Copper bracelets are an ancient fashion item and were worn on the wrist, they are also believed to help ease the aches and pains of stiff and sore joints. Proponents of the treatment suggest that the skin absorbs tiny particles of copper. This is then said to help reduce inflammation in the joints, as copper is a vital nutrient that serves this purpose in the body, however the British NHS disputes this, even though copper is vital to life as it is present in the human body in trace amounts.
It helps the body use iron and supports nerve function. According to the Copper Development Association, copper is essential for the following bodily functions like skin pigmentation, energy production, iron utilisation, nerve function and enzyme systems. It is also found in many foods like chocolate, beef liver, nuts, potatoes, green vegetables and shellfish.
Copper was one of the first metals ever used by humans mostly for jewellery, tools, coins, vessels (including pots and pans), weapons (including bullets which sometimes use brass) and is a very good conductor of electricity - hence it's use in many electronic devices, motors, alternators and components and particularly in wires, cables and integrated-circuit inter-connections - although many of those are now made from gold.
It is non-ferrous which means it isn't attracted to a magnetic field (which can make the term Magnetic Copper Bracelet a bit confusing), however it can be used in magnetic levitation if used near an alternating magnetic field.
