magnet as their earliest compass to identify directions at sea. The earliest discovery and use of magnets should be the Chinese, that is, the use of magnets to make a "compass", is one of China's four great inventions. After thousands of years of development, today magnets have become a powerful material in our lives. By synthesizing alloys of different materials, it is possible to achieve and absorb.

After thousands of years of development, today magnets have become a powerful material in our lives. By synthesizing alloys of different materials, the same effect as the magnet can be achieved, and the magnetic force can also be improved.

InMan-made magnets appeared in the 18th century, but the process of making stronger magnetic materials was slow until the 1920 s when Alnico was made. Subsequently, ferrites (Ferrite) were manufactured in the 1950 s, and rare earth magnets [Rare Earth magnet including neodymium iron boron (NdFeB) and samarium cobalt (SmCo)] were manufactured in the 1970 s. So far, magnetic science and technology has been rapid development, strong magnetic materials also make components more miniaturized.

The Earth itself has a very strong magnetic field.Therefore, people themselves have a kind of adaptation and even dependence on magnetism. The weaker stable magnetic field is good for the body, and magnetic therapy is often used in medical treatment. Electromagnetic waves are different, it is a high-energy wave, its frequency will have a bad effect on the body. So magnets are not harmful to the human body.

Magnet bracelets are neither harmful nor beneficial to the human body. Medical equipment has nuclear magnetic, high magnetic field hasMore than 3T, no harm to the human body. It is generally accepted that MRI is the safest of all radiology medical equipment. That is to say, people are not afraid of magnetic field, more afraid of rays. The high magnetic field does have a certain negative impact on the human body, but the magnet content in the magnet bracelet is limited, and it is impossible to cause any impact on the human body. Some people claim that magnets provide the magnetic force that changes physiological tissues, and even 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. The iron ions in red blood cells are not only ferromagnetic, but even diamagnetic, and will not be attracted by magnetic fields. It is well known that hot compress will promote blood circulation. As a result, the skin will turn red. If magnets can really promote blood circulation, why is there no redness in the skin directly contacted with 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 wrist microcirculation system through the weak magnetic field lines, which has a very weak effect on promoting blood circulation, improving the physiological magnetic field of the human body, and eliminating fatigue. It does have certain benefits for sleep, but not much. Long-term wear magnet bracelet and will not have any damage to the human body.

But if the magnetic field strength of the magnet is very strong. Generally moreMagnets with more than 3000 magnetic field strength are harmful to the human body. Below this standard, the harm to the human body is minimal.

Magnetic field penetration will harm the central nervous system, cardiovascular system, etc., and has an important impact on biological growth, life activities and behavior habits.
