Improve Sleep and Reduce Insomnia with Mindfulness

Improve Sleep and Reduce Insomnia with Mindfulness

 

By John M. de Castro, Ph.D.

 

Given the absence of side effects and the positive potential benefits of mindfulness that extend beyond sleep, we encourage people with chronic insomnia, particularly those unable or unwilling to use sleep medications, to consider mindfulness training.” – Cynthia Gross

 

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 disorder, and 10% have chronic insomnia

 

Insomnia is more than just an irritant. Sleep deprivation is associated with decreased alertness and a consequent reduction in performance of even simple tasks, decreased quality of life, increased difficulties with memory and problem solving, increased likelihood of accidental injury including automobile accidents, and increased risk of dementia and Alzheimer’s disease. It also can lead to anxiety about sleep itself. This is stressful and can produce even more anxiety about being able to sleep. About 4% of Americans revert to sleeping pills. But these do not always produce high quality sleep and can have problematic side effects. So, there is a need to find better methods to treat insomnia. Mindfulness-based practices have been reported to improve sleep amount and quality and help with insomnia.

 

In today’s Research News article “The Effect of Mind-Body Therapies on Insomnia: A Systematic Review and Meta-Analysis.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6393899/ ), Wang and colleagues review, summarize and perform a meta-analysis of the effects of mind-body practices on sleep. They uncovered 49 studies employing meditation, tai chi, qigong, and yoga practices and measuring sleep.

 

They report that the published studies found that meditation, tai chi, qigong, and yoga practices significantly reduced insomnia and improved the quality of sleep particularly when compared to no-treatment control groups. They also report that the benefits of the mind-body practices were greater in healthy individuals than in clinical populations. These significant effects were obtained by subjective reports, while objective sleep diary and actigraph measures were not significant.

 

These are interesting results that suggest that mind-body practices significantly improve the participants evaluations of the quality of sleep and insomnia. This is important as individuals in modern society tend not to get sufficient sleep and adequate sleep is important to the psychological and physical well-being of the individual and their performance during the day. Engaging in these mind-body practices of meditation, tai chi, qigong, and yoga practice have been shown to have many other benefits in addition to the improvement of sleep.

 

So, improve sleep and reduce insomnia with mindfulness.

Abstract

Background/Purpose

Sleep plays an important role in individuals’ health. The functions of the brain, the cardiovascular system, the immune system, and the metabolic system are closely associated with sleep. As a prevalent sleep disorder, insomnia has been closely concerned, and it is necessary to find effective therapies. In recent years, a growing body of studies has shown that mind-body therapies (MBTs) can improve sleep quality and ameliorate insomnia severity. However, a comprehensive and overall systematic review has not been conducted. In order to examine the effect of MBTs on insomnia, we conducted a systematic review and meta-analysis evaluating the effects of MBTs on sleep quality in healthy adults and clinical populations.

Methods

PubMed, EMBASE, the Cochrane Library, and review of references were searched up to July 2018. English language studies of all designs evaluating the effect of MBTs on sleep outcomes in adults with or without diseases were examined. To calculate the SMDs and 95% CIs, we used a fixed effect model when heterogeneity was negligible and a random effect model when heterogeneity was significant.

Results

49 studies covering 4506 participants published between 2004 and 2018 were identified. Interventions included meditation, tai chi, qigong, and yoga which lasted 4 to 24 weeks. The MBTs resulted in statistically significant improvement in sleep quality and reduction on insomnia severity but no significant effects on sleep quantity indices, which were measured by sleep diary or objective measures. We analyzed the effects of tai chi and qigong separately as two different MBTs for the first time and found that qigong had a slight advantage over tai chi in the improvement of sleep quality. Subgroup analyses revealed that the effect of MBTs on sleep quality in healthy individuals was larger than clinical populations. The effect of MBTs might be influenced by the intervention duration but not the frequency.

Conclusions

MBTs can be effective in treating insomnia and improving sleep quality for healthy individuals and clinical patients. More high-quality and well-controlled RCTs are needed to make a better conclusion in further study.

Reduce Worry and Rumination and Improve Emotion Regulation Lowering Anxiety and Depression with Mindfulness

Reduce Worry and Rumination and Improve Emotion Regulation Lowering Anxiety and Depression with Mindfulness

 

By John M. de Castro, Ph.D.

 

“The practice of mindfulness teaches us a different way to relate to our thoughts, feelings, and emotions as they arise. It is about learning to approach and acknowledge whatever is happening in the present moment, setting aside our lenses of judgment and just being with whatever is there, rather than avoiding it or needing to fix it.” – Elisha Goldstein

 

Mindfulness training has been shown through extensive research to be effective in improving the physical and psychological condition of otherwise healthy people and also treating the physical and psychological issues of people with illnesses. This has led to an increasing adoption of mindfulness techniques for the health and well-being of both healthy and ill individuals.

 

Worry (concern about the future) and rumination (repetitive thinking about the past) are associated with mental illness, particularly anxiety and depression. Fortunately, worry and rumination may be interrupted by mindfulness and emotion regulation improved by mindfulness. These may be some of the mechanisms by which mindfulness training improves anxiety and depression. In today’s Research News article “Mindfulness and Symptoms of Depression and Anxiety in the General Population: The Mediating Roles of Worry, Rumination, Reappraisal and Suppression.” (See summary below or view the full text of the study at: https://www.frontiersin.org/articles/10.3389/fpsyg.2019.00506/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_934868_69_Psycho_20190314_arts_A ), Parmentier and colleagues examine the ability of mindfulness to improve emotion regulation and reduce worry and rumination and thereby improve anxiety and depression.

 

They recruited adult participants online and had them complete an online survey measuring mindfulness, anxiety, depression, rumination, worry, emotion regulation, and meditation history. They found that meditation practice was not associated with anxiety or depression directly but rather through its positive association with mindfulness which was strongly negatively associated with anxiety and depression. Mindfulness was associated with lower levels of anxiety and depression directly and also indirectly through its association with rumination and worry and the emotion regulation mechanisms of suppression and reappraisal. Mindfulness was associated with lower levels of suppression, rumination, and worry and higher levels of reappraisal. which in turn were associated with anxiety and depression.

 

These findings suggest that meditation practice increases mindfulness and this decreases anxiety and depression. It does so directly and indirectly. Mindfulness reduces the tendency to suppress, prevent, anxiety and depression from arising which allows for full mindful appreciation of these emotions and as a result produces an actual reduction in them. It also decreases worry and rumination that normally heighten anxiety and depression. At the same time mindfulness increases reappraisal, heightening the ability to investigate the causes of anxiety and depression, resulting in their reduction. Worry and rumination were the most powerful mediating factors while suppression and reappraisal were still significant factors but substantially weaker.

 

These results support the conclusion that mindfulness directly decreases anxiety and depression. But mindfulness also acts indirectly by affecting has a number of psychological processes including improving emotion regulation and by decreasing the counterproductive cognitive processes of worry and rumination.

 

So, reduce worry and rumination and improve emotion regulation lowering anxiety and depression with mindfulness.

 

“With mindfulness practice, we can learn how to unhook from rumination and cut ourselves (and others) the slack requisite for increasing clarity and ease of being.” – Mitch Abblett

Study Summary

 

Parmentier FBR, García-Toro M, García-Campayo J, Yañez AM, Andrés P and Gili M (2019) Mindfulness and Symptoms of Depression and Anxiety in the General Population: The Mediating Roles of Worry, Rumination, Reappraisal and Suppression. Front. Psychol. 10:506. doi: 10.3389/fpsyg.2019.00506

 

The present study examined the effects of mindfulness on depression and anxiety, both direct and indirect through the mediation of four mechanisms of emotional regulation: worry, rumination, reappraisal and suppression. Path analysis was applied to data collected from an international and non-clinical sample of 1151 adults, including both meditators and non-meditators, who completed an online questionnaire battery. Our results show that mindfulness are related to lower levels of depression and anxiety both directly and indirectly. Suppression, reappraisal, worry and rumination all acted as significant mediators of the relationship between mindfulness and depression. A similar picture emerged for the relationship between mindfulness and anxiety, with the difference that suppression was not a mediator. Our data also revealed that the estimated number of hours of mindfulness meditation practice did not affect depression or anxiety directly but did reduce these indirectly by increasing mindfulness. Worry and rumination proved to be the most potent mediating variables. Altogether, our results confirm that emotional regulation plays a significant mediating role between mindfulness and symptoms of depression and anxiety in the general population and suggest that meditation focusing on reducing worry and rumination may be especially useful in reducing the risk of developing clinical depression.

Enhance Flow in Athletes with Mindfulness

Enhance Flow in Athletes with Mindfulness

 

By John M. de Castro, Ph.D.

 

mindfulness-based interventions for sports are effective because they help athletes direct their attention to the current athletic task, while minimizing external distractions.” – Mitch Plemmons

 

Athletic performance requires the harmony of mind and body. Excellence is in part physical and in part psychological. That is why an entire profession of Sports Psychology has developed. “In sport psychology, competitive athletes are taught psychological strategies to better cope with a number of demanding challenges related to psychological functioning.” They use a number of techniques to enhance performance including mindfulness training. It has been shown to improve attention and concentration and emotion regulation and reduces anxiety and worry and rumination, and the physiological and psychological responses to stress. As a result, mindfulness training has been employed by athletes and even by entire teams to enhance their performance.

 

Flow refers to a state of mind that is characterized by a complete absorption with the task at hand, often resulting in enhanced skilled performance. The flow state underlies the athletes’ feelings and thoughts when they recall the best performances of their careers. It is obvious that the notion of flow and mindfulness have great similarity. There is little known, however, about the relationship between mindfulness and flow in athletes.

 

In today’s Research News article “Mindfulness training enhances flow state and mental health among baseball players in Taiwan.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6307497/ ), Chen and colleagues recruited the members of an elite male baseball team in Taiwan and provided them with a 4-session mindfulness training including meditation, yoga, and discussion of the application of mindfulness to their sport. They were measured before and after training and 4 weeks later for depression, anxiety, eating disorders, sleep quality, competitive anxiety, mindfulness, and flow state.

 

They found that after training and at follow-up there was a significant increase in sleep quality and flow state and a significant decrease in eating disorders and competitive anxiety. In addition, the higher the level of mindfulness of the player, the greater the level of flow state. They also saw a non-significant increase in the team’s performance after the training.

 

These are interesting results but conclusions need to be tempered with the fact that there wasn’t a control condition. This leaves many alternative confounding interpretations. Nevertheless, these pilot findings suggest that further research is warranted to investigate the effect of mindfulness training on athletic flow state. These results contribute to the growing body of research that suggests that being mindful produces enhanced athletic performance.

 

So, enhance flow in athletes with mindfulness.

 

“Achieving peak performance and especially being able to develop flow experiences in athletes is the holy grail of sport psychology.  . . researches are getting one step closer to unveiling the psychological factors that influence flow experiences, and mindfulness could be an essential part of the puzzle.” – Carmilo Saenz

Abstract

Objective

To examine the effect of mindfulness-based training on performance and mental health among a group of elite athletes.

Methods

This study aimed to evaluate the effect of mindful sport performance enhancement (MSPE) on mental health, flow state, and competitive state anxiety using a 4-week workshop. We recruited an amateur baseball team (N=21) in Taiwan, and collected information by self-reported questionnaires administered before, immediately after, and at a 4-week follow-up. The primary outcome was to evaluate sports performance by flow state and competitive state anxiety, which included self-confidence, somatic anxiety, and cognitive anxiety. The secondary outcome was to explore whether MSPE intervention can improve anxiety, depression, sleep disturbance, and eating disorders.

Result

After the workshop and follow-up 1 month later, we found improvements in flow state (P=0.001; P=0.045), cognitive anxiety in competitive anxiety (P=0.056; P=0.008), global eating disorder (P=0.009; P<0.001), marked shape concern (P=0.005; P<0.001), and weight concern (P=0.007; P<0.001). Scores of sleep disturbance (P=0.047) showed significant improvement at follow-up. We also found significant association between flow state and mindfulness ability (P<0.001).

Conclusion

This is the first mindfulness intervention to enhance athletes’ performance in Taiwan, and also the first application of MSPE for team sports. Our study results suggested that mindfulness ability is associated with flow state, and that MSPE is a promising training program for strengthening flow state and mental health.

Decrease Hypertension with Yoga Practice

Decrease Hypertension with Yoga Practice

 

By John M. de Castro, Ph.D.

 

“Yoga, when performed mindfully, can reduce this type of stress-induced hypertension, while addressing its underlying causes. It pacifies the sympathetic nervous system and slows down the heart, while teaching the muscles and mind to relax deeply.” – Marla Apt

 

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.

 

High blood pressure, because it doesn’t have any primary symptoms, is usually only diagnosed by direct measurement of blood pressure usually by a health care professional. When hypertension is chronically present over three quarters of patients are treated with 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 alternative to drug treatments for hypertension. Mindfulness practices have been shown to aid in controlling hypertension. Exercise is also known to help. So, yoga practice, which combines mindfulness practice with exercise would seem to be a good candidate practice for the treatment of hypertension. Indeed, yoga practice appears to lower blood pressure in hypertension. But yoga practices can contain a number of components including meditation, breathing exercises, postures, chanting, and mantras. It is not known, whether the postures included in the practice are necessary for the beneficial effects of yoga practice on hypertension.

 

In today’s Research News article “Yoga in Arterial Hypertension.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6375068/ ), Cramer and colleagues recruited adult patients with primary arterial hypertension receiving antihypertensive medication. They were randomly assigned to receive either yoga training that either included postures or without postures, or a wait-list control condition. The yoga practice consisted of 90 minutes, once a week, for 12 weeks of meditation, relaxation techniques, and postures for the yoga with postures group. The participants were encouraged and provided materials to practice daily at home. They were measured before and after training and 26 weeks later for systolic and diastolic blood pressure.

 

They found that at the end of training the yoga group without postures had a greater reduction in systolic blood pressure than either the control group or the group with yoga postures. But, at follow-up, 26 weeks later, the yoga group that included postures had a greater reduction in systolic blood pressure than either the control group or the group without yoga postures. Diastolic blood pressure was not affected. It should be noted that these benefits were obtained in patients taking antihypertensive medications. So, the yoga practice benefits supplemented those of the drugs.

 

These are interesting results that suggest that on the short-term yoga practice without postures is best for blood pressure reduction in patients with hypertension while for the long-term yoga with postures is best. The relaxation produced by practicing meditation and relaxation may have the immediate consequence of decreasing blood pressure but doesn’t appear to be sustained while the exercise involved in postures, like occurs with other aerobic exercises, may have more long-term benefits for the cardiovascular system.

 

These benefits are important as reducing blood pressure in patients with hypertension is important for their health, longevity, and well-being. Yoga appears to be a safe, effective, and relatively inexpensive treatment. In addition, yoga practice has psychological and social benefits that can help to maintain practice over the long-term.

 

So, decrease hypertension with yoga practice.

 

“Yoga, along with deep breathing exercises, meditation and inner reflection, is a good adjunctive and integrative cardiovascular approach to better health, including lowering blood pressure, as this data suggests,” – David Friedman

Abstract

Background

Yoga seems to exert its effect against arterial hypertension mainly through the associated breathing and meditation techniques, and less so through yoga postures. The goal of this trial was to compare the blood pressure–lowering effect of yoga interventions with and without yoga postures in patients with arterial hypertension.

Methods

75 patients taking medications for arterial hypertension (72% women, mean age 58.7 ± 9.5 years) were randomized into three groups: a yoga intervention group with yoga postures (25 patients, of whom 5 dropped out of the trial before its end), a yoga intervention group without yoga postures (25 patients, 3 dropouts), and a wait list control group (25 patients, one dropout). The interventions consisted of 90 minutes of yoga practice per week for twelve weeks. The data collectors, who were blinded to the intervention received, assessed the primary outcome measures “systolic 24-hour blood pressure” and “diastolic 24-hour blood pressure” before and after the intervention. In this report, we also present the findings on secondary outcome measures, including follow-up data.

Results

After the intervention, the systolic 24-hour blood pressure in the yoga intervention group without yoga postures was significantly lower than in the control group (group difference [?]= -3.8 mmHg; [95% confidence interval (CI): (-0.3; -7.4) p = 0.035]); it was also significantly lower than in the yoga intervention group with yoga postures (? = -3.2 mmHg; 95% CI: [-6.3; -0.8]; p = 0.045). Diastolic blood pressures did not differ significantly across groups. No serious adverse events were encountered in the course of the trial.

Conclusion

In accordance with the findings of earlier studies, we found that only yoga without yoga postures induced a short-term lowering of ambulatory systolic blood pressure. Yoga is safe and effective in patients taking medications for arterial hypertension and thus can be recommended as an additional treatment option for persons in this category.

Improve Sleep in Breast Cancer Patients Undergoing Chemotherapy with Yoga

Improve Sleep in Breast Cancer Patients Undergoing Chemotherapy with Yoga

 

By John M. de Castro, Ph.D.

 

“Sleep disturbance is a common problem for women with breast cancer, and can have a variety of causes, from stress and depression related to the treatment or diagnosis, to a side effect of some of the drugs and anti-nausea medications used in chemotherapy regimens. Yoga not only produced benefits in the short term, it also produced benefits in sleep quality three months and six months after treatment.” – Paul Raeburn

 

Receiving a diagnosis of cancer has a huge impact on most people. Feelings of depression, anxiety, and fear are very common and are normal responses to this life-changing and potentially life-ending experience. But cancer diagnosis is not necessarily a death sentence. Over half of the people diagnosed with cancer are still alive 10 years later and this number is rapidly increasing. But, surviving cancer carries with it a number of problems. Fatigue and insomnia are common symptoms in the aftermath of surviving breast cancer.

 

Mindfulness training has been shown to help with cancer recovery and help to alleviate many of the residual physical and psychological symptoms, including fatiguestress,  sleep disturbance, and anxiety and depression. Yoga practice is a form of mindfulness training that has been shown to be beneficial for cancer patients.  In today’s Research News article “Randomized trial of Tibetan yoga in patients with breast cancer undergoing chemotherapy.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5735004/ ), Chaoul and colleagues examine the ability of yoga practice to improve sleep in breast cancer patients.

 

They recruited patients with Stage 1 to 3 breast cancer scheduled to undergo chemotherapy. They were randomly assigned to usual care or to either receive a Tibetan Yoga Program or a stretching program. Participants met for 4, 75 to 90-minute, sessions during chemotherapy and 3 booster sessions over the next 6 months. The participants were also encouraged to practice at home. The Tibetan Yoga Program consisted of “1) mindfulness and focused attention through guided meditation with breathing and visualization; 2) an alternate nostril breathing practice and a breath retention exercise; 3) Tsa Lung movements; and 4) closing with a brief compassion-based meditation.” The participants were measured before and after the programs and 3, 6, and 12 months later for sleep quality, fatigue, and actigraph measured sleep patterns.

 

They found that all groups improved in sleep quality and fatigue over the 12-month measurement period. But the Tibetan Yoga group had significantly less daily sleep disturbances and fewer minutes awake before sleep onset. Hence, participation in the Tibetan Yoga Program had modest benefits for the quality of sleep for the patients. The Tibetan Yoga Program contains a number of different components including meditation, postures, and breathing exercises. It is impossible to determine in the current study which components or which combinations of components were necessary and sufficient for the benefits.

 

These results are encouraging but not clinically significant as the effects were very modest. But,

it should be kept in mind that yoga and meditation programs have been shown to improve a number of other impacts of breast cancer diagnosis and survival. So, the total impact of participation in yoga for breast cancer patients may be much greater than implied by the current results.

 

So, improve sleep in breast cancer patients undergoing chemotherapy with yoga.

 

“it is encouraging to see that the women who practiced yoga outside of class had improved sleep outcomes over time. Previous research has established that yoga effectively reduces sleep disturbances for cancer patients, but have not included active control groups or long-term follow-up.” – Lorenzo Cohen

A., Li, Y., … Cohen, L. (2017). Randomized trial of Tibetan yoga in patients with breast cancer undergoing chemotherapy. Cancer, 124(1), 36-45.

 

Abstract

BACKGROUND

This randomized trial examined the effects of a Tibetan yoga program (TYP) versus a stretching program (STP) and usual care (UC) on sleep and fatigue in women with breast cancer undergoing chemotherapy.

METHODS

Women with stage I–III breast cancer undergoing chemotherapy were randomized to TYP (n=74), STP (n=68), or UC (n=85) groups. Participants in the TYP and STP groups participated in 4 sessions during chemotherapy, followed by three booster sessions over the subsequent 6 months, and encouraged to practice at home. Self-report measures of sleep disturbances (Pittsburgh Sleep Quality Index) fatigue (Brief Fatigue Inventory), and actigraphy were collected at baseline, 1-week post-treatment, and 3, 6 and 12 months.

RESULTS

There were no group differences in total sleep disturbances or fatigue levels over time. However, patients in TYP reported fewer daily disturbances 1-week post-treatment than STP (difference=−0.43, 95% CI: −0.82, −0.04, P=0.03) and UC (difference=−0.41, 95.5% CI: −0.77, −0.05, P=0.02). Group differences at the other time points were maintained for TYP versus STP. Actigraphy data revealed greater minutes awake after sleep onset for STP 1-week post treatment versus TYP (difference=15.36, 95% CI: 7.25,23.48, P=0.0003) and UC (difference=14.48, 95% CI: 7.09,21.87, P=0.0002). Patients in TYP who practiced at least two times a week during follow-up reported better PSQI and actigraphy outcomes at 3 and 6 months post-treatment than those who did not and better than those in UC.

CONCLUSIONS

Participating in TYP during chemotherapy resulted in modest short-term benefits in sleep quality, with long-term benefits emerging over time for those who practiced TYP at least two times a week.

Change the Brain for Greater Well-Being with Meditation

Change the Brain for Greater Well-Being with Meditation

 

By John M. de Castro, Ph.D.

 

Meditation provides experiences that the mind can achieve no other way, such as inner silence and expanded awareness. And as the mind gains experience, the brain shows physical activity as well—sometimes profound changes.” – Depak Chopra

 

There has accumulated a large amount of research demonstrating that mindfulness has significant benefits for psychological, physical, and spiritual wellbeing. One way that mindfulness practices may produce these benefits is by altering the brain. 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 “Short‐term Sahaja Yoga meditation training modulates brain structure and spontaneous activity in the executive control network.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6346416/pdf/BRB3-9-e01159.pdf ), Dodich and colleagues recruited meditation naïve college students and randomly assigned them to either a wait-list control condition or to receive 1-hour Sahaja yoga meditation practice 4 times per week for 4 weeks. Sahaja yoga meditation is an open monitoring meditation technique designed to produce mental silence. The participants underwent brain scans with functional Magnetic Resonance Imaging (fMRI) before and after the 4 weeks of meditation training.

 

They found that in comparison to baseline and the wait-list controls, the participants who received meditation training and practice had significant increases in the brain grey matter density in the inferior frontal gyrus. They also found that the greater the grey matter density the greater the self-reported well-being by the meditation participants.

 

The inferior frontal gyrus is known to be involved in attention, self-control, and self-awareness. These are exactly the skills trained in meditation practice. This suggests that this relatively short-term practice produces neuroplastic changes in the brain expanding the brain matter in the regions underlying the trained skills and this is associated with improved well-being.

 

So, change the brain for greater well-being with meditation.

 

“So, what’s the best way to build a better brain? Backed by 1000’s of studies, meditation is the neuroscientific community’s most proven way to upgrade the human brain.” – EOC Institute

Abstract Introduction: While cross‐sectional studies have shown neural changes in long‐term meditators, they might be confounded by self‐selection and potential baseline differences between meditators and non meditators. Prospective longitudinal studies of the effects of meditation in naïve subjects are more conclusive with respect to causal inferences, but related evidence is so far limited. Methods: Here, we assessed the effects of a 4‐week Sahaja Yoga meditation training on gray matter density and spontaneous resting‐state brain activity in a group of 12 meditation‐naïve healthy adults. Results: Compared with 30 control subjects, the participants to meditation training showed increased gray matter density and changes in the coherence of intrinsic brain activity in two adjacent regions of the right inferior frontal gyrus encompassing the anterior component of the executive control network. Both these measures correlated with self‐reported well‐being scores in the meditation group. Conclusions: The significant impact of a brief meditation training on brain regions associated with attention, self‐control, and self‐awareness may reflect the engagement of cognitive control skills in searching for a state of mental silence, a distinctive feature of Sahaja Yoga meditation. The manifold implications of these findings involve both managerial and rehabilitative settings concerned with well‐being and emotional state in normal and pathological conditions.

Improve Mental Health in Older Adults with Online Meditation Practice

Improve Mental Health in Older Adults with Online Meditation Practice

 

By John M. de Castro, Ph.D.

 

The good news is that there are steps we can take right now to make the goal of “aging gracefully” more attainable. Mindfulness training is one of those steps; research has clearly shown that regular meditation comes with a wide range of physical, mental and emotional health benefits should particularly interest seniors.” – Mindworks

 

Human life is one of constant change. We revel in our increases in physical and mental capacities during development but regret their decline during aging. As we age, there are systematic progressive declines in every system in the body, the brain included. This includes our mental abilities and results in impairments in memory, attention, and problem-solving ability. It is inevitable and cannot be avoided. Aging also results in changes in mental health. Depression is very common in the elderly. The elderly cope with increasing loss of friends and family, deteriorating health, as well as concerns regarding finances on fixed incomes. All of these are legitimate sources of worry. In addition, many elderly experience withdrawal and isolation from social interactions. But, no matter how reasonable, the increased loneliness, worry and anxiety add extra stress that can impact on the elderly’s already deteriorating physical and psychological health.

 

Mindfulness appears to be effective for an array of physical and psychological issues that occur with aging. It appears to strengthen the immune system and reduce inflammation. It has also been shown to be beneficial in slowing or delaying physical and mental decline with aging. and improve cognitive processes. It has also been shown to reduce anxietyworry, and depression and improve overall mental health. Since the global population of the elderly is increasing at unprecedented rates, it is imperative to investigate safe and effective methods to improve mental health in the elderly. In addition, the elderly frequently have mobility issues and going to a treatment facility may be challenging. A promising alternative is online mindfulness programs. It is not known, however, whether these will be acceptable and effective in elderly populations.

 

In today’s Research News article “Internet Mindfulness Meditation Intervention (IMMI) Improves Depression Symptoms in Older Adults.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6313401/pdf/medicines-05-00119.pdf ), Wahbeh and colleagues recruited older adults aged 55 to 80 years who were not currently meditators and demonstrated symptoms of depression. They were randomly assigned either to a wait list control group or to receive 6 weeks of online 1-hour once a week meditation training with 20 minutes daily guided meditations to be practiced at their convenience. Meditation included both body scan and sitting meditations. The participants were measured before and after training and 7 weeks later for mindfulness depression, resilience, spiritual experiences, insomnia, pain, perceived stress, and satisfaction with the intervention.

 

They found that in comparison to the baseline and the wait list control participants after meditation practice there were significant reductions in depression, insomnia, perceived stress, and pain interference, and significant increases in spirituality. These effects were maintained at follow-up 7 weeks after the end of treatment.

 

These are important findings. The vast majority of the mindfulness training techniques require a certified trained therapist. This results in costs that many clients can’t afford. In addition, the participants must be available to attend multiple sessions at particular scheduled times that may or may not be compatible with their schedules and at locations that may not be convenient. The online mindfulness training program has tremendous advantages in decreasing costs, making training schedules much more flexible, and eliminating the need to go repeatedly to specific locations. These advantages are particularly important for elderly individuals. In addition, there is evidence that mindfulness programs delivered online can be quite effective.

 

The current findings demonstrate that online meditation training can be successfully implemented with older adults with symptoms of depression and that this program can produce significant improvements in the mental health of the participants. This suggests that such programs can be widely and inexpensively distributed over the internet to improve the well-being of the elderly.

 

So, improve mental health in older adults with online meditation practice.

Study Summary

 

Helané Wahbeh. Internet Mindfulness Meditation Intervention (IMMI) Improves Depression Symptoms in Older Adults. Medicines (Basel) 2018 Dec; 5(4): 119. Published online 2018 Nov 2. doi: 10.3390/medicines5040119

 

Abstract: Background: Older adults have fewer physiological reserves and are more likely to be affected by stress. Mindfulness meditation has the potential to be an effective treatment for depression, but little research has been conducted on older adults. The primary objective of this study was to evaluate depression symptom changes in older adults (55–80 years old) taking an Internet Mindfulness Meditation Intervention (IMMI) compared to a waitlist control. The secondary aims were to collect data on pain, perceived stress, resilience, mindfulness, sleep quality, and spirituality. Methods: Fifty older adults were randomized to either the Internet Mindfulness Meditation Intervention, a six-week online intervention with daily home practice, or a waitlist control. Measures were collected at baseline, after the six-week intervention period, and again six weeks later after the waitlist participants completed IMMI. Adherence to home practice was objectively measured with iMINDr. Changes in outcomes for the IMMI and waitlist participants were compared. All participants who completed IMMI were then combined for a within-participant analysis. Results: Adherence to the intervention was low, likely due to a traumatic event in the local area of the participants. Compared to the waitlist participants, those in IMMI had improved depression symptoms (p < 0.00005), perceived stress (p = 0.0007), insomnia symptoms (p = 0.0009), and pain severity (p = 0.05). In the within-participant analysis of all data before and after IMMI (i.e., those initially randomized to IMMI and waitlist participants who took it), we found improvements in depression symptoms (p = 0.0001), perceived stress (p = 0.0001), insomnia symptoms (p < 0.00005), pain interference (p = 0.003), and spirituality (p = 0.018). A seven-week follow-up after the original six-week IMMI program showed sustained improvements in the IMMI participants. Conclusions: IMMI improved depression and related symptoms compared to controls despite minimal support from study staff. IMMI offers a low-dose, low-cost, easily accessible mindfulness meditation intervention for older adults with depression symptoms.

Improve Creativity with Cyclic Meditation

Improve Creativity with Cyclic Meditation

 

By John M. de Castro, Ph.D.

 

Stillness is where creativity and solutions to problems are found.” – Eckhart Tolle

Problem solving most frequently involves logic and reasoning, sometimes along with mathematics. In this case focused attention is the key. The mind wandering off topic interferes with the concentration required for obtaining the solution. But when a solution does not occur and the individual fails to solve the problem a completely different process transpires producing insight. If logic and reason fail, then fanciful and out-of-the box thinking may be needed. In this case mind wandering, taking the thought process away from the failed logical strategy, is superior, often producing a solution in a flash, an “aha” moment. In this case focused attention prevents the individual from seeing an unusual or creative solution. While the mind wandering off topic increases the discursive thinking that is required for obtaining the insightful solution.

 

Perhaps the best method to improve creativity and problem solving is to practice both activating and relaxing mindfulness practices. This occurs in cyclic meditation which involves yoga poses (Activation) and meditative relaxation (calming). It is not known whether cyclic meditation can enhance creative thinking and if so, how it might be affecting brain activity.

 

In today’s Research News article “Association between Cyclic Meditation and Creative Cognition: Optimizing Connectivity between the Frontal and Parietal Lobes.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6329224/ ), Shetkar and colleagues recruited college students and randomly assigned them to receive 7 daily 35 minute sessions of either cyclic meditation or supine rest (Shavasana). Participants were measured before and after treatment for creative (divergent) thinking. During rest, creativity testing and cyclic meditation the participants had their brain activity measured with an electroencephalograph (EEG).

 

They found that after training in comparison to control participants there was a significant increase (18%) in creativity in the cyclic meditation group including large increases in fluency, originality, elaboration, and flexibility. They also found that brain activity in the gamma frequency bands (high frequency, 25 to 100 cycles per second) of the EEG increased in the frontal and parietal lobes after cyclic meditation practice with indications of increased connectivity between these lobes. The frontal lobes have long been associated with higher level thinking including creative thought.

 

These are very interesting results. Cyclic meditation is different from relaxation in its use of yoga postures and guided meditation. It remains for future research to determine which of these components or both are necessary and sufficient for producing the improvements in creativity. The findings suggest that engaging in cyclic meditation enhances activity in the areas of the brain that are responsible for higher level cognitive functions and as a result enhances creative thinking. It also remains for future research to determine if these effects are lasting or are only present in the immediate aftermath of training.

 

So, improve creativity with cyclic meditation.

 

A state of conscious awareness resulting from living in the moment is not sufficient for creativity to come about. To be creative, you need to have, or be trained in, the ability to observe, notice, and attend to phenomena that pass your mind’s eye.” – Matthijs Baas

Study Summary

 

Shetkar, R. M., Hankey, A., Nagendra, H. R., & Pradhan, B. (2019). Association between Cyclic Meditation and Creative Cognition: Optimizing Connectivity between the Frontal and Parietal Lobes. International journal of yoga, 12(1), 29-36.

 

Abstract

Background:

Important stages of creativity include preparation, incubation, illumination, and verification. Earlier studies have reported that some techniques of meditation promote creativity but have not specified which stage is enhanced. Here, we report the influence of cyclic meditation (CM) on creative cognition measured by a divergent thinking task. Our aim was to determine the degree of association between the two.

Methods:

Twenty-four university students were randomly assigned to an experimental group (CM) and controls (Supine Rest), 35 min/day for 7 days. Creativity performance was assessed pre and post using Abbreviated Torrance Test for Adults (ATTA), while 64-channel electroencephalography (EEG) was used to measure brain activity during both CM/SH and the creativity test.

Results:

Results indicated that CM training improved creativity performance, producing a shift to predominant gamma activity during creativity compared controls who showed delta activity. Furthermore, the experimental group showed more activation of frontal and parietal regions (EEG leads F3, F4 and P3, P4) than controls, i.e., the regions of the executive network responsible for creative cognition, our particular regions of interest where specialized knowledge is being stored.

Conclusion:

Improvement on creativity test performance indicates that CM increases association and strengthens the connectivity between frontal and parietal lobes, the major nodes of default mode network and executive attention network, enhancing the important stages of creativity such as preparation, incubation, and illumination.

Improve Brain Connectivity with Meditation

Improve Brain Connectivity with Meditation

 

By John M. de Castro, Ph.D.

 

“The meditation-and-the-brain research has been rolling in steadily for a number of years now, with new studies coming out just about every week to illustrate some new benefit of meditation. Or, rather, some ancient benefit that is just now being confirmed with fMRI or EEG. The practice appears to have an amazing variety of neurological benefits – from changes in grey matter volume to reduced activity in the “me” centers of the brain to enhanced connectivity between brain regions.“ – Alice Walton

 

There has accumulated a large amount of research demonstrating that mindfulness has significant benefits for psychological, physical, and spiritual wellbeing. It even improves high level thinking known as executive function and emotion regulation and compassion. Its positive effects are so widespread that it is difficult to find any other treatment of any kind with such broad beneficial effects on everything from thinking to mood and happiness to severe mental and physical illnesses. This raises the question of how mindfulness training could produce such widespread and varied benefits. One possibility is that mindfulness practice results in beneficial changes in the nervous system.

 

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. The changes are complex and require sophisticated brain scanning techniques to detect. Hence there is a need to continue investigating the nature of these changes in the brain produced by meditation.

 

In today’s Research News article “Differences in Functional Connectivity of the Insula Between Brain Wave Vibration in Meditators and Non-meditators.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6244630/ ), Jang and colleagues recruited meditation practitioners and meditation naïve participants. The meditation practitioners had been practicing Brain Wave Meditation daily for at least a year. This meditation technique “is designed to help quiet the thinking mind and release negative emotions by performing specific rhythmic physical movements and focusing on bodily sensations.” The participants then underwent resting functional Magnetic Resonance Imaging (fMRI) of their brains.

 

They found that in comparison to the meditation naïve controls the meditators had greater levels of functional connectivity between the Dorsolateral Prefrontal Cortex and the Insula and Thalamus. There was also increased functional connectivity between the Insula and the Superior Temporal Gyrus. The Insula Cortex is thought to be involved in interoceptive awareness, that is the awareness of the body and the sensations from the body. The Thalamus is the major sensory relay in the brain transferring sensory information throughout the brain. The Prefrontal Cortex is thought to be involved in attention and higher-level thinking, cognition.

 

The findings, then, suggest that meditation practice changes the brain in such a way as to improve attention and thought processes regarding internal sensations. This implies better attention to emotional states and better ability to regulate emotions. Indeed, it has been well established that meditation practice improves attention, high level thinking and emotion regulation. This, in turn, may underlie the increases in compassion toward the self and others that has been shown to occur in meditators. Better emotion regulation would increase psychological and physical well-being of practitioners. Thus, some of the benefits of meditation appear to be reflected in changes to the brain which may underlie these benefits.

 

So, improve brain connectivity with meditation.

 

an added bonus of meditating is that the connection between the helpful aspects of the Me Center (i.e. dorsomedial prefrontal cortex) – the part involved in processing information related to people we perceive as being not like us – and the bodily sensation center – involved in empathy – becomes stronger.” – Rebecca Gladding

Abstract

The majority of meditation involves focusing attention on internal events or sensations and becoming aware of emotions. The insula cortex, through a functional connection with the prefrontal cortex and other brain regions, plays a key role in integrating external sensory information with internal bodily state signals and emotional awareness. The purpose of this exploratory study was to examine the resting-state functional connectivity of the insula with other brain regions in meditation practitioners and control subjects. Thirty-five Brain Wave Vibration meditation practitioners and 33 controls without meditation experience were included in this study. All subjects underwent 4.68-min resting-state functional scanning runs using magnetic resonance imaging. The anterior and posterior insulae were chosen as seed regions for the functional connectivity map. Meditation practitioners showed significantly greater insula-related functional connectivity in the thalamus, caudate, middle frontal gyrus, and superior temporal gyrus than did controls. Control subjects demonstrated greater functional connectivity with the posterior insula in the parahippocampal gyrus. Our findings suggest that the practice of Brain Wave Vibration meditation may be associated with functional differences in regions related to focused attention, executive control, and emotional awareness and regulation.

Change the Brain to Reduce Anxiety with Meditation

Change the Brain to Reduce Anxiety with Meditation

 

By John M. de Castro, Ph.D.

 

“In mindfulness practice you have an opportunity—the mental time and space, if you will—to see more elements of the story, a richer picture. “You may see more clearly as you anticipate a difficult encounter what the underlying emotion is that’s triggered and how it’s showing up in your body.” In this way, you become aware of the full context of the story, like seeing a flower opening in slow-motion photography. With this awareness, over time “your solid belief in a storyline may begin to erode.” – Zindel Segal

 

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. Meditation practice has been found to improve the regulation of emotions and reduce difficult emotional states such as anxiety and depression.

 

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. Meditation practice has been shown to change the brain and the brain’s reaction to emotions. The activity of the amygdala in the brain is highly associated with emotions. Hence, it would appear likely that meditation practice may alter the amygdala’s activity in response to emotions.

 

In today’s Research News article “Atypical Anxiety-Related Amygdala Reactivity and Functional Connectivity in Sant Mat Meditation.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6288484/ ), Chen and colleagues recruited healthy highly experienced meditators and healthy meditation naive participants. The meditators practiced Sant Mat meditation for 4 hours per day and had been practicing for at least 4 years. They also had a vegetarian diet and abstained from alcohol. The meditation practice incorporated loving kindness meditation.

 

All participants were measured for their state anxiety and their trait anxiety. The participants viewed colorized pictures of faces while their brain activity was monitored with functional Magnetic Resonance Imaging (fMRI). They were asked to ignore everything about the faces except their color which they responded to with a button press. The faces were both male and female expressing either happy, fearful, or neutral emotions.

 

They found that the meditators were significantly less anxious than the controls in both state and trait anxiety and the greater the number of years of meditation experience the lower the levels of anxiety. The meditators were also significantly slower in responding to the faces color. Slower responding has been associated with lower anxiety. It is well documented that meditation practice lowers anxiety. So, the lower levels in the meditators and slower responding were expected.

 

In terms of the brain amygdala responses to the face stimuli, the meditators had significantly lower responses regardless of the emotion portrayed. In addition, the meditators had a stronger amygdala response to happy faces than fearful faces while the controls had the opposite pattern with higher amygdala responses to fearful faces than happy faces. Mediation analysis indicated that the years of meditation experience was directly related to lower anxiety but the amygdala response partly meditated the effect such that the more years of meditation experience the lower the response of the amygdala and the lower the levels of anxiety.

 

These are interesting and entirely consistent results. The amygdala is known to be involved in emotionality. The results suggest that meditation experience alters the amygdala to respond less to emotional stimuli and to respond more to positive emotional stimuli than negative emotional stimuli. These lower responses may be the source of the effect of meditation practice of improved regulation of emotions. The greater responses of the amygdala in meditators to positive emotional stimuli may be the source of the effect of meditation practice of increased happiness.

 

It needs to be recognized that the meditators also had vegetarian diets and abstained from alcohol while the meditation naïve participants did not. It is possible that the differences observed stemmed from these differences rather than the meditation. It should also be noted that the meditators practiced 4 hours per day which is much more than most meditators, placing these meditators as outliers of amounts of meditation practice. Whether similar results may be observed with lower levels of meditation practice should be an important question for future research.

 

So, change the brain to reduce anxiety with meditation.

 

To me, this amazing brain science and the very real rewards gained from meditation combine to form a compelling argument for developing and/or maintaining a daily practice. It definitely motivates me on those days I don’t “feel” like sitting. So, try to remind yourself that meditating every day, even if it’s only 15 minutes, will keep those newly formed connections strong and those unhelpful ones of the past at bay.” – Rebecca Gladding

Abstract

While meditation has drawn much attention in cognitive neuroscience, the neural mechanisms underlying its emotional processing remains elusive. Sant Mat meditators were recruited, who adopt a loving-kindness mode of meditation along with a vegetarian diet and an alcohol-restricted lifestyle and novices. We assessed their State-Trait Anxiety Inventory (STAI) and scanned their amygdala reactivity in response to an explicit and implicit (backward masked) perception of fearful and happy faces. In contrast with novices, meditators reported lower STAI scores. Meditators showed stronger amygdala reactivity to explicit happiness than to fear, whereas novices exhibited the opposite pattern. The amygdala reactivity was reduced in meditators regardless of implicit fear or happiness. Those who had more lifetime practice in meditation reported lower STAI and showed a weaker amygdala response to fear. Furthermore, the amygdala in meditators, relative to novices, had a stronger positive functional connectivity with the ventrolateral prefrontal cortex (PFC) to explicit happiness, but a more negative connectivity with the insula and medial orbitofrontal cortex (OFC) to explicit fear. Mediation analysis indicated the amygdala reactivity as the mediator for the linkage between meditation experience and trait anxiety. The findings demonstrate the neural correlates that underpin the beneficial effects of meditation in Sant Mat. Long-term meditation could be functionally coupled with the amygdala reactivity to explicit and implicit emotional processing, which would help reduce anxiety and potentially enhance well-being.
