Some practitioners have theorized that magnet therapy may improve circulation, increase blood oxygen, alkalize bodily fluids, decrease deposition of toxic materials in blood vessel walls or relax blood vessels through effects on cellular calcium channels. Other theories describe altered nerve impulses, reduced edema, increased endorphins, muscle relaxation, cell membrane effects or stimulation of acupoints. Some traditional Chinese medicine practitioners suggest that magnets may affect patterns of flow of the body’s life force, or qi. Scientists have studied magnet therapy for diabetic pain relief, fibromyalgia, multiple sclerosis, muscle soreness, osteoarthritis and other conditions.
