It ’ s been known for a long time that a magnetic field influences the human body. It activates the molecules, widens the blood vessels, thus intensifying blood flow, quickens the cellular metabolism, lowers blood coagulation, facilitates oxygen intake and lowers pain levels. Electromagnetic field has three parameters: induction, frequency and intensity of electric field. That ’ s what makes some fields dangerous to man and some – with frequency lower than 50 Hz, therapeutic. The factor that decides on the effect of therapy is finding the right frequency. Various works on magnetic field therapy shows its beneficial influence on many ailments. It ’ s been demonstrated that a low-frequency magnetic field (20 – 40 Hz) triggers a natural anesthetic cascade in the nervous system, due to heightened beta-endorphins production.
