According to researchers in the U.K., reducing pain can be as simple as crossing your arms across the middle of your body. Researchers believe that this position confuses the brain helping to reduce the intensity of pain. It's believed the brain has internal mappings for both the body and the external space outside the body that are usually activated together. The act of crossing the arms across the middle of the body interrupts the traditional mappings and as a result appears to lessen perceived stimuli such as pain. It should be noted that some of the most common chiropractic treatments, most specifically the chiropractic adjustment, also similarly affects the nervous system in a pain reducing manner.
