Spirituality is Associated with Better Mental and Physical Health and Cognitive Ability in African Americans

 

By John M. de Castro, Ph.D.

 

“all black religious expression has most of the following attributes: It is animistic, or spirit-filled; anthropocentric, or human-centered; dynamic; expressionistic; shamanistic (believing in communicating with spirits); and thaumaturgic (belief in miracle working).” – Diana Hayes

 

The immune system is designed to protect the body from threats like stress, infection, injury, and toxic chemicals. One of its tools is the Inflammatory response. This response works quite well for short-term infections and injuries. But when inflammation is protracted and becomes chronic, it can itself become a threat to health. It can produce autoimmune diseases such as colitis, Chron’s disease, arthritis, heart disease, increased cancer risk, lung disease, sleep disruption, gum disease, decreased bone health, psoriasis, and depression. Needless to say, chronic inflammation can create major health problems. Indeed, the presence of chronic inflammation is associated with reduced longevity. So, it is important for health to control the inflammatory response, allowing it to do its job in fighting off infection but reducing its activity when no external threat is apparent.

 

Depression is linked with increase inflammatory responses. Mind-body techniques such as yoga, Tai Chi and meditation have been shown to adaptively reduce the inflammatory response.  In addition, spirituality has been shown to be associated with reduced depression. African Americans have significantly greater incidences of disease. So, it is reasonable to investigate the relationships of spirituality, depression, inflammation and health in African Americans.

 

In today’s Research News article “Influence of Spirituality on Depression-Induced Inflammation and Executive Functioning in a Community Sample of African Americans.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6478044/), Herren and colleagues recruited healthy adult African Americans and measured them for depression, daily spiritual experiences, cognitive ability, and response inhibition. Blood was drawn and measured for inflammatory cytokines; IL-1a, TNF-a and IL-6.

 

They found that the higher the levels of depression the lower the levels of cognitive ability (executive function). This relationship was in part mediated by the levels of the inflammatory cytokine, IL-6, such that depression was associated with higher levels of IL-6 which in turn were associated with lower cognitive ability. Interestingly, they also found that the higher the frequency of daily spiritual experiences the lower the levels of depression and the higher the levels of cognitive ability and response inhibition. In addition, spirituality moderated the relationships of IL-6 with cognitive ability, such that the greater the frequency of spiritual experiences the smaller the negative relationship of IL-6 with cognitive ability.

 

These findings are interesting but they are correlational and causation cannot be determined. But they suggest that spirituality is associated with better physical and psychological health in African Americans. It is associated with lower depression levels and better cognitive performance. Additionally, it was associated with a lessened negative relationship between the inflammatory response and cognitive ability.

 

African Americans are generally more religious and spiritual than other groups. The present findings may help to explain why. Their spirituality is associated with better mental and physical health and cognitive ability. It remains for future research to determine if these relationships are causal and spirituality produces these benefits. It also remains to be seen if these relationships are present in other ethnic and racial groups.

 

Spirituality is associated with better mental and physical health and cognitive ability in African Americans.

Influence of Spirituality on Depression-Induced Inflammation and Executive Functioning in a Community Sample of African Americans. Ethnicity & disease, 29(2), 267–276. doi:10.18865/ed.29.2.267

 

Abstract

African Americans (AAs) are disproportionately affected by cerebrovascular pathology and more likely to suffer from premature cognitive decline. Depression is a risk factor for poorer cognitive functioning, and research is needed to identify factors that serve to mitigate its negative effects. Studies have demonstrated positive influences of spirituality within the AA community. Determining whether spirituality attenuates the effects of depressive symptoms on cognitive functioning and the pathophysiological mechanisms that explain these relationships in AAs is paramount. This study examines the influence of daily spiritual experiences on the relationship between depressive symptoms and cognitive functioning, and how inflammatory markers may partially explain these associations. A sample of 212 (mean age= 45.6) participants completed the Daily Spiritual Experience Scale (DSES), Beck Depression Inventory-II (BDI-II), Trail Making Test A and B (TMT) and Stroop Color and Word Test (Stroop). Blood samples were collected to measure inflammatory mediators (IL-6, IL-1a, TNF-a). Linear regression analyses were used to evaluate associations. Higher BDI-II scores were associated with poorer psychomotor speed and visual scanning, measured by TMT A (B=1.49, P=.01). IL-6 explained a significant amount of variance in this relationship (B=.24, CI 95% [.00, .64]). IL-6 also significantly mediated the relationship between depressive symptoms and psychomotor speed and mental flexibility, measured by TMT B performance (B=.03, CI 95% [.003, .095]). Frequent spiritual experiences among AAs may ameliorate the negative influence of depressive symptoms on cognitive functioning.

Improve Cardiac Function in Heart Failure Patients with Tai Chi

Improve Cardiac Function in Heart Failure Patients with Tai Chi

 

By John M. de Castro, Ph.D.

 

“Tai chi may be a useful form of exercise for cardiac rehab programs, as it’s safe for high-risk patients. Findings also suggest that tai chi alone may be beneficial for patients who are unwilling to participate in a rehab program.” – CardioSmart

 

Cardiovascular disease is the number one killer, claiming more lives than all forms of cancer combined. There are myriads of treatments that have been developed to treat Heart Failure including a variety of surgical procedures and medications. Importantly, lifestyle changes have proved to be quite effective. These include quitting smoking, weight reduction, improved diet, physical activity, and reducing stresses. Contemplative practices, such as meditation, tai chi, and yoga, have also been shown to be helpful for heart health. These practices have also been shown to be helpful for producing the kinds of other lifestyle changes needed such as smoking cessation, weight reduction and stress reduction.

 

Cardiac rehabilitation programs for patients recovering from a heart failure, emphasize these lifestyle changes. Unfortunately, for a variety of reasons, 60% of heart failure patients decline participation, making these patients at high risk for another attack.  Tai Chi and Qigong are ancient mindfulness practices involving slow prescribed movements. They are gentle and completely safe, can be used with the elderly and sickly, are inexpensive to administer, can be performed in groups or alone, at home or in a facility or even public park, and can be quickly learned. In addition, they can also be practiced in social groups without professional supervision. This can make it fun, improving the likelihood of long-term engagement in the practice. Since Tai Chi is both a mindfulness practice and an exercise, it may be an acceptable and effective treatment for heart failure patients.

 

In today’s Research News article “Tai Chi exercise and functional electrical stimulation of lower limb muscles for rehabilitation in older adults with chronic systolic heart failure: a non-randomized clinical trial.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6886363/), Hao and colleagues recruited elderly (>70 years) heart failure patients and assigned them to receive either 1-hour, twice a week, for 12 weeks Tai Chi practice or 30-minutes, five times per week of functional electrical stimulation of lower limb muscles (FEW), or both Tai Chi and FES, or to a no-treatment control condition. They were measured before and after the interventions for quality of life, depression, arterial flow mediated dilatation, mobility, and peak oxygen consumption.

 

They found that in comparison to the control group, all interventions groups had improved quality of life and cardiorespiratory functions. They had significantly improved arterial flow mediated dilatation; a measure associated with lower mortality in heart failure patients. The Tai Chi group also had decreased resting heart rate which, in turn, reduced peak oxygen consumption.

 

The results suggest that both Tai Chi practice and functional electrical stimulation of lower limb muscles improves the quality of life and cardiorespiratory functions in elderly heart failure patients. Additionally, Tai Chi practice lowered heart rates suggesting improved physical fitness. Hence, these interventions are recommended for the treatment of elderly heart failure patients.

Tai Chi, however, may be preferred due to its high levels of adherence and enjoyability.

 

So, improve cardiac function in heart failure patients with Tai Chi.

 

“it’s a reasonable and safe step to offer tai chi within cardiac rehab. If someone says they are afraid of exercising, we could ask if they are interested in doing tai chi.” – Elena Salmoriago-Blotcher

Abstract

Exercise-based training decreases hospitalizations in heart failure patients but such patients have exercise intolerance. The objectives of the study were to evaluate the effect of 12 weeks of Tai Chi exercise and lower limb muscles’ functional electrical stimulation in older chronic heart failure adults. A total of 1,084 older adults with chronic systolic heart failure were included in a non-randomized clinical trial (n=271 per group). The control group did not receive any kind of intervention, one group received functional electrical stimulation of lower limb muscles (FES group), another group practiced Tai Chi exercise (TCE group), and another received functional electrical stimulation of lower limb muscles and practiced Tai Chi exercise (FES & TCE group). Quality of life and cardiorespiratory functions of all patients were evaluated. Compared to the control group, only FES group had increased Kansas City Cardiomyopathy Questionnaire (KCCQ) score (P<0.0001, q=9.06), only the TCE group had decreased heart rate (P<0.0001, q=5.72), and decreased peak oxygen consumption was reported in the TCE group (P<0.0001, q=9.15) and FES & TCE group (P<0.0001, q=10.69). FES of lower limb muscles and Tai Chi exercise can recover the quality of life and cardiorespiratory functions of older chronic heart failure adult

Improve Obsessive-Compulsive Disorder with Kundalini Yoga Meditation

 

By John M. de Castro, Ph.D.

 

“mindfulness meditation had “a significant and large effect” on OCD symptoms, specifically on thought-action fusion (again, the belief that having a thought is the same as acting on the thought), and the ability to “let go” of unwanted thoughts.” – Jon Hershfield

 

Obsessive-Compulsive Disorder (OCD) sufferer have repetitive anxiety producing intrusive thoughts (obsessions) that result in repetitive behaviors to reduce the anxiety (compulsions). In a typical example of OCD, the individual is concerned about germs and is unable to control the anxiety that these thoughts produce. Their solution is to engage in ritualized behaviors, such as repetitive cleaning or hand washing that for a short time relieves the anxiety. The obsessions and compulsions can become so frequent that they become a dominant theme in their lives. Hence OCD drastically reduces the quality of life and happiness of the sufferer and those around them. About 2% of the population, 3.3 million people in the U.S., are affected at some time in their life.

Fortunately, OCD can be treated and mindfulness training has been shown to be effective in treating OCD.

 

In today’s Research News article “Kundalini Yoga Meditation Versus the Relaxation Response Meditation for Treating Adults With Obsessive-Compulsive Disorder: A Randomized Clinical Trial.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6859828/), Shannahoff-Khalsa and colleagues recruited healthy adults diagnosed with Obsessive-Compulsive Disorder (OCD) who did not respond to first line therapies. They were randomly assigned to weekly 2-hour trainings for 4.5 months of either Kundalini Yoga meditation or relaxation response meditation. They were instructed to practice at home for an hour daily. Kundalini Yoga meditation is a combination of exercise, meditation, and breathing exercises. Relaxation response meditations employs various techniques to produce deep muscle relaxation. After the 4.5-month period, the groups were combined and all participants practiced Kundalini Yoga meditation for 7.5 months. The participants were measured before and after the 4.5-month training and at 1 year for OCD symptoms, OCD severity, anxiety, depression, mood states, and physical and mental health.

 

They found that in comparison to relaxation response meditation the participants who practiced Kundalini Yoga meditation had significantly greater reductions in Obsessive-Compulsive Disorder (OCD) symptoms and severity, anxiety, depression, and mood states. The improvements were continued over the 1-year practice period. In addition, the participants who practiced Kundalini Yoga meditation had significantly higher (31%) OCD remission rates.

 

The patients in this study had not previously responded to treatment with drugs, cognitive behavioral therapy, or exposure and response prevention therapy. The present results suggest that Kundalini Yoga meditation is a safe and effective treatment for Obsessive-Compulsive Disorder (OCD) in these patients who were unresponsive to other OCD therapies. Future studies are needed to compare Kundalini Yoga meditation to first line treatments for OCD.

 

So, improve Obsessive-Compulsive Disorder with Kundalini Yoga Meditation.

 

“Mindfulness is a useful technique for decreasing anxiety because of its emphasis on accepting your thoughts. When an intrusive thought pops up, you let it exist in your mind without providing it any weight. You experience the thought, but don’t judge it, change it or try to make it go away. You wait until it passes instead of thinking it should or shouldn’t be there.” – IntrusiveThoughts.org

Study Summary

 

Shannahoff-Khalsa, D., Fernandes, R. Y., Pereira, C., March, J. S., Leckman, J. F., Golshan, S., … Shavitt, R. G. (2019). Kundalini Yoga Meditation Versus the Relaxation Response Meditation for Treating Adults With Obsessive-Compulsive Disorder: A Randomized Clinical Trial. Frontiers in psychiatry, 10, 793. doi:10.3389/fpsyt.2019.00793

 

Abstract

Background: Obsessive-compulsive disorder (OCD) is often a life-long disorder with high psychosocial impairment. Serotonin reuptake inhibitors (SRIs) are the only FDA approved drugs, and approximately 50% of patients are non-responders when using a criterion of 25% to 35% improvement with the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). About 30% are non-responders to combined first-line therapies (SRIs and exposure and response prevention). Previous research (one open, one randomized clinical trial) has demonstrated that Kundalini Yoga (KY) meditation can lead to an improvement in symptoms of obsessive-compulsive severity. We expand here with a larger trial.

Design: This trial compared two parallel run groups [KY vs. Relaxation Response meditation (RR)]. Patients were randomly allocated based on gender and Y-BOCS scores. They were told two different (unnamed) types of meditation would be compared, and informed if one showed greater benefits, the groups would merge for 12 months using the more effective intervention. Raters were blind in Phase One (0–4.5 months) to patient assignments, but not in Phase Two.

Main Outcome Measures: Primary outcome variable, clinician-administered Y-BOCS. Secondary scales: Dimensional Yale-Brown Obsessive Compulsive Scale (clinician-administered), Profile of Mood Scales, Beck Anxiety Inventory, Beck Depression Inventory, Clinical Global Impression, Short Form 36 Health Survey.

Results: Phase One: Baseline Y-BOCS scores: KY mean = 26.46 (SD 5.124; N = 24), RR mean = 26.79 (SD = 4.578; N = 24). An intent-to-treat analysis with the last observation carried forward for dropouts showed statistically greater improvement with KY compared to RR on the Y-BOCS, and statistically greater improvement on five of six secondary measures. For completers, the Y-BOCS showed 40.4% improvement for KY (N = 16), 17.9% for RR (N = 11); 31.3% in KY were judged to be in remission compared to 9.1% in RR. KY completers showed greater improvement on five of six secondary measures. At the end of Phase Two (12 months), patients, drawn from the initial groups, who elected to receive KY continued to show improvement in their Y-BOCS scores.

Conclusion: KY shows promise as an add-on option for OCD patients unresponsive to first line therapies. Future studies will establish KY’s relative efficacy compared to Exposure and Response Prevention and/or medications, and the most effective treatment schedule.

Improve Memory with Brief Breath Awareness Practice

Improve Memory with Brief Breath Awareness Practice

 

By John M. de Castro, Ph.D.

 

“Our in-breath is like a remote control for our brains, directly affecting electrical signals that communicate with memory and emotional processing centers.” – Crystal Goh

 

Breathing is essential for life and generally occurs automatically. It’s easy to take for granted as it’s been there our entire lives. Nevertheless, we become more aware of it when it varies with circumstances, such as when we exercise and also in emotional states, especially fear and anxiety. But we rarely notice it during everyday ongoing life. Yet, its characteristics are associated with our state of well-being. Slow deep breathing is characteristic of a healthy relaxed state. Breathing exercises are common in yoga practices and have been found to have a number of beneficial effects. There are a number of breathing exercises and there is a need to identify the psychological effects of each.

 

In today’s Research News article “Performance in a Corsi Block-tapping Task following High-frequency Yoga Breathing or Breath Awareness.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6746049/), Gupta and colleagues recruited young (aged 18-24 years) volunteers who had at least 3 months of experience with yogic breathing techniques. They were randomly assigned to different orders of 3 conditions; high frequency yogic breathing, breath awareness, or quiet sitting. The conditions occurred in 5-minute blocks separated by 1-minute rest.

 

Memory was measured with a Corsi Blocks task in which nine blue squares are presented and then each square changes to yellow in a random sequence. The participants task is to reproduce the sequence in either forward or backward order. The number of blocks changing color began at 2 and increased to 9. The task was terminated when the participant failed twice to reproduce the order of a particular size.

 

They found that neither the high frequency yogic breathing nor the quiet sitting produced a significant change in performance on the Corsi Blocks task. On the other hand, after the breath awareness condition there was a significant improvement in the backward order scores.

 

The study involves only an extremely brief task. It cannot be concluded that breath awareness would have any lasting effect or that training in breath awareness over time would produce lasting memory improvement. Nevertheless, these results suggest that a brief breath awareness practice improves memory ability immediately afterward.

 

So, improve memory with brief breath awareness practice.

Abstract

Background:

Uninostril yoga breathing practices have improved spatial memory scores. There has been no assessment on the effect of high-frequency yoga breathing (HFYB) on working memory and spatial memory scores using the Corsi block-tapping task (CBTT).

Objectives:

The present study was planned to assess the immediate effects of HFYB and breath awareness (BAW) compared to a control session on performance in a CBTT.

Methods:

Fifteen participants of both sexes with ages between 18 and 24 years (group mean age ± standard deviation, 20.0 ± 1.6 years; 10 females) were recruited for the trial from a university in North India. Each participant was assessed in three sessions conducted on 3 separate days at the same time of the day. The three sessions were (i) HFYB, (ii) BAW, and (iii) quiet sitting (QS). The duration of the intervention was 18 min. The participants were assessed before and after all the three sessions. Repeated-measures-analyses of variance followed by post hoc tests with Bonferroni adjustment were performed to compare data before and after all the three sessions.

Results:

BAW resulted in an improvement in backward total scores (P < 0.05) and the backward Corsi span (P < 0.05; one tailed).

Conclusions:

The results suggest that BAW improves primary working memory, spatial memory, and spatial attention. HFYB did not cause any change.

Further Improve Depression Treated with Drugs and Counseling with Yoga

Further Improve Depression Treated with Drugs and Counseling with Yoga

 

By John M. de Castro, Ph.D.

 

“I feel like the creator of my own reality, rather than the victim of my own circumstance. Yoga has also allowed me to form healthy boundaries and relationships without the highs and the lows.” – Kacey DeGuardia

 

Depression affects over 6% of the population. Depression can be difficult to treat. It is usually treated with antidepressant medication. But, of patients treated initially with drugs only about a third attained remission of the depression. After repeated and varied treatments including drugs, therapy, exercise etc. only about two thirds of patients attained remission. But drugs often have troubling side effects and can lose effectiveness over time. Being depressed and not responding to treatment or relapsing is a terribly difficult situation. The patients are suffering and nothing appears to work to relieve their intense depression. Suicide becomes a real possibility. So, it is imperative that other treatments be identified that can relieve the suffering.

 

Mindfulness training is an alternative treatment for depression. It has been shown to be an effective treatment for depression and its recurrence and even in the cases where drugs fail.  Another effective alternative treatment is exercise. But it is difficult to get depressed people, who lack energy, to engage in regular exercise. Yoga is a contemplative practice that is both a mindfulness practice and an exercise. It has been shown to be effective in the treatment of depression. So, it makes sense to further study the effectiveness of yoga for depression.

 

In today’s Research News article “Effect of adjunct yoga therapy in depressive disorders: Findings from a randomized controlled study.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6862972/), Kumar and colleagues recruited adult patients diagnosed with depression and randomly assigned them to either receive standard treatment or standard treatment plus yoga therapy. Standard treatment included antidepressant medication and counseling. Yoga therapy sessions included training in breath awareness, postures, and mindful relaxation and occurred 5 times per week for 45 minutes for 4 weeks. They were measured before, during, and after treatment for depression, anxiety, depression severity, and clinical improvement.

 

They found that in comparison to baseline and the treatment as usual control condition, the group who received yoga therapy had significantly decreased depression, anxiety, and depression severity, and a significant increase in clinical improvement. These results are encouraging and suggest that yoga therapy works to improve depression even in patients continuing to receive drugs and counseling.

 

Yoga therapy is a complex technique including training in breath awareness, various postures, and mindful relaxation. Future research needs to examine which of these components or combination of components of the yoga therapy program are necessary and sufficient for the improvement. In addition, there’s a need to study the long-term effectiveness of yoga therapy. The results, however, suggest that yoga therapy is safe and effective as an adjunctive treatment for depression producing further improvements.

 

So, further improve depression treated with drugs and counseling with yoga.

Abstract

Background:

Depression causes significant burden both to the individual and to society, and its treatment by antidepressants has various disadvantages. There is preliminary evidence that adds on yoga therapy improves depression by impacting the neurotransmitters involved in the regulation of mood, motivation, and pleasure. Our study aimed to find the effect of adjunctive yoga therapy on outcome of depression and comorbid anxiety.

Materials and Methods:

A randomized controlled study involving patients with major depressive disorder (n = 80) were allocated to two groups, one received standard therapy (antidepressants and counseling) and the other received adjunct yoga therapy along with standard therapy. Ratings of depression and anxiety were done using Montgomery–Asberg Depression Rating Scale and Hospital Anxiety and Depression Scale at baseline, 10th and 30th day. Clinical Global Impression (CGI) Scale was applied at baseline and 30th day to view the severity of illness and clinical improvement.

Results:

By the 30th day, individuals in the yoga group had significantly lower scores of depression, anxiety, and CGI scores, in comparison to the control group. The individuals in the yoga group had a significant fall in depression scores and significant clinical improvement, compared to the control group, from baseline to 30th day and 10th to 30th day. In addition, the individuals in the yoga group had a significant fall in anxiety scores from baseline to 10th day.

Conclusion:

Anxiety starts to improve with short-term yoga sessions, while long-term yoga therapy is likely to be beneficial in the treatment of depression.

Improve Emotion Processing with Brief Short-Term Meditation

Improve Emotion Processing with Brief Short-Term Meditation

 

By John M. de Castro, Ph.D.

 

“brief mindfulness meditation, but not deliberate engagement in state mindfulness, produces demonstrable changes in emotional processing indicative of reduced emotional reactivity,” – Yanli Lin

 

Mindfulness practice has been shown to improve emotions and their regulation. Practitioners demonstrate more positive and less negative emotions and the ability to fully sense and experience emotions, while responding to them in appropriate and adaptive ways. In other words, mindful people are better able to experience yet control their responses to emotions. The ability of mindfulness training to improve emotion regulation is thought to be the basis for a wide variety of benefits that mindfulness provides to mental health and the treatment of mental illness especially depression and anxiety disorders. Dose-response, however, has not been explored and it is not known how much meditation practice is needed to produce emotional benefits.

 

In today’s Research News article “Brief Mindfulness Meditation Improves Emotion Processing.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6795685/), Wu and colleagues recruited physically and mentally healthy nom- meditating university students and randomly assigned them to a daily, 15 minutes, for 7 days of either mindfulness meditation or a course on emotional awareness. They were measured before and after treatment for anxiety, and depression. They also viewed a set of emotionally positive, negative or neutral pictures and were measured for their reactions of emotion intensity, emotional memory, and emotional attentional bias.

 

They found that the meditation group did not change in depression levels while the emotional awareness group increased in depression producing a significant difference between the groups. The meditation group had significant reductions in both positive and negative emotional intensity following the intervention while the emotional awareness group had a significant increase in negative emotional intensity. Following the intervention, the meditation group demonstrated a significant decrease in negative and a significant increase in positive emotional attentional bias while the emotional awareness group had a significant decrease in positive and emotional attentional bias.

 

These results are in line with prior research in demonstrating mindfulness training producing significant improvements in depression and emotional regulation. The results, however, are particularly interesting as the meditation intervention was brief and short-term, yet had significant impacts on mood and emotional regulation. Hence, a relatively small dose of meditation practice is sufficient to produce emotional benefits. The control condition was an active control condition, which is a strength. But it may have produced increased attention to emotions increasing reactions to them. Regardless, the study demonstrates that mindfulness meditation can have beneficial effects on emotions and their regulation even after only brief and short-term practice.

 

So, improve emotion processing with brief short-term meditation.

Abstract

Mindfulness-based interventions have previously been shown to have positive effects on psychological well-being. However, the time commitment, teacher shortage, and high cost of classic mindfulness interventions may have hindered efforts to spread the associated benefits to individuals in developing countries. Brief mindfulness meditation (BMM) has recently received attention as a way to disseminate the benefits of mindfulness-based interventions. Most existing BMM methods are adaptations of the classic approach. Few studies have investigated the mechanisms underlying the beneficial effects of BMM. We developed a 15-min BMM named JW2016, which is based on the core concepts of mindfulness, Anapanasati (breath meditation of Buddhist Vipassana), our practical experience, and the results of scientific reports on meditation. We investigated the effects of this BMM on mood and emotion processing in an effort to create an effective, convenient, safe, and standardized BMM method that could benefit individuals with limited time or money to devote to meditation. Forty-six healthy participants (aged 18–25 years) were randomly allocated to the BMM group (n = 23) or the emotional regulation education (ERE) control group (n = 23). Forty-two of the study participants cooperated fully in all measurements and interventions (one time daily for seven consecutive days). Mood was measured with the Centre for Epidemiological Studies–Depression scale (CES-D) and the State Anxiety Inventory (SAI). Emotion processing was evaluated by assessing performance on an emotion intensity task, an emotional memory task, and an emotional dot-probe task. After intervention, the BMM group, but not the ERE group, showed a significant decreases in emotional intensity in response to positive as well as negative emotional stimuli, response time for emotional memory, and duration of attention bias toward negative emotional stimuli. Negative effects on mood state were found in the ERE group but not in the BMM group. This study demonstrated that BMM may improve aspects of emotion processing such as emotion intensity, emotional memory, and emotional attention bias. JW2016 BMM may be an effective, convenient, safe and standardized way to help practitioners remain focused and peaceful without any negative effect on emotion.

Improve the Symptoms of Diabetic Neuropathy with Mindfulness

 

By John M. de Castro, Ph.D.

 

“Daily mindfulness practice can be helpful for people living with chronic pain because sometimes there are negative or worrisome thoughts about the pain. These thoughts are normal, and can affect mood and increase pain. Being able to focus on relaxing the body, noticing the breath and body sensations as being there just as they are, can help manage pain, as well as reduce depression and anxiety symptoms.” – Mayo Clinic

 

Diabetes can lead to a very painful condition known as diabetic neuropathy. The high blood glucose levels associated with diabetes can damage nerves and result in a burning pain and numbness, particularly from the legs and feet. It affects the majority of long-term diabetes patients. This is not only painful but is also disruptive to the normal life functions of these patients. There are no cures, but diabetic neuropathy can be prevented by blood glucose control in the diabetic patient with a rigorous program of measured diet and exercise. Treatment for diabetic neuropathy usually involves pain management with drugs.

 

Mindfulness practices have been shown to help with pain management and with quality of life in diabetes patients. and has been shown to improve the symptoms of diabetic neuropathy. It is important, then, to continue studying the effectiveness of mindfulness practices for reducing pain and improving quality of life in patients with diabetic neuropathy.

 

In today’s Research News article “Mindfulness-Based Meditation Versus Progressive Relaxation Meditation: Impact on Chronic Pain in Older Female Patients With Diabetic Neuropathy.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6757487/), Hussain and Said recruited elderly females with diabetes. They were randomly assigned to one of three condition, Mindfulness-Based Cognitive Therapy (MBCT), progressive muscle relaxation training, or a control condition consisting of 15 minutes of discussion and 20 minutes of quiet sitting. Treatment occurred twice a week for 8 weeks. MBCT consists of mindfulness training and Cognitive Behavioral Therapy (CBT). During therapy the patient is trained to investigate and alter aberrant thought patterns underlying their reactions to their neuropathy. The participants were measured before and after training for pain, analgesia, impression of change in their condition, and patient satisfaction.

 

They found that in comparison to baseline and the control group both the Mindfulness-Based Cognitive Therapy (MBCT) and progressive muscle relaxation groups had significant reductions in daily pain intensity and significant enhanced impression of change in their condition. In addition, the MBCT group had significant improvement in their satisfaction with treatment.

 

These results suggest that both Mindfulness-Based Cognitive Therapy (MBCT) and progressive muscle relaxation improve the daily pain of elderly female diabetic neuropathy patients and their perception of improvement in their condition. MBCT  would appear to be somewhat superior to progressive relaxation in improving the condition. This is important as these patients suffer greatly and the pain interferes with their ability to conduct their lives. The pain relief is most welcome.

 

So, improve the symptoms of diabetic neuropathy with mindfulness.

 

“in addition to improving pain, mindfulness also addresses the psychological consequences of chronic pain, including depression symptoms.” -0 Shanna Patterson

Abstract

Chronic pain, the most common complication of diabetes, is treated with medication often to no avail. Our study aimed to compare the use of mindfulness meditation and progressive relaxation to reduce chronic pain in older females with diabetes. Methods The 105 study participants were divided randomly into 3 groups: Group MM (mindfulness meditation), Group CM (control meditation), and Group PM (progressive relaxation meditation). Assessment of analgesic effectiveness required changes in average daily pain Brief Pain Inventory (BPI) modified for painful diabetic peripheral neuropathy and Patient Global Impression of Change using descriptive statistics, Student’s t test, and analysis of variance where applicable. Results Both Groups MM and PM experienced significant (P < .05) reduction in average daily pain in last 24 hours at study end compared to baseline (28.7% and 39.7%, respectively). Group MM had more significant (P < .01) reduction of pain compared to control, a score of 5.2 ± 1.2 dropped to 3.0 ± 1.1 by week 12 of treatment. Groups MM and PM showed significant improvement in patients’ impression at study end, 75 ± 5.1% (n = 36) and 61 ± 6.5% (n = 32), respectively. In Group MM, patient satisfaction scores increased significantly (P < .05) to 3.8 ± 1.9 by week 12. Conclusion Integrative therapies such as mindfulness meditation can be part of a comprehensive pain management plan. Benefits include reduction of pain-related medication consumption, better treatment outcomes, improvement in comorbid conditions such as anxiety and depression as well as no risk of addiction or abuse.

Enhance Relaxation and Reduce Stress with a Brief Sound Meditation

Enhance Relaxation and Reduce Stress with a Brief Sound Meditation

By John M. de Castro, Ph.D.

 

“Sound meditation is the use of therapeutic instruments played in an intuitive way.  It’s an extremely effective and powerful tool for physical and energetic healing/self care. You don’t just hear the vibrations but you FEEL them within your body.” – Babeskills

 

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

 

There are a number of different types of meditation. Many can be characterized on a continuum with the degree and type of attentional focus. In focused attention meditation, the individual practices paying attention to a single meditation object, learns to filter out distracting stimuli, including thoughts, and learns to stay focused on the present moment, filtering out thoughts centered around the past or future. There are a variety of objects of focused meditation, the most common of which is focusing on the breath. But focusing on sounds can also be very effective.

 

In today’s Research News article “Didgeridoo Sound Meditation for Stress Reduction and Mood Enhancement in Undergraduates: A Randomized Controlled Trial.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6769210/), Philips and colleagues recruited meditation naïve college students and randomly assigned them to a single 30 minute meditation session focusing on either sound or the breath. The sound meditation occurred to music played on a Didgeridoo. They were measured before and after the session for mood and perceived stress.

 

They found that after the meditation both groups had significant increases in relaxation and energy and decreases in negative arousal, tiredness, and perceived stress. But the sound meditation group had significantly greater increases in relaxation and decreases in perceived stress than the breath meditation group. The students reported enjoying the meditation but the sound meditation group reported significantly greater enjoyment than the breath meditation group.

 

The results of the study suggest that a single brief meditation session can improve mood and reduce perceived stress but that meditating to music played on a Didgeridoo produced greater relaxation and greater reductions in perceived stress that a more traditional meditation focused on the breath. It appears that the Didgeridoo music made for a more enjoyable meditation. It is possible that the effects observed were due to making meditation more enjoyable rather than a superiority of sound meditation. Future research needs to explore whether these effects occur to different sounds varying in enjoyability and are maintained with a greater number of meditation sessions.

 

So, enhance relaxation and reduce stress with a brief sound meditation.

 

“Sound enhances our self-awareness, it facilitates connecting with the higher self, it promotes self-observation and self-worth, and it increases the state of personal resonance. It brings awareness to the inner processes of the mind: the habitual patterns, the good and bad discursive thinking, the judgment, the filters through which we experience the inner and the outer worlds and realities.” – SoundMeditation.com

Short abstract

Background

College students report feeling frequently stressed, which adversely impacts health. Meditation is one effective method for reducing stress, but program length and required effort are potential obstacles. Research on sound meditation, involving focused listening to sounds, is nascent but may appeal to undergraduates. The effects of listening to didgeridoo, an Australian wind instrument producing a low, resonant, droning sound, have not been studied.

Objective

This study compared the effect of a 30-minute didgeridoo sound meditation versus silent meditation with focus on one’s breath on acute self-perceived stress and mood in undergraduates without prior meditation experience.

Methods

Seventy-four undergraduates were randomized to 2 interventions: (1) didgeridoo meditation (n = 40) performed live by a musician or (2) silent meditation (n = 34) taught by a meditation instructor. Immediate pre–post effects of the session were examined using the 4-Dimension Mood Scale and an item assessing acute self-perceived stress. Intervention acceptability was assessed postintervention.

Results

Two-way mixed analyses of variance were performed. Both groups reported significantly increased relaxation after meditation (Group D, P = .0001 and Group S, P = .0005). Both groups reported decreased negative arousal (Group D, P = .02 and Group S, P = .02), energy (Group D, P = .0001 and Group S, P = .003), tiredness (Group D, P = .0001 and Group S, P = .005), and acute stress (Group D, P = .0001 and Group S, P = .0007). Group Didgeridoo experienced significantly more relaxation (P = .01) and less acute stress (P = .03) than Group Silent. Fifty-three percent of silent participants and 80% of didgeridoo participants agreed that they would attend that type of meditation again. Forty-seven percent of silent participants and 80% of didgeridoo participants enjoyed the meditation.

Conclusion

Didgeridoo sound meditation is as effective as silent meditation for decreasing self-perceived negative arousal, tiredness, and energy and more effective than silent meditation for relaxation and acute stress in undergraduates. Didgeridoo meditation participants reported higher levels of enjoyment and higher likelihood of attending another session. Further investigation into didgeridoo and sound meditation is warranted.

Improve Vascular Function and blood Pressure with Meditation

Improve Vascular Function and blood Pressure with Meditation

 

By John M. de Castro, Ph.D.

 

“Studies have also linked meditation to healthier arteries and improved blood flow to the heart.” – CardioSmart

 

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

 

Obviously, there is a need for alternative to drug treatments for hypertension. Mindfulness practices have been shown to aid in controlling hypertension. Indeed, meditation, tai chi, and yoga, have also been shown to be helpful for heart health. These practices have also been shown to reduce the physiological and psychological responses to stress and to be helpful for producing the kinds of lifestyle changes needed to prevent heart disease such as smoking cessation, and weight reduction. They have also been shown to be effective in maintaining cardiovascular health and the treatment of cardiovascular disease. Hence it is reasonable to review and summarize what has been learned concerning the effects of mindfulness training on cardiovascular health.

 

In today’s Research News article “Buddhist meditation for vascular function: A narrative review.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6881634/?report=classic), Amarasekera and colleagues review and summarize the published research studies on the effects of meditation on vascular endothelial function and blood pressure. They found 5 published research reports.

 

They report that the research found that meditation practice increased mindfulness and decreased stress and blood pressure, both systolic and diastolic. They also found that meditation improved vascular endothelial function, including a reduction in vascular stiffness and an increase in flow mediated dilatation. These benefits occurred in both old and young individuals.

 

The findings of the research to date suggests that meditation practice produces significant improvements in vascular function. This is particularly important as today’s sedentary life styles are associated with increased blood pressure and impaired vascular function which in turn is associated with poorer health. It is likely that the ability of meditation practice to increase mindfulness and to reduce the psychological and physiological responses to stress are responsible for the cardiovascular improvements.

 

So, improve vascular function and blood pressure with meditation.

 

“it is not the stress in our life, but the reaction to stress that is so potentially harmful to our health, including cardiovascular health. Hence . . . meditation and relaxation techniques are extremely important and useful to minimize these unhealthy reactions to stress.” – Joon Sup Lee

Abstract

Background

High blood pressure represents an important risk factor for diseases related to cardiovascular system and is directly associated with high oxidative stress, inflammation and vascular endothelial dysfunction. Recently, there is promising data available to suggest that meditation-based low-cost and low-risk lifestyle modification strategies may provide beneficial effects on chronic inflammation, oxidative stress and maintenance of blood pressure, both in young and older adults. This review aims to summarize the evidence regarding the effectiveness of Buddhist meditation for vascular endothelial function and blood pressure.

Method

A search was conducted using Ovid MEDLINE, Scopus, CINAHL and PsycINFO for articles published from 1990 to 2018.

Results

Relevant articles (n = 407) were reviewed and 5 met selection criteria. Several lines of studies have provided compelling data showing that Buddhist meditation approach was effective in improving inflammation and vascular function (endothelial vasodilation and arterial stiffness) in both young and elderly cohorts. Particularly, Buddhist meditation approach has shown to be effective in reducing plasma inflammatory markers, increasing nitric oxide concentration and improving vascular endothelial function and glycemic control, which in turn can be favorable factors for demonstrated positive effects of Buddhist meditation on blood pressure and vascular function.

Conclusion

This paper presents brief overview of clinical outcomes of complementary therapeutic approach of Buddhist meditation in vascular function. In future, well-structured systematic reviews are essential to report specificity of Buddhist mindfulness-based approach on vascular function, blood pressure and other cardiovascular risk factors.

Reduce Depression with Qigong Practice

Reduce Depression with Qigong Practice

 

By John M. de Castro, Ph.D.

 

“practice of the Chinese martial art tai chi led to significantly reduced symptoms of depression in Chinese-Americans not receiving any other treatments.” – Science Daily

 

Clinically diagnosed depression is the most common mental illness, affecting over 6% of the population. Depression can be difficult to treat and is usually treated with anti-depressive medication. But, of patients treated initially with drugs only about a third attained remission of the depression. After repeated and varied treatments including drugs, therapy, exercise etc. only about two thirds of patients attained remission. But drugs often have troubling side effects and can lose effectiveness over time. In addition, many patients who achieve remission have relapses and recurrences of the depression. Even after remission some symptoms of depression may still be present (residual symptoms).

 

Being depressed and not responding to treatment or relapsing is a terribly difficult situation. The patients are suffering and nothing appears to work to relieve their depression. Suicide becomes a real possibility. So, it is imperative that other treatments be identified that can relieve the suffering. Mindfulness training is an alternative treatment for depression. It has been shown to be an effective treatment for depression and its recurrence and even in the cases where drugs fail.  Mindful Movement practices such as Qigong and Tai Chi have been found to be effective for depression. Research has been accumulating. So, it is important to step back and examine what has been learned regarding the application of Qigong practice for depression.

 

In today’s Research News article “The Neurophysiological and Psychological Mechanisms of Qigong as a Treatment for Depression: 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/PMC6880657/?report=classic), So and colleagues review, summarize, and perform a meta-analysis of the published randomized controlled trials of Qigong practice for depression. They identified 9 published trials that included depression and biological measures.

 

They report that the research found that Qigong practice resulted in a significant reduction in depression with small to moderate effect sizes. They also report that there was a significant reduction in systolic blood pressure produced by  Qigong practice. There were indications that Qigong practice also reduced inflammation and stress hormones and increased well-being but there were insufficient studies to conduct a meta-analysis.

 

The results suggest that Qigong practice is a safe and mildly effective treatment for depression. There is a need for more research on the effects of Qigong practice on the biological processes that may underlie its effectiveness and also of the psychological well-being of the depressed individuals.

 

It’s important to note that Qigong is a gentle and safe mindfulness practice. It is appropriate for all ages including the elderly and for individuals with illnesses that limit their activities or range of motion. It is inexpensive to administer, can be performed in groups or alone, at home or in a facility, and can be quickly learned. In addition, it can be practiced in social groups. This can make it fun, improving the likelihood of long-term engagement in the practice.

 

So, reduce depression with Qigong practice.

 

“Qi Gong is one path for overcoming depression that has no harmful side effects. Furthermore, it can coincide with any other course of intervention or treatment.” – Ian Drogin

Abstract

Objective: An increasing number of studies have shown the anti-depressive effect of qigong. However, its underlying mechanism remains poorly understood. This study aims to systematically review and meta-analyze existing literature on the mechanism of qigong in reducing depression.

Method: The review process followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Randomized controlled trials of qigong were searched from PsycINFO, PubMed, Embase, ScienceDirect, and Academic Search Premier from inception to December 2018. Studies which involved depression and any neurophysiological or psychological mechanisms as outcomes were included. Publication bias was tested before conducting meta-analysis. Two independent raters were involved for the entire review process.

Results: A total of nine studies were identified which covered both neurophysiological and psychological mechanisms. Among these selected studies, seven were involved in meta-analysis, which suggested that qigong was effective in alleviating depression (standardized mean difference, SMD = −0.27, p < 0.05, I 2 = 27%). A significant effect was also found for diastolic blood pressure (SMD = −1.64, p < 0.05, I 2 = 31%). However, no significant effect was found for cortisol level and systolic blood pressure.

Conclusions: This review shows that qigong is effective in reducing depression through activating the parasympathetic nervous system. Future studies with higher quality of research methodology with less selection and attrition bias should be conducted to unravel the possible anti-depressive effect of qigong.
