Does Wearing Magnetic Jewelry Improve Blood Flow?

It probably does in two ways. First it enlarges the very small capilliaries, thus allowing more blood to flow through them.

Then the red blood corpuscles line up all in the same direction when under the influence of a therapeutic magnet, and this probably helps with a smoother flow of blood too.

When you have an injury, beter blood flow is almost certainly good news in helping it to heal faster.
