Reduce Body Mass and Improve Body Composition in the Overweight Young Women with Yoga

 

By John M. de Castro, Ph.D.

 

“The purpose of exercise interventions should be to help youth with obesity find alternatives that increase their engagement with activity, and thus lead to more sustainable changes in lifestyle. Yoga practice is an excellent example of how to use more nontraditional approaches to engage students with exercise.” – Sarah Shultz

 

Obesity has become an epidemic in the industrialized world. In the U.S. the incidence of obesity, defined as a Body Mass Index (BMI) of 30 or above has more than doubled over the last 35 years to currently around 35% of the population, while two thirds of the population are considered overweight or obese (BMI > 25). Sadly, children and adolescents have not been spared with 1 in 5 school age children and young people (6 to 19 years) classified as obese.

 

Obviously, there is a need for effective treatments to prevent or treat obesity. But, despite copious research and a myriad of dietary and exercise programs, there still is no safe and effective treatment. Mindfulness is known to be associated with lower risk for obesity, alter eating behavior and improve health in obesity. This suggests that mindfulness training may be an effective treatment for overeating and overweight alone or in combination with other therapies. Yoga practice has been shown to have a myriad of physical and psychological benefits. These include significant loss in weight and body mass index (BMI), resting metabolism, and body fat and improve health in the obese.

 

In today’s Research News article “Effects of Continuous Yoga on Body Composition in Obese Adolescents.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8410386/ ) Nongkhai and colleagues recruited overweight (BMI 23-29.5) young women (age 19-22 years) and randomly assigned them to either engage in continuous yoga practice 3 times per week for 50 minutes for 12 weeks or to a no treatment control condition. The yoga practice was designed to increase and maintain aerobic exercise levels (65% – 75% of maximum heart rate). Before, at the midpoint, and after training they were measured for body size and composition.

 

They found that in comparison to baseline and the control group the yoga group had significant decreases in their Body Mass Index (BMI) and body fat mass. While the control group had a significant decrease in muscle mass, the yoga group maintained their muscle mass. Hence, participation in yoga had positive body size and composition benefits for overweight young women.

 

In the present study, the intervention was a yoga practice that elevated and maintained aerobic levels. This makes it impossible to discern if the benefits were due to yoga per se or to the exercise. Nevertheless, these results to some extent replicate previous findings that yoga practice improves weight and body composition. Future research should contain a non-yoga aerobic exercise group. Regardless, it is clear that engaging in continuous yoga is improves the body size and composition of young women.

 

So, reduce body mass and improve body composition in the overweight young women with yoga.

 

“Yoga practice works to expand consciousness of overall health and well being.  . . . many children and teens dealing with obesity who find a safe place in yoga to cultivate a positive sense of self that contributes to confidence.” – Abby Wills

Abstract

Overweight/obesity is a pressing international health concern, and conventional treatments demonstrate poor long-term efficacy. Several studies have shown that yoga can control risk factors for cardiovascular disease, obesity, and psychosocial stress. The present study aimed to assess the effect of continuous yoga (asanas, pranayama, and Surya Namaskar yoga) on body composition in overweight participants. Forty adolescents with obesity were enrolled in this study. The study was conceived as a prospective, single-center, single-blinded randomized controlled trial. The participants were divided into 2 groups: the intervention group (n = 20), which undertook a continuous yoga practice, and the control group (n = 20). Body composition, including body weight (BW), body mass index (BMI), body fat mass (BFM), and muscle mass, was evaluated using tetrapolar bioelectrical impedance (BIA). Our results showed that the mean BMI and BFM of the yoga intervention group were significantly decreased at week 8 and week 12. The muscle mass of the yoga group continued to improve at a rate of 0.515 per week, which was statistically significant. In conclusion, a continuous yoga practice had a tendency to decrease BMI and BFM and increase muscle mass. These findings demonstrate intervention effectiveness similar to that observed in other clinical research and indicate that continuous yoga practice may be used as an alternative therapy for obesity prevention and health promotion in adolescents with obesity.

Reduce Stress and Improve Sleep and Cognition with Yoga

 

By John M. de Castro, Ph.D.

 

“yoga can improve your sleep, increase mindfulness, relieve anxiety and even help you stick to healthy habits in other aspects of your life.” – Corey Stieg

 

Modern society has become more around-the-clock and more complex producing considerable pressure and stress on the individual. The advent of the internet and smart phones has exacerbated the problem. The resultant stress can impair sleep. Indeed, it is estimated that over half of Americans sleep too little due to stress. As a result, people today sleep 20% less than they did 100 years ago. Not having a good night’s sleep has adverse effects upon the individual’s health, well-being, and happiness. It has been estimated that 30 to 35% of adults have brief symptoms of insomnia, 15 to 20% have a short-term insomnia disrder, and 10% have chronic insomnia. These sleep problems can interfere with cognitive functions.

 

Mindfulness-based practices including yoga practice have been reported to improve sleep amount and quality and help with insomnia, to reduce stress, and improve cognitive function. The research is accumulating. So, it makes sense to step back and summarize what has been learned about the effects of yoga practice on stress, sleep, and cognition.

 

In today’s Research News article “Sleep, Cognition, and Yoga.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8191228/ ) Panjwani and colleagues review and summarize the published research studies on the effects of yoga practice on stress, sleep, and cognition.

 

They report that the published research studies found that yoga practice improved sleep quality, sleep architecture and mental well-being in adults and the elderly. It also improved sleep in individuals with sleep disorders such as sleep apnea. In addition, they report that yoga produces improvement in cognitive function, mood, and stress in healthy adults and reduces cognitive decline in the elderly.

 

Hence, the published research demonstrates that yoga practice is beneficial for sleep, cognition, and mental well-being in adults and the elderly. This suggests that yoga practice should be incorporated into the individual’s lifestyle during their adult life and into their golden years.

 

So, reduce stress and improve sleep and cognition with yoga.

 

“A national survey found that over 55% of people who did yoga found that it helped them get better sleep. Over 85% said yoga helped reduce stress.” – Marlyn Wei

Abstract

Stress is one of the major problems globally, associated with poor sleep quality and cognitive dysfunction. Modern society is plagued by sleep disturbances, either due to professional demands or lifestyle or both the aspects, often leading to reduced alertness and compromised mental function, besides the well documented ill effects of disturbed sleep on physiological functions. This pertinent issue needs to be addressed. Yoga is an ancient Indian science, philosophy and way of life. Recently, yoga practice has become increasingly popular worldwide. Yoga practice is an adjunct effective for stress, sleep and associated disorders. There are limited well controlled published studies conducted in this area. We reviewed the available literature including the effect of modern lifestyle in children, adolescents, adults and geriatric population. The role of yoga and meditation in optimizing sleep architecture and cognitive functions leading to optimal brain functioning in normal and diseased state is discussed. We included articles published in English with no fixed time duration for literature search. Literature was searched mainly by using PubMed and Science Direct search engines and critically examined. Studies have revealed positive effects of yoga on sleep and cognitive skills among healthy adults as well as patients of some neurological diseases. Further, on evaluating the published studies, it is concluded that sleep and cognitive functions are optimized by yoga practice, which brings about changes in autonomic function, structural changes, changes in metabolism, neurochemistry and improved functional brain network connectivity in key regions of the brain.

Increase Brain Activity with Brief Exercise and Meditation

Increase Brain Activity with Brief Exercise and Meditation

 

By John M. de Castro, Ph.D.

 

“Meditating for a few minutes might help rein in those wandering thoughts and help you stay focused throughout the day. But meditating can have an even bigger impact. Some studies show that it affects the brain in various ways, from changing the brain’s volume to decreasing activity in the parts of the brain responsible for stress.” – Lela Moore

 

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. One way to observe the effects of meditation on the nervous system is to measure changes in the functional near‐infrared spectroscopy (fNIRS), which measures blood flow to brain areas.

 

In today’s Research News article “Activation of the orbitofrontal cortex by both meditation and exercise: A near-infrared spectroscopy study.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7901739/ ) Miyashiro and colleagues recruited healthy adults and had them perform 20 minutes of breath following meditation, exercise (pushups), or a control task (movie of scenery with relaxing music) in a random order. They then performed a 2-back test of attention involving presentation of a sequence of numbers and after a prompt, the recall of the number 2 places back. While performing this task the participants underwent measurement of brain activation with functional near‐infrared spectroscopy (fNIRS).

 

They did not observe a significant difference between groups on the 2-back test. But in comparison to the control condition, the meditation and exercise groups had significantly increased activation of the edges of the orbitofrontal cortex (insular cortex) that then spread to the central orbitofrontal cortex. The 20-minute interventions were too short to invoke neuroplasticity and produce long-lasting changes in this brain. The orbitofrontal cortex is known to be involved in attention. So, it is not surprising that attention demanding exercise and meditation would alter its activity while the plotless video would invoke mind wandering and a loss of attention.

 

So, increase brain activity with brief exercise and meditation.

Abstract

In some types of meditation, such as mindfulness and Zen, breathing is the focus of attention, whereas during an excessive, short-period of anaerobic exercise, the muscles become the focus of attention. Thus, during both efforts, one’s attention is focused on a certain feature of the body. Both meditation and exercise generally provide mental refreshment to humans. We hypothesized that the same brain regions are activated by both efforts in humans. To examine this hypothesis, we engaged participants in 3 tasks: meditation, exercise, and a control task. After each task, the participants underwent a 2-back test to concentrate their thoughts, while changes in their blood hemoglobin levels were simultaneously monitored using near-infrared spectroscopy (NIRS). Seventeen participants (20–24 years of age; 11 men, 6 women) were enrolled. We applied a fast-Fourier transform (FFT) analysis to the NIRS wave data and calculated the correlation coefficients of the FFT data between (1) meditation and control, (2) exercise and control, and (3) meditation and exercise, at the orbitofrontal cortex (OFC) and dorsolateral prefrontal cortex (DLPFC), brain areas that are generally involved in mental refreshment. A significant difference in the correlation coefficients between the OFC and DLPFC was detected in the meditation and exercise analysis, and signal source analysis confirmed that the NIRS waves spread from the right and left OFC edges (i.e., right and left temples) toward the center. Our results suggest that both meditation and exercise activate the OFC, which is involved in emotional reactions and motivation behavior, resulting in mental refreshment.

Improve Working Memory and Increase Brain Activity with a Single Focused Meditation in Novice Meditators

Improve Working Memory and Increase Brain Activity with a Single Focused Meditation in Novice Meditators

 

By John M. de Castro, Ph.D.

 

“Regular meditation increases blood flow to the brain, which leads to a stronger network of blood vessels in the cerebral cortex and reinforces memory capacity.” – Mindworks

 

Humans have both an amazing capacity to remember and a tremendously limited capacity depending upon which phase of the memory process. Our long-term store of information is virtually unlimited. On the other hand, short-term memory is extremely limited. This is called our working memory and it can contain only about 5 to 9 pieces of information at a time. This fact of a limited working memory store shapes a great deal about how we think, summarize, and categorize our world.

 

Memory ability is so important to everyday human functioning that it is important to study ways to maintain or improve it. Mindfulness has been shown to improve working memory capacity. Since the brain is responsible for working memory, the effects of mindfulness training on working memory must in some way be altering the brain. One way to observe the effects of meditation on the nervous system is to measure changes in the functional near‐infrared spectroscopy (fNIRS), which measures blood flow to brain areas. Hence, it makes sense to observe the effects of meditation on working memory and its association with cerebral flows.

 

In today’s Research News article “Effect of one-session focused attention meditation on the working memory capacity of meditation novices: A functional near-infrared spectroscopy study.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8413779/ ) Yamaya and colleagues recruited adult meditation naïve university students and randomly assigned them to practice for 15 minutes focused breath following meditation or listen to disconnected random conversations. During the 15-minute intervention period cerebral blood flow was measured with functional near‐infrared spectroscopy (fNIRS). They were also measured 5 minutes before and 5 minutes after the 15-minute intervention period for working (short-term) memory.

 

They found that in comparison to baseline and the random thinking control group, the group that performed focused meditation had a significant increase in working memory capacity and a significant increase in cerebral blood flow to the dorsolateral prefrontal cortex. They found that the working memory change and the cerebral blood flow change were significantly correlated such that the greater the increase in cerebral blood flow, the greater the increase in working memory.

 

The results are interesting that a single 15-minute meditation by meditation naïve participants immediately increases working memory. The results further suggest that this memory improvement is associated with an increase in the flow of blood to a particular brain area, the dorsolateral prefrontal cortex, that has been shown to be involved in focused attention. This suggests that focused meditation activates the dorsolateral prefrontal cortex which improves working memory.

 

The very short-term nature of the study precludes any neuroplastic changes in the brain. But previous research has found that longer-term meditation produces long-term changes in the dorsolateral prefrontal cortex. It is unfortunate that in the present study there wasn’t a follow up to determine if the effects of the single 15-minute meditation were immediate and transitory or persisted for a period of time. Regardless, the results may provide a glimpse as to how meditation changes brain systems and in turn memory.

 

So, improve working memory and increase brain activity with a single focused meditation in novice meditators.

Effect of one-session focused attention meditation on the working memory capacity of meditation novices: A functional near-infrared spectroscopy study. Brain and behavior, 11(8), e2288. https://doi.org/10.1002/brb3.2288

 

Abstract

Introduction

Previous studies have revealed that one‐session focused attention meditation (FAM) can improve top‐down attention control, which is one of the factors of working memory capacity (WMC). In addition, FAM shares various neural substrates, including the dorsolateral prefrontal cortex (DLPFC), with WMC. Thus, we hypothesized that one‐session FAM would improve WMC by activating the DLPFC evoked by the top‐down attention control. In this study, we examined whether FAM modified WMC in individuals with little to no meditation experience.

Methods

The participants were randomly assigned to either the FAM group (N = 13) or the control group (N = 17) who engaged in random thinking (i.e., mind‐wandering). Before and after each 15‐min intervention, the participants’ WMC was measured according to the total number of correct answers in the Reading Span Test. During each intervention, functional near‐infrared spectroscopy was employed to measure the blood flow in the participants’ DLPFC and determine the top‐down attention control effect.

Results

In the FAM group, WMC increased, and the bilateral DLPFC was activated during the intervention. As for the control group, WMC decreased after the intervention, and the bilateral DLPFC was not activated during the intervention. A correlation was also found among all participants between the increase in WMC and the activation of the bilateral DLPFC.

Conclusion

The study findings suggest that top‐down attention control during FAM can activate the bilateral DLPFC and increase WMC among meditation novices.

Combined Meditation, Yoga, and Ethical Education have Additive Effects on Well-Being

Combined Meditation, Yoga, and Ethical Education have Additive Effects on Well-Being

 

By John M. de Castro, Ph.D.

 

“When practiced together, yoga and meditation strengthen the connection between mind and body, thereby improving overall fitness and wellbeing.” – Peaceful Dragon

 

Mindfulness training has been shown to improve health and well-being in healthy individuals and those with medical and psychiatric conditions, Similarly, yoga practice has been shown to improve health and well-being in healthy individuals and those with medical and psychiatric conditions.  Meditation practice is known to decrease the psychological and physical responses to stress. Similarly, yoga practice has been shown to decrease the psychological and physical responses to stress. But there has been little research of the impact of combining meditation and yoga practices.

 

In today’s Research News article “Differential Effects of Ethical Education, Physical Hatha Yoga, and Mantra Meditation on Well-Being and Stress in Healthy Participants-An Experimental Single-Case Study.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8375679/ ) Matko and colleagues recruited healthy adult participants who did not practice meditation or yoga and randomly assigned them to one of 4 treatment conditions once a week for 8 weeks; mantra meditation alone, mantra meditation plus physical yoga, mantra meditation plus ethical education, and mantra meditation plus physical yoga and ethical education. They were also instructed to practice daily at home. They were measured weekly before and after training and 8 weeks and 12 months later for well-being, perceived stress, and life satisfaction and a daily home practice questionnaire.

 

They found that all conditions produced significant improvements in well-being, but the combined treatments produced greater improvements than mantra meditation alone with those that contained ethical education having the greatest benefits. All conditions produced equivalent significant increases in life satisfaction.

 

The results suggest that engaging in mindfulness practices produce lasting improvements in the well-being and life satisfaction of the participants. This improved well-being and life satisfaction produced by mindfulness practices have been well documented in prior research studies. In addition, the findings suggest that adding yoga and especially ethical education to meditation amplifies the improvements in well-being. Ethical education in the present study included training and discussion of non-violence, truthfulness, non-stealing, self-restraint, non-hoarding, cleanliness, contentment, and transcendence. This appeared to have an additive effect on well-being.

 

 

There was, however, a confounding variable which is the duration of practice. Whereas the weekly trainings for mantra meditation practice took 60 minutes, mantra meditation plus physical yoga took 105 minutes, mantra meditation plus ethical education took 135 minutes, and mantra meditation plus physical yoga and ethical education took 180 minutes. In addition, each practice was practiced daily for 20 minutes with the combined conditions being practiced for 40 and 60 minutes respectively. So, the more practice the greater the improvement in well-being. Future research needs to fix the amount of practice so that the total is the same for all conditions and their combinations.

 

So, combined meditation, yoga, and ethical education have additive effects on well-being.

 

“The beauty of Yoga and Meditation, when they are merged together, helps one relish each and every moment of life. There is no place for stress and anxiety in a mind that enjoys Yoga. While Yoga poses promote blood circulation in the brain, Meditation makes sure it stays calm and composed to feel complete serenity.” – Manmohan Singhis

Abstract

Traditionally, yoga is a multicomponent practice consisting of postures, breathing techniques, meditation, mantras, and ethics. To date, only a few studies have tried to dismantle the effects of each of these components and their combinations. To fill this gap, we examined the incremental effects of ethical education and physical Hatha yoga on mantra meditation using a single-case multiple-baseline design. This study was part of a project evaluating the new mind–body program Meditation-Based Lifestyle Modification. Fifty-seven healthy participants with no regular yoga or meditation practice were randomly assigned to three baselines (7, 14, and 21 days) and four conditions using a random number generator. The conditions were mantra meditation alone (MA), meditation plus physical yoga (MY), meditation plus ethical education (ME), and meditation plus yoga and ethical education (MYE). All the interventions lasted for 8 weeks and were run consecutively according to baseline length. During the baseline and treatment phases, participants received daily questionnaires measuring their well-being (WHO-5 Well-Being Index), stress (Perceived Stress Scale), and subjective experiences. Forty-two participants completed the treatment and were entered in the analyses. We analyzed our data using visual inspection, effect size estimation (Tau-U), and multilevel modeling. Almost all participants showed a longitudinal increase in well-being. Regarding between-group differences, participants who received ethical education exhibited the largest increases in well-being (Tau-U = 0.30/0.23 for ME/MYE), followed by participants in the MY condition (Tau-U = 0.12). Conversely, participants in the MA condition showed no change (Tau-U = 0.07). There was a tendency for the combined treatments to decrease stress. This tendency was strongest in the MY condition (Tau-U = –0.40) and reversed in the MA condition (Tau-U = 0.17). These results emphasize the incremental and differential effects of practicing meditation in combination with other practices from the eight-fold yoga path. This approach is valuable for better understanding the multifaceted practice of yoga.

Reduce Stress and Increase Work Engagement with an Online Mindfulness Course

Reduce Stress and Increase Work Engagement with an Online Mindfulness Course

 

By John M. de Castro, Ph.D.

 

“When we constantly flit from one task to another, the quality of our work can suffer. By practicing mindfulness — simply coming back to the present moment over and over again — we can train ourselves to become more focused.” – David Gelles

 

Mindfulness training has been shown to greatly improve psychological health and well-being. But most mindfulness training techniques require a trained teacher. The participants must be available to attend multiple sessions at particular scheduled times that may or may not be compatible with busy employee schedules and at locations that may not be convenient. As an alternative online mindfulness trainings have been developed. These have tremendous advantages in decreasing costs, making training schedules much more flexible, and eliminating the need to go repeatedly to specific locations. But the question arises as to the effectiveness of these online courses in inducing mindfulness and reducing stress and improving psychological well-being of people who choose to participate.

 

In today’s Research News article “Mindfulness Is Associated With Lower Stress and Higher Work Engagement in a Large Sample of MOOC Participants.” (See summary below or view the full text of the study at: https://www.frontiersin.org/articles/10.3389/fpsyg.2021.724126/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_1735535_a0P58000000G0YfEAK_Psycho_20210921_arts_A ) Bartlett and colleagues employed people who spontaneously enrolled in a 3 hour per week for 6 weeks online mindfulness course that was based upon the Mindfulness-Based Stress Reduction (MBSR) Program. Before and after the course participants could volunteer to complete measures of mindfulness, perceived stress, and work engagement. 16,697 participants voluntarily completed these measures.

 

They found that the higher the levels of mindfulness the lower the levels of perceived stress and the higher the levels of work engagement including the vigor, dedication, and absorption subscales. Mindfulness was found to be associated with higher work engagement directly and indirectly by being associated with lower perceived stress that was in turn associated with higher work engagement. In comparison to baseline after the mindfulness course there were significant increases in mindfulness and work engagement and decreases in perceived stress.

 

This study employed people who voluntarily chose to take an online mindfulness course and complete questionnaires before and after the course. There was no random selection or assignment to groups. So, there are a large number of alternative, confounding, interpretations of the results. But many prior controlled research studies have demonstrated that mindfulness training produces lower perceived stress and higher work engagement and that mindfulness can be learned over the internet with similar effects to that learned with in person training. So, the present results were likely due to the effects of the online mindfulness training.

 

These results suggest that online courses freely available to anyone with an internet connection are effective in improving the well-being of the participants. The particular online mindfulness course employed in the present study has been completed by over 400,000 individuals. Hence, this course was free and widely used and was effective in improving the psychological health of the participants. This is remarkable. Online mindfulness courses allow the benefits of mindfulness training to be available free to huge numbers of people worldwide.

 

So, reduce stress and increase work engagement with an online mindfulness course.

Study Summary

 

Bartlett L, Buscot M-J, Bindoff A, Chambers R and Hassed C (2021) Mindfulness Is Associated With Lower Stress and Higher Work Engagement in a Large Sample of MOOC Participants. Front. Psychol. 12:724126. doi: 10.3389/fpsyg.2021.724126

 

Objective: This study aimed to understand the associations between mindfulness, perceived stress, and work engagement in a very large sample of English-speaking adults, from 130 different countries. It also aimed to assess participants’ self-reported changes following a 6-week mindfulness massive open online course (MOOC).

Methods: Participants in the 6-week MOOC were invited to complete pre-post online surveys. Cross-sectional associations were assessed using univariate linear models, followed by structural equation models to test mediation pathways in baseline data (N = 16,697). Self-reported changes in mindfulness, stress and engagement following training were assessed using paired t-tests (n = 2,105).

Results: Each standard deviation unit increase in mindfulness was associated with a 0.52 standard deviation unit decrease in perceived stress, and with 0.06 standard deviation unit increment in work engagement. 73% of the influence of mindfulness on engagement was direct. Following the mindfulness MOOC, participants reported higher mindfulness (d = 1.16), reduced perceived stress (d = 1.00) and a small improvement in work engagement (d = 0.29).

Conclusions: Mindfulness was associated with lower perceived stress and higher work engagement in both cross-sectional and longitudinal analyses. These findings support mindfulness as a potentially protective and modifiable personal resource. The MOOC format offers a low cost, highly accessible means for extending the reach and potential benefits of mindfulness training to large numbers of people.

Spirituality (Meaningfulness) is Related to Lower Work Burnout

 

By John M. de Castro, Ph.D.

 

“the use of spiritual beliefs and practices can reduce the effects of burnout.” – Andrew Jacob Godoy

 

Stress is epidemic in the western workplace with almost two thirds of workers reporting high levels of stress at work. Burnout is the fatigue, cynicism, emotional exhaustion, sleep disruption, and professional inefficacy that comes with work-related stress. Religion and spirituality have been promulgated as solutions to the challenges of life. There have been a number of studies of the influence of religiosity and spirituality on the physical and psychological well-being of practitioners mostly showing positive benefits, with spirituality encouraging personal growth and mental health. Spirituality may be viewed as a search for meaning in one’s life. Hence, there is a need to investigate the relationships of spirituality (meaningfulness) with burnout in work environments.

 

In today’s Research News article “An Empirical Investigation of the Relationship Between Spirituality, Work Culture, and Burnout: The Need for an Extended Health and Disease Model.” (See summary below or view the full text of the study at: https://www.frontiersin.org/articles/10.3389/fpsyg.2021.723884/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_1735535_a0P58000000G0YfEAK_Psycho_20210921_arts_A ) Listopad and colleagues recruited employed adults online and had them complete measures of burnout, work engagement, meaningfulness of work, and homeliness in the organization. They operationally define spirituality as meaningfulness which in this study translates to meaningfulness of work.

 

They found that the lower the levels of work engagement, meaningfulness of work, and homeliness the greater the level of burnout. They also found that the subscales of the meaningfulness of work measure were negatively related to burnout especially positive meaning of work and were also positively related to work engagement. Additionally, they found that the subscales of the homeliness in the organization measure were negatively related to burnout especially needs fulfillment, group membership, and emotional connection and were also positively related to work engagement.

 

The study is correlative and as such caution must be exercised in reaching conclusions regarding causation. Nevertheless, the results demonstrate that spirituality (meaningfulness) is related to lower burnout. The results suggest that greater meaningfulness of work (spirituality) and t connection of the worker to the organization (homeliness) the lower the levels of burnout and the higher the levels of engagement in the work. The search for meaning (spirituality) is ubiquitous in humans. Hence, in part, burnout is more likely to occur when there is a lack of meaningfulness. When meaning is missing it is more likely that work will unsatisfying and burnout can occur.

 

So, spirituality (meaningfulness) is related to lower work burnout.

Study Summary

 

Listopad IW, Esch T and Michaelsen MM (2021) An Empirical Investigation of the Relationship Between Spirituality, Work Culture, and Burnout: The Need for an Extended Health and Disease Model. Front. Psychol. 12:723884. doi: 10.3389/fpsyg.2021.723884

 

Apart from biological, psychological, and social factors, recent studies indicate that spirituality and work culture also play an important role in the onset of burnout. Hence, the commonly applied bio-psycho-social model of health and disease might not be sufficient to comprehensively explain and describe burnout. This study empirically investigates the relationship between spirituality (operationalized by perceived meaningfulness of work) and work culture (operationalized by sense of homeliness of the working environment) with burnout risk and work engagement. For this purpose, an anonymous cross-sectional data collection with fully standardized questionnaires and selected socio-demographic and work-related items was conducted among working adults (n = 439) from different industries via social media and local health service centers. For all scales and subscales, we found significant moderate to strong correlations. Furthermore, positive meaning within the perceived meaningfulness of work scale was the largest beta coefficient for burnout (β = −0.65) and work engagement (β = 0.62). Within sense of homeliness, the largest beta coefficient for burnout was needs fulfillment (β = −0.34) and work engagement emotional connection (β = 0.36). The strong associations suggest that the current health and disease model needs to be expanded to a bio-psycho-socio-spirito-cultural model to be able to sufficiently describe burnout. The perceived meaningfulness of work and a sense of homeliness should be adequately considered when examining the onset of burnout, describing burnout as a concept, and explaining work engagement.

Improve Post-Traumatic Stress Disorder (PTSD) Symptoms with Loving Kindness Meditation

 

By John M. de Castro, Ph.D.

 

“You probably know that symptoms of posttraumatic stress disorder (PTSD) often include anxiety, unwanted memories, anger and avoidance. But did you know that meditation may be able to help? Meditative practices have been linked to decreases in hyperarousal, depression and insomnia.” – Jill Bormann

 

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.  Increasing self-compassion is important for improvement in PTSD symptoms. Mindfulness has been shown to increase self-compassion.  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. So, Loving Kindness Meditation may be an effective treatment for the symptoms of PTSD.

 

In today’s Research News article “Loving-Kindness Meditation vs Cognitive Processing Therapy for Posttraumatic Stress Disorder Among Veterans: A Randomized Clinical Trial.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8052593/ ) Kearney and colleagues recruited military veterans who were diagnosed with Post-Traumatic Stress Disorder (PTSD) and randomly assigned them to receive 2 weekly 90-minute group sessions of either Loving Kindness Meditation or Cognitive Processing Therapy (CPT). CPT “combines cognitive restructuring with emotional processing of trauma-related content”. They were measured before and after treatment and 3 and 6 months later for PTSD symptom severity and depression.

 

They found that in comparison to baseline both groups had significant but modest reductions in PTSD symptom severity and depression that were maintained 6 months after the end of treatment. The therapy groups did not differ in PTSD symptom severity but the group that practiced Loving Kindness Meditation had significantly lower level of depression after treatment and 6 months later.

 

These are interesting findings that suggest that both Loving Kindness Meditation and Cognitive Processing Therapy (CPT) produce modest relief of the symptoms of PTSD and depression in military veterans. But Loving Kindness Meditation produces better outcomes in relieving depression. Loving Kindness Meditation is known to improve mindfulness and compassion for the self and others, and this appears to help relieve the psychological consequences of trauma. This suggests that trauma, to some extent, produces a degree of self-blame which may be responsible for some of the symptoms. But these therapies produce only modest improvements suggesting that Loving Kindness Meditation is not a cure but may be useful as a component in the treatment of PTSD.

 

So, improve Post-Traumatic Stress Disorder (PTSD) symptoms with Loving Kindness Meditation.

 

“veteran participants self-reported a significant decrease in their PTSD symptoms and a high degree of satisfaction with the compassion meditation program.” – Laura McArdle

Study Summary

 

Kearney, D. J., Malte, C. A., Storms, M., & Simpson, T. L. (2021). Loving-Kindness Meditation vs Cognitive Processing Therapy for Posttraumatic Stress Disorder Among Veterans: A Randomized Clinical Trial. JAMA network open, 4(4), e216604. https://doi.org/10.1001/jamanetworkopen.2021.6604

 

Question

Is group loving-kindness meditation noninferior to group cognitive processing therapy for treatment of posttraumatic stress disorder (PTSD) among veterans?

Findings

In this randomized clinical trial, 184 veterans with PTSD were assigned to group loving-kindness meditation or group cognitive processing therapy; the differences in the decrease from baseline to 6-month follow-up for measures of PTSD and depression were very similar and within predefined margins considered not meaningfully different. Attendance was better for loving-kindness meditation.

Meaning

This study adds to the evidence indicating that interventions without a specific focus on trauma, including meditation-based interventions, can yield results similar to trauma-focused therapies.

Importance

Additional options are needed for treatment of posttraumatic stress disorder (PTSD) among veterans.

Objective

To determine whether group loving-kindness meditation is noninferior to group cognitive processing therapy for treatment of PTSD.

Design, Setting, and Participants

This randomized clinical noninferiority trial assessed PTSD and depression at baseline, posttreatment, and 3- and 6-month follow-up. Veterans were recruited from September 24, 2014, to February 5, 2018, from a large Veternas Affairs medical center in Seattle, Washington. A total of 184 veteran volunteers who met Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) criteria for PTSD were randomized. Data collection was completed November 28, 2018, and data analyses were conducted from December 10, 2018, to November 5, 2019.

Interventions

Each intervention comprised 12 weekly 90-minute group sessions. Loving-kindness meditation (n = 91) involves silent repetition of phrases intended to elicit feelings of kindness for oneself and others. Cognitive processing therapy (n = 93) combines cognitive restructuring with emotional processing of trauma-related content.

Main Outcomes and Measures

Co–primary outcomes were change in PTSD and depression scores over 6-month follow-up, assessed by the Clinician-Administered PTSD Scale (CAPS-5; range, 0-80; higher is worse) and Patient-Reported Outcome Measurement Information System (PROMIS; reported as standardized T-score with mean [SD] of 50 [10] points; higher is worse) depression measures. Noninferiority margins were 5 points on the CAPS-5 and 4 points on the PROMIS depression measure.

Results

Among the 184 veterans (mean [SD] age, 57.1 [13.1] years; 153 men [83.2%]; 107 White participants [58.2%]) included in the study, 91 (49.5%) were randomized to the loving-kindness group, and 93 (50.5%) were randomized to the cognitive processing group. The mean (SD) baseline CAPS-5 score was 35.5 (11.8) and mean (SD) PROMIS depression score was 60.9 (7.9). A total of 121 veterans (66%) completed 6-month follow-up. At 6 months posttreatment, mean CAPS-5 scores were 28.02 (95% CI, 24.72-31.32) for cognitive processing therapy and 25.92 (95% CI, 22.62-29.23) for loving-kindness meditation (difference, 2.09; 95% CI, −2.59 to 6.78), and mean PROMIS depression scores were 61.22 (95% CI, 59.21-63.23) for cognitive processing therapy and 58.88 (95% CI, 56.86-60.91) for loving-kindness meditation (difference, 2.34; 95% CI, −0.52 to 5.19). In superiority analyses, there were no significant between-group differences in CAPS-5 scores, whereas for PROMIS depression scores, greater reductions were found for loving-kindness meditation vs cognitive processing therapy (for patients attending ≥6 visits, ≥4-point improvement was noted in 24 [39.3%] veterans receiving loving-kindness meditation vs 9 (18.0%) receiving cognitive processing therapy; P = .03).

Conclusions and Relevance

Among veterans with PTSD, loving-kindness meditation resulted in reductions in PTSD symptoms that were noninferior to group cognitive processing therapy. For both interventions, the magnitude of improvement in PTSD symptoms was modest. Change over time in depressive symptoms was greater for loving-kindness meditation than for cognitive processing therapy.

Improve the Psychological Health of Obstetrics and Gynecology Patients during Covid-19 with a Mindfulness App

Improve the Psychological Health of Obstetrics and Gynecology Patients during Covid-19 with a Mindfulness App

 

By John M. de Castro, Ph.D.

 

“mindfulness meditation might be a viable low-cost intervention to mitigate the psychological impact of the COVID-19 crisis and future pandemics.” – Julie Lei Zhu

 

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. One of the primary effects of mindfulness that may be responsible for many of its benefits is that it improves the physiological and psychological responses to stress. The Covid-19 pandemic is extremely stressful particularly for patients who are pregnant or awaiting surgery. This training has been shown to improve the well-being of a wide variety of individuals. So, it should be helpful with these patients.

 

The vast majority of the mindfulness training techniques, however, require a trained teacher. The participants must be available to attend multiple sessions at scheduled times that may or may not be compatible with their schedules and at locations that may not be convenient. As an alternative, apps for smartphones have been developed. These have tremendous advantages in decreasing costs, making training schedules much more flexible, and eliminating the need to go repeatedly to specific locations. These should be particularly useful during the Covid-19 pandemic as attending in-person therapy sessions may not be safe or practicable. But the question arises as to the effectiveness of these apps in inducing mindfulness and reducing stress and improving psychological well-being in real-world medical patients.

 

In today’s Research News article “Mindfulness Effects in Obstetric and Gynecology Patients During the Coronavirus Disease 2019 (COVID-19) Pandemic: A Randomized Controlled Trial.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8132566/ ) Smith and colleagues recruited adult

obstetrics and gynecology patients who were either pregnant or awaiting gynecological surgery delayed due to the Covid-19 pandemic. They were randomly assigned to receive either standard care or to practice mindfulness for 10 minutes per day for 30 days with a commercially available smartphone app “Calm”. They were measured before training, at 14 days into training, and after training for perceived stress, anxiety, depression, and sleep disturbance.

 

They found that in comparison to baseline and the usual care control group, the group that practiced mindfulness with the “Calm” app had significantly lower levels of perceived stress, anxiety, depression, and sleep disturbance at 14 days and 30 days. The mindfulness group also reported lower levels of perceived stress due to Covid-19 and less worry about infections in their families. A high degree of satisfaction with the “Calm” app was reported.

 

Covid-19 has affected the psychological health of virtually everyone and past research has shown that mindfulness improves their psychological health. The present study demonstrates that this occurs in pregnant women and women awaiting gynecological surgery. An important aspect of the present study was the use of a smartphone app to do the mindfulness training. These apps are particularly useful during the Covid-19 pandemic as attending in-person therapy sessions may not be safe or practicable. This allows for mindfulness training with its benefits for the well-being of the patients to occur even in the midst of a pandemic.

 

So, improve the psychological health of obstetrics and gynecology patients during covid-19 with a mindfulness app.

 

“Mindfulness can help us acknowledge this situation, without allowing us to be carried away with strong emotions; it can, in turn, help bring ourselves back to a centered calm. Only then can we see more clearly what it is we have control over and what it is that we do not.“ – Michigan Medicine

Abstract

OBJECTIVE:

To assess the effect of a consumer-based mobile meditation application (app) on wellness in outpatient obstetric and gynecology patients during the coronavirus disease 2019 (COVID-19) pandemic.

METHODS:

We conducted a randomized controlled trial at a university outpatient clinic of obstetric and gynecology patients during the COVID-19 pandemic. Women were randomly assigned to the intervention group, who was prescribed a mobile meditation app for 30 days, or the control group, which received standard care. The primary outcome was self-reported perceived stress. Secondary outcomes included self-reported depression, anxiety, sleep disturbance, and satisfaction with the meditation app. A sample size of 80 participants (40 per group) was calculated to achieve 84% power to detect a 3-point difference in the primary outcome.

RESULTS:

From April to May 2020, 101 women were randomized in the study—50 in the meditation app group and 51 in the control group. Analysis was by intention-to-treat. Most characteristics were similar between groups. Perceived stress was significantly less in the intervention group at days 14 and 30 (mean difference 4.27, 95% CI 1.30–7.24, P=.005, d=0.69 and mean difference 4.28, 95% CI 1.68–6.88, P=.002, d=0.69, respectively). Self-reported depression and anxiety were significantly less in the intervention group at days 14 and 30 (depression: P=.002 and P=.04; anxiety: P=.01, and P=.04, respectively). Sleep disturbance was significantly less in the intervention group at days 14 and 30 (P=.001 and P=.02, respectively). More than 80% of those in the intervention group reported high satisfaction with the meditation app, and 93% reported that mindfulness meditation improved their stress.

CONCLUSION:

Outpatient obstetric and gynecology patients who used the prescribed consumer-based mobile meditation app during the COVID-19 pandemic had significant reductions in perceived stress, depression, anxiety, and sleep disturbance compared with standard care.

Meditation Alters the Brain in Conjunction with Alterations of Awareness

Meditation Alters the Brain in Conjunction with Alterations of Awareness

 

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 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, activity, and connectivity. Mindfulness practices in general are known to produce these kinds of changes in the structure and activity of the brain. In addition, meditation practice has been shown to result in attentiveness and serenity. There is little research, however, on how these changes in the brain produced by meditation are related to the changes in awareness in the practitioners.

 

In today’s Research News article “Meditation training modulates brain electric microstates and felt states of awareness.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8193519/) Zanesco and colleagues recruited healthy adults who had meditation experience and randomly assigned them to a wait-list control condition or to attend a 3-month Shambala residential meditation retreat with over 6 hours of meditation daily. They completed a daily experience questionnaire of positive and negative emotions and meditation experience. Before, in the middle and after the retreat the participants had their brain activity measured with electroencephalography (EEG).

 

They found that over the retreat there were continuous significant increases in attentiveness and serenity and the meditation qualities of physical relaxation, mental relaxation, attentional stability, and attentional vividness. In addition, the greater the increases in the meditation qualities the greater the increases in attentiveness and serenity. The analysis of the EEG data revealed that the retreat group had significant reductions in EEG Global Field Power and microstate durations and microstate occurrence frequency over the course of the retreat. Correlational analysis revealed that the greater the reductions over the retreat in the EEG Global Field Power and microstate durations the greater the increases in attentiveness and serenity.

 

These results document the increase in attentiveness and serenity and the quality of meditation that have been reported to occur over a meditation retreat. Significantly, they demonstrate that simultaneously there are changes in brain activity including a reduction in overall electrical activity and transient changes in electrical microstates in the brain over 40-120 microsecond intervals. Further the results demonstrate that reductions in these measures of brain electrical activity are correlated with improvements in attentiveness and serenity over the course of the retreat. This suggests that during a meditation retreat the brain becomes calmer and this is reflected in changes in subjective experience.

 

These results document that changes in the brain’s activities occur along with change in subjective experiences. The fact that they are correlated does no prove causation but is evidence in favor of causation. They suggest that during a meditation retreat there are changes produced in brain activity that produce greater attentiveness and serenity.

 

So, meditation alters the brain in conjunction with alterations of awareness.

Abstract

Meditation practice is believed to foster states of mindful awareness and mental quiescence in everyday life. If so, then the cultivation of these qualities with training ought to leave its imprint on the activity of intrinsic functional brain networks. In an intensive longitudinal study, we investigated associations between meditation practitioners’ experiences of felt mindful awareness and changes in the spontaneous electrophysiological dynamics of functional brain networks. Experienced meditators were randomly assigned to complete 3 months of full‐time training in focused‐attention meditation (during an initial intervention) or to serve as waiting‐list controls and receive training second (during a later intervention). We collected broadband electroencephalogram (EEG) during rest at the beginning, middle, and end of the two training periods. Using a data‐driven approach, we segmented the EEG into a time series of transient microstate intervals based on clustering of topographic voltage patterns. Participants also provided daily reports of felt mindful awareness and mental quiescence, and reported daily on four experiential qualities of their meditation practice during training. We found that meditation training led to increases in mindful qualities of awareness, which corroborate contemplative accounts of deepening mental calm and attentional focus. We also observed reductions in the strength and duration of EEG microstates across both interventions. Importantly, changes in the dynamic sequencing of microstates were associated with daily increases in felt attentiveness and serenity during training. Our results connect shifts in subjective qualities of meditative experience with the large‐scale dynamics of whole brain functional EEG networks at rest.
