Reduce the Psychological and Physical Responses Before a Major Dental Procedure with Yogic Relaxation

Reduce the Psychological and Physical Responses Before a Major Dental Procedure with Yogic Relaxation

“Practicing yoga has been effectively proven to reduce stress levels and induce the sense of calmness in individuals, which could help in the management of several stress-induced oral conditions.” – Roquaiya Nishat

 

If you asked most people what’s one of the most common health problems that people have, probably the last thing that they would come up with is oral health. But more than 26% of adults in the United States have untreated tooth decay and 65% of adults had a dental visit every year. A common dental procedure is a root canal that is performed around 15 million times annually. But this procedure is accompanied by great anxiety and stress in the patients. This often results in patients avoiding or delaying needed procedures. There is considerable evidence that yoga practice reduces anxiety and stress. But it is not known if a brief yogic relaxation practice can reduce anxiety and stress prior to a dental root canal procedure.

 

In today’s Research News article “Effect of Pranayama Techniques with Marmanasthanam Kriya as Yogic Relaxation on Biopsychosocial Parameters Prior to Endodontic Therapy: A Cross Sectional Study Design.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8191219/ ) Thiruvalluvan and colleagues recruited adults between the ages of 25-50 years who were scheduled to undergo a dental root canal procedure and randomly assigned them to receive either guided Yogic relaxation for 15 minutes before the root canal treatment or to simply relax for 15 minutes. Yoga relaxation included breathing practices, mudras, and body scan exercises. The participants were measured before and after the intervention for anxiety, heart rate, and blood pressure.

 

They found that in comparison to baseline and the relaxation control group, the patients who practiced yogic relaxation had a significant decrease in anxiety, heart rate, and diastolic and systolic blood pressure. Hence, yogic relaxation prior to a dental root canal procedure reduced anxiety and physiological arousal in the patients. It is important to note that yogic relaxation produced superior results to simply asking the patient to relax. This suggests that yogic relaxation produces does more than simply relax the patients.

 

Yoga has been repeatedly shown to reduce anxiety, blood pressure, and heart rate in a variety of conditions. The present results demonstrate that a brief yogic relaxation can produce similar effects in patients before a major dental procedure. Anxiety and fear have been found to be major barriers to dental treatment. This leads to patients avoiding or delaying treatment allowing the damage to progress, So, a treatment that can reduce the anxiety before the treatment may be helpful in promoting dental health.

 

So, reduce the psychological and physical responses before a major dental procedure with yogic relaxation.

 

Yoga is versatile, enjoyable and highly beneficial and a great way for dentists and their patients to battle stress and anxiety. ‘– Saurabh Bhargava

Effect of Pranayama Techniques with Marmanasthanam Kriya as Yogic Relaxation on Biopsychosocial Parameters Prior to Endodontic Therapy: A Cross Sectional Study Design. International journal of yoga, 14(2), 146–151. https://doi.org/10.4103/ijoy.IJOY_133_20

 

Abstract

Background:

The root canal treatment is one of the common dental or endodontic therapies associated with high levels of patient anxiety. Yoga therapy (YT) is reported in medical literature as an effective modality in bringing down anxiety in clinical scenarios; however, the reports of the same for dental settings are fewer. The current study aimed to evaluate the effect of YT on biopsychosocial parameters in patients undergoing root canal therapy.

Materials and Methods:

A cross sectional study was conducted on 50 participants who underwent dental root canal therapy. The sample was divided into two groups: Yoga group (Group A; n = 25) who received YT and control group (Group B; n = 25) who were subjected to self-relaxation during dental procedure. The state of anxiety was measured by a 5-point single-item Likert scale and the cardiovascular (CV) parameters (systolic blood pressure [SBP], diastolic blood pressure [DBP], heart rate [HR]) and CV indices (pulse pressure [PP], mean arterial pressure [MAP], rate-pressure product [RPP], and double product [DoP]) were derived and compared between both the groups.

Results:

The intergroup comparison showed statistically significant differences in anxiety score (P < 0.001), SBP (P < 0.001), MAP (P < 0.001), RPP (P < 0.001), DoP (P < 0.001), HR (P < 0.029), DBP (P < 0.003), and PP (P < 0.116).

Conclusion:

A significant reduction was recorded in terms of anxiety and primary and derived CV parameters in the yoga group. The YT can be adopted as an interventional tool for anxiety management in patients indicated for dental root canal therapy.

Lower Cardiovascular Disease Risk by Improving Emotion Regulation with Mindfulness

Lower Cardiovascular Disease Risk by Improving Emotion Regulation with Mindfulness

 

By John M. de Castro, Ph.D.

 

“People who meditate regularly reported feeling more balanced and less stressed, and . . . improved the outcomes when they were added to cardiac rehabilitation programmes for patients with CHD.” – Heart Matters

 

Cardiovascular disease is the number one killer. A myriad of treatments has been developed including a variety of surgical procedures and medications. In addition, lifestyle changes have proved to be effective including quitting smoking, weight reduction, improved diet, physical activity, and reducing stresses. Unfortunately, for a variety of reasons, 60% of cardiovascular disease patients decline engaging in these lifestyle changes, making these patients at high risk for another attack.

 

Contemplative practices have been shown to be safe and effective alternative treatments for cardiovascular disease. Practices such as meditation, tai chi, and yoga, have been shown to be helpful for heart health and to reduce the physiological and psychological responses to stress. They have also been shown to be effective in maintaining cardiovascular health and the treatment of cardiovascular disease. The means by which mindfulness reduces cardiovascular disease risk have not been explored using the qualitative experiences of the patients.

 

In today’s Research News article “Mindfulness and cardiovascular health: Qualitative findings on mechanisms from the mindfulness-based blood pressure reduction (MB-BP) study.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7510988/ ) Nardi and colleagues recruited patients with hypertension who had participated in a study of the effectiveness of Mindfulness-Based Stress Reduction (MBSR) modified for hypertension, to reduce blood pressure. The participants participated in focus groups or were interviewed individually with semi-structured interviews. The groups and interviews focused on their experiences with the intervention and its effects. Transcripts of the responses were subjected to thematic analysis to identify common themes and ideas.

 

They found that the participants practiced breath awareness and body scans most in their everyday lives. Breath awareness allowed them to pause and relax to better address issues while the body scans made them more aware of their bodily states. These practices produced a greater awareness of the present moment and their responses to emotional situations allowing them to better regulate their emotions in these situations. They learned to apply self-kindness rather than self-criticism and to direct attention to mindfulness when stressful situations came up rather than worrying about them. All of this resulted in the improved ability to deal with their emotions. The participants indicated that they used the emotion regulation abilities to effectively deal with stress, learning to relax in the face of stress. This led to important changes in their health behaviors particularly diet.

 

These qualitative results suggest that the mindfulness program improved the patients’ cardiovascular health. It provided them with tools to employ when emotional situations arose to heighten their awareness of exactly what was transpiring and how they felt in the present moment. This resulted in better regulation of emotions which in turn led to better responses to stress and improved health behaviors.

 

These qualitative results correspond to the results of controlled empirical studies of the effects of mindfulness training on a wide variety of individuals and conditions. These studies found that mindfulness training produced improved emotion regulation, increased self-kindness, improved responses to stress, and improved cardiovascular health.  Hence, mindfulness training provides individuals with skills that improve their lives and well-beeing.

 

So, lower cardiovascular disease risk by improving emotion regulation with mindfulness.

Study Summary

 

Nardi, W. R., Harrison, A., Saadeh, F. B., Webb, J., Wentz, A. E., & Loucks, E. B. (2020). Mindfulness and cardiovascular health: Qualitative findings on mechanisms from the mindfulness-based blood pressure reduction (MB-BP) study. PloS one, 15(9), e0239533. https://doi.org/10.1371/journal.pone.0239533

 

Abstract

Background

Mindfulness-based programs hold promise for improving cardiovascular health (e.g. physical activity, diet, blood pressure). However, despite theoretical frameworks proposed, no studies have reported qualitative findings on how study participants themselves believe mindfulness-based programs improved their cardiovascular health. With an emphasis on in-depth, open-ended investigation, qualitative methods are well suited to explore the mechanisms underlying health outcomes. The objective of this qualitative study was to explore the mechanisms through which the mindfulness-based program, Mindfulness-Based Blood Pressure Reduction (MB-BP), may influence cardiovascular health.

Methods

This qualitative study was conducted as part of a Stage 1 single arm trial with one-year follow-up. The MB-BP curriculum was adapted from Mindfulness-Based Stress Reduction to direct participants’ mindfulness skills towards modifiable determinants of blood pressure. Four focus group discussions were conducted (N = 19 participants), and seven additional participants were selected for in-depth interviews. Data analysis was conducted using the standard approach of thematic analysis. Following double-coding of audio-recorded transcripts, four members of the study team engaged in an iterative process of data analysis and interpretation.

Results

Participants identified self-awareness, attention control, and emotion regulation as key mechanisms that led to improvements in cardiovascular health. Within these broader themes, many participants detailed a process beginning with increased self-awareness to sustain attention and regulate emotions. Many also explained that the specific relationship between self-awareness and emotion regulation enabled them to respond more skillfully to stressors. In a secondary sub-theme, participants suggested that higher self-awareness helped them engage in positive health behaviors (e.g. healthier dietary choices).

Conclusion

Qualitative analyses suggest that MB-BP mindfulness practices allowed participants to engage more effectively in self-regulation skills and behaviors lowering cardiovascular disease risk, which supports recent theory. Results are consistent with quantitative mechanistic findings showing emotion regulation, perceived stress, interoceptive awareness, and attention control are influenced by MB-BP.

Improve Post-Traumatic Stress Disorder (PTSD) Symptoms In Veterans With Body Scan or Breath Following Meditation.

Improve Post-Traumatic Stress Disorder (PTSD) Symptoms In Veterans With Body Scan or Breath Following Meditation.

 

By John M. de Castro, Ph.D.

 

“Practicing mindfulness can help you to be more focused and aware of the present moment while also being more willing to experience the difficult emotions that sometimes come up after trauma.” – National Center for PTSD

 

Experiencing trauma is quite common. It has been estimated that 60% of men and 50% of women will experience a significant traumatic event during their lifetime. But, only a fraction will develop Post-Traumatic Stress Disorder (PTSD). But this still results in a frightening number of people with 7%-8% of the population developing PTSD at some point in their life. For military personnel, it’s much more likely for PTSD to develop with about 11%-20% of those who have served in a war zone developing PTSD.

 

PTSD involves a number of troubling symptoms including reliving the event with the same fear and horror in nightmares or with a flashback. PTSD sufferers avoid situations that remind them of the event this may include crowds, driving, movies, etc. and may avoid seeking help because it keeps them from having to think or talk about the event. They often experience negative changes in beliefs and feelings including difficulty experiencing positive or loving feelings toward other people, avoiding relationships, memory difficulties, or see the world as dangerous and no one can be trusted. Sufferers may feel hyperarousal, feeling keyed up and jittery, or always alert and on the lookout for danger. They may experience sudden anger or irritability, may have a hard time sleeping or concentrating, may be startled by a loud noise or surprise.

 

Obviously, these are troubling symptoms that need to be addressed. There are a number of therapies that have been developed to treat PTSD. One of which, mindfulness training has been found to be particularly effective. The Mindfulness-based Stress reduction (MBSR) program has been found to improve the symptoms of PTSD. But MBSR training contains meditation, body scan, and yoga. It is not known which these components of mindfulness training are effective and which are not.

 

In today’s Research News article “The Body Scan and Mindful Breathing Among Veterans with PTSD: Type of Intervention Moderates the Relationship Between Changes in Mindfulness and Post-treatment Depression.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7451147/) Colgan and colleagues recruited military veterans who were diagnosed with Post-Traumatic Stress Disorder (PTSD). They were randomly assigned to one of 4 groups, body scan meditation, mindful breathing meditation, slow breathing and sitting quietly. Training was the same for all conditions with weekly 60-minute group meetings for 6 weeks along with home practice. Each condition was practiced for 20 minutes at a time. They were measured before and after training for mindfulness, including observing, describing, acting with awareness, nonjudgmental acceptance, and nonreactivity to inner experience facets, depression, and PTSD symptoms including re-experiencing, avoidance, and hyperarousal.

 

They found that the two mindfulness groups, body scan meditation and mindful breathing meditation produced significant increases in mindfulness and significant decreases in depression and PTSD symptoms while the non-mindfulness groups, slow breathing and sitting quietly, did not. Within the mindfulness groups the greater the levels of the mindfulness facet of acting with awareness the lower the depression scores. The greater the increases in nonreactivity the greater the decreases in depression for the body scan meditation group but not the mindful breathing meditation group. In contrast, the greater the increases in acting with awareness the greater the decreases in depression for the mindful breathing meditation group but not the body scan meditation group.

 

These are interesting results that replicate the prior findings that mindfulness training improves depression and Post-Traumatic Stress Disorder (PTSD) symptoms. The results further demonstrate the two different mindfulness trainings, body scan meditation, and mindful breathing meditation are effective in improving depression and PTSD symptoms. Mindfulness training programs also contain slowing of breathing and quiet sitting. These components do not involve training in mindfulness itself but rather are necessary for the mindfulness training. The present results demonstrate that these components are not effective, demonstrating that it’s only the active mindfulness training components that are effective.

 

The results also suggest that body scan meditation and mindful breathing meditation effect depression and PTSD symptoms in different ways. Body scan meditation appears to have its effects on depression through increasing nonreactivity to inner experience. This suggests that this training improves the ability recognize inner experience as simply experiences and thereby not reacting to them. On the other hand, mindful breathing meditation appears to work by increasing acting with awareness. This suggests that this training improves depression by making the individual more aware of their actions.

 

Having Post-Traumatic Stress Disorder (PTSD) is very difficult to deal with and can lead to very serious consequences such as suicide. It’s wonderful to have a safe and effective treatment, mindfulness, to lessen the torment of PTSD. The present study helps in further defining what components of mindfulness training work. This can lead to an even more effective treatment plan.

 

So, improve Post-Traumatic Stress Disorder (PTSD) symptoms in veterans with body scan or breath following meditation

Abstract

Mindfulness-based stress reduction (MBSR) is a promising intervention for veterans with post-traumatic stress disorder (PTSD) and depression; however, a more detailed examination of the different elements of MBSR and various facets of mindfulness to determine what works best for whom is warranted. One hundred and two veterans with PTSD were randomly assigned to one of four arms: (a) body scan (BS; n= 27), (b) mindful breathing (MB; n=25), (c) slow breathing (SB; n=25), or (d) sitting quietly (SQ; n=25). The purpose of this study was to (a) examine two separate components of MBSR (i.e., body scan and mindful breathing) among veterans with PTSD when compared to a nonmindfulness intervention (SB) and a control group (SQ), (b) assess if changes in specific mindfulness facets were predictive of post-treatment PTSD and depression for individuals who participated in a mindfulness intervention (BS vs. MB), and (c) investigate if type of mindfulness intervention received would moderate the relationship between pre- to post-treatment changes in mindfulness facets and post-treatment outcomes in PTSD and depression. Participants in the mindfulness groups experienced significant decreases in PTSD and depression symptom severity and increases in mindfulness, whereas the nonmindfulness groups did not. Among veterans who participated in a mindfulness group, change in the five facets of mindfulness accounted for 23 % of unique variance in the prediction of post-treatment depression scores. Simple slope analyses revealed that type of mindfulness intervention moderated the relationship among changes in facets of mindfulness and post-treatment depression.

Improve Physiological Symptoms Related to Anxiety in Remitted Depression with Mindfulness

Improve Physiological Symptoms Related to Anxiety in Remitted Depression with Mindfulness

 

By John M. de Castro, Ph.D.

 

Through mindfulness, individuals start to see their thoughts as less powerful. These distorted thoughts – such as “I always make mistakes” or “I’m a horrible person” – start to hold less weight. . . We ‘experience’ thoughts and other sensations, but we aren’t carried away by them. We just watch them come and go.” – Margarita Tartakovsky

 

Clinically diagnosed depression is the most common mental illness, affecting over 6% of the population. Major depression can be quite debilitating. Depression can be difficult to treat and is usually treated with anti-depressive medication. But, of patients treated initially with drugs only about a third attained remission of the depression. After repeated and varied treatments including drugs, therapy, exercise etc. only about two thirds of patients attained remission. But drugs often have troubling side effects and can lose effectiveness over time.

 

Many patients who achieve remission have relapses and recurrences of the depression. Even after remission some symptoms of depression including anxiety may still be present (residual symptoms). Obviously, there is a need for alternative treatments that can not only address depression but also the residual symptoms present during remission. Mindfulness training has been shown to be an effective treatment for depression and its recurrence and even in the cases where drugs fail. But there is a need to explore whether mindfulness training can also assist with the residual symptoms present during remission, including anxiety.

 

In today’s Research News article “Modulation of respiration pattern variability and its relation to anxiety symptoms in remitted recurrent depression.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7358718/) Zamoscik and colleagues recruited patients with at least 2 bouts of recurrent depression who were in remission for at least 2 months. They were randomly assigned to receive 4-week programs of either mindfulness training or progressive muscle relaxation training. Mindfulness training consisted of breath following and body scan meditations and breathing exercises. Before and after training they were measured for well-being and anxiety. They also had their brains scanned with functional Magnetic Resonance Imaging (fMRI) and respiration pattern variability was measured for 4.5 minutes during a sad mood induction by cuing memories of 3 negative life events.

 

They found that in comparison to the progressive muscle relaxation group, the group that received mindfulness training had significantly reduced variability of respiration. In addition, respiratory variability was associated with anxiety levels particularly in participants who were high in anxiety at baseline.

 

Anxiety often produces irregular breathing where relaxation produces regular breathing patterns. The variability of respiration then is a measure of anxiety levels. Hence, the results suggest that the mindfulness training reduced a physiological indicator of anxiety when a sad mood was invoked. An interpretive difficulty was produced by the fact that the training included both mindfulness exercises and also breathing exercises. Hence, it is unclear whether the effects were due to mindfulness training or breathing exercises or a combination of both.

 

Regardless, the results suggest that mindfulness may affect anxiety by affecting physiological processes that may underlie the feelings of anxiety. This occurred in patients who were in remission from recurrent depression. It has been well established that mindfulness training improves depression and reduces the likelihood of relapse. The finding suggest that mindfulness may reduce anxiety during remission which may in turn reduce the likelihood of the reoccurrence of depression.

 

So, improve physiological symptoms related to anxiety in remitted depression with mindfulness.

 

Mindfulness and other meditations, particularly combined with cognitive therapy, work just as well for anxiety or depression as the medications do, but they don’t have those side effects,”- Daniel  Goleman

Abstract

Background

Depression is related to default mode network (DMN) connectivity and higher respiration pattern variability (RPV). In addition, DMN connectivity and RPV are interrelated and predict a poorer clinical course of depression. The association of RPV and depression might further be boosted by anxiety levels. Aim of the present study was to investigate whether a mindfulness-based training in emotionally challenged remitted depressed participants (rMDD) leads to reduced DMN connectivity and lower RPV, and if RPV interacts with anxiety levels.

Methods

To challenge participants, sad mood was induced with keywords of personal negative life events in 49 rMDD during fMRI before and after a 4-week mindfulness-based attention training (MBAT) or progressive muscle relaxation. Respiration was measured by means of a built-in respiration belt.

Results

After both trainings, rMDD showed no significant changes in DMN connectivity. However, MBAT was effective in reducing the RPV which was related to lower anxiety levels especially in high anxious individuals.

Conclusions

RPV can be influenced by training which may hint to an underlying biological pathway of training effects. Importantly, these effects seem to be associated with anxiety levels. Therefore, respiration focused training might be an important tool assisting the treatment of depression and anxiety.

Brief Guided Meditations Improve Empathy

Brief Guided Meditations Improve Empathy

 

By John M. de Castro, Ph.D.

 

Empathy is the understanding and sharing of someone else’s feelings. It’s not to be confused with compassion, which is a feeling of concern for others that we feel we need to act on. Empathy goes that step further; by putting yourself in the place of someone else, you are appreciating how they feel, even if they’re experiencing something you’ve never encountered.” – Mindfulness Works

 

Humans are social animals. This is a great asset for the species as the effort of the individual is amplified by cooperation. In primitive times, this cooperation was essential for survival. But in modern times it is also essential, not for survival but rather for making a living and for the happiness of the individual. Mindfulness has been found to increase prosocial emotions such as compassion, and empathy and prosocial behaviors such as altruism.

 

It is not clear, however, exactly how meditation training improves empathy. Is it due to increased mindfulness or perhaps by the suggestion embedded in the measurements to be mindful of others. In today’s Research News article “How does brief guided mindfulness meditation enhance empathic concern in novice meditators?: A pilot test of the suggestion hypothesis vs. the mindfulness hypothesis.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7352088/) Miyahara and colleagues performed 2 studies of the effects of meditation on empathy.

 

In study 1 they recruited meditation naïve college students and randomly assigned them to listen to and practice brief (8 minute) recorded guided meditations of either breath following and body scan or compassion meditation. They were measured before and after the meditation for mindfulness, compassionate love, helping intention and empathy. They found that both meditations significantly increased all of the measures with no significant differences between meditation types. Study 2 was very similar to study 1 except there we no recorded guided meditations. They found that there were no significant changes in any of the measures from the first to the second measurement.

 

These results demonstrate that brief mindfulness meditations, regardless of whether they are breath and body meditations or compassion meditation produce increases in empathy and prosocial intentions in college students. The effects were not due to repeated measures. Hence, the suggestions for empathy and prosocial intentions embedded in the measurement instruments were not responsible for the changes, thus eliminating this alternative explanation for the effects. These results, then, suggest that it is improvements in mindfulness that result from brief meditation that are responsible for increased empathy.

 

So, brief guided meditations improve empathy.

Abstract

Despite the widespread popularity of mindfulness meditation for its various benefits, the mechanism underlying the meditation process has rarely been explored. Here, we present two preliminary studies designed to test alternative hypotheses: whether the effect of brief guided mindfulness meditation on empathic concern arises from verbal suggestion (suggestion hypothesis) or as a byproduct of an induced mindfulness state (mindfulness hypothesis). Study 1 was a pilot randomized control trial of sitting (breath-and-body) meditation vs. compassion meditation that provided preliminary support for the mindfulness hypothesis. Study 2 was set up to rule out the possibility that the meditation effects observed in Study 1 were the effects of repeated measures. An inactive control group of participants underwent the repeated measures of empathic concern with no meditation in between. The pre-post comparison demonstrated no significant changes in the measures. Thus, the results of two studies supported the mindfulness hypothesis. Limitations of the present study and future research directions are discussed.

People Select Mindfulness Training Techniques Based Upon Their Personal Characteristics

People Select Mindfulness Training Techniques Based Upon Their Personal Characteristics

 

By John M. de Castro, Ph.D.

 

Meditation is a simple strategy that can help obtain better health and a happier life. It takes time to master, as does any other skill. If a person sticks with it and is willing to experiment with the different methods, they are more likely to discover a meditation style that suits them.” – Medical News Today

 

Meditation training has been shown to improve health and well-being. It has also been found to be effective for a large array of medical and psychiatric conditions, either stand-alone or in combination with more traditional therapies. As a result, meditation training has been called the third wave of therapies. One problem with understanding meditation effects is that there are, a wide variety of meditation techniques and it is not known which work best for affecting different psychological areas.

 

Four types of meditation are the most commonly used practices for research purposes. In body scan meditation, the individual focuses on the feelings and sensations of specific parts of the body, systematically moving attention from one area to another. Loving kindness meditation is designed to develop kindness and compassion to oneself and others. The individual systematically pictures different individuals from self, to close friends, to enemies and wishes them happiness, well-being, safety, peace, and ease of well-being. In focused attention meditation, the individual practices paying attention to a single meditation object, learns to filter out distracting stimuli, including thoughts, and learns to stay focused on the present moment, filtering out thoughts centered around the past or future. On the other hand, in open monitoring meditation, the individual opens up awareness to everything that’s being experienced regardless of its origin. These include bodily sensations, external stimuli, and even thoughts. The meditator just observes these stimuli and lets them arise, and fall away without paying them any further attention.

 

There is little understanding as to why an individual chooses one meditation technique over another. In today’s Research News article “Predicting Individual Preferences in Mindfulness Techniques Using Personality Traits.” (See summary below or view the full text of the study at: https://www.frontiersin.org/articles/10.3389/fpsyg.2020.01163/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_1365539_69_Psycho_20200630_arts_A),  Tang and Braver examine the characteristics of individuals who choose either body scan meditationloving kindness meditationfocused attention meditation, or open monitoring meditation.

 

They recruited adults online who did not practice mindfulness or yoga and presented them with 5 daily recorded sessions. In the first 45-minute session the participants completed measures of mindfulness, big 5 personality traits, self-compassion, interpersonal reactivity, perceived stress, sensory processing sensitivity, and attentional control and absorption. They were also provided an introduction to meditation techniques with descriptions of all 4 techniques. On subsequent days they were directed by recorded instructions to practice for 15-20 minutes either body scan meditationloving kindness meditationfocused attention meditation, or open monitoring meditation. The order of the 4 practices was randomized for each participant. After each session they were asked questions regarding their content to ensure that they performed the practices. After completing all sessions, the participants were asked to rank them according to their preferences.

 

They found that all of the meditation techniques were about equally distributed in the preferences of the participants. There were no significant predictors of preferences for focused attention meditation or body scan meditation, but there were significant predictors of preferences for loving kindness meditation and open monitoring meditation. Female participants and participants who were high in empathy were significantly more likely to prefer loving kindness meditation. Participants who were high in the mindfulness facets of non-judging and non-reacting were significantly more likely to prefer open monitoring meditation.

 

These results make sense. Empathetic people, particularly women, are more sensitive to the feelings of others and so they would find meditating on those feelings, loving kindness meditation, more attractive. Open monitoring meditation. involves simply observing whatever is transpiring without judgement and reaction. So, it makes sense that people who were high in in the mindfulness facets of non-judging and non-reacting would find this form of meditation more attractive.

 

So, people select mindfulness training techniques based upon their personal characteristics.

Tang R and Braver TS (2020) Predicting Individual Preferences in Mindfulness Techniques Using Personality Traits. Front. Psychol. 11:1163. doi: 10.3389/fpsyg.2020.01163

 

The growing popularity of mindfulness-based interventions (MBIs) has prompted exciting scientific research investigating their beneficial effects on well-being and health. Most mindfulness programs are provided as multi-faceted packages encompassing a set of different mindfulness techniques, each with distinct focus and mechanisms. However, this approach overlooks potential individual differences, which may arise in response to practicing various mindfulness techniques. The present study investigated preferences for four prototypical mindfulness techniques [focused attention (FA), open monitoring (OM), loving-kindness (LK), and body scan (BS)] and identified factors that may contribute to individual differences in these preferences. Participants without prior mindfulness experiences were exposed to each technique through audio-guided instructions and were asked to rank their preferences at the end of all practices. Results indicated that preferences for loving-kindness were predicted by empathy, and that females tended to prefer loving-kindness more than males. Conversely, preferences for open monitoring were predicted by nonreactivity and nonjudgment of present moment experiences. Additionally, higher state mindfulness was detected for individuals’ preferred technique relative to other alternatives. These findings suggest that individuals tend to prefer techniques compatible with their personalities, as the predictor variables encompass trait capacities specifically relevant to practicing these techniques. Together, our results suggest the possibility that assessing individual difference and then tailoring MBIs to individual needs could be a useful way to improve intervention effectiveness and subsequent outcomes.

Different Meditation Types Produce Different Effects on Attention, Compassion, and Theory of Mind

Different Meditation Types Produce Different Effects on Attention, Compassion, and Theory of Mind

 

By John M. de Castro, Ph.D.

 

The mental procedures used by various traditions and schools of meditation are fairly dissimilar. And recent scientific research has verified that these different ways of meditating activate different areas in our brain.” – Trancendental Meditation

 

Meditation training has been shown to improve health and well-being. It has also been found to be effective for a large array of medical and psychiatric conditions, either stand-alone or in combination with more traditional therapies. As a result, meditation training has been called the third wave of therapies. One problem with understanding meditation effects is that there are, a wide variety of meditation techniques and it is not known which work best for affecting different psychological areas.

 

There are a number of different types of meditation. Classically they’ve been characterized on a continuum with the degree and type of attentional focus. In focused attention meditation, the individual practices paying attention to a single meditation object. In open monitoring meditation, the individual opens up awareness to everything that’s being experienced including thoughts regardless of its origin. In Loving Kindness Meditation the individual systematically pictures different individuals from self, to close friends, to enemies and wishes them happiness, well-being, safety, peace, and ease of well-being.

 

In today’s Research News article “Differential benefits of mental training types for attention, compassion, and theory of mind.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6891878/), Trautwein and colleagues recruited healthy adults and assigned them to one of three conditions; presence, affect, and perspective training. Each condition consisted of a 3-day retreat followed by once a week 2-hour training session for 13 weeks along with daily home practice. The presence training focused on attention to the present moment and contained focused breath meditation, walking meditation, and body scan practices. The affect training focused on developing an “accepting, kind, and compassionate stance towards oneself and others” and contained loving kindness meditation, forgiveness meditation, and affect dyad practices. The perspective training focused on the central role that thoughts play in our lives and contained meditation of observing thoughts coming and going and perspective dyads. They were measured before and after training with a cued flanker task measuring executive control and attentional reorienting and a Theory of Mind and Social Cognition task measuring social cognitive and affective functions including compassion. Theory of mind refers to the ability to observe self-awareness in self and others.

 

They found that in comparison to baseline and the other modules, the presence training significantly improved executive control and attentional reorienting. They also found that the affect and perspective training produced significant improvements in the socio-emotional dimension of compassion. Finally, they found that perspective training produced significantly higher scores on Theory of Mind (understanding beliefs, desires, and needs of others). Hence the three different forms of mindfulness training affected different abilities.

 

The findings suggest that training on present moment awareness affects attentional abilities but not socio-emotional and theory of mind abilities. On the other hand, affect training affects socio-emotional abilities including compassion but not attention or theory of mind abilities. Finally, the results suggest that perspective training affects socio-emotional and theory of mind abilities but not attentional abilities. These findings suggest that different mindfulness training programs should be employed to target specific problem areas for the participant. They also suggest that incorporating components from presence, affect, and perspective training may produce a training package that enhances abilities in all domains.

 

So, different meditation types produce different effects on attention, compassion, and theory of mind.

 

“Meditation is a simple strategy that can help obtain better health and a happier life. It takes time to master, as does any other skill. If a person sticks with it and is willing to experiment with the different methods, they are more likely to discover a meditation style that suits them.” – Zawn Villines

Study Summary

Abstract

Mindfulness- and, more generally, meditation-based interventions increasingly gain popularity, effectively promoting cognitive, affective, and social capacities. It is unclear, however, if different types of practice have the same or specific effects on mental functioning. Here we tested three consecutive three-month training modules aimed at cultivating either attention, socio-affective qualities (such as compassion), or socio-cognitive skills (such as theory of mind), in three training cohorts and a retest control cohort (N = 332). While attentional performance improved most consistently after attention training, compassion increased most after socio-affective training and theory of mind partially improved after socio-cognitive training. These results show that specific mental training practices are needed to induce plasticity in different domains of mental functioning, providing a foundation for evidence-based development of more targeted interventions adapted to the needs of different education, labor, and health settings.

Meditation Comes in Seven Different Varieties

Meditation Comes in Seven Different Varieties

 

By John M. de Castro, Ph.D.

 

Experienced meditators agree: a daily meditation practice can have significant benefits for mental and physical health. But one thing they probably won’t agree on? The most effective types of meditation. That’s simply because it’s different for everyone. After all, there are literally hundreds of meditation techniques encompassing practices from different traditions, cultures, spiritual disciplines, and religions.” Headspace

 

Meditation training has been shown to improve health and well-being. It has also been found to be effective for a large array of medical and psychiatric conditions, either stand-alone or in combination with more traditional therapies. As a result, meditation training has been called the third wave of therapies. One problem with understanding meditation effects is that there are, a wide variety of meditation techniques and it is not known which work best for improving different conditions.

 

There are a number of different types of meditation. Classically they’ve been characterized on a continuum with the degree and type of attentional focus. In focused attention meditation, the individual practices paying attention to a single meditation object. Transcendental meditation is a silent mantra-based focused meditation in which a word or phrase is repeated over and over again. In open monitoring meditation, the individual opens up awareness to everything that’s being experienced regardless of its origin. In Loving Kindness Meditation the individual systematically pictures different individuals from self, to close friends, to enemies and wishes them happiness, well-being, safety, peace, and ease of well-being.

 

But there are a number of techniques that do not fall into these categories and even within these categories there are a number of large variations. In today’s Research News article “What Is Meditation? Proposing an Empirically Derived Classification System.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6803504/), Matko and colleagues attempt to develop a more comprehensive system of classification. They found 309 different techniques but reduced them down to the 20 most popular ones. They recruited 100 meditators with at least 2 years of experience and asked them to rate how similar each technique was to every other technique.

 

They applied multidimensional scaling to the data which uncovered two dimensions that adequately described all of the 20 techniques. The analysis revealed a dimension of the amount of activation involved and a dimension of the amount of body orientation involved. All 20 techniques were classified within these two dimensions. Visual inspection of where the various techniques fell on the two dimensions produces 7 different clusters labelled as “(1) Body-centered meditation, (2) mindful observation, (3) contemplation, (4) mantra meditation, (5) visual concentration, (6) affect-centered meditation, and (7) meditation with movement.”

 

Within the high activation and low body orientation quadrant there was one cluster identified, labelled “Mantra Meditation” including singing sutras/mantras/invocations, repeating syllables and meditation with sounds. Within the low activation and low body orientation quadrant there were three clusters identified, labelled “affect-centered meditation” including cultivating compassion and opening up to blessings; “visual orientations” including visualizations and concentrating on an object; and “contemplation” including contemplating on a question and contradictions or paradoxes.

 

Within the high activation and high body orientation quadrant there was one cluster identified, labelled “meditation with movement” including “meditation with movement, manipulating the breath, and walking and observing senses. Within the low activation and high body orientation quadrant there was one cluster identified, labelled “mindful observation” including observing thoughts, lying meditation, and sitting in silence. Finally, they identified a cluster with high body but straddling the activation dimension, labelled “body centered meditation” including concentrating on a energy centers or channeling, body scan, abdominal breath, nostril breath, and observing the body.

 

This 7-category classification system is interesting and based upon the ratings of experienced meditators. So, there is reason to believe that there is a degree of validity. In addition, the system is able to encompass 20 different popular meditation techniques. It remains for future research to investigate whether this classification system is useful in better understanding the effects of meditation or the underlying brain systems.

 

Not all meditation styles are right for everyone. These practices require different skills and mindsets. How do you know which practice is right for you? “It’s what feels comfortable and what you feel encouraged to practice,” – Mira Dessy

Abstract

Meditation is an umbrella term, which subsumes a huge number of diverse practices. It is still unclear how these practices can be classified in a reasonable way. Earlier proposals have struggled to do justice to the diversity of meditation techniques. To help in solving this issue, we used a novel bottom-up procedure to develop a comprehensive classification system for meditation techniques. In previous studies, we reduced 309 initially identified techniques to the 20 most popular ones. In the present study, 100 experienced meditators were asked to rate the similarity of the selected 20 techniques. Using multidimensional scaling, we found two orthogonal dimensions along which meditation techniques could be classified: activation and amount of body orientation. These dimensions emphasize the role of embodied cognition in meditation. Within these two dimensions, seven main clusters emerged: mindful observation, body-centered meditation, visual concentration, contemplation, affect-centered meditation, mantra meditation, and meditation with movement. We conclude there is no “meditation” as such, but there are rather different groups of techniques that might exert diverse effects. These groups call into question the common division into “focused attention” and “open-monitoring” practices. We propose a new embodied classification system and encourage researchers to evaluate this classification system through comparative studies.

Reduce Muscular Spasticity After Stroke with Mindfulness

Reduce Muscular Spasticity After Stroke with Mindfulness

 

By John M. de Castro, Ph.D.

 

Mindfulness can have a profound effect on stroke rehabilitation by changing your brain and increasing motivation to recover.” – Flint Rehab

 

Every year, more than 795,000 people in the United States have a stroke and it is the third leading cause of death, killing around 140,000 Americans each year. A stroke results from an interruption of the blood supply to the brain, depriving it of needed oxygen and nutrients. This can result in the death of brain cells and depending on the extent of the damage produce profound loss of function. Even after recovery from stroke patients can experience residual symptoms. Problems with balance and falling are very common. About 30% of stroke survivors develop spasticity, where the muscles become stiff, tighten up, and resist stretching. Obviously, spasticity can interfere with regaining movement after stroke.

 

The ancient mindful movement technique Tai Chi and Qigong are very safe forms of gentle exercise that appears to be beneficial for stroke victims including improving balance. Tai Chi involves both gentle exercise and mindfulness practice. This raises the possibility that mindfulness practice by itself may be beneficial for stroke victims.

 

In today’s Research News article “Mindfulness Meditation Effects on Poststroke Spasticity: A Feasibility Study.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6585237/), Wathugala and colleagues recruited stroke patients with spasticity, aged 45 to 76 tears and provided them with a 14 day mindfulness training program with one guided session and 13 home practice sessions including body scan and sitting meditations. They were measured before and after training for spasticity, upper limb sensorimotor impairments, quality of life, anxiety, depression, and mindfulness.

 

They found that the mindfulness training resulted in a significant reduction in spasticity and improvements in the quality of life facets of energy, personality, and work productivity. In addition, the greater the self-reported quality of meditation the greater the reduction in spasticity. Written comments from the participants indicated that they enjoyed the meditations and believed that they were beneficial.

 

This was a small feasibility study without a control group. But it produced encouraging results that support conducting a large randomized controlled trial. The results suggest that a relatively brief, 2-week, mindfulness training may be beneficial for stroke patients with spasticity. It is not known how mindfulness training might reduce spasticity. But it can be speculated that the ability of mindfulness training to produce relaxation, reduce perceived stress, and to improve the regulation of emotions may be responsible.

 

So, reduce muscular spasticity after stroke with mindfulness.

 

“the combination of listening to music and practicing mindfulness can improve the lives of individuals recovering from stroke.” – Taylor Bennett

Wathugala, M., Saldana, D., Juliano, J. M., Chan, J., & Liew, S. L. (2019). Mindfulness Meditation Effects on Poststroke Spasticity: A Feasibility Study. Journal of evidence-based integrative medicine, 24, 2515690X19855941. doi:10.1177/2515690X19855941

 

Abstract

This study examined the feasibility of an adapted 2-week mindfulness meditation protocol for chronic stroke survivors. In addition, preliminary effects of this adapted intervention on spasticity and quality of life in individuals after stroke were explored. Ten chronic stroke survivors with spasticity listened to 2 weeks of short mindfulness meditation recordings, adapted from Jon Kabat-Zinn’s Mindfulness-Based Stress Reduction course, in a pre/post repeated measures design. Measures of spasticity, quality of life, mindfulness, and anxiety, along with qualitative data from participants’ daily journals, were assessed. On average, participants reported meditating 12.5 days of the full 15 days (mean 12.5 days, SD 0.94, range 8-15 days). Seven of the 10 participants wrote comments in their journals. In addition, there were no adverse effects due to the intervention. Exploratory preliminary analyses also showed statistically significant improvements in spasticity in both the elbow (P = .032) and wrist (P = .023) after 2 weeks of meditation, along with improvements in quality of life measures for Energy (P = .013), Personality (P = .026), and Work/Productivity (P = .032). This feasibility study suggests that individuals with spasticity following stroke are able to adhere to a 2-week home-based mindfulness meditation program. In addition, preliminary results also suggest that this adapted, short mindfulness meditation program might be a promising approach for individuals with spasticity following stroke. Future research should expand on these preliminary findings with a larger sample size and control group.

Meditation Alters the Perception of the Passage of Time

Meditation Alters the Perception of the Passage of Time

 

By John M. de Castro, Ph.D.

 

“Experienced meditators typically report that they experience time slowing down in meditation practice as well as in everyday life. Conceptually this phenomenon may be understood through functional states of mindfulness.” – Marc Wittmann

 

There are times in life when time just seems to wiz by and others when it seems to creep. There are also times when it seems like a minute passing feels like 5 minutes and others when it feels like only a few seconds. In other words, our sense of the speed of time passing and the amount of time that has passed varies from occasion to occasion. One factor that effects the perception of time is the content of the interval and the frequency of events occurring. If the interval is relatively packed with events and stimuli, then the time period is overestimated, suggesting that time seemed to pass more slowly. If, on the other hand, there are few things occurring in the interval, then time is underestimated, suggesting that time seemed to pass more quickly.

 

Meditation involves paying close attention to the contents of the present moment; calming the mind and reducing thinking and discursive thought. Focusing on the present moment would tend to fill awareness. This suggests that meditating would increase the apparent amount of things occurring and would thus predict that the interval would appear longer than otherwise.

 

In today’s Research News article “Mindfulness meditation, time judgment and time experience: Importance of the time scale considered (seconds or minutes).” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6799951/), Droit-Volet and colleagues recruited college students and randomly assigned them to receive either mindfulness meditation (body scan) or a control condition (listening to poems). In the first study, the mindfulness meditation participants listened to a guided body scan meditation while lying on their backs at home for 11 minutes daily for 7 days. The control condition was similar except they listened to recorded poems. They were then tested in the lab where they first meditated or listened to poems for 8 minutes and then were presented by tones separated either by short intervals (16-50 seconds) or long intervals (2-6 minutes) and were asked to estimated the duration of the intervals.

 

They found that the meditation group in comparison to the controls significantly underestimated the duration of the short intervals and significantly overestimated the duration of the longer intervals. During the session the meditation group but not the control group reported a significant reduction in anxiety and a significant increase in happiness and significantly faster passage of time.

 

In a second study a similar procedure was followed except that the same participants performed the meditation and also the control condition in counterbalanced order and only long intervals were used. In addition, they reported for each interval the passage of time, demands on their attention, task difficulty, present moment focus, and arousal levels.

 

Once again, they found that during the meditation session the participants overestimated the durations of the long intervals. They also indicated significantly longer passage of time, significantly greater demands on their attention, task difficulty, and present moment focus. They found that present moment awareness mediated the effect of meditation on duration estimates with the greater the focus on the present moment the greater the overestimation of the interval duration.

 

They suggest that the underestimation of the short intervals by the meditation group was due to the effects of attentional focus on the apparent passage of time with high degrees of attentional focus occupying the mind such that there is little resource left for assessing the passage of time. The results also suggest that the overestimation of long intervals was due to attention on the present moment. By focusing on the contents of awareness in the present moment there is a greater amount of stimuli in awareness, filling awareness. More happening signals a greater amount of time passing. Regardless of the explanation, the study demonstrates that meditation alters the estimation of time passage.

 

So, meditation alters the perception of the passage of time.

Abstract

This manuscript presents two studies on the effect of mindfulness meditation on duration judgment and its relationship to the subjective experience of time when the interval durations are on the second or the minute time scale. After the first 15 minutes of a 30-min meditation or control exercise, meditation-trained participants judged interval durations of 15 to 50 s or 2 to 6 min, during which they performed either a mindfulness meditation exercise or a control exercise. The participants’ scores on the self-reported scales indicated the effectiveness of the meditation exercise, as it increased the level of present-moment awareness and happiness and decreased that of anxiety. The results showed an underestimation of time for the short interval durations and an overestimation of time for the long intervals, although the participants always reported that time passed faster with meditation than with the control exercise. Further statistical analyses revealed that the focus on the present-moment significantly mediated the exercise effect on the time estimates for long durations. The inversion in time estimates between the two time scales is explained in terms of the different mechanisms underlying the judgment of short and long durations, i.e., the cognitive mechanisms of attention and memory, respectively.
