When sleeping at night, a magnet is placed under the pillow, which has a peculiar effect of preventing insomnia.

The principle of magnetic therapy? Physical magnetic supplement

The earth is a big magnet, and human beings are always affected by the geomagnetic field. 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. According to 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, some people's own magnetic fields are inevitably disordered. However, scientific research has found that the use of complementary magnetic physiotherapy can prevent diseases and play a role in health care.

Applying a magnetic field with a certain intensity to the affected part or related acupoints can relieve some pains, such as acute sprain and contusion, lumbar muscle strain, nervous headache and some arthritis. This is the so-called magnetic therapy, referred to as magnetic therapy.

In traditional medicine in China, magnets have long been used to treat diseases. Theoretically speaking, magnets can tonify kidney, absorb qi, subdue yang and soothe the nerves. Magnetite re-entering the kidney can cure asthma due to kidney deficiency, absorb latent yang, communicate with the heart and kidney, and treat insomnia and fright. The human body receives the magnetic field through the skin, nerves, gastrointestinal tract and bone joints, which has a certain curative effect, but the general curative effect is short-lived, which is easy to hurt gas and should not be used for a long time.

China is the first country in the world to discover and apply the magnetism of matter, and the use of magnetic field to treat diseases can be traced back more than 2,000 years ago. According to Records of the Historian, some people used magnets to treat diseases in the early Western Han Dynasty, but due to the limitation of historical conditions, the use of magnetic fields to treat diseases was relatively limited and developed slowly. In recent ten years, China's magnetic therapy has developed rapidly and achieved good results in clinical application, experimental research and mechanism discussion.

Expert opinion: Buy carefully.

Nowadays, magnetotherapy health care products have been accepted by consumers. However, medical experts in Harbin, Heilongjiang remind people that there are still some misunderstandings in magnetic therapy, and it is best to consult a doctor before using it.

According to experts, there are many items with magnetic therapy and health care function on the market at present, and most of them are permanent magnets. Due to the lack of unified management and industry standards, there is an excessive exaggeration of curative effect. At present, the concept of magnetic therapy is misleading to many people. Magnetic pillow, magnetic necklace and other local magnetic therapy health products have the functions of tonifying kidney, nourishing essence, calming the liver and suppressing yang, calming the nerves and improving intelligence, and are suitable for dizziness, insomnia, dreaminess and other symptoms caused by deficiency of kidney qi and hyperactivity of liver yang. It has certain effects of calming, lowering blood pressure and regulating nerve function on magnetic objects acting on the whole body, such as magnetic bedding and magnetic mattress. However, the magnetic field intensity of this kind of products is quite large, which is several times of the geomagnetic field. There are many inferior products, so we must be careful when using them for a long time. If the symptoms of patients with physical weakness and neurasthenia get worse after use, or even have severe headaches, night sweats and other symptoms, they should stop using them. Therefore, it is best to consult a doctor before using magnetotherapy health care products.

For magnetic health care products, experts also reminded that it is forbidden to use pacemakers implanted in the body; There are metal foreign bodies in the body, such as metal fixing needles and shrapnel, which should also be used less or not; Pregnant women should try not to use magnetic supplies, so as not to affect the development of the fetus and baby.

Consumer tips? Carefully selected

The author visited the physiotherapy departments of several hospitals and the counters of magnetotherapy products in several major shopping malls to provide some practical suggestions for readers who want to buy magnetotherapy health products.

There are basically no magnetic health products sold in the physiotherapy departments of several big hospitals. According to the doctor, the use of magnetic field for disease prevention and health care does have scientific basis, but the requirements for magnetic health care products are also very high. Because it is difficult to master the intensity of magnetic fields with different intensities according to different conditions of human body.

In addition, magnetic health care products are closely related to personal habits and human behavior, and not everyone can feel comfortable when using them, so it needs to be considered comprehensively when purchasing. I met a lady in Cuiwei Mansion and 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 returned it, but both the salesman and the manager stressed that there was no quality problem and she would not return it. The lady felt very embarrassed. To avoid this situation, we must "think twice before you act".

Generally speaking, the following points should be paid attention to when purchasing magnetic health care products:

First, the choice of products with legal procedures and patents shows that they have been approved by the competent state departments.

Second, buy matching products, because when the products leave the factory, manufacturers have strict requirements on the size, polarity, maximum magnetic benefit and safety of the magnetic field, and they are not randomly combined.

Thirdly, try to choose the alloy magnetism of rare earth materials because it is relatively stable and difficult to demagnetize.

The fourth is to choose brand products. graduated shade

Magnetic therapy products: a wide variety.

Magnetic therapy health care products are divided into static magnetic therapy and dynamic magnetic therapy according to types. Static magnetotherapy instruments commonly include magnetotherapy earrings, magnetotherapy necklaces, magnetotherapy glasses, magnetotherapy vests, magnetotherapy underwear, magnetotherapy shoes, magnetotherapy fitness balls, magnetotherapy pillows, magnetotherapy kneepads, magnetotherapy trousers, magnetotherapy belts, magnetotherapy water cups, flexible magnetic sheets, etc. Dynamic magnetic therapy refers to the rotating magnetic field generated by magnetic therapy equipment, so as to achieve the purpose of treating diseases, such as field effect therapeutic apparatus.

At present, most of the magnetotherapy products on the market contain magnets, the main component of which is ferroferric oxide, and also contains metals such as manganese, magnesium and aluminum, which can form a large number of magnetic fields. High-quality products can also produce good magnetic effect and magnetize some substances. For example, after water is magnetized, the hardness can be reduced to soft water, the oxygen content can be increased, and the solubility of organic matter can be increased, which is helpful for digestion and absorption.
