People can raise their pain threshold by altering brain chemistry, study in arthritis patients shows

The numbers of opiate receptors in the brain increases to combat severe pain in arthritis sufferers, researchers have shown for the first time. By applying heat to the skin using a laser stimulator, the researchers showed that the more opiate receptors there are in the brain, the higher the ability to withstand the pain.
