The School of Sport and Exercise Sciences at Liverpool John Moores University did a study on negative ions (which are released by ion bracelet bands) looking at heart rate, respiratory rate and body temperature, and found that the subjects had better balance when exposed to negative ions.
There are many different companies selling different versions of Ionic bracelets which are all tested by the output of negative ions released and looking at the results from an Ion tester there is one Ion Bracelet Companywhose bands have a negative ion output of 4000 per cm cubed called Infinity Pro which is a good output. They are based in the UK but sell band worldwide.
