I remember as a kid always thinking it was the ageing hippy types that wore this kind of shit as basically it was and there was absolutely no benefit apart from the placebo effect which possibly works if you do genuinely believe it works or are open minded about the possibility of it working.
I'm a sceptic and so was my Dad, in fact he was probably the worlds biggest sceptic ever however he did have a few ailments in his last 20-25 years that he couldn't pin on any specific cause.
He did suspect that it may have been partly down to having breathed in all manner of dust including (unknown to him at the time) dust containing heavy metals and also working with various other hazardous materials long before H&S was top priority
Even as a massive sceptic he did try wearing a copper bracelet, i'm not sure if it did him any good or if he thought it did him any good but remember him saying it wouldn't do him any harm so it was worth trying, realistically my dad must have been at a point of being willing to give anything a go to relieve the symptoms
So it won't do any harm, apart from looking like a twat obviously
