Scientist might of found a way to relive stress you feel physically on your body by just crossing your arms. Giandomenico Lannetti at University of London gave 20 volunteers a test to see how physical pain could be eased. The volunteers would take a series of painful stabs onto the back of their hands with a laser. Each pulse would take 8 to 12 seconds each series. After being stung by the laser half of the volenters would sit with their palms flat on a desk and the other half would cross their arms. Volenteers would have to measure on a scale from 0 to 100 on the pain. People who had crossed their hands had less pain then the people who had kept their palms face down on a desk. Lannetti thinks that if you place your hands in a unfamiliar position, it will relieve your pain by your brain knowing your body frame is in a unfamiliar position.
I chose to write about this article because I think its interesting how scientists are always trying to help the human body. If scientist can find a way how to relieve physical pain it could help many people who get cut or injured physically. Next time i get hurt I am going to cross my arms and see if it helps because I can test Lanetti's theory. This article makes me think about how if you could relieve pain by yourself, i wonder how else you could help your body by just moving body parts to make your brain think something else. I would recommend this article to any scientist who is also working on something like like Lannetti's theory.
