Introduction[edit | edit source]
Evidence for the use of mindfulness has grown rapidly since its introduction to the Western world around 1979, with more than 2500 studies currently available on mindfulness (Figure 1).
Mindfulness-Based Interventions (MBI) are showing promising results in supporting mental health needs even in the absence of psychological disorders and have become a more popular, cost-effective method to provide the support. The benefits of MBI are well established and include:
- Decreased anxiety and depression
- Relieve of stress and psychological distress
- Increased coping abilities
- Alleviation of pain
- Decreased negative affect (decreased rumination)
- Enhanced cognitive control
- Emotion regulation
- Improved sleep
- Immune system support
Figure 2. Benefits of Mindfulness Practice
Cognitive Changes associated with Mindfulness[edit | edit source]
The greatest impact of mindfulness is its effect on the neural plasticity of the brain. Several changes in brain activation has been documented with the practice of mindfulness, allowing us to also “see” the benefits of MBI as is evident on functional Magnetic Resonance Imaging (fMRI). However, the study designs vary greatly with the use of different MBI and therefore the locations of the reported effects are diverse and spread over multiple regions of the brain. The brain regions most consistently altered with MBI are included in Table 1.
Table 1: Neural changes associated with mindfulness practice
|Region of the brain||Effect with MBI||Function of the region|
|Insula and sensory cortices||Increased activation||Body awareness (interoception)
|Anterior cingulate cortex (ACC)||Increased activation||Higher order cognitive processes
Attention and attention regulation
Self and emotional regulation
Cognitive distancing - associated with non-judgemental acceptance
|Prefrontal cortex||Increased activation||Higher order cognitive processes
Attention and attention regulation
Meta-awareness & reappraisal
Reasoning and decision making
Functional connectivity with the salience network
Downregulation of amygdala responses
Decrease in volume/size
Adds emotional value to sensory input - emotional processing
Greater stress is associated with greater amygdala activation. Down-regulation of the amygdala is what underscores the reduction in stress seen with Mindfulness-Based Stress Reduction (MBSR). Mindfulness is therefore not simply about paying attention. The way in which we use this focus of the mind ultimately changes the function and the structure of the brain. Just as we can train our muscles to grow, we can “train” our brains as is evident in the studies about mindfulness.
Mindfulness and Pain[edit | edit source]
Chronic pain poses a significant therapeutic challenge and has been declared a public health problem, placing burdens not only on those experiencing pain, but also society as a whole. Chronic pain is estimated to affect more than 100 million adults at any given time in the United States, with chronic back pain being the most commonly reported chronic pain complaint. Chronic pain is also one of the primary causes of disability and decreased quality of life, resulting in a cost of more than $600 billion dollars annually in the United States alone. Opioid medication is frequently prescribed in order to manage pain and its potential consequences, which contributed to many other problems including the “opioid epidemic” of opioid misuse, addiction and opioid-related deaths due to patients overdosing. Mindfulness, as a nonpharmacologic option, is receiving increased interest in the management of pain.
Chronic pain is complex in nature, involving many physical and psychological factors. It is associated with sleep disturbances, obesity and weight gain, chronic fatigue, limited physical functionality and decreased quality of life. Individuals suffering from a variety of chronically painful conditions are also at an increased risk for anxiety, depression and other affective disorders. The International Association for the Study of Pain (IASP) defines pain as “An unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage.” Treatment of pain should therefore also be multifaceted to address both the sensory component as well as the affective/emotional experience of pain. Treatments targeted at the negative affect associated with chronic pain are therefore hypothesised to not only positively influence the emotional distress but also influence the frequency and intensity of pain. Mindfulness as a multifaceted intervention is therefore ideally placed to have a positive effect on pain and pain affect without the negative effects associated with pharmacological interventions such as opioids.
MBSR is consistently showing positive improvements in pain management. Several studies have looked at the effect of MBI on various chronic conditions and various chronically painful conditions including chronic low back pain (LBP). Several of these studies can be found in Table 2.

MBIs are suggested to have greater effects on pain-related catastrophizing, especially in the presence of high levels of pain intensity, compared to traditional cognitive behavioural therapy (CBT) approaches. In general, participants practicing mindfulness (especially MBSR) for chronic pain, displayed significantly improved outcomes of pain measures as well as quality of life and mental health measures compared to matched control groups. Patients with chronic pain who engaged in mindfulness practice were generally found to be able to find new ways of living with and accepting pain, resulting in a less negative impact on their daily lives. The need for methodologically sound studies on MBI for patients with chronic pain is however reiterated in many studies.
Mechanism of Pain Reduction through Mindfulness Practice[edit | edit source]
Exploring the mechanisms by which mindfulness influences stress and pain, necessitate an explanation of the negative stress cycle that develops as a result of the long-term and unrelenting presence of stress and pain. The negative stress cycle is set off by the occurrence of a stressful event which is often not relenting. The patient enters into a cycle of automatic thoughts about this event (the stress/pain) which leads to negative moods and emotions, ultimately resulting in maladaptive behaviours which often end up sustaining this cycle by worsening their symptoms (Figure 3).
Figure 3. The Negative Stress Cycle
The practice of mindfulness is able to break this cycle by interrupting the “automatic thoughts” stage achieved through turning off the autopilot mode of living and guiding the awareness back to the present moment with an attitude of non-judgement and non-reactance. MBSR proposes that mindfulness practice “will allow for the “uncoupling” of the bottom-up, afferent, sensory-driven components of pain from the top-down, psychological, cortically-driven components of pain”. This suggests that awareness can result in a dissociation between the physical sensation of pain from the emotions and thoughts previously attached to pain. The goal of mindfulness, therefore, is not to eliminate the stress or pain, but to teach the patient self-awareness and alternate responses to stress and pain by embracing the pain, accepting the moment for what it is. By making peace with the pain, the patient is able to better manage the pain with fewer negative coping responses (including fear and anxiety).
Pain reduction through mindfulness meditation also utilises different neural mechanisms as compared to placebo analgesia. Besides its proposed influence on pain affect, mindfulness-based pain relief also engages brain mechanisms involved in mediating the cognitive modulation of pain, which include:
- decreased activity in neural regions associated with low-level nociceptive processing (eg thalamus)
- Increased activity in neural regions associated with interoceptive awareness (eg right anterior insula)
- Top-down executive control (eg ACC)
- Cognitive reappraisal of sensory information (eg orbitofrontal cortex)
The ultimate strength of mindfulness lies in the neural changes it causes. Keeping in mind that “nerves that fire together, wire together”, repetitive practice of mindfulness meditation leads to changes in neural pathways resulting in a more calm, accepting disposition towards life.
Several studies have found that long-term meditation practice can lead to increased pain threshold values and lower pain sensitivity even while the practitioners are not engaged in mindfulness practice. Grant et al studied Zen meditators using fMRI and found that long-term meditators had distinct neural pathways which predicted their low pain sensitivity. These neural pathways suggest a reduction in cognitive-emotional and evaluative processing during aversive stimulation which relates to reduced connectivity (greater “decoupling”) between the cognitive and evaluative areas of pain processing and the sensory component of pain processing. These Zen meditators still preserved the capacity to feel the pain on a sensory level, but displayed reduced affective appraisal, or less activation in the evaluative and emotional areas of the brain, related to the painful event. These pathways also correspond well to the psychological construct (present moment, non-judgemental awareness) of mindfulness which resulted in the meditators possessing quieter and less reactive brains.
