What are the therapeutic effects of magnetic therapy?

1. Analgesic effect Magnetic field has obvious analgesic effect. Dynamic magnetic field relieves pain faster, but not consolidated; constant magnetic field relieves pain slower, but the pain relief time is longer. Magnetic therapy is often used to treat various pains, such as soft tissue injury pain, neuralgia, inflammatory pain, visceral organ pain and cancer pain. The analgesic effect of magnetic therapy varies in speed. Most patients can experience analgesic effect within a few minutes to 10 minutes after magnetic therapy. The mechanism of magnetic therapy analgesia may be multifaceted. Magnetic therapy improves microcirculation and tissue metabolism, thereby correcting pain caused by ischemia, hypoxia, edema, and accumulation of pain-causing substances; magnetic field can increase the activity of pain-causing substance hydrolases, so that bradykinin, histamine, 5-hydroxytryptamine and other pain-causing substances are hydrolyzed or converted; magnetic therapy also has the effect of reducing nerve excitability, etc.

2. Sedative effect Magnetic therapy can improve sleep state, relieve muscle spasms, reduce facial muscle spasms, relieve asthmatic bronchitis and pruritus, etc. This may be related to the effect of magnetic field on the nervous system. Chinese medicine magnet has the effects of calming the mind and calming the nerves, calming the liver and suppressing yang.

3. Detumescence effect The magnetic field has a significant anti-exudation effect, which has been confirmed in clinical and experimental studies. Experimental observations show that the magnetic field has the effect of reducing inflammatory substances (histamine, etc.) to increase vascular permeability, and can also accelerate the transfer of proteins from tissue gaps, indicating that the detumescence effect of the magnetic field is significantly related to its effect on permeability and colloid osmotic pressure. Magnetic therapy has a significant detumescence and analgesic effect on soft tissue injuries, traumatic hematomas, frostbite, burns, inflammation, etc.

4. Detumescence effect The magnetic field has a certain detumescence effect, which is related to the magnetic field improving microcirculation, detumescence, analgesia and promoting immune reactivity. The magnetic field has no obvious direct antibacterial effect.

5. Therapeutic effect on coronary heart disease and hypertension Low-intensity constant magnetic field (15-50mT) is used to treat patients with coronary heart disease or early hypertension. Most patients have improved general conditions after treatment, headaches, heart pain are reduced or disappeared, blood pressure drops, and pulse rate slows down. Some authors have proposed that low-frequency alternating magnetic fields (50Hz, 10-20mT) are more effective than constant magnetic fields in treating angina pectoris caused by coronary heart disease, but are ineffective against arrhythmias. Clinical and experimental data show that alternating magnetic fields have a good effect on heart pain syndrome, myocardial contractility, blood flow rheology, lipid metabolism, microcirculation, etc., but have no significant effect on the conduction system of the heart.

6. Effect on tumors Magnetic therapy has a certain effect on benign and malignant tumors, and can shrink or eliminate benign tumors such as fibroma, lipoma, capillary hemangioma, and ganglion cyst. It also has the effect of shrinking tumors and improving symptoms for malignant tumors. High-dose non-uniform magnetic fields have significant effects, and generally uniform magnetic fields are ineffective against malignant tumors. The mechanism of the effect of magnetic fields on tumors is still unclear.
