(1) Improve blood microcirculation:
This is one of the most important biological effects of the magnetic field on the human body. Under the action of the magnetic field, the function of microvessels changes, mainly manifested as dilation of microvessels, and the blood flow speed is accelerated; when the blood flow of the dilated blood vessels is stagnated, the magnetic field can constrict these blood vessels, and the stagnated blood flow becomes more fluid. , which indicates that magnetic field induction has a bidirectional regulatory effect on blood vessels.
(2) Adjusting blood pressure:
Magnetic field therapy is bidirectional in the adjustment of blood pressure, and the antihypertensive effect is particularly obvious.
It is generally believed that the pathogenesis of hypertension is related to strong external pathogenic factors, such as long-term mental overstress, mental trauma, etc., which make the cerebral cortex dysfunctional and cannot effectively regulate and control the subcortical vascular motor center. The vasoconstrictor function is often in a state of excitement and tension, causing spasm of small arteries, increased vascular tension, narrowing of vascular lumen, increased peripheral circulatory resistance, and increased blood pressure.
The magnetic field has a significant adjustment effect on the nervous system. It enhances the inhibition process of the cerebral cortex, relieves the spasm of the peripheral arterioles, dilates the arterioles, reduces the tension of the arterioles, lowers the blood pressure, and improves or disappears the symptoms.
(3) Analgesic effect:
The analgesic effect of magnetic therapy is obvious and rapid. Some people experience relief or disappearance of pain within minutes of the magnetic field being applied. Why does magnetic field have analgesic effect? Some people think that the magnetic field directly acts on the sensory nerves and reduces the excitability of the sensory nerves; some people explain that the magnetic field causes an analgesic substance called MEK (methionine encephalopeptide) in the body to increase and produce analgesic effect. Some scholars have also found that the magnetic field can inhibit the activity of pain-causing substances such as histamine, kinin, serotonin and acidic metabolites, and reduce the concentration of pain-causing substances to the level below the pain threshold to achieve analgesic effect.
Chinese medicine scholars believe that the analgesic effect produced by the magnetic field acting on the knocked down acupoints. It is also pointed out that the magnetic field has a good effect of reducing swelling, and the swelling is reduced or eliminated at the same time, and the sensory nerve endings are no longer compressed, and the pain is reduced or disappeared.
In a word, the analgesic effect of magnetic field has been affirmed in clinical application, and its analgesic mechanism is the result of the comprehensive effect of many aspects.
(4) Sedative effect:
The sedative effect of magnetic therapy is mainly manifested in promoting smooth falling asleep, increasing sleep time, and improving sleep quality. This is because the magnetic field has a regulating effect on the central nervous system. Experiments have shown that the high penetrating magnetic field can reduce the excitability of the central nervous system.
(5) Antispasmodic effect:
Animal experiments have shown that the magnetic field has the effect of relieving the spasm of intestinal smooth muscle. Therefore, it is commonly used in the treatment of patients with gastric cramps and intestinal spasms.
At the same time, because the magnetic field has the effect of enhancing the bidirectional regulation of intestinal activity, it also relieves the constipation. In addition, it is also effective for striated muscle spasms such as spasms or twitches of the legs and facial muscles.
(6) Anti-inflammatory effect:
The anti-inflammatory effect of magnetic field is not only effective for inflammation caused by various physical and chemical factors, but also effective for infections caused by certain biological factors. This is because: the magnetic field improves the local blood circulation of the lesion, so that antibodies, white blood cells and nutrients are quickly transported to the affected area, and the ischemia, hypoxia and acidity in the inflammatory area are improved and corrected. It can also promote the absorption and dissipation of inflammatory substances. The process of exudation in the local area of inflammation is reduced. Magnetic fields increase the body's immunity. After the magnetic field acts on the body, it can enhance the phagocytosis of white blood cells and improve the cellular immunity of the human body; at the same time, it increases the content of human immunoglobulin and complement, and enhances the humoral immunity, thereby enhancing the body's disease resistance and anti-inflammatory capabilities. Magnetic fields have an inhibitory effect on bacteria.
The physiotherapy department of Bethune International Peace Hospital applied gyromagnetic machine to treat 39 patients with local pain, and observed the changes of white blood cells before and after magnetic therapy. Select the pain point and Zusanli point, magnetic therapy once a day, 20 minutes each time, 12 times as a course of treatment. The white blood cells were tested before treatment, and the results showed that 22 cases had increased leukocytes, accounting for 56.4%. After treatment, the average increase was 1895/mm3;
(7) Swelling effect:
The swelling reduction effect produced by the magnetic field is rapid and significant. This is because the magnetic field can transfer the protein in the local tissue, reduce the osmotic pressure accordingly, and reduce the exudation of water in the blood vessels, so that the local area is no longer swollen; Swelling is obvious. In addition, under the action of the magnetic field, the local microcirculation is improved, which is also beneficial to the reduction or elimination of swelling. For the effect of magnetic field to eliminate hematoma, some people think that it is related to the ability of magnetic field to enhance the activity of fibrinase.
(8) Antidiarrheal effect:
A large number of clinical experiments have proved that the magnetic field has a good effect on diarrhea, and the stronger the magnetic field, the better the effect. This is because the magnetic field reduces intestinal peristalsis, can promote the absorption of water, electrolytes and other substances in the intestinal mucosa, and can reduce the exudation of blood vessels in the intestinal mucosa; some people believe that it is related to the effect of the magnetic field on the meridian and acupoints - regulating the body's physiological function related.
(9) hypolipidemic effect:
Some people abroad used magnetic therapy to treat rabbits with hyperlipidemia, and found that the blood lipids of the rabbits decreased significantly. After stopping the treatment, they continued to feed the rabbits with high cholesterol feed, and the effect of lowering blood lipids could last for several weeks. Chinese clinicians use magnetic therapy to treat hyperlipidemia, and as a result, most of the patients' serum cholesterol, triglyceride, and low-density lipoprotein have significantly decreased. The lipid-lowering effect of magnetic therapy can be stably maintained for 1-16 months, and can be extended to 2-3 months if combined with physical exercise and diet therapy. The mechanism of magnetic therapy to lower blood lipids, some people think that it may be related to the adjustment of the activity of some lipid metabolism enzymes and the promotion of fat decomposition. It has also been speculated that magnetic fields can alter the molecular makeup of cholesterol so that it does not deposit easily on the walls of blood vessels, thereby preventing the formation of atherosclerosis.
(10) Anti-aging effect:
There are many factors affecting human aging. In addition to social, economic, psychological, environmental, etc., in terms of human metabolic process, magnetic field therapy can play an anti-aging effect from the following three aspects. Magnetic therapy can increase the content of sod (superoxide dismutase) in serum and reduce the content of aging factor lpo (lipid peroxide). Thereby, the free radical content of the human body is reduced, and the antioxidant defense ability is enhanced. In addition, the magnetic field also increases the lipid fluidity of the erythrocyte membrane in vivo, reduces the hemolysis, protects the integrity of the cell membrane, and exhibits anti-aging effects. Stabilize the hydrophilicity of human proteins. The material basis of human life is protein, and life aging is ultimately protein aging. The surface of the protein is charged, and due to the repulsion of the same sex, the proteins cannot stick together, forming a very stable hydrophilic colloid. Magnetic field therapy can stabilize the hydrophilicity of proteins, thereby preventing protein aging. When the magnetic field acts on the body, it can change the speed of the body's biochemical reaction and increase the content of the reaction products, so that the aging body can slow down or stop the biochemical reaction back to normal.
