Are magnets harmful to the body?

Magnet is a natural stone that has a strong ability to absorb iron. However, magnet has another function that many people don’t know. Magnet is actually a very famous Chinese medicinal material. Magnets are used in many traditional Chinese medicines to treat human diseases, and now there is a type of underwear called magnetic underwear. Some people are worried that magnets will cause harm to the human body. So, are magnets really harmful to the human body?

1. Are magnets harmful to the body?

It is true that magnets with weak magnetic fields have some therapeutic effects on humans, but improper use will definitely have side effects. Magnets with strong magnetic fields will definitely not work on humans for a long time, as they will disrupt the body's original magnetic field.

2. Are magnetic underwear harmful to the body?

Magnetic therapy underwear usually has magnets of a certain strength added to the lining of the underwear, which produce analgesic effects through the intensity of the magnetic field. It is not the case that the stronger the magnetic force, the better. Scientific experiments show that the best magnetic field strength for the human body is 800-1100Gs. This strength has little effect on small fish. If the strength is greater than this, it will be harmful to the human body. Therefore, when purchasing magnetic therapy underwear, pay attention to the magnetic field strength marked on the underwear.

3. The origin of magnet

During the Spring and Autumn Period and the Warring States Period, the famous ancient Chinese doctor Bian Que tried to use magnet for treatment; in the early Western Han Dynasty, the book "Shennong's Herbal Classic" recorded the properties of magnet: it can treat diseases and pains. Magnet tastes pungent and cold, and is used to treat arthritis, rheumatism, swollen and painful limbs, etc. By the Ming Dynasty, Li Shizhen had mixed magnet powder with various ointments to make external medicines. In the Qing Dynasty, some people recommended and used magnets to treat sensorineural deafness and tinnitus.

4. What is magnetic therapy?

Under the influence of the earth's magnetic field, people form their own magnetic field accordingly. It has been measured that the human heart, lungs, brain, muscles and nerves all have micromagnetic fields to varying degrees. However, due to factors such as changes in the earth's environment, accelerated pace of life, and mental stress, it is inevitable that some people's magnetic fields become disordered.

Scientific research has found that the use of magnetic physical therapy can prevent diseases and play a role in health care. Applying a magnetic field of a certain intensity to the affected part of the human body or related meridian points can relieve some pains, such as acute sprain, lumbar muscle strain, neuralgia and certain arthritis. This is called magnetic therapy, or magnetic therapy for short.
