Among all kinds of health care devices, magnetic therapy products have always been magical and enduring.
From tens of yuan of magnetic therapy combs and magnetized cups to tens of thousands of yuan of magnetic therapy instruments and magnetic therapy beds, everything is available.
Just looking at these advertisements, I feel that magnetic therapy products are [cure diseases without diseases, strengthen the body without diseases] and can be used by anyone.
Is this really the case? Today, Dr. Clove will take a look with you.
Magnetic therapy improves blood circulation?
Opinions vary on the benefits of magnetic therapy, and the most widely circulated one is to improve blood circulation.
You see, an encyclopedia is written like this:
The source of this statement is probably:
The most important cells in human blood are red blood cells, which contain hemoglobin and hemoglobin contain iron, which will be affected by magnetic field, thus improving (accelerating) blood circulation and benefiting health.
However, this statement only seems reasonable.
The iron element in hemoglobin is very small and is scattered in individual hemoglobin, rather than arranged in blood vessels.
Under such conditions, the magnetic field strength generated by ordinary magnetic therapy products cannot attract red blood cells at all, so there is no way to change blood flow and promote blood circulation.
Some people may want to ask, is the [magnetic force] of magnetotherapy products not strong enough, and will a stronger magnetic field be effective?
Then let’s look at the most common [super magnetic product] nuclear magnetic resonance (MRI).
The unit of magnetic field is [Tesla], commonly used are milliTesla and micro Tesla. The so-called magnetic therapy bed has about tens to hundreds of milliTesla. The magnetic field strength of common 3 Tesla MRI is at least dozens or even hundreds of times that of magnetic therapy products.
Is this magnetic force what level? You can feel it through a picture:
However, the magnetic field of MRI is so strong that it has not been used by hospitals to improve the blood circulation of patients, so let alone those magnetic therapy products with weak magnetic field.
Can magnetic therapy cure diseases?
In fact, there is no evidence that magnetic therapy products can cure diseases.
Advertisements often have [experts] appearing to prove that magnetic therapy products are effective. In fact, the most reliable thing is not the opinions of a certain expert, but the diagnosis and treatment guidelines drawn up by gathering numerous clinical research results.
For example, lung cancer has guidelines for diagnosis and treatment of lung cancer and hypertension has guidelines for diagnosis and treatment of hypertension. These guidelines provide doctors with all strictly demonstrated treatment opinions.
However, the word “magnetotherapy” was not mentioned in all the medical guidelines in China, that is to say, magnetotherapy has never been recognized by the mainstream medical community in China.
In foreign countries, the reputation of magnetotherapy is even more smelly. Magnetotherapy is considered pseudoscience in the international mainstream medical field. However, magnetotherapy still has a large market because it involves the interests of enterprises and the psychological implications of years of publicity on people.
This is just like radiation-proof pregnant women’s clothing. Doctors and popular science organizations have repeated it countless times. This thing is a psychological comfort effect, but it still cannot stop its hot sales in China.
Some data show that the vast majority of [radiation protection clothing for pregnant women] in the world are sold to Chinese pregnant women.
Two methods to help you judge whether a product/therapy is reliable.
Ordinary people, especially the middle-aged and the elderly, are easily confused by the publicity of various health care products and health care devices, while various professional terms and high-end words on the product description make people dizzy.
In fact, there is no need for in-depth understanding. Judging these health care products or health care devices is unreliable. There are mainly two points:
1. Look at the approval number
As long as the product claims to be able to cure diseases, it must have the national approval number, for example, the product marked with [Chinese medicine standard word XXX XXX] can cure diseases.
Those who are worried about forging the approval number can go to China Food and Drug Administration’s official website for inquiries.
2. Look at the publicity effect
If a product does not have the standard name of Chinese medicine, it usually belongs to health care products or health care devices, and cannot be written with the effect of treating diseases according to regulations.
If these products mention [treating diabetes, hypertension and heart disease], they are all false propaganda.
How much more can we expect from an illegal product?
At the end of the day, if someone around you is stubborn about magnetotherapy products, you can forward the following news to them.
On July 19, 2017, the Inspection and Quarantine Bureau in Yantai, Shandong Province intercepted a batch of magnetic therapy health pads with serious radioactivity exceeding the standard.
After testing, the radiation measurement of these magnetic therapy health care pads has reached 255 times higher than the background value, and if they are closely contacted for a long time, the annual radiation dose is as high as 200 mSv.
200 mSv is a what concept?
We take a chest radiograph and receive about 0.1 mSv of radiation. If we spend one year with this magnetic therapy health care pad, it is basically equal to-
2,000 films were made free of charge.
