Washington: A little over an hour of meditation produces powerful pain-relieving effects in the brain, a new study shows.
For the study, a group of healthy volunteers who had never meditated attended four, 20-minute classes to learn a meditation technique known as focused attention, according to a Wake Forest statement. Focused attention is a form of mindfulness meditation where people are taught to attend to the breath and let go of distracting thoughts and emotions. Both before and after meditation training, participants` brain activity was examined using a special type of imaging -- arterial spin labelling magnetic resonance imaging (ASL MRI) -- that captures longer duration brain processes, such as meditation, better than a standard MRI scan of brain function. During these scans, a pain-inducing heat device was placed on the participants` right legs. This device heated a small area of their skin to 120 degrees Fahrenheit, a temperature that most people find painful, over a five-minute period. The scans taken after meditation training showed that every participant`s pain ratings were reduced, with decreases ranging from 11 to 93 percent, Zeidan said. IANS
