On the advantages and disadvantages of magnets to human body.
Benefits:

1. According to the measurement, the heart, lungs, brain, muscles and nerves of human body have different degrees of micro-magnetic field. However, due to the changes in the earth's environment, the accelerated pace of life, mental stress and other factors, it is inevitable that some people's own magnetic fields will be disordered. However, scientific research has found that the use of complementary magnetic physiotherapy can prevent diseases and play a role in health care.

The earth is a big magnet, and human beings are not affected by the geomagnetic field all the time. Geomagnetism, like air, water and sunlight, is one of the indispensable elements for human survival. Under the action of magnetic field, people form their own magnetic field.

3. The human body receives the magnetic field through the skin, nerves, gastrointestinal tract and bone joints, which produces a certain curative effect, but the general curative effect is short-lived, and it is easy to hurt the gas, so it is not suitable for long-term use.

Disadvantages:

Whether the magnetic field is harmful to human body depends on its strength. Generally speaking, magnets below 3000 gauss (magnetic field unit) are harmless to human body, and magnets above 3000 are harmful to human body. Although magnets are harmful to human body, they can be ignored. Some people are afraid that the magnetic field will affect the human body, but according to the test, the influence of the magnetic field on people is only one-fifth of that of TV.

There is no difference in wearing time, and you can wear it at any time.

Extended data:

People with metal foreign bodies such as stents and pacemakers should avoid using "the intensity and time of magnetic therapy vary according to the disease and condition." Ouyang Qi and Bi Sheng emphasized that magnetic therapy should vary from person to person due to illness, and should never be applied across the board.

Clinically, the intensity of magnetic therapy can be divided into small, medium and large. The magnetic field intensity below1000 mt is small, and it is generally used to soothe the nerves, improve insomnia and treat early heart disease. The magnetic field intensity of1000 mt to 300mT is moderate, and it is most commonly used to treat surgical diseases such as sprain.

300mT to 600mT is a high-intensity magnetic field, which is used to shrink tumors in hospitals, but most hospitals will not reach this intensity. Moreover, the doctor will adjust the magnetic field size and use time according to the patient's curative effect and response. So it is unscientific to use a numerical magnetic field at home for a long time.

Magnets-Baidu Encyclopedia seems to cure all diseases, most of which are psychological effects, and home magnetic therapy has little effect.
