As a kid we have a feeling, that our world is safe, everything is settled and finished. We are learning so many things in school that are seem to be never changeable. History, sciences, mathematics.. everything is already invented.
As we grow up borders become more and more soft, and suddenly something completely new breaks into your cognition. This experience makes you rethink the word „certain”. Imagine, you are a doctor learning and practicing since decades. Of course it is not easy to accept changes, and it is also their duty to be skeptical. That might cause that medical science is still not convinced about what to think of magnetic therapy. Time to time new studies are made on both sides.
You can read about test made by the University of Virginia here, and make your own opinion. One thing is for sure, there are no studies stating that magnetic therapy may cause any harm, but tones of people saying the opposite. Maybe it is time to open our mind for those changes?
The researchers first found evidence to support this claim through research with laboratory rats. In their initial study, magnets of 70 milliTesla (mT) field strength—about 10 times the strength of the common refrigerator variety—were placed near the rat’s blood vessels. Quantitative measurements of blood vessel diameter were taken both before and after exposure to the static magnetic fields—the force created by the magnets. Morris and Skalak found that the force had a significant effect: the vessels that had been dilated constricted, and the constricted vessels dilated, implying that the magnetic field could induce vessel relaxation in tissues with constrained blood supply, ultimately increasing blood flow.
