Magnetic Therapy: Attractive or Repellent?

Hi, Marguerite here.
Just wanted to let my faithful readers know that Painreliever.com has gotten in a new line of magnetic products. They’re from Dr. Bakst Magnetics, and include magnetic bracelets, magnetic insoles, a magnetic mattress pad, a magnetic wrist brace, and more.
I have to confess, I’m a little skeptical about magnetic therapy. But I also know that a great deal of people, for a very long time, have sworn by it.
I can understand why they would–after all, most physicists and biologists say that humans and animals are run on electric signals humming through our bodies. Electricity carries messages between cells. One of those messages would be pain, right? We all know that magnets and electricity are interdependent. In fact, moving magnets can produce an electrical current. And changes in electrical currents can produce a magnetic effect. So perhaps magnetic therapy might work by interrupting the electrical signal of pain–or the symptom that is causing the pain.
Some advocates of magnetic therapy claim that therapeutic magnets have an effect on red blood cells. On the surface, this claim is logical as we all know that red blood cells contain iron–and iron reacts to magnets, right?
Yes, but–
The iron in your body is found in chemical compositions that are not ferromagnetic. Iron is ferromagnetic in bulk quantities–and when I say bulk quantities, I mean compared to what is found inside a red blood cell, which is 8 millionths of a meter in diameter. You would need over a thousand red blood cells to make a line one centimeter long. And even then, if you held a magnet over these blood cells, nothing would happen.
However, there is research being conducted that have made skeptics cautious about sweeping dismissals of magnetic therapy. Studies involving the effect of magnet therapy on fibromyalgia, diabetic peripheral neuropathy, depression, and wound healing have turned up results that say more research is needed.
So, I’m not going to say no to magnetics. I wouldn’t recommend magnetic therapy as a replacement for more conventional treatments. But my jury is still out on the subject as a whole. I know scientists are still discovering wonderful things about the world and about our bodies.
