What are the advantages and disadvantages of magnets and magnets on the human body?

◆Magnet Hypnosis

When sleeping at night, placing a magnet under the pillow has a unique effect in preventing insomnia.

Principle of magnetic therapy? Physical magnetization

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 life to survive. Under the influence of the magnetic field, people form their own magnetic field accordingly. According to measurements, the human body's heart, lungs, brain, muscles and nerves have varying degrees of micromagnetic fields. However, due to factors such as changes in the earth's environment, accelerated pace of life, and mental stress, some people's own magnetic field is inevitably disordered. Scientific research has found that the use of magnetic 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 diseases, such as acute sprains and contusions, lumbar muscle strains, neurological headaches and certain arthritis. This is called magnetic therapy. , referred to as magnetic therapy.

In the traditional medicine of the motherland, magnets have long been used to treat diseases. According to the theory of traditional Chinese medicine, magnets can nourish the kidneys and absorb qi, subdue yang and calm convulsions. The magnet substance reenters the kidneys and can cure kidney deficiency and asthma. It can also absorb latent yang and communicate with the heart and kidneys to treat insomnia, palpitation and other diseases. The human body receives the magnetic field effect through the skin, nerves, gastrointestinal tract, and bones and joints, which produces a certain curative effect. However, the general curative effect is short-lived and can easily damage Qi, so it should not be used for a long time.

my country is the first country in the world to discover and apply material magnetism. The use of magnetic fields to treat diseases can be traced back to more than 2,000 years ago. According to "Historical Records", in the early Western Han Dynasty, some people used magnets to treat diseases. However, due to limitations of historical conditions, the use of magnetic fields to treat diseases was relatively limited and developed slowly. In the past ten years, magnetic therapy has developed rapidly in my country, and has achieved good results in clinical application, experimental research, and mechanism exploration.

Expert opinion: Buy with caution

Nowadays, magnetic therapy health care products have been accepted by consumers. However, medical experts from Harbin City, Heilongjiang Province, remind people that there are still misunderstandings about magnetic therapy, and it is best to seek the advice of a doctor before using it.

According to experts, there are many products on the market that have magnetic health care functions, and most of them are permanent magnets. Due to the lack of unified management and industry standards, there is a phenomenon of over-exaggerating the efficacy, and the current concept of magnetic therapy has a certain misleading effect on many people. Local magnetic therapy health products, such as magnet pillows and magnetic necklaces, can nourish the kidneys and essence, calm the liver and subdue yang, soothe the mind and improve intelligence. They are suitable for symptoms such as dizziness, insomnia and dreaminess caused by kidney qi deficiency and liver yang hyperactivity; Magnetic products that affect the whole body, such as magnetic bedding, magnetic mattresses, etc., have a certain effect of calming, lowering blood pressure and regulating nerve function. However, the magnetic field strength of this kind of products is relatively large, several times that of the earth's magnetism. Moreover, there are many inferior products, so long-term use must be done with caution. If the symptoms of patients with physical weakness or neurasthenia worsen after use, or even severe headaches, night sweats and other symptoms, use should be stopped. Therefore, it is best to seek the advice of a doctor before using magnetic therapy supplements.

As for magnetic therapy health care products, experts also remind that those with pacemakers implanted in their bodies are prohibited from using them; if there are metal foreign objects in the body, such as metal fixation pins, shrapnel, etc., they should also be used sparingly or not; pregnant women Pregnant women should try not to use magnetic products to avoid affecting the development of the fetus and baby.

Consumption Tips? Choose carefully

The author visited the physical therapy departments of several hospitals and the magnetic therapy product counters in several major shopping malls to provide guidance for those who want to purchase magnetic therapy health care products. readers offer some practical suggestions.

The physical therapy departments of several large hospitals basically do not have various magnetic health care products on the market. According to doctors, there is indeed a scientific basis for using magnetic fields for disease prevention and health care, but the requirements for magnetic health care products are also very high. Because magnetic fields of different strengths should be used for different conditions of the human body, but this strength is difficult to control.

In addition, magnetic health care products are closely related to personal living habits and human body behavior. Not everyone will feel comfortable using them, so you need to consider carefully when purchasing them.

The author met a woman in Cuiwei Building. She bought a magnetic therapy pillow the day before. When she used it that night, she felt that the pillow was too high and uncomfortable, so she came to return it. However, the salesperson and manager both emphasized that there would be no return unless there was a quality problem. The woman felt that the pillow was too high and uncomfortable. Very difficult. To avoid this happening, it is still necessary to “think twice before buying”.

Generally, when purchasing magnetic health products, you should pay attention to the following points:

First, choose products with legal procedures and patents, indicating that they have been approved by the national competent authority.

The second is to purchase supporting products, because when the product leaves the factory, the manufacturer has strict requirements on the size, polarity, maximum magnetic efficiency and safety of the magnetic field, and they cannot be combined randomly.

Third, try to choose alloy magnets made of rare earth materials as materials, because they have good stability and are not easy to demagnetize.

The fourth is to choose brand products. Wenyun

Magnetic therapy products: various varieties

Magnetic therapy health care products are divided into static magnetic therapy and dynamic magnetic therapy according to their types. Common static magnetic therapy equipment include magnetic therapy earrings, magnetic therapy necklaces, magnetic therapy glasses, magnetic therapy vests, magnetic therapy underwear, magnetic therapy shoes, magnetic therapy fitness balls, magnetic therapy pillows, magnetic therapy knee pads, magnetic therapy pants, magnetic therapy Belts, magnetic therapy water cups and more flexible magnetic sheets, etc. Dynamic magnetic therapy refers to magnetic therapy equipment that generates a rotating magnetic field to achieve the purpose of treating diseases, such as field effect therapy devices.

Most of the magnetic therapy products currently on the market contain magnets, whose main component is ferroferric oxide. It also contains manganese, magnesium, aluminum and other metals, which can form a large amount of magnetic field. High-quality products can also produce good magnetization effects and magnetize certain substances. For example, after water is magnetized, the hardness can be reduced and the water becomes softer. The oxygen content can be increased, and the solubility of organic matter can be increased, thus helping digestion and absorption.
