Magnetic therapy

I don't know anything about this but on other cleanse forums it is advised not to use jewelry or metals on the body because the body absorbs metal.
I read somewhere that the soft martial arts like tai chi or Qi gong don't believe in using jewelry or watches because the body has its own center of gravity. Metal interferes with it.
So I think magnetic therapy is not a good idea.
I would like a response on this subject. Tweet
