the program said magnetic therapists claim their method works coz the magnets influence bloodflow into vital areas by attracting the iron in the blood.
actually, magnethotherapy does NOT work this way.
the basic componenets of blood are the red blood cells that transport oxygen the whole body, the white blood cells that fight the bacteria, platelets that clot up the blood in wounds aka natural healing power of the body and the +ve and -ve ions that are the static energy that enable us to walk,jump,run etc.
when a medical magnet is placed near our body, the magnetic flux from the medical magnet charge up the +ve and -ve ions inside our body and cause them to be very vibrant. the vibrant ions cause a stir in blood and hence blood is able to flow to parts of the body with greater ease. when this happens, blood circulation is improved.
when blood circulation is enhanced, more oxygen, anti-bacteria, natural healing power and energy are transported to parts of the body. the body is then able to function much better than before and thus becomes healthier.
this is how magnethotherapy works and helps in promoting better health.
