The belief that magnets increase blood flow is repeated so often, it’s almost established dogma! But read on and see what the evidence says.
From our perspective, the therapeutic effect of quadrapolar and other multipolar magnets results from how they interact with the nervous system and in particular on unmyelinated C-fibres and not necessarily on increasing blood flow. See how Q magnets work for more information.
We have always been dubious about claims of increased blood flow and have to work hard to not repeat it ourselves.
