Reduce Current Depressive Symptoms with Mindfulness

 

By John M. de Castro, Ph.D.

 

“Depression is not only the most common mental illness, it’s also one of the most tenacious. . . But a growing body of research is pointing to an intervention that appears to help prevent relapse by altering thought patterns without side effects: mindfulness-based cognitive therapy, or MBCT.” – Stacy Lu

 

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. 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 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. Mindfulness-Based Cognitive Therapy (MBCT) was specifically developed to treat depression. MBCT involves mindfulness training, containing sitting, walking and body scan meditations, and cognitive therapy that attempts to teach patients to distinguish between thoughts, emotions, physical sensations, and behaviors, and to recognize irrational thinking styles and how they affect behavior. MBCT has been found to be effective in treating depression. The research is accumulating. So, it makes sense to take a look at what has been learned.

 

In today’s Research News article “Mindfulness-based cognitive therapy for the treatment of current depressive symptoms: a meta-analysis.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6687569/ ) Goldberg and colleagues review, summarize, and perform a meta-analysis of the published randomized controlled trials of the effectiveness of Mindfulness-Based Cognitive Therapy (MBCT) for current depression. They identified 13 published controlled studies.

 

They report that the published studies found that Mindfulness-Based Cognitive Therapy (MBCT)  produced significant improvements in depressive symptoms when compared to non-specific control conditions; those that did not suggest therapeutic effects. On the other hand, compared to control conditions in which the condition was portrayed as therapeutic, MBCT produced equivalent reductions in depressive symptoms. They also report that the improvements do not last and were no longer present at follow-ups as long as 6 months post-treatment.

 

The results suggest that Mindfulness-Based Cognitive Therapy (MBCT)  is a safe and effective treatment for current depressive symptoms. But it does not appear to be superior to other therapies and does not have lasting efficacy. This suggests that further research needs to be performed to determine what are the components of therapy that produce improvements and which do not. They also suggest that booster treatments periodically after the primary treatment may be needed to maintain effectiveness.

 

So, reduce current depressive symptoms with mindfulness.

 

“Mindfulness-Based Cognitive Therapy (MBCT) is designed to help people who suffer repeated bouts of depression and chronic unhappiness. It combines the ideas of cognitive therapy with meditative practices and attitudes based on the cultivation of mindfulness.” – MBCT.com

Abstract

Mindfulness-based cognitive therapy (MBCT) appears to be a promising intervention for the prevention of relapse in major depressive disorder, but its efficacy in patients with current depressive symptoms is less clear. Randomized clinical trials of MBCT for adult patients with current depressive symptoms were included (k = 13, N = 1,046). Comparison conditions were coded based on whether they were intended to be therapeutic (specific active controls) or not (non-specific controls). MBCT was superior to non-specific controls at post-treatment (k = 10, d = 0.71, 95% CI [0.47, 0.96]), although not at longest follow-up (k = 2, d = 1.47, [−0.71, 3.65], mean follow-up = 5.70 months across all studies with follow-up). MBCT did not differ from other active therapies at post-treatment (k = 6, d = 0.002, [−0.43, 0.44]) and longest follow-up (k = 4, d = 0.26, [−0.24, 0.75]). There was some evidence that studies with higher methodological quality showed smaller effects at post-treatment, but no evidence that effects varied by inclusion criterion. The impact of publication bias appeared minimal. MBCT seems to be efficacious for samples with current depressive symptoms at post-treatment, although a limited number of studies tested the long-term effects of this therapy.

Improve Mental Health and Blood Biomarker Levels with Meditation and Yoga

Improve Mental Health and Blood Biomarker Levels with Meditation and Yoga

 

By John M. de Castro, Ph.D.

 

“The main purpose of meditation is to access, recognize and enhance the positive qualities of mind. The more we can do this, the less we need to rely on external situations for our happiness and the more we can rely on the natural, positive qualities of mind: love, contentment, well-being and peace.” – Trinlay Rinpoche

 

Over the last several decades, research and anecdotal experiences have accumulated an impressive evidential case that the development of mindfulness has positive benefits for the individual’s mental, physical, and spiritual life. Mindfulness appears to be beneficial both for healthy people and for people suffering from a myriad of mental and physical illnesses. It appears to be beneficial across ages, from children to the elderly. And it appears to be beneficial across genders, personalities, race, and ethnicity. The breadth and depth of benefits is unprecedented. There is no other treatment or practice that has been shown to come anyway near the range of mindfulness’ positive benefits.

 

It is not known exactly how mindfulness training produces these benefits. It is possible that one mechanism is by altering blood bourn hormonal levels. In today’s Research News article “Inner Engineering Practices and Advanced 4-day Isha Yoga Retreat Are Associated with Cannabimimetic Effects with Increased Endocannabinoids and Short-Term and Sustained Improvement in Mental Health: A Prospective Observational Study of Meditators.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7293737/ ) Sadhasivam and colleagues recruited healthy adults and had them attend a 4-day intensive training in yoga and meditation. Before and after the training and 1 month later they were measured for mindfulness, happiness, anxiety, depression, and psychological well-being. They also drew blood before and after training and assayed it for the brain-derived neurotrophic factor (BDNF), and the biomarkers of Endocannabinoids, (anandamide, 2-arachidonoylglycerol (2-AG), 1-arachidonoylglycerol (1-AG), docosatetraenoylethanolamide (DEA), and oleoylethanolamide (OLA)).

 

They found that after the training there were significant decreases in anxiety and depression and significant increases in mindfulness, happiness, and psychological well-being. These changes were maintained at the 1-month follow-up. There were also significant increases in all of the blood biomarkers of Endocannabinoids and also brain-derived neurotrophic factor (BDNF).

 

It should be kept in mind that this was a pilot study that did not have a control, comparison, condition. So, the results might have been due to a number of confounding factors rather than the training itself. But previous controlled research has convincingly demonstrated that mindfulness training increases happiness, and psychological well-being and decreases anxiety and depression. So, these changes were likely due to the training.

 

There were also novel findings in the present study that Endocannabinoids and brain-derived neurotrophic factor (BDNF) were significantly increased by the training. These provide objective measures of the subjective reports of psychological improvements. Endocannabinoids in the blood are associated with positive mood states. BDNF is a neurotrophic factor that is thought to signal neuroplastic changes in the nervous system. Mindfulness training has been previously shown to produce neuroplastic changes in the brain. So, the increases in these biomarkers indicate that the training not only improves the psychological health of the participants but also alters the brain, perhaps making the improvements longer lasting. This suggests a potential mechanism for the ability of meditation and yoga to improve mood, by increasing hormones that improve mood.

 

So, improve mental health and blood biomarker levels with meditation and yoga.

 

“The more you practice invoking states of well-being, the more available they are. Use the following practice to teach your mind and body to experience joy in the moment. As you invite happiness into your life in this way, you will have more access to a joyful life.” – Yoga Journal

Study Summary

 

Sadhasivam, S., Alankar, S., Maturi, R., Vishnubhotla, R. V., Mudigonda, M., Pawale, D., Narayanan, S., Hariri, S., Ram, C., Chang, T., Renschler, J., Eckert, G., & Subramaniam, B. (2020).

Abstract

Background

Anxiety and depression are common in the modern world, and there is growing demand for alternative therapies such as meditation. Meditation can decrease perceived stress and increase general well-being, although the physiological mechanism is not well-characterized. Endocannabinoids (eCBs), lipid mediators associated with enhanced mood and reduced anxiety/depression, have not been previously studied as biomarkers of meditation effects. Our aim was to assess biomarkers (eCBs and brain-derived neurotrophic factor [BDNF]) and psychological parameters after a meditation retreat.

Methods

This was an observational pilot study of adults before and after the 4-day Isha Yoga Bhava Spandana Program retreat. Participants completed online surveys (before and after retreat, and 1 month later) to assess anxiety, depression, focus, well-being, and happiness through validated psychological scales. Voluntary blood sampling for biomarker studies was done before and within a day after the retreat. The biomarkers anandamide, 2-arachidonoylglycerol (2-AG), 1-arachidonoylglycerol (1-AG), docosatetraenoylethanolamide (DEA), oleoylethanolamide (OLA), and BDNF were evaluated. Primary outcomes were changes in psychological scales, as well as changes in eCBs and BDNF.

Results

Depression and anxiety scores decreased while focus, happiness, and positive well-being scores increased immediately after retreat from their baseline values (P < 0.001). All improvements were sustained 1 month after BSP. All major eCBs including anandamide, 2-AG, 1-AG, DEA, and BDNF increased after meditation by > 70% (P < 0.001). Increases of ≥20% in anandamide, 2-AG, 1-AG, and total AG levels after meditation from the baseline had weak correlations with changes in happiness and well-being.

Conclusions

A short meditation experience improved focus, happiness, and positive well-being and reduced depression and anxiety in participants for at least 1 month. Participants had increased blood eCBs and BDNF, suggesting a role for these biomarkers in the underlying mechanism of meditation. Meditation is a simple, organic, and effective way to improve well-being and reduce depression and anxiety.

Improve Attention and the Brain Systems Underlying Attention with Meditation

Improve Attention and the Brain Systems Underlying Attention with Meditation

 

By John M. de Castro, Ph.D.

 

“the primary outcome of meditation may be to control attention and internal state in the face of the barrage of stimuli, negative and otherwise, that we experience everyday.” – Aaron D. Nitzkin

 

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

 

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

 

One method to observe attentional processing in the brain is to measure the changes in the electrical activity that occur in response to specific stimuli. These are called event-related, or evoked, potentials or ERPs. The signal following a stimulus changes over time. The fluctuations of the signal after specific periods of time are thought to measure different aspects of the nervous system’s processing of the stimulus. The P3 response in the evoked potential (ERP) is a positive going electrical response occurring between a 2.5 to 5 tenths of a second following the target stimulus presentation. The P3 component is thought to reflect attentional processing.

 

In today’s Research News article “Focused attention meditation training modifies neural activity and attention: longitudinal EEG data in non-meditators.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7304517/ ) Yoshida and colleagues recruited meditation-naïve college students and randomly assigned them to receive either focused meditation training or relaxation training, listening to classical music. The training occurred once a week for 30 minutes for 8 weeks. They also practiced meditation or relaxation at home for 10 minutes per day. They were measured before and after training for mindfulness. They also had brain activity measured with an electroencephalogram (EEG) before, during and after either a 5-minute meditation or relaxation and while performing an oddball task where they were asked to respond whenever a different tone the usual was presented. The evoked potentials to the tone presentations were recorded.

 

They found that in comparison to baseline and the relaxation group, the group that received focused meditation training had significantly faster reactions to the target stimuli during the oddball task. The evoked potentials to the oddball stimuli also demonstrated significantly larger P3 potentials in the meditation group. They also report that during meditation there was a significant increase in theta rhythm power in the EEG particularly in the frontal regions of the brain. They also found that only after 8 weeks of meditation training the greater the increase in theta power during meditation the smaller the increase in P3 magnitude during the oddball task.

 

These results suggest that meditation training produces an improvement in attention both behaviorally during the oddball task and also in the brain’s response to the stimuli. The results demonstrated that these changes occurred only after 8 weeks of meditation training and not after relaxation training. That mindfulness training improves attention and the P3 response in the evoked potential has been demonstrated previously.

 

Hence, meditation training in meditation-naïve college students improves attention both in the brain and in behavior. This improved attention should, although not investigated, produce improved performance in college academics. It remains for future research to investigate this hypothesis.

 

So, improve attention and the brain systems underlying attention with meditation.

 

“Nondirective meditation yields more marked changes in electrical brain wave activity associated with wakeful, relaxed attention, than just resting without any specific mental technique.” – ScienceDaily

Focused attention meditation training modifies neural activity and attention: longitudinal EEG data in non-meditators. Social cognitive and affective neuroscience, 15(2), 215–224. https://doi.org/10.1093/scan/nsaa020

 

Abstract

Focused attention meditation (FAM) is a basic meditation practice that cultivates attentional control and monitoring skills. Cross-sectional studies have highlighted high cognitive performance and discriminative neural activity in experienced meditators. However, a direct relationship between neural activity changes and improvement of attention caused by meditation training remains to be elucidated. To investigate this, we conducted a longitudinal study, which evaluated the results of electroencephalography (EEG) during three-stimulus oddball task, resting state and FAM before and after 8 weeks of FAM training in non-meditators. The FAM training group (n = 17) showed significantly higher P3 amplitude during the oddball task and shorter reaction time (RT) for target stimuli compared to that of the control group (n = 20). Furthermore, a significant negative correlation between F4-Oz theta band phase synchrony index (PSI) during FAM and P3 amplitude during the oddball task and a significant positive correlation between F4-Pz theta band PSI during FAM and P3 amplitude during the oddball task were observed. In contrast, these correlations were not observed in the control group. These findings provide direct evidence of the effectiveness of FAM training and contribute to our understanding of the mechanisms underpinning the effects of meditation on brain activity and cognitive performance.

Improve Stress-Related Neuropsychiatric Disorders with Yoga and Mindfulness

Improve Stress-Related Neuropsychiatric Disorders with Yoga and Mindfulness

 

By John M. de Castro, Ph.D.

 

“Mindfulness training holds promise for treating mood disorders partly because it may lead to changes in patients’ brains, improving connectivity among some brain areas and changing tissue density in key regions, research suggests.” – Stacy Lu

 

Over the last several decades, research and anecdotal experiences have accumulated an impressive evidential case that the development of mindfulness has positive benefits for the individual’s mental, physical, and spiritual life. Mindfulness appears to be beneficial both for healthy people and for people suffering from a myriad of mental and physical illnesses. It appears to be beneficial across ages, from children, to adolescents, to the elderly. And it appears to be beneficial across genders, personalities, race, and ethnicity. The breadth and depth of benefits is unprecedented. There is no other treatment or practice that has been shown to come anyway near the range of mindfulness’ positive benefits.

 

Meditation and yoga training have been shown to be effective for a large array of medical and psychiatric conditions, either stand-alone or in combination with more traditional therapies. Meditation and yoga appear to improve the individual’s ability to cope with stress and stress is the source of or aggravates many mental disorders. There are a number of ways that meditation and yoga practices produce these benefits, including changes to the brain and physiology. It is useful to review and summarize what has been discovered regarding how meditation and yoga practices improve mental disorders.

 

In today’s Research News article “Role of Yoga and Meditation as Complimentary Therapeutic Regime for Stress-Related Neuropsychiatric Disorders: Utilization of Brain Waves Activity as Novel Tool.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7545749/ ) Kaushik and colleagues review and summarize the published research on the effectiveness of meditation and yoga for the treatment of neuropsychiatric disorders.

 

They report that the published research finds that stress is highly related to anxiety and depression and that meditation and yoga practices, including breathing exercises and postures, significantly reduce perceived stress, anxiety, and depression. They further report that meditation and yoga may produce these improvements by increasing brain activity particularly in the frontal regions of the brain. They also report that meditation and yoga produce very few if any deleterious side effects.

 

Previous research has conclusively demonstrated that mindfulness practices in general are safe and effective in altering the electrical activity of the brain and reducing perceived stress, anxiety, and depression. It can be speculated that meditation and yoga reduce the responses to stress by altering brain activity and this, in turn, produces improvements in anxiety and depression. It remains for future research to investigate this model. Regardless, the employment of meditation and yoga practices for neuropsychiatric conditions has been shown to be safe and effective alternative treatments for the relief of the suffering of these patients.

 

So, improve stress-related neuropsychiatric disorders with yoga and mindfulness.

 

“mindfulness has become a household word, and the psychiatric and psychological literature abound with publications implementing mindfulness as a treatment or self-help tool for everything that ails you.” – John J. Miller

Abstract

During recent decades, stress-related neuropsychiatric disorders such as anxiety, depression, chronic tension headache, and migraine have established their stronghold in the lives of a vast number of people worldwide. In order to address this global phenomenon, intensive studies have been carried out leading to the advancement of drugs like anti-depressants, anxiolytics, and analgesics which although help in combating the symptoms of such disorders but also create long-term side effects. Thus, as an alternative to such clinical practices, various complementary therapies such as yoga and meditation have been proved to be effective in alleviating the causes and symptoms of different neuropsychiatric disorders. The role of altered brain waves in this context has been recognized and needs to be pursued at the highest level. Thus, the current study provides a review focused on describing the effects of yoga and meditation on anxiety and depression as well as exploring brain waves as a tool for assessing the potential of these complementary therapies for such disorders.

Meditation on Different States of Consciousness Produces Different Brain Activity

Meditation on Different States of Consciousness Produces Different Brain Activity

 

By John M. de Castro, Ph.D.

 

“Meditation is just self-directed neuroplasticity. In other words, you are directing the change of your brain by inwardly and consciously directing attention in a particular way. You’re using the mind to change the brain, like a child crafting a Playdough structure.” – Liam McClintock

 

Mindfulness training has been shown to improve health and well-being. It has also been found to be effective for a large array of medical and psychiatric conditions, either stand-alone or in combination with more traditional therapies. How exactly mindfulness practices produce their benefits is unknown. It is known that meditation practice alters states of consciousness and alters brain activity.

 

It is possible to investigate the relationships between consciousness and brain activity. One way is to measure changes in the electroencephalogram (EEG), the rhythmic electrical activity that can be recorded from the scalp. The recorded activity can be separated into frequency bands. Delta activity consists of oscillations in the 0.5-3 cycles per second band. Theta activity in the EEG consists of oscillations in the 4-8 cycles per second band. Alpha activity consists of oscillations in the 8-12 cycles per second band. Beta activity consists of oscillations in the 15-25 cycles per second band while Gamma activity occurs in the 35-45 cycles per second band. Changes in these brain activities can be compared during different forms of meditation with different conscious content.

 

In today’s Research News article “Large effects of brief meditation intervention on EEG spectra in meditation novices.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7649620/ ) Stapleton and colleagues recruited healthy meditation-naïve adults and had them attend a 3-day meditation training workshop where seated meditation to music was practiced 3 times per day. The participants were instructed to focus on different states (emotions, gratitude, surrendering, emotions, future events, oneness, energy, future intentions, and moving energy) during the meditations. During before, during, and after each meditation brain activity was recorded with an electroencephalogram (EEG).

 

They found that from the baseline to the end of the meditations there was a significant global increase in both Theta (4-8 hz.) and Gamma (35-45 hz.) rhythms in the EEG. These activities normally occur during information processing in the brain. They also found that different meditations produced different patterns of EEG activity. Delta activity was increased to the greatest extent by meditations on gratitude, elevated emotions, and energy. Theta activity was increased to the greatest extent by meditations on gratitude, elevated emotions, and future intention. Alpha activity was increased to the greatest extent by meditations on gratitude, oneness, and future intention. Beta activity was increased to the greatest extent by meditations on gratitude, future events, elevated emotions, and future intention. Finally, Gamma activity was increased to the greatest extent by meditations on gratitude, energy, and future intention.

 

These results suggest that different conscious content during meditation is reflected in differences in the activity of the brain in novice meditators. These understandings may be useful in identifying conscious content in real time during meditation. But these results need to be replicated in experienced meditators.

 

So, meditation on different states of consciousness produces different brain activity.

 

“mindfulness . . . has come to describe a meditation-based practice whose aim is to increase one’s sense of being in the present, but it has also been used to describe a nonmeditative state in which subjects set aside their mental distractions to pay greater attention to the here and now.” – Alvin Powell

Abstract

This study investigated the impact of a brief meditation workshop on a sample of 223 novice meditators. Participants attended a three-day workshop comprising daily guided seated meditation sessions using music without vocals that focused on various emotional states and intentions (open focus). Based on the theory of integrative consciousness, it was hypothesized that altered states of consciousness would be experienced by participants during the meditation intervention as assessed using electroencephalogram (EEG). Brainwave power bands patterns were measured throughout the meditation training workshop, producing a total of 5616 EEG scans. Changes in conscious states were analysed using pre-meditation and post-meditation session measures of delta through to gamma oscillations. Results suggested the meditation intervention had large varying effects on EEG spectra (up to 50 % increase and 24 % decrease), and the speed of change from pre-meditation to post-meditation state of the EEG co-spectra was significant (with 0.76 probability of entering end-meditation state within the first minute). There was a main 5 % decrease in delta power (95 % HDI = [−0.07, −0.03]); a global increase in theta power of 29 % (95 % HDI = [0.27, 0.33]); a global increase of 16 % (95 % HDI = [0.13, 0.19]) in alpha power; a main effect of condition, with global beta power increasing by 17 % (95 % HDI = [0.15, 0.19]); and an 11 % increase (95 % HDI = [0.08, 0.14]) in gamma power from pre-meditation to end-meditation. Findings provided preliminary support for brief meditation in altering states of consciousness in novice meditators. Future clinical examination of meditation was recommended as an intervention for mental health conditions particularly associated with hippocampal impairments.

Improve Glucose and Lipid Metabolism with Tai Chi

Improve Glucose and Lipid Metabolism with Tai Chi

 

By John M. de Castro, Ph.D.

 

“Tai Chi exercises can improve blood glucose levels and improve the control of type 2 diabetes and immune system response.” – Anna McKenney

 

Diet and exercise are the typical recommendation to improve glucose and lipid metabolism for the treatment and prevention of a number of metabolic disorders. Alternatives to classical exercise programs are Tai and Qigong practices. They have been practiced for thousands of years with benefits for health and longevity. Tai Chi training is designed to enhance function and regulate the activities of the body through regulated breathing, mindful concentration, and gentle movements.

 

Recently the effects of Tai Chi practice been scrutinized with empirical research. It has been found to be effective for an array of physical and psychological issues. It appears to strengthen the immune system, reduce inflammation, increase the number of cancer killing cells in the bloodstream and improve cardiovascular function. In addition, they appear to be effective in improving blood glucose and lipid metabolism. Because Tai Chi is not strenuous, involving slow gentle movements, and is safe, having no appreciable side effects, it is appropriate for all ages including the elderly and for individuals with illnesses that limit their activities or range of motion. But most studies of Tai Chi benefits have employed lengthy practices. The acute, immediate, effects of a session of Tai Chi have not been well investigated.

 

In today’s Research News article “Effect of a Single Session of Tai Chi Chuan Practice on Glucose and Lipid Metabolism and Related Hormones.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7460509/ ) Lu and colleagues recruited healthy adults over 50 years of age who were Tai Chi practitioners and a group of non-practitioners who were equivalent in age, gender, and body size. The Tai Chi group performed one 40-minute Tai Chi practice while the control group rested for 40 minutes. They obtained blood samples from both groups before and after their sessions and measured them for total cholesterol, blood glucose, insulin, insulin resistance, insulin sensitivity, and endothelin-1 (ET-1, a vasoconstrictor).

 

They found that at baseline, before practice, the Tai Chi group in comparison to the control group at rest had significantly lower levels of total cholesterol, insulin, insulin resistance, while insulin sensitivity was significantly higher. In comparison to the control group the Tai Chi group had a significantly greater percentage increases from baseline in blood glucose, insulin, and insulin resistance and a significantly larger percentage decreases in total cholesterol, HDL cholesterol, insulin sensitivity, and endothelin-1 (ET-1).

 

These are interesting results that must be tempered with the understanding that the control condition was not active. So, the changes seen after Tai Chi practice may have been due to exercise effects rather than performing Tai Chi itself. Indeed, the results on the immediate acute effects of Tai Chi practice on glucose and lipid metabolism are complicated and difficult to interpret. This may be due to the lack of an active control, comparison, condition, revealing the effects of activity vs. rest rather than effects specific to Tai Chi.

 

But the baseline results are not contaminated and they suggest that the practice of Tai Chi produces a general improvement in glucose and fat metabolism that is present even without immediate practice. This suggests that Tai Chi practice improves the overall physiological health of the practitioners. This would lead to lower likelihood of diabetes or cardiovascular disease and improvements in the diseases if present. Indeed Tai Chi practice has been found to be beneficial, improving symptoms, for people with diabetes and also cardiovascular disease.

 

So, improve glucose and lipid metabolism with Tai Chi.

 

“Diet and exercise are the cornerstone of diabetes management. People with diabetes who exercise regularly have better control over their blood glucose levels and fewer complications such as heart disease and stroke. Many people, however, are unable to keep up with their regular exercise because they either don’t enjoy it, or have a problem finding time to exercise. Tai chi offers a major advantage: It’s enjoyable, and to many, it’s almost addictive.” – Paul Lam

Abstract

Background: To examine the effect of Tai Chi Chuan (TCC) practice on glucose and lipid metabolism and related hormones in TCC practitioners. Methods: Twenty-one TCC practitioners and nineteen healthy controls were included in this study. Classical Yang’s TCC was practiced by the TCC practitioners. The percentage changes in serum total cholesterol (TC), high-density lipoprotein-cholesterol (HDL-C), serum glucose (SG), serum insulin, serum insulin level, homeostatic model assessment of insulin resistance (HOMA-IR), log(HOMA-IR), quantitative insulin sensitivity check index (QUICKI), and serum endothelin-1 (ET-1) before and 30 min after resting or TCC practice were compared between healthy controls and TCC practitioners. Results: Before TCC or resting, the serum insulin level, HOMA-IR, and log(HOMA-IR) of the TCC practitioners were significantly lower than those of healthy subjects, whereas the QUICKI of the TCC practitioners was significantly higher than that of healthy subjects. Thirty min after TCC practice, the %TC, %HDL-C, %QUICKI, and %ET-1 were all significantly decreased, whereas the %SG, %serum insulin, and %HOMA-IR were significantly increased in the TCC group as compared to the control group 30 min after resting. Conclusions: The serum glucose, insulin level and insulin resistance were enhanced, whereas the cholesterol, HDL-C and ET-1 levels were reduced 30 min after TCC practice. The mechanism underlying these effects of TCC 30 min after TCC is not clear yet.

Mind-Body Skills Training Improves College Student Mental Health and Well-Being

 

By John M. de Castro, Ph.D.

 

“By focusing on and controlling our breath, we can change how we think and feel. We can use the breath as a means of changing our emotional state and managing stress.” —Tommy Rosen

 

There is an accumulating volume of research findings to demonstrate that Mind-body practices have highly beneficial effects on the health and well-being of humans. These include meditation, yoga, tai chi, qigong, biofeedback, progressive muscle relaxation, guided imagery, hypnosis, and deep breathing exercises. Because of their proven benefits the application of these practices to relieving human suffering has skyrocketed.

 

There is a lot of pressure on college students to excel. This stress might in fact be counterproductive as the increased pressure can actually lead to stress and anxiety which can impede the student’s physical and mental health, well-being, and school performance. Mindfulness training has been shown through extensive research to be effective in improving physical and psychological health. Indeed, these practices have been found to improve psychological health in college students. So, it would be expected that training in mind-body practices would improve the psychological health of college students.

 

In today’s Research News article “Impact of a University-Wide Interdisciplinary Mind-Body Skills Program on Student Mental and Emotional Well-Being.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7686595/ ) Novak and colleagues recruited college students who were enrolled to take a mind-body skills program and an equivalent group of control college students. The program consisted of 9-weeks of once a week for 2 hours training and discussion of “mindfulness, guided imagery, autogenic training, biofeedback, and breathing techniques, as well as art, music, and movement practices” in groups of 10. The students were instructed to practice daily at home for 20 minutes. They were measured before and after training for perceived stress, positive and negative emotions, resilience, depression, anxiety, fatigue, sleep disturbance, mindfulness, interpersonal reactivity, and burnout. Subsets of each group were remeasured one year after the completion of the study. There were no significant differences in these measures between the groups at baseline.

 

They found that in comparison to the baseline and the control group, the students who received mind-body skills training had significant decreases in perceived stress, negative affect, depression, anxiety, sleep disturbance, and burnout and significant increases in positive emotions, resilience, mindfulness, empathic concern, and perspective taking. In addition, the higher the levels of mindfulness the lower the levels of perceived stress, negative emotions and depersonalization and the higher the levels of positive emotions, resilience, and perspective taking. Unfortunately, these improvements, except for mindfulness, disappeared by the one year follow up.

 

The present study did not have an active control condition. So, it is possible that confounding factors such as participant expectancy, experimenter bias, attention effects etc. may have been responsible for the results. But in prior controlled research it has been demonstrated that mindfulness training produces decreases in perceived stress, negative emotions, depression, anxiety, sleep disturbance, and burnout and significant increases in positive emotions, resilience, and empathic concern. So, it is likely that the benefits observed in the present study were due to the mind-body skills training.

 

These results then suggest that mind-body skills training produces marked improvements in the psychological health and well-being of college students. But the improvements were not lasting. This may signal the need for better training protocols or periodic booster session to maintain the benefits. Given the great academic stress, pressure, and social stresses of college life, the students were much better off for taking the mind-body skills training program. It was not measured but these benefits would predict increased academic performance and improved well-being in these students.

 

So, mind-body skills training improves college student mental health and well-being.

Abstract

Background

Positive effects of mind-body skills programs on participant well-being have been reported in health professions students. The success seen with medical students at this university led to great interest in expanding the mind-body skills program so students in other disciplines could benefit from the program.

Objective

The purpose of this study was to assess the effects of a 9-week mind-body skills program on the mental and emotional well-being of multidisciplinary students compared to controls. We also sought to determine if the program’s effects were sustained at 1-year follow-up.

Methods

A cross-sectional pre-post survey was administered online via SurveyMonkey to participants of a 9-week mind-body skills program and a control group of students from 7 colleges at a public university from 2017–2019. Students were assessed on validated measures of stress, positive/negative affect, resilience, depression, anxiety, fatigue, sleep disturbance, mindfulness, empathy, and burnout. Scores were analyzed between-groups and within-groups using bivariate and multivariate analyses. A 1-year follow-up was completed on a subset of participants and controls.

Results

279 participants and 247 controls completed the pre-survey and post-survey (79% response rate; 71% female, 68% white, mean age = 25 years). Participants showed significant decreases in stress, negative affect, depression, anxiety, sleep disturbance, and burnout, while positive affect, resilience, mindfulness, and empathy increased significantly (P < .05). Only sleep disturbance showed a significant decrease in the control group. Follow-up in a subset of participants showed that only mindfulness remained elevated at 1-year (P < .05), whereas the significant changes in other well-being measures were not sustained.

Conclusion

Participation in a 9-week mind-body skills program led to significant improvement in indicators of well-being in multidisciplinary students. A pilot 1-year follow-up suggests that effects are only sustained for mindfulness, but not other parameters. Future programming should focus on implementing mind-body skills booster sessions to help sustain the well-being benefits.
