Improve Decision Making with a Brief Mindfulness Training

 

By John M. de Castro, Ph.D.

 

“With mindfulness, the decision-making process becomes a thoughtful, cognitive exercise, rather than an impulsive reaction to immediate needs.” – Insead

 

We are confronted daily with a myriad of decisions, many small of little importance; chocolate or strawberry, pass or follow, do the dishes or empty the trash, watch a movie or sports, etc. But some have a major impact on ourselves and others; take a new job, get married, buy a home, retire or stay working, exercise or not, etc. The problem is that humans are not always good decision makers.

 

We often make decisions for emotional reasons; buying a new car, not because we need one but because it makes us feel like a race car driver, selling a stock out of fear of losses, marrying someone out of fear of being alone, etc. We also have a tendency to make decisions based upon how we’ve made them in the past regardless of whether that strategy is still appropriate. Having decided to finish high school, get a college degree, and going back to school to get an MBA may have helped our careers, but then going back to school again may not.

 

So, decisions are not always logical or optimal. Mindfulness has been shown to help with decision making. One problem, though, with mindfulness training is that it can take a great deal of time. This is not always possible when decisions must be made quickly. It is unclear if a very brief instruction in mindfulness may help individuals in making better decisions.

 

In today’s Research News article “The Effect of a 3-Minute Mindfulness Intervention, and the Mediating Role of Maximization, on Critical Incident Decision-Making.” (See summary below or view the full text of the study at: https://www.frontiersin.org/articles/10.3389/fpsyg.2021.674694/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_1651992_69_Psycho_20210603_arts_A )  Shortland and colleagues recruited adult participants online and randomly assigned them to a 3 minute meditation or story listening. The participants completed a measure of maximization of decision making. They them completed their 3-minute meditation or listening followed by a decision-making task with presented audio scenarios that had approach or avoidance solutions. They then measured situational awareness time, choice time, decision time, commitment time, decision difficulty, and approach/avoidance decision.

 

They found that the meditation group had significantly faster reaction times on all measures and higher decision difficulty. In addition, the mindfulness group were significantly more approach oriented rather than avoidance oriented in their decisions. But decisions became more avoidant after mindfulness training in participants who scored high in maximization of decision making. So, mindfulness training improved decision making by individuals who tend to find optimal solutions rather than acceptable solutions and find decisions less difficult to make.

 

The results are interesting and demonstrate that even a very brief exposure to mindfulness has positive effects on decision making. This suggests that prior to making complex difficult decision a brief period of meditation might be helpful, but particularly in individuals who look for optimal solutions.

 

So, improve decision making with a brief mindfulness training.

Study Summary

 

Shortland ND, McGarry P, Thompson L, Stevens C and Alison LJ (2021) The Effect of a 3-Minute Mindfulness Intervention, and the Mediating Role of Maximization, on Critical Incident Decision-Making. Front. Psychol. 12:674694. doi: 10.3389/fpsyg.2021.674694

 

Objective: In this study, we extend the impact of mindfulness to the concept of least-worst decision-making. Least-worst decisions involve high-uncertainty and require the individual to choose between a number of potentially negative courses of action. Research is increasingly exploring least-worst decisions, and real-world events (such as the COVID-19 pandemic) show the need for individuals to overcome uncertainty and commit to a least-worst course of action. From sports to business, researchers are increasingly showing that “being mindful” has a range of positive performance-related benefits. We hypothesized that mindfulness would improve least-worst decision-making because it would increase self-reflection and value identification. However, we also hypothesized that trait maximization (the tendency to attempt to choose the “best” course of action) would negatively interact with mindfulness.

Methods: Three hundred and ninety-eight participants were recruited using Amazon MTurk and exposed to a brief mindfulness intervention or a control intervention (listening to an audiobook). After this intervention, participants completed the Least-Worst Uncertain Choice Inventory for Emergency Responders (LUCIFER).

Results: As hypothesized, mindfulness increased decision-making speed and approach-tendencies. Conversely, for high-maximizers, increased mindfulness caused a slowing of the decision-making process and led to more avoidant choices.

Conclusions: This study shows the potential positive and negative consequences of mindfulness for least-worst decision-making, emphasizing the critical importance of individual differences when considering both the effect of mindfulness and interventions aimed at improving decision-making.

“In the NBA, mindfulness is important because the game is chaotically fast and the pressures on players are extreme. In real life, it’s important because the practice can help us get a handle on ourselves and stop going into a tailspin or endless series of tangents.”

Improve Physical and Mental Health with an Isha Yoga Retreat

 

By John M. de Castro, Ph.D.

 

“As we have physical science to create external wellbeing there is a whole inner dimension of science to create inner wellbeing. I call it Inner Engineering.” – Sadhguru

 

Retreat can be a powerful experience. But it can be quite difficult and challenging. It can be very tiring and physically challenging as engaging in sitting meditation repeatedly over the day is guaranteed to produce many aches and pains in the legs, back, and neck. But the real challenges are psychological, emotional, and spiritual. Retreat can be a real test. The darkness can descend. Deep emotional issues can emerge and may even overwhelm the individual. With all these difficulties, why would anyone want to put themselves through such an ordeal and go on a meditation retreat? People go because they find that retreat produces many profound and sometimes life altering benefits.

 

In today’s Research News article “Isha Yoga Practices and Participation in Samyama Program are Associated with Reduced HbA1C and Systemic Inflammation, Improved Lipid Profile, and Short-Term and Sustained Improvement in Mental Health: A Prospective Observational Study of Meditators.” (See summary below or view the full text of the study at: https://www.frontiersin.org/articles/10.3389/fpsyg.2021.659667/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_1645362_69_Psycho_20210525_arts_A )   Sadhasivam and colleagues recruited adult participants in a scheduled 8-day Isha yoga retreat and their spouses as controls. Retreat participants had to engage in 2 months of preparatory practices including a vegan diet daily practice of hata yoga, kriya yoga, and Shoonya meditation. In the retreat there was intensive practice. They were measured before, after, and 3-4 months later for depression, anxiety, mindfulness, joy, vitality, and resilience, diet, yoga practice, dietary restrictions, and overall health/well-being. They also had blood drawn and assayed for hemoglobin A1c (HbA1c), hemoglobin (Hb), lipid profile [cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), and triglycerides (TG)], and C-reactive protein (CRP).

 

They found that after the retreat and sustained 3-4 months later were significant decreased in anxiety and depression and significant increases in mindfulness, joy, vitality, resilience, blood triglycerides, and body weight. These changes did not occur in the control group. Previous research has similarly demonstrated that yoga and meditation decreases anxiety, depression, blood triglycerides and increases joy, vitality, resilience, and body weight.

 

The study did not have a comparable control group and as a result there are a number of possible alternative explanations for the results including participant expectancy effects. To sign up for and engage in an intensive retreat, there was likely a strong belief that the retreat would be beneficial producing a strong expectancy (placebo) effect. Future research should include a comparison to a different kind of retreat or, as has been used in other studies, a comparison to the effects of a comparable duration vacation.

 

The results are interesting in that the participants had considerable practice during the 2-month preparatory phase. So, the effects of the practices would be expected to be present before the retreat began. So, the improvements observed were due to participation in a 4-day intensive retreat rather than the practices themselves. The retreat involves residential living in a group and withdrawal from daily life. This has social effects and vacation-like effects of removal of life stressors. These could be responsible for the observed benefits. This supports the need for future better controlled research.

 

So, improve physical and mental health with an Isha yoga retreat.

Study Summary

 

Sadhasivam S, Alankar S, Maturi R, Williams A, Vishnubhotla RV, Hariri S, Mudigonda M, Pawale D, Dubbireddi S, Packiasabapathy S, Castelluccio P, Ram C, Renschler J, Chang T and Subramaniam B (2021) Isha Yoga Practices and Participation in Samyama Program are Associated with Reduced HbA1C and Systemic Inflammation, Improved Lipid Profile, and Short-Term and Sustained Improvement in Mental Health: A Prospective Observational Study of Meditators. Front. Psychol. 12:659667. doi: 10.3389/fpsyg.2021.659667

 

Background: Meditation is gaining recognition as a tool to impact health and well-being. Samyama is an 8-day intensive residential meditation experience conducted by Isha Foundation requiring several months of extensive preparation and vegan diet. The health effects of Samyama have not been previously studied. The objective was to assess physical and emotional well-being before and after Samyama participation by evaluating psychological surveys and objective health biomarkers.

Methods: This was an observational study of 632 adults before and after the Isha Samyama retreat. All participants were invited to complete surveys. Controls included household significant others. Surveys were completed at baseline (T1), just before Samyama (T2), immediately after Samyama (T3), and 3 months later (T4) to assess anxiety, depression, mindfulness, joy, vitality, and resilience through validated psychometric scales. Voluntary blood sampling for biomarker analysis was done to assess hemoglobin (Hb), HbA1c, lipid profile, and C-reactive protein (CRP). Primary outcomes were changes in psychometric scores, body weight, and blood biomarkers.

Results: Depression and anxiety scores decreased from T1 to T3, with the effect most pronounced in participants with baseline depression or anxiety. Scores at T4 remained below baseline for those with pre-existing depression or anxiety. Vitality, resilience, joy, and mindfulness increased from T1 to T3 (sustained at T4). Body weight decreased by 3% from T1 to T3. Triglycerides (TG) were lower from T2 to T3. Participants had lower HbA1c and HDL at T2, and lower CRP at all timepoints compared with controls.

Conclusions: Participation in the Isha Samyama program led to multiple benefits. The 2-month preparation reduced anxiety, and participants maintained lower anxiety levels at 3 months post-retreat. Physical health improved over the course of the program as evidenced by weight loss and improved HbA1C and lipid profile. Practices associated with the Samyama preparation phase and the retreat may serve as an effective way to improve physical and mental health. Future studies may examine their use as an alternative therapy in patients with depression and/or anxiety.

Meditation Reduces the Complexity of Brain Activity

Meditation Reduces the Complexity of Brain Activity

 

By John M. de Castro, Ph.D.

 

“What happens in your brain when you meditate. . . The overall difference is that our brains stop processing information as actively as they normally would.” – Belle Beth Cooper

 

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. There are a number of ways that meditation practices produce these benefits, including changes to the brain and physiology. One way to observe the effects of meditation on neural activity is to measure changes in the electroencephalogram (EEG), the rhythmic electrical activity that can be recorded from the scalp.

 

In today’s Research News article “Contrasting Electroencephalography-Derived Entropy and Neural Oscillations With Highly Skilled Meditators.” (See summary below or view the full text of the study at:  https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8119624/ ) Young and colleagues recruited experienced meditators who engaged in six different meditation styles (shamatha, vipassana, zazen, dzogchen, tonglen, and visualization). They had on average 21,935 hours of meditation experience. The researchers then recorded the Electroencephalogram (EEG) while the meditators were thinking about their day and also during meditation practice. The EEG recordings were analyzed for entropy and their power spectra.

 

They found that tonglen and zazen meditators had the highest alpha rhythm power during meditation compared to other styles of meditation. But different styles had markedly different patterns. On the other hand, overall, with all meditation types there was a significant reduction in entropy of the brain activity during meditation.

 

The differences in the power spectrum observed with different meditation types probably reflects the different mental activity encouraged by the individual practices, On the other hand there were consistent findings with the entropy measures suggesting a common element of neural activity occurring with meditation regardless of its form.

 

Entropy of the pattern of Electroencephalogram (EEG) activity is a measure of the complexity of the activity. The reduction in entropy observed during meditation suggests that meditation is associated with a simplification of brain activity. This makes sense as during meditation attention is focused, reducing the variety of mental activity. Hence, the simplified mental experiences during meditation are reflected in a simplified neural activity.

 

So, meditation reduces the complexity of brain activity.

 

“It seems the longer you do meditation, the better your brain will be at self-regulation. You don’t have to consume as much energy at rest and you can more easily get yourself into a more relaxed state.” – Bin He

Abstract

Meditation is an umbrella term for a number of mental training practices designed to improve the monitoring and regulation of attention and emotion. Some forms of meditation are now being used for clinical intervention. To accompany the increased clinical interest in meditation, research investigating the neural basis of these practices is needed. A central hypothesis of contemplative neuroscience is that meditative states, which are unique on a phenomenological level, differ on a neurophysiological level. To identify the electrophysiological correlates of meditation practice, the electrical brain activity of highly skilled meditators engaging in one of six meditation styles (shamatha, vipassana, zazen, dzogchen, tonglen, and visualization) was recorded. A mind-wandering task served as a control. Lempel–Ziv complexity showed differences in nonlinear brain dynamics (entropy) during meditation compared with mind wandering, suggesting that meditation, regardless of practice, affects neural complexity. In contrast, there were no differences in power spectra at six different frequency bands, likely due to the fact that participants engaged in different meditation practices. Finally, exploratory analyses suggest neurological differences among meditation practices. These findings highlight the importance of studying the electroencephalography (EEG) correlates of different meditative practices.

Improve Attention, Memory, and Emotions with Meditation

Improve Attention, Memory, and Emotions with Meditation

 

By John M. de Castro, Ph.D.

 

“meditating can change the structure and function of the brain through relaxation, which can: Reduce stress, anxiety, and depression, Increase focus and learning concentration, Improve memory and attention span, Build stronger immune system and greater physical/psychological resilience, Allow better sleep” – Columbia University

 

Mindfulness training has been shown to be effective in improving physical and psychological health and particularly with the physical and psychological reactions to stress. Mindfulness also decreases the individual’s tendency to use tried and true solutions to problems and thereby improves cognitive flexibility. Mindfulness has also been shown to improve attention, memory, and emotions. This has led to an increasing adoption of these mindfulness techniques for the health and well-being of both healthy and ill individuals.There are, however, a large variety of meditation techniques and it is not known which types are best for which benefit.

 

In today’s Research News article “Effects of Combining Meditation Techniques on Short-Term Memory, Attention, and Affect in Healthy College Students.” (See summary below or view the full text of the study at: https://www.frontiersin.org/articles/10.3389/fpsyg.2021.607573/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_1616048_69_Psycho_20210504_arts_A )  Pragya and colleagues recruited college students and randomly assigned them to one of three meditation groups or to a no-treatment control group. Meditation occurred in 3 25-minute sessions per week for 8 weeks and was either a sound meditation (Bee sound), color imagery (green) or the combination of the two. They were measured before and after training for short-term memory and positive and negative emotions. They also completed a continuous performance test to measure selective attention, sustained attention, and impulsivity.

 

They found that in comparison to baseline and the control group the combined meditation groups had significantly greater short-term memory and positive emotions and significantly lower negative emotions, inattention, and impulsivity. The two types of meditation techniques and their combination had somewhat different magnitudes of effects. Sound meditation had greater improvements of attention and reductions in negative emotions, while the color focused meditation group had greater attentiveness and short-term memory. The combined color and sound meditation group had the greatest improvements.

 

These results demonstrate as has been previously reported that mindfulness practices produce greater short-term memory and positive emotions and significantly lower negative emotions, inattention, and impulsivity. The contribution of the present study is to demonstrate that different meditation techniques produce similar effects but differ in the magnitudes of those effects. This could help to determine which techniques work best for people with different weaknesses. Regardless, meditation appear to improve cognitive and emotional well-being.

 

So, improve attention, memory, and emotions with meditation.

 

“A critical part of attention (and working memory capacity) is being able to ignore distraction. There has been growing evidence that meditation training (in particular mindfulness meditation) helps develop attentional control, and that this can start to happen very quickly.” – About memory

Psychol. 12:607573. doi: 10.3389/fpsyg.2021.607573

 

Meditation refers to a family of self-regulation practices that focuses on training attention and awareness to foster psycho-emotional well-being and to develop specific capacities such as calmness, clarity, and concentration. We report a prospective convenience-controlled study in which we analyzed the effect of two components of Preksha Dhyāna – buzzing bee sound meditation (Mahapran dhvani) and color meditation (leśyā dhyāna) on healthy college students. Mahapran and leśya dhyāna are two Preksha Dhyāna practices that are based on sound and green color, respectively. The study population represents a suitable target as college students experience different stress factors during the school year. This study measures the individual and combined effects of two techniques (one focusing on sound and one focusing on color), on short-term memory, attention, and affect, in novice meditators. We used a battery of cognitive, performance, and compared results with baseline and control values. We found improved cognition, especially attention, short-term memory, and affect in terms of positivity and reduced negativity. Overall, the two techniques produced variable benefits and subjects showed improved scores over baseline for short-term memory, cognitive function, and overall wellbeing. Further studies are required to understand underlying mechanisms for the observed differences between the two techniques and to elucidate mechanisms underlying the more pronounced and global benefits observed with the combined techniques. These results underscore a need to examine individual components of meditation practices in order to individualize treatment approaches for attention disorders in young adults.

Mindfulness Training Increases the Use of Yoga and Meditation to Cope with the Covid-19 Lockdown

Mindfulness Training Increases the Use of Yoga and Meditation to Cope with the Covid-19 Lockdown

 

By John M. de Castro, Ph.D.

 

“mindfulness is one tool that can help promote mental wellness throughout the COVID-19 pandemic and beyond.” – Julie Dunne

 

Mindfulness training has been shown to improve health and well-being in healthy individuals. 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. The COVID-19 pandemic has challenged the mental and physical health of the population. It has created intense stress both for frontline workers but also for people simply isolating at home. Mindfulness is known to decrease the psychological and physical responses to stress. So, mindfulness training may be helpful in coping with the mental and physical challenges resulting from the lockdown during the the COVID-19 pandemic.

 

In today’s Research News article “Developing Resilience During the COVID-19 Pandemic: Yoga and Mindfulness for the Well-Being of Student Musicians in Spain.” (See summary below or view the full text of the study at: (https://www.frontiersin.org/articles/10.3389/fpsyg.2021.642992/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_1616048_69_Psycho_20210504_arts_A ) Bartos and colleagues recruited Spanish college music students who enrolled in 1-hour per week mindfulness course and those who did not. The course ran from November 2019 to May 2020. In march 2020 a nationwide lockdown was initiated and the mindfulness course switched to online. The students were asked whether during Covid-19 lockdown they received psychological help, had setbacks, health changes, the nature of health changes, changes in physical, psychological, and sleep quality during the lockdown, and any practices engaged in during the lockdown and the nature of the practices.

 

They found that the students who experienced mindfulness training were significantly more likely to practice yoga and meditation to improve their health and well-being during the lockdown than the control participants. They also indicated that they received greater benefits from the practices. Almost all of the mindfulness trained participants engaged in these practices while only about a half of the control participants did.

 

It should be noted that there wasn’t random assignment of students to groups. Rather, the groups were formed by the selections of the students. This can result in different kinds of students in the two groups. It is possible that students who were likely to use yoga and meditation as coping mechanisms would be much more likely to choose to participate in a mindfulness course.

 

The Covid-19 lockdown provided a natural experiment that the researchers took advantage of to investigate the impact of mindfulness training on the students’ well-being during the lockdown. The findings support the efficacy of mindfulness training in improving the likelihood that yoga and meditation will be used as coping strategies and that these practices produce greater perceived benefits.

 

So, mindfulness training increases the use of yoga and meditation to cope with the covid-19 lockdown.

Study Summary

 

Bartos LJ, Funes MJ, Ouellet M, Posadas MP and Krägeloh C (2021) Developing Resilience During the COVID-19 Pandemic: Yoga and Mindfulness for the Well-Being of Student Musicians in Spain. Front. Psychol. 12:642992. doi: 10.3389/fpsyg.2021.642992

 

Here, we report on a quasi-experimental study to explore the applicability and perceived benefits of the CRAFT program, which is based on mindfulness, yoga, positive psychology, and emotional intelligence, to improve higher education student musicians’ health and well-being during the lockdown. A subset of student musicians at a Higher Conservatory of Music in Spain followed the CRAFT program during the academic year 2019/2020, 1 h per week as part of their curriculum. Students enrolled in CRAFT-based elective subjects formed the CRAFT program group (n = 40), while other students represented the control group (n = 53). The onset of the national lockdown elicited by the COVID-19 pandemic occurred halfway through the program, which was subsequently delivered in an online format. We administered an online survey to explore the effect that the exposure to the CRAFT program had in terms of how participants dealt with various health and well-being concerns arising from the COVID-19 lockdown. There was a significantly higher proportion of proactive participants in the CRAFT program group, 92%, than in the control group, 58%, in terms of implementing practices to improve their health and well-being during the lockdown. Additionally, significantly more participants acknowledged perceived benefits from their practices in the CRAFT program group, 78%, than in the control group, 52%. Among proactive participants, yoga/meditation was the most implemented in the CRAFT program group, followed by exercise, and other yoga/meditation practices, whereas in the control group, exercise and Alexander technique-based practices were the most applied. In the CRAFT program group, the highest rate of perceived benefits was from yoga/meditation CRAFT-based practices, 51%, followed by exercise, 32%, and other yoga/meditation practices, 27%, whereas in the control group, benefits were reported by 29% of exercising participants and 16% for those having practiced the Alexander technique. A similar pattern was observed when excluding participants with previous yoga/meditation experience. This study revealed how participants can independently apply learned skills from the CRAFT program in response to a naturally occurring life event of unprecedented global impact, suggesting that previous exposure to mindfulness and yoga is likely to have a beneficial effect on how young adults react towards exceptionally stressful conditions.

Reduce Pain and Relax the Autonomic Nervous System with Mindfulness

Reduce Pain and Relax the Autonomic Nervous System with Mindfulness

 

By John M. de Castro, Ph.D.

 

“When we impose a litany of negativity upon our pain, it only becomes worse, and potentially elicits other difficulties including depression and anxiety. When we become more aware of what we are actually experiencing, without the overlay of our judgment, the overall perception of pain is reduced.” – Jennifer Wolkin

 

We all have to deal with pain. It’s inevitable, but hopefully it’s mild and short lived. For a wide swath of humanity, however, pain is a constant in their lives. At least 100 million adult Americans have chronic pain conditions. The most common treatment for chronic pain is drugs. These include over-the-counter analgesics and opioids. But opioids are dangerous and highly addictive. Prescription opioid overdoses kill more than 14,000 people annually. So, there is a great need to find safe and effective ways to lower the psychological distress and improve the individual’s ability to cope with the pain.

 

There is an accumulating volume of research findings that demonstrate that mindfulness practices, in general, are effective in treating pain. Mindfulness appears to work by changing how the patient relates to pain rather than actually reducing or eliminating the pain. What is not known is the mechanism by which mindfulness affects chronic pain.

 

In today’s Research News article “The Role of Heart Rate Variability in Mindfulness-Based Pain Relief.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6994350/ ) Adler-Neal and colleagues recruited healthy adult non-meditators and randomly assigned them to either a meditation or sham-meditation group. The group met for 4 25-minute sessions over 7 days and practiced focused breath meditation or sham-meditation. In the sham-meditation sessions the participants were told every 2 to 3 minutes to close their eyes and take a deep breath. They were measured before and after training for respiration and heart rate variability. In addition, the participants underwent noxious non-damaging thermal stimulation on the calf of the leg and rated their pain levels.

 

They found that after both meditation and sham-meditation training there was a significant reduction in pain intensity. pain unpleasantness, and respiration rate and increase in heart rate variability, with no group differences. They also found for the meditation group only that the greater the heart rate variability the lower the pain unpleasantness ratings.

 

Heart rate variability refers to the change in the time intervals between consecutive heart beats. Higher levels of HRV are indicative of flexibility in the Autonomic Nervous System and are associated with adaptability to varying environments and lower stress levels. Higher heart rate variability is an indicator of physiological relaxation. This relaxation may well underlie the reduced pain unpleasantness. Since contemplative practices such as meditation increases heart rate variability it makes sense that these practices would also lower the perception of pain.

 

It is interesting that sham-meditation had similar effects as real meditation on pain and heart rate variability. This suggests that mindfulness reduction in pain may be due to a placebo effect where the participants’ belief that the intervention would reduce pain produced reduced perception of pain. But it could also be that the sham-meditation was actually a mindfulness practice. By focusing the participant’s attention on the breath, it might have increased mindfulness. It remains for future research to investigate this possibility.

 

So, reduce pain and relax the autonomic nervous system with mindfulness.

 

“The ancient Buddhist text called the Sullatta Sutta states that mindfulness practitioners have the ability to experience pain but then let go of it.” – Brain Tap

HIGHLIGHTS

  • Mindfulness and sham mindfulness meditation reduced pain during noxious heat
  • Mindfulness and sham mindfulness meditation increased heart rate variability (HRV)
  • Mindfulness-based pain relief was associated with higher HRV
  • Higher HRV during sham mindfulness meditation was associated with higher pain

Abstract

Mindfulness meditation is a self-regulatory practice premised on sustaining non-reactive awareness of arising sensory events that reliably reduces pain. Yet, the specific analgesic mechanisms supporting mindfulness have not been comprehensively disentangled from the potential non-specific factors supporting this technique. Increased parasympathetic nervous system (PNS) activity is associated with pain relief corresponding to a number of cognitive manipulations. However, the relationship between the PNS and mindfulness-based pain attenuation remains unknown. The primary objective of the present study was to determine the role of high frequency heart rate variability (HF HRV), a marker of PNS activity, during mindfulness-based pain relief as compared to a validated, sham-mindfulness meditation technique that served as a breathing-based control. Sixty-two healthy volunteers (31 females; 31 males) were randomized to a four-session (25 minutes/session) mindfulness or sham-mindfulness training regimen. Before and after each group’s respective training, participants were administered noxious (49°C) and innocuous (35°C) heat to the right calf. HF HRV and respiration rate were recorded during thermal stimulation and pain intensity and unpleasantness ratings were collected after each stimulation series. The primary analysis revealed that during mindfulness meditation, higher HF HRV was more strongly associated with lower pain unpleasantness ratings when compared to sham-mindfulness meditation (B = −0.82, p = 0.04). This finding is in line with the prediction that mindfulness-based meditation engages distinct mechanisms from sham-mindfulness meditation to reduce pain. However, the same prediction was not confirmed for pain intensity ratings (B = −0.41). Secondary analyses determined that mindfulness and sham-mindfulness meditation similarly reduced pain ratings, decreased respiration rate, and increased HF HRV (between group ps < 0.05). More mechanistic work is needed to reliably determine the role of parasympathetic activation in mindfulness-based pain relief as compared to other meditative techniques.

Meditation Changes the Brain Areas Underlying Executive Function and Mind Wandering

Meditation Changes the Brain Areas Underlying Executive Function and Mind Wandering

 

By John M. de Castro, Ph.D.

 

“meditation nurtures the parts of the brain that contribute to well-being. Furthermore, it seems that a regular practice deprives the stress and anxiety-related parts of the brain of their nourishment.” – Mindworks

 

Mindfulness 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. There are a number of ways that mindfulness practices produce these benefits, including changes to the brain and physiology. The nervous system is a dynamic entity, constantly changing and adapting to the environment. It will change size, activity, and connectivity in response to experience. These changes in the brain are called neuroplasticity. Over the last decade neuroscience has been studying the effects of contemplative practices on the brain and has identified neuroplastic changes in widespread areas. In other words, mindfulness practice appears to mold and change the brain, producing psychological, physical, and spiritual benefits.

 

In today’s Research News article “Resting State Functional Connectivity Associated With Sahaja Yoga Meditation.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8007769/ )  Barrós-Loscertales and colleagues recruited healthy adult non-meditators and long-term practitioners of Sahaja Yoga Meditation. They were measured for impulsiveness and cognitive control and response inhibition with a go/no-go task in which the participants had to respond to a target stimulus and withhold responding to another stimulus and a Simon task in which they had to respond to a target stimulus pointing in the same direction as its location and withhold responding to another stimulus pointing in a different direction than its location. The participants also had their brains scanned with functional Magnetic Resonance Imaging (fMRI).

 

They found that the meditators had increased functional connectivity between the ventrolateral prefrontal cortex and the dorsolateral prefrontal cortex and decreased functional connectivity between the left insula and mid-cingulate cortex and between the right angular gyrus and precuneus. They also found that the meditators had significantly less response interference and the greater the amount of response interference the lower the functional connectivity between the left insula and the mid-cingulate.

 

The ventrolateral prefrontal cortex and the dorsolateral prefrontal cortex have been found to be involved in attention, cognitive control, and conflict resolution. The increased connectivity suggests that the meditators had higher levels of executive function. The insula, cingulate cortex, angular gyrus, and precuneus are all components of the default mode network that has been shown to be involved with mind wandering and self-referential thinking. The decreased functional connectivity between these areas suggests reductions in these processes.

 

It should be kept in mind that the meditation and non-meditation groups self-selected whether they meditated or not and thus may be systematically different people. So, causation cannot be determined. Nevertheless, these results suggest that the meditators had more active attention and executive control networks and less active mind-wandering networks. These results replicate previous research that demonstrated that contemplative practices like meditation produce improvements in cognition and reductions in mind wandering.  So, the connectivity differences seen in the present study appear to show the neural mechanisms underlying the differences in thought processes.

 

So, meditation changes the brain areas underlying executive function and mind wandering.

Study Summary

Abstract

Neuroscience research has shown that meditation practices have effects on brain structure and function. However, few studies have combined information on the effects on structure and function in the same sample. Long-term daily meditation practice produces repeated activity of specific brain networks over years of practice, which may induce lasting structural and functional connectivity (FC) changes within relevant circuits. The aim of our study was therefore to identify differences in FC during the resting state between 23 Sahaja Yoga Meditation experts and 23 healthy participants without meditation experience. Seed-based FC analysis was performed departing from voxels that had shown structural differences between these same participants. The contrast of connectivity maps yielded that meditators showed increased FC between the left ventrolateral prefrontal cortex and the right dorsolateral prefrontal cortex but reduced FC between the left insula and the bilateral mid-cingulate as well as between the right angular gyrus and the bilateral precuneus/cuneus cortices. It thus appears that long-term meditation practice increases direct FC between ventral and dorsal frontal regions within brain networks related to attention and cognitive control and decreases FC between regions of these networks and areas of the default mode network.

Improve Hypertension with Mindfulness Training

Improve Hypertension with Mindfulness Training

 

By John M. de Castro, Ph.D.

 

“Several practices that help calm the mind can also lower blood pressure. All are types of meditation, which use different methods to reach a state sometimes described as “thoughtful awareness” or “restful alertness.” – Harvard Health

 

High Blood Pressure (Hypertension) is an insidious disease because there are no overt symptoms. The individual feels fine. But it can be deadly as more than 360,000 American deaths, roughly 1,000 deaths each day, had high blood pressure as a primary or contributing cause. In addition, hypertension markedly increases the risk heart attack, stroke, heart failure, and kidney disease.  It is also a very common disorder with about 70 million American adults (29%) having high blood pressure and only about half (52%) of people with high blood pressure have their condition under control. Treatment frequently includes antihypertensive drugs. But these medications often have adverse side effects. So, patients feel lousy when taking the drugs, but fine when they’re not. So, compliance is a major issue with many patients not taking the drugs regularly or stopping entirely.

 

Obviously, there is a need for alternatives to drugs for reducing blood pressure. Mindfulness practices have been shown to aid in controlling hypertension. There has accumulated a body of research on the ability of Mindfulness practices to affect hypertension. So, it makes sense to summarize what has been learned.

 

In today’s Research News article “Is Mindfulness-Based Stress Reduction Effective for People with Hypertension? A Systematic Review and Meta-Analysis of 30 Years of Evidence.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8000213/ ) Conversano and colleagues review, summarize and perform a meta-analysis of the published research studies of the effectiveness of mindfulness training on hypertension. They identified 6 published studies that employed either Mindfulness-Based Stress Reduction (MBSR) (3 studies), Mindfulness-Based Cognitive Therapy (MBCT) (2 studies), and mindfulness meditation (1 study).

 

They report that the published research found that mindfulness training improved hypertension with reductions in both systolic and diastolic blood pressure. They further report that mindfulness training worked best when the number of patients taking antihypertensive drugs were low, with the lower the percentage of participants on antihypertensive drugs, the greater the effect size of mindfulness training on hypertension.

 

These are impressive results that suggest that mindfulness training is a safe and effective treatment for hypertension. The trainings appear to work best in the absence of drugs to control hypertension. It follows that mindfulness training would reduce the physical effects of hypertension and thereby improve the overall health and longevity of the patients.

 

So, improve hypertension with mindfulness training.

 

“The hope is that if we can start mindfulness training early in life, we can promote a trajectory of healthy aging across the rest of people’s lives. That will reduce their chances of getting high blood pressure in the first place.” – Eric Loucks

Abstract

Background: Hypertension is among the most important risk factors for cardiovascular diseases, which are considered high mortality risk medical conditions. To date, several studies have reported positive effects of mindfulness-based stress reduction (MBSR) interventions on physical and psychological well-being in other medical conditions, but no meta-analysis on MBSR programs for hypertension has been conducted. Objectives: The objective of this study was to determine the effectiveness of MBSR programs for hypertension. Methods: A systematic review and meta-analysis of randomized controlled trials examining the effects of MBSR on systolic and diastolic blood pressure (BP), anxiety, depression, and perceived stress in people with hypertension or pre-hypertension was conducted. The PubMed/MEDLINE and PsycINFO databases were searched in November 2020 to identify relevant studies. Results: Six studies were included. The comparison of MBSR versus control conditions on diastolic BP was associated with a statistically significant mean effect size favoring MBSR over control conditions (MD = −2.029; 95% confidence interval (CI): −3.676 to −0.383, p = 0.016, k = 6; 22 effect sizes overall), without evidence of heterogeneity (I2 = 0.000%). The comparison of MBSR versus control conditions on systolic BP was associated with a mean effect size which was statistically significant only at a marginal level (MD = −3.894; 95% CI: −7.736–0.053, p = 0.047, k = 6; 22 effect sizes overall), without evidence of high heterogeneity (I2 = 20.772%). The higher the proportion of participants on antihypertensive medications was, the larger the effects of MBSR were on systolic BP (B = −0.750, z = −2.73, p = 0.003). Conclusions: MBSR seems to be a promising intervention, particularly effective on the reduction of diastolic BP. More well-conducted trials are required.

Improve Attention in Older Individuals with Exercise and Mindfulness

Improve Attention in Older Individuals with Exercise and Mindfulness

 

By John M. de Castro, Ph.D.

 

“engaging in mindfulness meditation training improves the maintenance of goal-directed visuospatial attention and may be a useful strategy for counteracting cognitive decline associated with aging.” – Peter Malinowski

 

One of the primary effects of mindfulness training is an improvement in the ability to pay attention to the task at hand and ignore interfering stimuli. This is an important consequence of mindfulness training and produces improvements in thinking, reasoning, and creativity. The importance of heightened attentional ability to the individual’s ability to navigate the demands of complex modern life cannot be overstated. It helps in school, at work, in relationships, or simply driving a car. As important as attention is, it’s surprising that little is known about the mechanisms by which mindfulness improves attention

 

There is evidence that mindfulness training improves attention by altering the brain. It appears That mindfulness training increases the size, connectivity, and activity of areas of the brain that are involved in paying attention. A common method to study the activity of the nervous system is to measure the electrical signal at the scalp above brain regions. Changes in this activity are measurable with mindfulness training.

 

One method to observe attentional processing in the brain is to measure the changes in the electrical activity that occur in response to specific stimuli. These are called event-related, or evoked, potentials or ERPs. The signal following a stimulus changes over time. The fluctuations of the signal after specific periods of time are thought to measure different aspects of the nervous system’s processing of the stimulus. The N2 response in the evoked potential (ERP) is a negative going electrical response occurring between a 1 to 3 tenths of a second following the target stimulus presentation. The N2 component is thought to reflect cognitive control. The P3 response is a positive going electrical response occurring between a 3 to 6 tenths of a second following the target. The P3 component is thought to reflect attentional processing.

 

In today’s Research News article “Behavioral and ERP Correlates of Long-Term Physical and Mental Training on a Demanding Switch Task.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7940199/ ) Burgos and colleagues recruited healthy adults aged 44-65 years. They were separated into groups of participants who practiced for at least 5 years either Tai Chi, Meditation, aerobic exercise, meditation and exercise, or were sedentary. The participants performed a visuospatial task switch test that required the participants to respond to the position of a dot on a screen with the same or opposite hand or to switch back and forth between the two after 2 trials. This measures executive attention. As they were performing the task the electroencephalogram (EEG) was recorded and the evoked potentials to the dot recorded.

 

They found that on the visuospatial task switch test the Tai Chi and Meditation plus exercise groups performed best, the aerobic exercise group intermediate, and the sedentary group worst. Performance was measured by the reaction times on the switch trials and also on the proportionate change in reaction times on switch trials. In the evoked potentials in the frontal and parietal cortical areas, the groups that had mental plus physical training (Tai Chi and Meditation plus exercise groups) had significantly larger N2 responses on switch trials than the meditation or exercise alone groups. They also found that the larger the N2 response the better the performance on the switch task.

 

These are interesting results. But the groups were composed of people who chose to engage in these differing activities and the groups may be composed of people who differ in other ways other than the chosen activity. It would be best in future research if random assignment and training were used. Nevertheless, the results suggest that executive attention is best in people who practice mental and physical exercises. These are superior to either alone and particularly superior to being sedentary.  It was not studied here, but the better performance in attentional ability would predict better overall performance in life and resistance to the mental decline with aging.

 

Both the performance on the task and the N2 responses reflect better executive control of attention. This means that the participants who performed both mindfulness and physical exercise improved their ability to control attention. Mindfulness practices such as Tai Chi and meditation are known to alter the brain and improve attention. But the reason why exercise supplements these benefits is unknown. It is possible that exercise isn’t responsible for improvement but that sedentariness is responsible for deterioration and exercise acts to prevent this deterioration. Nevertheless, the results are clear mindfulness plus physical activity alters the brain in such a way as to improve the individual’s ability to control attention.

 

So, improve attention in older individuals with exercise and mindfulness.

Abstract

Physical and mental training are associated with positive effects on executive functions throughout the lifespan. However, evidence of the benefits of combined physical and mental regimes over a sedentary lifestyle remain sparse. The goal of this study was to investigate potential mechanisms, from a source-resolved event-related-potential perspective, that could explain how practicing long-term physical and mental exercise can benefit neural processing during the execution of an attention switching task. Fifty-three healthy community volunteers who self-reported long-term practice of Tai Chi (n = 10), meditation + exercise (n = 16), simple aerobics (n = 15), or a sedentary lifestyle (n = 12), aged 47.8 ± 14.6 (SD) were included in this analysis. All participants undertook high-density electroencephalography recording during a switch paradigm. Our results indicate that people who practice physical and mental exercise perform better in a task-switching paradigm. Our analysis revealed an additive effect of the combined practice of physical and mental exercise over physical exercise only. In addition, we confirmed the participation of frontal, parietal and cingulate areas as generators of event-related-potential components (N2-like and P3-like) commonly associated to the performance of switch tasks. Particularly, the N2-like component of the parietal and frontal domains showed significantly greater amplitudes in the exercise and mental training groups compared with aerobics and sedentary groups. Furthermore, we showed better performance associated with greater N2-like amplitudes. Our multivariate analysis revealed that activity type was the most relevant factor to explain the difference between groups, with an important influence of age, and body mass index, and with small effects of educational years, cardiovascular capacity, and sex. These results suggest that chronic combined physical and mental training may confer significant benefits to executive function in normally aging adults, probably through more efficient early attentional processing. Future experimental studies are needed to confirm our results and understand the mechanisms on parieto-frontal networks that contribute to the cognitive improvement associated with practicing combined mental and aerobic exercise, while carefully controlling confounding factors, such as age and body mass index.

Increase the Energy Metabolism of the Brain with Meditation

Increase the Energy Metabolism of the Brain with Meditation

 

By John M. de Castro, Ph.D.

 

“As a form of mental training, meditation improves core physical and psychological assets, including energy, motivation, and strength. Studies on the neurophysiological concomitants of meditation have proved that commitment to daily practice can bring promising changes for the mind and the body.” –  Madhuleena Roy Chowdhury

 

Mindfulness training has been shown through extensive research to be effective in improving physical and psychological health and particularly with reducing the physical and psychological reactions to stress. There are a number of ways that meditation practices produce these benefits, including changes to the brain and physiology. The nervous system changes in response to how it is used and how it is stimulated in a process called neuroplasticity. Highly used areas grow in size, metabolism, and connectivity. Mindfulness practices in general are known to produce these kinds of changes in the structure and activity of the brain.

 

In today’s Research News article “Short-term meditation training influences brain energy metabolism: A pilot study on 31 P MR spectroscopy.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7821578/ ) Gizewski and colleagues recruited healthy adult meditation naïve yoga students and provided them with 7 weeks of twice a week 45-minute training in Raja yoga meditation. This focused meditation training emphasizes the cessation of thinking and includes meditation and breathing exercises. They were measured before and after training for meditative depth, health history, lifestyle, anxiety, depression, and angst. Before and after training they also underwent brain scanning with structural Magnetic Resonance Imaging (MRI) and for brain energy metabolism (31P-MRS).

 

They found that in comparison to baseline after Raja yoga meditation training there were significant increases overall mental health and decreases in anxiety and dysthymia. There were also significant increases in brain energy metabolism particularly in the right hemisphere in the occipital and temporal lobes and the basal ganglia.

 

This study did not contain a comparison, control, condition which opens the results up to some alternative interpretations. But ignoring these possible contaminants, the study suggests that 7 weeks of meditation training can alter the brain. This has been demonstrated with numerous studies of changes in the structure, connectivity, and electrical activity of the brain produced by mindfulness training. The present study adds to this understanding by demonstrating the focused meditation training increases the energy metabolism in the brain particularly in the posterior cerebral cortex and the motor control areas. Meditation training is thought to be relaxing and the technique used here is one that emphasizes reduction in mental activity. But the present study suggests that the brain can get very active. This suggests that there is considerable mental activity going on during meditation.

 

So, increase the energy metabolism of the brain with meditation.

 

“Meditation is thought to work via its effects on the sympathetic nervous system, which increases heart rate, breathing, and blood pressure during times of stress. Yet meditating has a spiritual purpose, too. “True, it will help you lower your blood pressure, but so much more: it can help your creativity, your intuition, your connection with your inner self,” –  Burke Lennihan,

Short-term meditation training influences brain energy metabolism: A pilot study on 31 P MR spectroscopy. Brain and behavior, 11(1), e01914. https://doi.org/10.1002/brb3.1914

 

Abstract

Background

Meditation is increasingly attracting interest among neuroimaging researchers for its relevance as a cognitive enhancement technique and several cross‐sectional studies have indicated cerebral changes. This longitudinal study applied a distinct and standardized meditative technique with a group of volunteers in a short‐term training program to analyze brain metabolic changes.

Methods

The effect of 7 weeks of meditation exercises (focused attention meditation, FAM) was assessed on 27 healthy volunteers. Changes in cerebral energy metabolism were investigated using 31P‐MR spectroscopy. Metabolite ratios were compared before (T1) and after training (T2). Additional questionnaire assessments were included.

Results

The participants performed FAM daily. Depression and anxiety scores revealed a lower level of state anxiety at T2 compared to T1. From T1 to T2, energy metabolism ratios showed the following differences: PCr/ATP increased right occipitally; Pi/ATP decreased bilaterally in the basal ganglia and temporal lobe on the right; PCr/Pi increased in occipital lobe bilaterally, in the basal ganglia and in the temporal lobe on the right side. The pH decreased temporal on the left side and frontal in the right side. The observed changes in the temporal areas and basal ganglia may be interpreted as a higher energetic state, whereas the frontal and occipital areas showed changes that may be related to a down‐regulation in ATP turnover, energy state, and oxidative capacity.

Conclusions

The results of the current study indicate for the first time in a longitudinal study that even short‐term training in FAM may have considerable effects on brain energy state with different local energy management in specific brain regions. Especially higher energetic state in basal ganglia may represent altered function in their central role in complex cerebral distributed networks including frontal and temporal areas. Further studies including different forms of relaxation techniques should be performed for more specific and reliable insights.
