People who meditate regularly find pain less unpleasant because their brains anticipate the pain less, a new study has found.

The type of meditation practised also varied across individuals, but all included 'mindfulness meditation' practices, such as those that form the basis of Mindfulness-Based Cognitive Therapy (MBCT), recommended for recurrent depression by the National Institute for Health and Clinical Excellence (NICE) in 2004.
"Meditation is becoming increasingly popular as a way to treat chronic illness such as the pain caused by arthritis," said Dr Christopher Brown, who conducted the research. "Recently, a mental health charity called for meditation to be routinely available on the NHS to treat depression, which occurs in up to 50% of people with chronic pain. However, scientists have only just started to look into how meditation might reduce the emotional impact of pain."
The study, to be published in the journal Pain, found that particular areas of the brain were less active as meditators anticipated pain, as induced by a laser device. Those with longer meditation experience (up to 35 years) showed the least anticipation of the laser pain.
Dr Brown, who is based in Manchester's School of Translational Medicine, found that people who meditate also showed unusual activity during anticipation of pain in part of the prefrontal cortex, a brain region known to be involved in controlling attention and thought processes when potential threats are perceived.
He said: "The results of the study confirm how we suspected meditation might affect the brain. Meditation trains the brain to be more present-focused and therefore to spend less time anticipating future negative events. This may be why meditation is effective at reducing the recurrence of depression, which makes chronic pain considerably worse."

"However, the importance of developing new treatments for chronic pain is clear: 40% of people who suffer from chronic pain report inadequate management of their pain problem."

Study co-author Professor Anthony Jones said: "One might argue that if a therapy works, then why should we care how it works? But it may be surprising to learn that the mechanisms of action of many current therapies are largely unknown, a fact that hinders the development of new treatments. Understanding how meditation works would help improve this method of treatment and help in the development of new therapies.
"There may also be some types of patient with chronic pain who benefit more from meditation-based therapies than others. If we can find out the mechanism of action of meditation for reducing pain, we may be able to screen patients in the future for deficiencies in that mechanism, allowing us to target the treatment to those people."
