Is it good for the body to wear a magnet on the wrist for a long time?

Are magnets really good for human health?

Any substance has strong or weak magnetism, and organisms are no exception General organisms have weak magnetism In addition, the physiological activities of organisms also produce magnetic fields, and these biological magnetic fields are very weak For example, the beating of a normal person's heart produces a cardiac magnetic field of about 10 10t; The neural activity of the brain produces a brain magnetic field of about 5 10 13 t They are much lower than the geomagnetic field near the ground (about 5 10 5 t) But due to the development of magnetic measurement technology, these weak biomagnetic fields can be measured, which is of great significance for studying the life activities of organisms.

After the lesion of the organism, its magnetic properties are different from the magnetism of normal organisms, and the magnetic field generated will also change These very small changes can be used for pathological research and disease diagnosis For example, similar to electrocardiogram and electroencephalogram commonly used in medicine, people are trying magnetocardiogram, magnetoencephalography and other human magnetogram technology to diagnose the condition of related parts Compared with human magnetogram technology and electrocardiogram technology, it has the advantages of no need to contact with the human body, large amount of measurement information, and high resolution At present, The diagnostic rate of using magnetocardiography to diagnose heart disease is already higher than that of electrocardiogram.

Long-term studies have found that many organisms are affected by the external magnetic field and change their growth, life activities and behavioral habits For example, in paleontological research, it has been observed that when the geomagnetic field is weakened, some organisms on the earth are greatly reduced, and even extinct The pigeon's ability to "recognize home" is related to the geomagnetic field The eggs or larvae of fruit flies are placed in an uneven strong magnetic field for a period of time, and experiments have found that the magnetic field has an impact on the development, morphology and reproductive ability of fruit flies

The influence of magnetic field on biology also has important applications in medicine The use of magnets to treat diseases has been recorded in the "Historical Records" of the Western Han Dynasty in China Li Shizhen, a great pharmacist in the Ming Dynasty of China, in his pharmacological masterpiece "Compendium of Materia Medica", the use of magnets or magnet-based drugs ** disease names of more than 10 kinds, at present, magnetotherapy has achieved more significant curative effects in various diseases such as lumbar muscle injury and hemangioma

In agriculture, aquaculture, etc., magnetic fields also have important applications For example, the seeds of crops are treated with a magnetic field of appropriate strength, which can promote seed germination and seedling growth, and improve yields Raising some livestock and breeding fish with water treated by magnetic fields can enhance the disease resistance of livestock and the ability of fish to withstand harsh environments

It is precisely because of the close relationship between magnetism and biology that a marginal science has emerged - biomagnetism, which takes biomagnetism, biomagnetic field and the relationship between biological life activities and magnetic field as the research object.

It should have *** on the body.

The strength of the magnetic field is harmful if it is large, and harmless if it is small.

The magnetic field can regulate the biomagnetic field in the body, produce induced microcurrents, change the permeability of cell membranes, change the activity of certain enzymes, dilate blood vessels, and accelerate blood flow, so as to achieve analgesia, analgesia and other auxiliary effects. Smell.

If magnetotherapy products are used incorrectly, they can cause harm to the body. If the magnetic field strength is too low, it may not achieve the desired effect; Excessive magnetic field strength may have adverse effects on the human body, such as dizziness, vomiting and other magnetic fields, dizziness and other phenomena.

The strength of the magnetic field is harmful if it is large, and harmless if it is small.

Generally speaking, magnets below 3000 gauss (magnetic field units) are not harmful to the human body, and magnets with a magnetic field strength of more than 3000 are harmful to the human body. There is no difference in the wearing time, you can wear it whenever you want.

The intensity of magnetotherapy is small, medium, and large. The magnetic field strength below 100MT is small, and it is generally used to calm the nerves, improve insomnia and early heart disease**; 100mt to 300mt magnetic field strength is moderate, most commonly used for surgical conditions such as sprains**; 300MT to 600MT is a high-intensity magnetic field that is used by some hospitals to shrink tumors, but most hospitals do not reach this intensity.

Beneficial. Indications: liver yang vertigo, panic, insomnia, eye coma, tinnitus, deafness, kidney deficiency.

Magnets taste salty, flat taste, liver and kidneys; mass, and the decline of the town, has the effect of calming the liver, calming the ears, calming the eyes, absorbing breath and relieving asthma.

To make magnets, some materials can be rubbed together to form magnets, the material is either iron or steel, but not all steel can be made into magnets, let's make a magnet, a magnet and a screwdriver are what you need, which magnet, rub the metal part of the screwdriver, from one end to the other, rub it over and over again, and make a magnetic screwdriver.

It depends on whether it is strong or weak, and no one brings a fast magnet, it is a processed chain or pendant, which is good for the body.

It's better not to, there is already a lot of radiation around us.
