Recent findings have demonstrated that mindfulness meditation significantly reduces pain. Given that the "gold standard" for evaluating the efficacy of behavioral interventions is based on appropriate placebo comparisons, it is imperative that we establish whether there is an effect supporting meditation-related pain relief above and beyond the effects of placebo. Here, we provide novel evidence demonstrating that mindfulness meditation produces greater pain relief and employs distinct neural mechanisms than placebo cream and sham mindfulness meditation. Specifically, mindfulness meditation-induced pain relief activated higher-order brain regions, including the orbitofrontal and cingulate cortices. In contrast, placebo analgesia was associated with decreased pain-related brain activation. These findings demonstrate that mindfulness meditation reduces pain through unique mechanisms and may foster greater acceptance of meditation as an adjunct pain therapy. MORE.

The effectiveness of meditation in treating an array of illnesses has led to studies of how meditation can change the brainmeditation class. Since Herbert Benson, the cardiologist and author of the ground-breaking 1975 book “The Relaxation Response,” first began pioneering mind-body research 40 years ago, numerous scientific studies have have reported positive results from meditation in a wide range of ailments, including high blood pressure, stroke risk, heart disease, weight management, chronic pain, and mental health.

This is yet another outstanding research result from the Benson-Henry Institute and Harvard Medical School. Both short-term and long-term practitioners evoked significant temporal gene expression changes with greater significance in the latter as compared to novices. Relaxation response practice enhanced expression of RNA associated with energy metabolism, mitochondrial function, insulin secretion and telomere maintenance, and reduced expression of RNA linked to inflammatory response and stress-related pathways. This research proves some of the most significant benefits of Qigong practice. Also see Meditation Produces Opposite Effect of ‘Fight or Flight’.

The authors suggest that reversing homeostatic alterations with meditation and breathing techniques rather than targeting neurotransmitters with medication may be a superior method to address the whole body changes that occur in stress, anxiety, and depression. Detrimental effects of stress, negative emotions, and sympathetic dominance of the autonomic nervous system have been shown to be counteracted by different forms of meditation, relaxation, and breathing techniques. These breathing techniques could be used as first-line and supplemental treatments for stress, anxiety, depression, and some emotional disorders.

Harvard Scientists Have Good News for People Who Meditate. The news: It turns out meditating is good for more than just quiet time: It can actually help us fight the cripplingly high stress levels we experience during our busy lives, in the office or elsewhere. Scientists from Harvard University and the University of Sienna recently found that meditation is so powerful it can change the physiology of a person's brain, resulting in positive changes like a decrease in anxiety and depression.

Mindfulness relieves anxiety. Brain regions associated with meditation-related anxiety relief were found to be remarkably consistent with the principles of being mindful. Arterial spin labeling (ASL) magnetic resonance imaging was used to identify brain regions activated during meditation. Arterial spin labeling allows the weighting of the fMRI signal by the actual cerebral blood flow.

Demystifying Meditation: Brain Imaging Illustrates How Meditation Reduces Pain. Meditation produces powerful pain-relieving effects in the brain. Both before and after meditation training, study participants' brain activity was examined using a special type of imaging -- arterial spin labeling magnetic resonance imaging (ASL MRI) -- that captures longer duration brain processes, such as meditation, better than a standard MRI scan of brain function.

Meditation Reduces the Emotional Impact of Pain. People who meditate regularly find pain less unpleasant because their brains anticipate the pain less.

Brief Training In Meditation May Help Manage Pain. Living with pain is stressful, but a surprisingly short investment of time in mental training can help you cope. A single hour of meditation over a three day period can have the same effect as extensive meditation training.

Meditation can ease pain from stress-related conditions like IBS and arthritis. People who suffer from painful conditions such as rheumatoid arthritis could ease their symptoms using a form of meditation, say researchers.They added that the treatment, known as mindfulness, could prove a cheaper alternative to prescription medicines. Mindfulness meditation involves 'being present' by focusing on breathing patterns and bodily sensations. This reduces worrying about the past and future and has been shown to be effective at alleviating depression. University of Wisconsin-Madison Press Release: Mindfulness meditation may relieve chronic inflammation. People suffering from chronic inflammatory conditions, such as rheumatoid arthritis, inflammatory bowel disease and asthma — in which psychological stress plays a major role — may benefit from mindfulness meditation techniques, according to a study by University of Wisconsin-Madison neuroscientists with the Center for Investigating Healthy Minds at the Waisman Center. Mindfulness-based stress reduction, originally designed for patients with chronic pain, consists of continuously focusing attention on the breath, bodily sensations and mental content while seated, walking or practicing yoga.

Psychological Health

Meditation reduced psychosocial stress and depression in patients with various conditions such as type-2 diabetes, type-D distressed personality traits, social stress and social anxiety disorder [Hartmann] [Nyklicek] [Britton] [van Son ] [Jazaieri] [Chen]; it improved the quality of life of people living with HIV [Gayner] and improves sleep [Brand]. A systematic literature review showed a moderate to large positive effect on the mental health of breast cancer patients [Zainal]. A University of Western Sydney study found that just fifteen minutes of meditation significantly reduced perceived stress [Melville]. A Stanford University study using fMRI found meditation more effective than an aerobic exercise stress reduction program in reducing negative emotions and social anxiety through increasing attention regulation[Goldin]. A randomized controlled trial showed that mindfulness based stress reduction helps in two measures (quality of life and stress) in patients with asthma, but it did not help lung function [Pbert]. This suggests that Qigong is more clinically effective than meditation alone because Qigong includes respiratory exercise in addition to meditation.

Meditation Programs for Psychological Stress and Well-being A Systematic Review and Meta-analysis. Clinicians should be aware that meditation programs can result in small to moderate reductions of multiple negative dimensions of psychological stress. Thus, clinicians should be prepared to talk with their patients about the role that a meditation program could have in addressing psychological stress. Stronger study designs are needed to determine the effects of meditation programs in improving the positive dimensions of mental health and stress-related behavior. JAMA Internal Medicine.

Study Reveals Gene Expression Changes with Meditation. The study investigated the effects of a day of intensive mindfulness practice in a group of experienced meditators, compared to a group of untrained control subjects who engaged in quiet non-meditative activities. After eight hours of mindfulness practice, the meditators showed a range of genetic and molecular differences, including altered levels of gene-regulating machinery and reduced levels of pro-inflammatory genes, which in turn correlated with faster physical recovery from a stressful situation.

Meditation linked to better well-being and health. A University of Sydney study found the health and well-being profile of people who had meditated for at least two years was significantly higher in the majority of health and wellbeing categories when compared to the Australian population.

Positive psychological changes from meditation training linked to cellular health and anti-aging. Positive psychological changes that occur during meditation training are associated with greater telomerase activity, according to researchers at the University of California, Davis, and the University of California, San Francisco. The study is the first to link positive well-being to higher telomerase, an enzyme important for the long-term health of cells in the body. The effect appears to be attributable to psychological changes that increase a person's ability to cope with stress and maintain feelings of well-being.
