Breathing-Focused Yoga Practices Produce Greater Benefits for College Students than Meditative-Focused Practices

Breathing-Focused Yoga Practices Produce Greater Benefits for College Students than Meditative-Focused Practices

 

By John M. de Castro, Ph.D.

 

“Want to manage your anger so you don’t feel you’re always on the verge of blowing up? Want to feel less stressed and juggle all the things going on in your life? Need to focus better in class or while you do your homework? Yoga poses can help. But meditation and breathing really round out those benefits.” – Mary L. Gavin

 

Yoga training has been shown to improve health and well-being. It has also been found to be effective for a large array of medical and psychiatric conditions, either stand-alone or in combination with more traditional therapies. There are a wide variety of different yoga training techniques. Many varieties employ breath-focused practices while many others employ meditative-focused practices. Although the benefits of yoga practices in general are well studied there is little scientific research comparing breathing-focused versus meditative-focused yoga.

 

In today’s Research News article “Comparing the Psychological Effects of Meditation- and Breathing-Focused Yoga Practice in Undergraduate Students.” (See summary below or view the full text of the study at: https://www.frontiersin.org/articles/10.3389/fpsyg.2020.560152/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_1490157_69_Psycho_20201124_arts_A ) Qi and colleagues recruited college students with no yoga experience and randomly assigned them to a once a week for 80 minutes 12-week program of either breath-focused yoga or meditation-focused yoga. During each Hatha yoga class the students received either 10 minutes of meditation practice or breathing practice. They were measured before and after the program for work intention, mindfulness, and perceived stress.

 

They found that both before and after yoga training the higher the participants’ levels of mindfulness the lower their levels of perceived stress. They further found that in comparison to baseline and the other yoga group, the breath-focused yoga group had significantly higher levels of perceived stress and mindfulness while the meditation-focused yoga group had significantly lower work intention.

 

These results are interesting and document the previously reported linkage between mindfulness and lower stress levels. But they go further in demonstrating that breath-focus is an important component of yoga practice for the improvement of mindfulness and the lowering of perceived stress. This suggests that breathing practice should be emphasized in yoga instruction. These results also suggest that yoga practice may be beneficial for college students who are routinely found to have high stress levels, reducing their stress and thereby allowing them to perform their best in their studies.

 

So, breathing-focused yoga practices produce greater benefits for college students than meditative-focused practices.

 

Mindful yoga (or the integration of yoga and mindfulness meditation techniques) provides a healthy and safe environment for individuals to practice “being with” uncomfortable emotional and physical experiences, and to eventually reunite with and fully inhabit their bodies.” – Melissa Mercedes

ABSTRACT

Objectives: The present study aimed to compare the psychological effects of meditation- and breathing-focused yoga practice in undergraduate students.

Methods: A 12-weeks yoga intervention was conducted among a group of undergraduate students enrolled in four yoga classes at an academically prestigious university in Beijing, China. Four classes were randomized to meditation-focused yoga or breathing-focused yoga. A total of 86 participants finished surveys before and after the 12-weeks intervention, measuring work intention, mindfulness, and perceived stress. The repeated-measure multivariate analysis of covariance (MANCOVA) followed by univariate analyses were conducted to examine the differences in work intention, mindfulness, and stress between the two yoga intervention groups over the semester, after controlling for age and gender.

Results: The repeated-measure MANCOVA revealed significant group differences with a median effect size [Wilks’ lambda, Λ = 0.90, F(3, 80) = 3.10, p = 0.031, η2 = 0.104]. Subsequent univariate analyses showed that students in the breathing-focused yoga group had significant higher work intentions [F(1, 82) = 5.22; p = 0.025; η2p = 0.060] and mindfulness [F(1, 82) = 6.33; p = 0.014; η2p = 0.072] but marginally lower stress [F(1, 82) = 4.20; p = 0.044; η2p = 0.049] than students in the meditation-focused yoga group.

Conclusion: Yoga practice with a focus on breathing is more effective than that with a focus on meditation for undergraduates to retain energy for work, keep attention and awareness, and reduce stress.

Improve Psychological Health and Quality of Life of Older Adults with Meditative Movement Practices.

Improve Psychological Health and Quality of Life of Older Adults with Meditative Movement Practices.

 

By John M. de Castro, Ph.D.

 

Mindful techniques can help older adults feel a sense of connection to their body. This can be critical for creating optimal health, even as they manage the ongoing changes in their body.” – Karen Fabian

 

The aging process involves a systematic progressive decline in every system in the body, the brain included. This includes our cognitive (mental) abilities which decline with age including impairments in memory, attention, and problem-solving ability. It is inevitable and cannot be avoided. Research has found that mindfulness practices reduce the deterioration of the brain that occurs with aging restraining the loss of neural tissue. Indeed, the brains of practitioners of meditation and yoga have been found to degenerate less with aging than non-practitioners. Tai Chi and Qigong have also been shown to be beneficial in slowing or delaying physical and mental decline with aging. The research findings are accumulating suggesting that a summarization of what has been learned is called for.

 

In today’s Research News article “Effects of Mind-Body Interventions Involving Meditative Movements on Quality of Life, Depressive Symptoms, Fear of Falling and Sleep Quality in Older Adults: A Systematic Review with Meta-Analysis.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7559727/ ) Weber and colleagues  review, summarize, and perform a meta-analysis of the published randomized controlled studies (RCTs) of the effectiveness of the mind-body practices of Yoga, Tai Chi. Qigong, and Pilates to improve the psychological health and quality of life in the elderly (aged 60 and over). They identified 37 published RCTs, 21 of which employed Tai Chi. 5 Qigong, 10 Yoga, and 3 Pilates.

 

They separated studies employing Tai Chi and Qigong from those employing Yoga and Pilates. They report that the published studies found that all of the meditative movement practices significantly improved the quality of life, physical functioning, and sleep quality and reduced the fear of falling of older adults with small effect sizes. Only the Tai Chi and Qigong practices produced significant improvements in psychological functioning and social functioning while only the Yoga and Pilates produced significant improvements in depression. For Tai Chi and Qigong, they further report that practice occurring 3 or more times per week resulted in larger improvements in quality of life and depression than those with less than 3 practices per week.

 

These findings suggest that meditative movement practices have wide ranging benefits, albeit with relatively small effect sizes, on the physical, psychological, and social functioning of older adults and improve their overall quality of life. These are important benefits for the elderly helping to slow the progressive decline seen with aging. These practices when properly performed and supervised have very few adverse effects. Hence, they should be recommended for aging individuals as safe and effective practices to slow the progressive decline and improve their overall well-being.

 

So, improve psychological health and quality of life of older adults with meditative movement practices.

 

When you age mindfully, you are fully aware and accepting of the challenges that come with the aging process, but you’re also aware of—and seizing—the opportunities that come with being blessed with what I call your ‘longevity bonus,’” – Andrea Brandt.

Effects of Mind-Body Interventions Involving Meditative Movements on Quality of Life, Depressive Symptoms, Fear of Falling and Sleep Quality in Older Adults: A Systematic Review with Meta-Analysis. International journal of environmental research and public health, 17(18), 6556. https://doi.org/10.3390/ijerph17186556

 

Abstract

Background: The aim of the present systematic meta-analytical review was to quantify the effects of different mind–body interventions (MBI) involving meditative movements on relevant psychological health outcomes (i.e., quality of life (QoL), depressive symptoms, fear of falling (FoF) and sleep quality) in older adults without mental disorders. Methods: A structured literature search was conducted in five databases (Ovid, PsycINFO, PubMed, SPORTDiscus, Web of Science). Inclusion criteria were: (i) the study was a (cluster) randomized controlled trial, (ii) the subjects were aged ≥59 years without mental illnesses, (iii) an intervention arm performing MBI compared to a non-exercise control group (e.g., wait-list or usual care), (iv) psychological health outcomes related to QoL, depressive symptoms, FoF or sleep quality were assessed and (v) a PEDro score of ≥5. The interventions of the included studies were sub-grouped into Tai Chi/Qigong (TCQ) and Yoga/Pilates (YP). Statistical analyses were conducted using a random-effects inverse-variance model. Results: Thirty-seven randomized controlled trials (RCTs) (comprising 3224 participants) were included. Small to moderate-but-significant overall effect sizes favoring experimental groups (Hedges’ g: 0.25 to 0.71) compared to non-exercise control groups were observed in all outcomes (all p values ≤ 0.007), apart from one subdomain of quality of life (i.e., social functioning, p = 0.15). Interestingly, a significant larger effect on QoL and depressive symptoms with increasing training frequency was found for TCQ (p = 0.03; p = 0.004). Conclusions: MBI involving meditative movements may serve as a promising opportunity to improve psychological health domains such as QoL, depressive symptoms, FoF and sleep quality in older adults. Hence, these forms of exercise may represent potential preventive measures regarding the increase of late-life mental disorders, which need to be further confirmed by future research.

Reduce Fatigue and Improve Quality of Life of Breast Cancer Survivors with Yoga

Reduce Fatigue and Improve Quality of Life of Breast Cancer Survivors with Yoga

 

By John M. de Castro, Ph.D.

 

“For women with breast cancer, research shows those who practice yoga may also have less stress and fatigue, and better quality of life.” – Stacie Simon

 

Because of great advances in treatment, many patients today are surviving cancer. But cancer survivors frequently suffer from anxiety, depression, mood disturbance, post-traumatic stress disorder (PTSD), sleep disturbance, fatigue, sexual dysfunction, loss of personal control, impaired quality of life, and psychiatric symptoms which have been found to persist even ten years after remission. Also, cancer survivors can have to deal with a heightened fear of reoccurrence. So, safe and effective treatments for the symptoms in cancer and the physical and psychological effects of the treatments are needed.

 

Mindfulness training has been shown to help with general cancer recovery. Mindfulness practices have been shown to improve the residual symptoms in cancer survivors.  Yoga is both an exercise and a mindfulness practice that has also been shown to be helpful with the residual symptoms in cancer survivors, the psychological and physical ability to deal with cancer treatment and improves sleep. The research on yoga practice as a treatment for patients recovering from breast cancer has been accumulating. It is thus reasonable to take a step back and summarize what has been learned.

 

In today’s Research News article “The Effect of Yoga Interventions on Cancer-Related Fatigue and Quality of Life for Women with Breast Cancer: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7580184/ ) O’Neill and colleagues review, summarize, and perform a meta-analysis of published randomized controlled trials of the effects of yoga practice on the fatigue and quality of life of breast cancer survivors. They identified 24 published randomized controlled trials.

 

They report that the published trials revealed that yoga practice produced significant reductions in cancer related fatigue and increases in the women’s quality of life. This was true overall and for the 18 trials with a passive control group such as a wait-list control, but not for the 6 trials with an active control group, such as physical exercise or supportive therapy. Hence, yoga practice appears to be beneficial for breast cancer survivors reducing fatigue and improving quality of life. But the benefits are comparable to those produced by other exercises or therapies.

 

So, reduce fatigue and improve quality of life of breast cancer survivors with yoga.

 

A targeted yoga intervention led to significant improvements in fatigue and vigor among breast cancer survivors with persistent fatigue symptoms.” – Julienne Bower

Abstract

Background:

Women with breast cancer (BC) are living longer with debilitating side effects such as cancer-related fatigue (CRF) that affect overall well-being. Yoga promotes health, well-being and may be beneficial in reducing CRF. Although there have been previous systematic reviews and meta-analyses, the effects of yoga on CRF and quality of life (QOL) remain unclear, particularly in comparison with other types of physical activity (PA). Our objective is to carry out a systematic review and meta-analysis of the effects of yoga on CRF and QOL in women with BC.

Methods:

Electronic databases were searched (MEDLINE, Embase Classic+Embase and EMB Reviews, Cochrane Central CT) from inception to May 2018. Randomized controlled trials were included if they were full text, in English, included a yoga intervention, a comparator (including non-PA usual care or alternate PA intervention), and reported on CRF or QOL. Effects of yoga were pooled using standardized mean difference (SMD) via a random effects model.

Results:

Of the 2468 records retrieved, 24 trials were included; 18 studies compared yoga to a non-PA comparator and 6 to a PA comparator. Yoga demonstrated statistically significant improvements in CRF over non-PA (SMD −0.30 [−0.51; −0.08]) but not PA (SMD −0.17 [−0.50; 0.17]) comparators. Additionally, yoga demonstrated statistically significant improvements in QOL over non-PA (SMD −0.27 [−0.46; −0.07]) but not PA (SMD 0.04 [−0.22; +0.31]) comparators.

Discussion:

This meta-analysis found that yoga provides small to medium improvements in CRF and QOL compared to non-PA, but not in comparison to other PA interventions.

Reduce Anxiety in Women Undergoing Fertility Treatment with Yoga

Reduce Anxiety in Women Undergoing Fertility Treatment with Yoga

 

By John M. de Castro, Ph.D.

 

“yoga is a relaxing activity. And there are some researched benefits regarding yoga, infertility, and the exercise’s ability to help couples release mental stress and physical tension.” – Ashley Marcin

 

Infertility is primarily a medical condition due to physiological problems. It is quite common. It is estimated that in the U.S. 6.7 million women, about 10% of the population of women 15-44, have an impaired ability to get pregnant or carry a baby to term and about 6% are infertile. Infertility can be more than just a medical issue. It can be an emotional crisis for many couples, especially for the women. Couples attending a fertility clinic reported that infertility was the most upsetting experience of their lives.

 

Women with infertility reported feeling as anxious or depressed as those diagnosed with cancer, hypertension, or recovering from a heart attack. In addition, infertility can markedly impact the couple’s relationship, straining their emotional connection and interactions and the prescribed treatments can take the spontaneity and joy from lovemaking making it strained and mechanical. The stress of infertility and engaging in infertility treatments may exacerbate the problem. Since mindfulness training has been shown to reduce depressionanxiety, and stress it is reasonable to believe that mind-body training may be helpful in reducing the distress in women with fertility issues. Yoga is both a mindfulness practice and an exercise that has been studied for its benefits for women undergoing fertility treatments.

 

In today’s Research News article “Effect of Yoga on Psychological Distress among Women Receiving Treatment for Infertility.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7336944/ ) Dumbala and colleagues review and summarize the published research studies on the effectiveness of yoga practice for the relief of the psychological symptoms produced by infertility.

 

They identified 3 published research studies all of which found that yoga practice reduced anxiety levels in women being treated for infertility. They also report that the research found that yoga improved the quality of life and reduced depression levels in these women. It has previously been shown that yoga practice reduces anxiety and depression and improves quality of life in a wide variety of healthy and ill individuals. The present review demonstrates that these benefits also extend to women being treated for infertility. The review and the included studies did not study whether yoga increased the likelihood of conception. But improving the psychological state of these women could only be helpful.

 

So, reduce anxiety in women undergoing fertility treatment with yoga.

 

Yoga also offers a safe space for us to work through challenge and build resilience. It allows us to sit with discomfort by challenging us to hold a pose longer than we’d like, knowing it’s temporary. This is a valuable skill, not only for the fertility process, but it also helps prepare us for birth and parenthood (which combine discomfort, joy, and everything in between!)” – Kate Potvin

Abstract

Background:

Infertility among women has been associated with significant psychological distress, anxiety, and depression. yoga therapy has been found to be useful in the management of anxiety, depression and psychological distress.

Aim:

To review studies on the effectiveness of yoga in reducing psychological distress and improving clinical outcomes among women receiving treatment for infertility.

Methodology:

PubMed, ScienceDirect, and Google Scholar databases were searched for studies using the following inclusion criteria: studies published in English, those published between 2000 and 2018, published in peer-reviewed journals, and those with Yoga as an intervention. Review articles, studies without any yoga interventions for infertility, and male infertility were excluded. The keywords included for the literature search were: Yoga, Mindfulness, Relaxation technique, Stress, Distress, Anxiety, Infertility, In Vitro Fertilization (IVF), and Assisted Reproductive Technology (ART).

Results:

Three studies satisfied the selection criteria. Two studies involved Hatha yoga intervention and one study used structured yoga program. The variables assessed in these studies were: (1) anxiety, (2) depression, (3) emotional distress, and (4) fertility-related quality of life. All the studies reported an improvement in the anxiety scores after yoga intervention.

Conclusion:

Yoga therapy may be potentially useful in improving anxiety scores among women suffering from infertility. More studies are needed in this area to establish role of yoga as an adjuvant during the treatment of infertility.

Manage Symptoms in Cancer Survivors with Yoga

Manage Symptoms in Cancer Survivors with Yoga

 

By John M. de Castro, Ph.D.

 

“when it’s used alongside conventional medical treatment, yoga may help relieve some of the symptoms linked to cancer.” – American Cancer Society

 

Because of great advances in treatment, many patients today are surviving cancer. But cancer survivors frequently suffer from anxiety, depression, mood disturbance, post-traumatic stress disorder (PTSD), sleep disturbance, fatigue, sexual dysfunction, loss of personal control, impaired quality of life, and psychiatric symptoms which have been found to persist even ten years after remission. Also, cancer survivors can have to deal with a heightened fear of reoccurrence. This is particularly true with metastatic cancer. So, safe and effective treatments for the symptoms in cancer and the physical and psychological effects of the treatments are needed.

 

Mindfulness training has been shown to help with general cancer recovery . Yoga is both an exercise and a mindfulness practice that has also been shown to be helpful with the residual symptoms in cancer survivors, the psychological and physical ability to deal with cancer treatment and improves sleep. So, it’s reasonable to review what has been learned about the benefits of yoga practice to improve the residual symptoms of patients who have survived cancer.

 

In today’s Research News article “Yoga for symptom management in oncology: A review of the evidence base and future directions for research.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6541520/ ) Danhauer and colleagues review and summarize the published randomized controlled studies of the effectiveness of yoga practice for the treatment of the symptoms of cancer survivors. They identified 29 published randomized controlled trials, 13 conducted during treatment, 12 after treatment, and 4 both before and after.

 

They report that the published research found that yoga during treatment for cancer significantly improved the patient’s quality of life, including physical, emotional social, and cognitive quality of life. They also report that yoga significantly reduced fatigue, distress, perceived stress, and biomarkers of stress and inflammation. Yoga after treatment completion was found to significantly reduce fatigue and sleep disturbance and improve quality of life. There were no serious adverse events resulting from yoga practice reported.

 

The published research then suggests that yoga practice is a safe and effective treatment both during and after cancer treatment for the relief of the patients’ residual physical and psychological symptoms. Yoga practice is a complex of practices that includes postures, breath control, and meditation. It has not been clearly established which of these components or which combination of components are required for the benefits. So, conclusions cannot be made regarding mechanisms of action by which yoga produces its benefits. But it can be concluded that yoga practice is very beneficial for cancer sufferers.

 

So, manage symptoms in cancer survivors with yoga.

Abstract

As yoga is increasingly recognized as a complementary approach to cancer symptom management, patients/survivors and providers need to understand its potential benefits and limitations both during and after treatment. We reviewed randomized controlled trials (RCTs) of yoga conducted at these points in the cancer continuum (N=29; n=13 during treatment, n=12 post-treatment, n=4 with mixed samples). Findings both during and after treatment demonstrated efficacy of yoga to improve overall quality of life (QOL), with improvement in subdomains of QOL varying across studies. Fatigue was the most commonly measured outcome, and most RCTs conducted during or after cancer treatment reported improvements in fatigue. Results additionally suggest that yoga can improve stress/distress during treatment and post-treatment disturbances in sleep and cognition. A number of RCTs showed evidence that yoga may improve biomarkers of stress, inflammation, and immune function. Outcomes with limited or mixed findings (e.g., anxiety, depression, pain, cancer-specific symptoms such as lymphedema, positive psychological outcomes such as benefit-finding and life satisfaction) warrant further study. Important future directions for yoga research in oncology include: enrolling participants with cancer types other than breast, standardizing self-report assessments, increasing use of active control groups and objective measures, and addressing the heterogeneity of yoga interventions, which vary in type, key components (movement, meditation, breathing), dose, and delivery mode.

Reduce Heart Arrhythmia with Yoga

Reduce Heart Arrhythmia with Yoga

 

By John M. de Castro, Ph.D.

 

the practice of yoga is good for overall heart health, and especially beneficial for afib patients. Yoga can help reduce the number of episodes, lower blood pressure, and alleviate some of the anxiety and depression that may go along with having the condition.” – Midwest Health

 

Cardiovascular disease is the number one killer, claiming more lives than all forms of cancer combined. Lifestyle changes have proved to be quite effective in reducing the risk of cardiovascular disease. 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 cessationweight reduction and stress reduction. Yoga is a mindfulness practice that has been shown to improve physical well-being and cardiovascular health.

 

An arrhythmia is a problem with the rate or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slowly, or with an irregular rhythm. When a heart beats too fast, the condition is called tachycardia. When a heart beats too slowly, the condition is called bradycardia.” (NIH). Arrythmias if untreated could lead to heart failure, stroke, cardiac arrest and sudden infant death. So, it is very important to identify treatments for arrhythmias. Research on the ability of yoga practice to treat arrhythmias has been accumulating, So, it makes sense to step back and review what has been learned on the ability of yoga to treat heart arrhythmia.

 

In today’s Research News article “Impact of Yoga on Cardiac Autonomic Function and Arrhythmias.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7533135/ ) Akella and colleagues review and summarized the published research on the effects of yoga practice on heart arrhythmia and its symptoms.

 

They report that the published research studies found that practicing yoga reduces heart arrhythmias. It reduces resting blood pressure and heart rate in these patients and reduces atrial fibrillation, ventricular arrhythmia and syncope. They further report that the published research suggests that these benefits results from yoga practice producing an increase in vagal tone and a reduction in fluctuations in the autonomic nervous system.

 

The autonomic nervous system is responsible for controlling the physiology of the body including the cardiovascular system. The sympathetic division of the autonomic nervous system is the component that oversees activation, including increases in heart rate and blood pressure while the parasympathetic division, controlled through the vagus nerve, oversees relaxation including decreases in heart rate and blood pressure. The increase in vagal tone observed in the yoga practitioners indicates an increase in the parasympathetic, relaxation, responses. The reduction in fluctuation in the autonomic nervous system indicates that there is less variation over time in the physiological systems, fewer wild swings in heart rate and blood pressure. In this way, yoga practice appears to improve cardiovascular function and thereby reduce arrhythmias. Needless to say that this is very beneficial for the health and even survival of these patients.

 

So, reduce heart arrhythmia with yoga.

 

Yoga may improve quality of life in patients with paroxysmal AFib because it gives them a method to gain some self-control over their symptoms instead of feeling helpless,” – Maria Wahlström

Abstract

With the expanding integration of complementary and alternative medicine (CAM) practices in conjunction with modern medicine, yoga has quickly risen to being one of the most common CAM practices across the world. Despite widespread use of yoga, limited studies are available, particularly in the setting of dysrhythmia. Preliminary studies demonstrate promising results from integration of yoga as an adjunct to medical therapy for management of dysrhythmias. In this review, we discuss the role of autonomic nervous system in cardiac arrhythmia,interaction of yoga with autonomic tone and its subsequent impact on these disease states. The role of yoga in specific disease states, and potential future direction for studies assessing the role of yoga in dysrhythmia.

Improve Low Back Pain with Walking and Mind-Body Practices

Improve Low Back Pain with Walking and Mind-Body Practices

 

By John M. de Castro, Ph.D.

 

“Mindfulness training teaches us to be aware of, and accept, moment-to-moment physical sensations of discomfort, while letting go of our usual negative reactions. So instead of spending hours each day thinking about how much we hate our back pain, worrying about our prognosis, and seeking relief, we learn how to be with the pain — paying attention to how it actually feels at each moment and relaxing our tendency to tense up against it, while observing our worried or distressed thoughts and feelings coming and going.” – Ronald Siegel

 

Low Back Pain is the leading cause of disability worldwide and affects between 6% to 15% of the population. It is estimated, however, that 80% of the population will experience back pain sometime during their lives. There are varied treatments for low back pain including chiropractic care, acupuncture, biofeedback, physical therapy, cognitive behavioral therapy, massage, surgery, opiate pain killing drugs, steroid injections, and muscle relaxant drugs. These therapies are sometimes effective particularly for acute back pain. But, for chronic conditions the treatments are less effective and often require continuing treatment for years and opiate pain killers are dangerous and can lead to abuse, addiction, and fatal overdoses.

 

Obviously, there is a need for safe and effective treatments for low back pain that are low cost and don’t have troublesome side effects. Mindfulness practices are effective in treating pain and have been shown to be safe and effective in the management of low back painYoga practice has been shown to have a myriad of health benefits. These include relief of chronic painYoga practice has also been shown to be effective for the relief of chronic low-back pain.  Other mind-body  practices such as Tai Chi  improves spinal health and reduces pain. The evidence is accumulating, so, it would seem reasonable to summarize what has been learned regarding the ability of mind-body practices to treat chronic low back pain.

 

In today’s Research News article “Effectiveness of walking versus mind-body therapies in chronic low back pain: A systematic review and meta-analysis of recent randomized controlled trials.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7458239/ ) Nduwimana and colleagues reviewed, summarized, and performed a meta-analysis of the published randomized controlled trials comparing the effectiveness of m1nd-body practices and walking for the relief of chronic low back pain. They identified 31 published trials containing a total of 3193 participants.

 

They report that the published research found that both walking and m1nd-body practices were effective in significantly reducing low back pain. Of the m1nd-body practices, yoga was particularly effective not only reducing pain but also producing significant reductions in activity limitations resulting from low back pain. On the short-term (up to 3 months) yoga produced significant pain reductions while on the intermediate-term (3 to 6 months), walking produced significant pain reductions.

 

These results are important as low back pain is ubiquitous and produces not only discomfort but also limitations on the ability of patients to conduct their lives. So, its relief greatly reduces the suffering and improves the quality of life. The comparison of mind-body practices to walking is important as both are exercises and their relative effectiveness assessed. The results suggest that yoga practice has better short-term effectiveness while walking appears to be better for the intermediate term. This further suggests that future research should explore the effectiveness of the combination of mind-body practices and walking in the treatment of low back pain.

 

So, improve low back pain with walking and mind-body practices.

Abstract

Purpose:

Walking and mind-body therapies (MBTs) are commonly recommended to relieve pain and improve function in patients with chronic low back pain (CLBP). The purpose of this study was to compare the effectiveness of walking and MBTs in CLBP.

Methods:

We included randomized controlled trials (RCTs) comparing walking or MBTs to any other intervention or control in adults with CLBP. Studies were identified through PubMed, Cochrane Library, PsycINFO, Scopus, and ScienceDirect databases. The research was limited to studies published in English and French between January 2008 and December 2018. Two reviewers independently selected the studies, extracted data, and assessed studies quality using the Physiotherapy Evidence Database (PEDro) scale. Statistical analyses were performed under a random-effects model. We analyzed pain and activity limitation, with the calculation of standardized mean differences and 95% confidence intervals for the different treatment effects.

Results:

Thirty one randomized controlled trials involving 3193 participants were analyzed. Walking was as effective as control interventions in the short-term and slightly superior in the intermediate term with respect to pain (Standardized mean differences (SMD)  = –0.34; 95% CI, –0.65 to –0.03; P = .03) and activity limitation (SMD = –0.30; 95% CI, –0.50 to –0.10; P = .003). In contrast, yoga was more effective than control interventions in the short term in terms of pain (SMD = –1.47; 95% CI, –2.26 to –0.68; P = .0003) and activity limitation (SMD = –1.17; 95% CI, –1.80 to –0.55; P = .0002). Yoga was no longer superior to the control interventions for pain at the 6-month follow-up.

Conclusion:

MBTs, especially yoga, seem to be more effective in the short term, and walking seems to be more effective in the intermediate term, for the relief of pain and activity limitation in patients with CLBP. A combination of walking and MBTs fits the biopsychosocial model and might be valuable therapy for CLBP throughout follow-up due to combined effects.

Reduce the Symptoms of Schizophrenia with Mind-Body Practices

Reduce the Symptoms of Schizophrenia with Mind-Body Practices

 

By John M. de Castro, Ph.D.

 

“Research shows that some mindfulness-based interventions for psychotic symptoms can afford people a greater acceptance and insight into their experiences. They can also reduce the symptoms of anxiety and depression which often accompany, and may exacerbate, psychotic disorders.” – Adrianna Mendrek

 

Schizophrenia is the most common form of psychosis. Its effects about 1% of the population worldwide. It appears to be highly heritable and involves changes in the brain. It is characterized by both positive and negative symptoms. Positive symptoms include hallucinations; seeing and, in some cases, feeling, smelling or tasting things that aren’t there, or delusions; unshakable beliefs that, when examined rationally, are obviously untrue. Negative symptoms include a reduced ability to function normally, neglect of personal hygiene, lack of emotion, blank facial expressions, speaking in a monotone, loss of interest in everyday activities, social withdrawal, an inability to experience pleasure, and a lack of insight into their symptoms. The symptoms of schizophrenia usually do not appear until late adolescence or early adulthood.

 

Schizophrenia is very difficult to treat with psychotherapy and is usually treated with antipsychotic drugs. These drugs, however, are not always effective, sometimes lose effectiveness, and can have some difficult side effects. Mindfulness training has been shown to be beneficial for a variety of mental health problems, including psychosis. Mindfulness has also been shown to associated with lower symptom severity of schizophrenia. Also, there is accumulating research that mindfulness and yoga practices may be beneficial for patients with major mental illnesses. Tai Chi and Qigong  practices have also been shown to improve the symptoms of schizophrenia. The evidence is accumulating. So, it makes sense to step back and summarize what has been learned about mind-body practices as treatments for schizophrenia.

 

In today’s Research News article “Effects of Mind-Body Exercises on Schizophrenia: A Systematic Review With Meta-Analysis.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7457019/ ) Wei and colleagues review, summarize and perform a meta-analysis of the published controlled research studies of the effectiveness of mind-body practices to improve the symptoms of schizophrenia. They included Tai Chi, Qigong, yoga, and other mindful movement practices. They identified 13 studies (11 randomized controlled trials) employing a total of 1159 patients with schizophrenia.

 

They report that the published studies found that mind-body practices produced significant improvements of both the positive and negative symptoms of schizophrenia and also depression. In addition, the greater the number of weekly mind-body sessions the greater the improvement in the positive symptoms and the greater the duration of the mind-body sessions the greater the improvements in the negative symptoms.

 

These results are impressive as schizophrenia is difficult to treat. But the results show that mind-body practices are safe and effective treatments that improve not only the positive and negative symptoms of schizophrenia but also the frequently co-occurring depression. There also appears to be a dose response effect such that the greater the frequency and duration of mind-body practices the greater the benefits. This suggests that mind-body practices should be recommended as a part of the treatment for schizophrenia.

 

So, reduce the symptoms of schizophrenia with mind-body practices.

Abstract

Background

Mind–body exercises (MBEs) have been widely accepted as a complementary therapy for the patients with low exercise tolerance. Currently, the number of experimental studies investigating the effect of MBEs for improving symptoms in people with schizophrenia is increasing. However, results are inconsistent.

Methods

We systematically reviewed and meta-analyzed the effects of mind–body exercises on schizophrenia. Seven electronic databases (Pubmed, Web of Science, PsycINFO, Embase, Cochrane Central Register of Controlled Trials [CENTRAL], CNKI and Wangfang) were screened through October 2019 and risks of bias of included studies were assessed in Review Manager 5.3.

Results

Meta-analysis on 13 studies with 1,159 patients showed moderately significant effects in favor of mind–body exercise intervention to improve positive symptoms (SMD = 0.31; 95% CI 0.01 to 0.60; p = 0.04), negative symptoms (SMD = 0.37; 95% CI 0.14 to 0.60; p = 0.002), and depression (SMD = 0.88; 95% CI 0.63 to 1.13; p<0.00001). Meta-regression analysis revealed that the improvement in positive symptoms was positively associated with the frequency of intervention (p = 0.04), while a marginally significant correlation was observed between the improved negative symptoms and duration of each session (p = 0.06).

Conclusions

This meta-analysis supports the therapeutic effects of MBEs to aid in the treatment of schizophrenia. Further studies need to incorporate rigorous design and large sample size to identify the optimal type and dose of mind–body exercise to inform clinical practices on MBEs’ recommendations for the management of schizophrenia symptoms.

Reduce Inflammatory Responses and Reduce Rheumatoid Arthritis Symptoms with Yoga

Reduce Inflammatory Responses and Reduce Rheumatoid Arthritis Symptoms with Yoga

 

By John M. de Castro, Ph.D.

 

“yoga practice significantly decreases the severity of physical and psychological symptoms in patients with active rheumatoid arthritis.” – Science Daily

 

Arthritis is a chronic disease that most commonly affects the joints. Depending on the type of arthritis, symptoms may include pain, stiffness, swelling, redness, and decreased range of motion. It affects an estimated 52.5 million adults in the United States. It is associated with aging as arthritis occurs in only 7% of adults ages 18–44, while 30% adults ages 45–64 are affected, and 50% of adults ages 65 or older. Due to complications associated with rheumatoid arthritis (RA), the lifespan for people with RA may be shortened by 10 years. This is due to a higher incidence of cardiovascular disease in rheumatoid arthritis (RA) patients, with the risk more than double that of non-RA individuals.

 

Obviously, there is a need to explore alternative treatments for rheumatoid arthritis. One possibility is contemplative practice. A variety of which have been shown to have major mental and physical benefits including a reduction in the inflammatory response and have been shown to improve arthritis. Indeed, yoga practice has been shown to be effective in treating arthritis. So, it makes sense to investigate the effects of yoga practice on the inflammatory response in patients with rheumatoid arthritis.

 

In today’s Research News article “Effect of an 8-Week Yoga-Based Lifestyle Intervention on Psycho-Neuro-Immune Axis, Disease Activity, and Perceived Quality of Life in Rheumatoid Arthritis Patients: A Randomized Controlled Trial.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7492675/ ) Gautam and colleagues recruited adult patients with rheumatoid arthritis and continued with their usual care. They were randomly assigned to either no-treatment or ashtanga yoga practice modified for patients with rheumatoid arthritis. They practiced 5 times per week for 2 hours for 8 weeks. The practice included postures, breathing exercises, meditation, relaxation, and personal lifestyle management. They were measured before and after training for disease activity and quality of life. They also had blood drawn and assayed for biochemical markers of inflammation.

 

They found that in comparison to baseline and the no-treatment group, the yoga group had a significant decrease in rheumatoid arthritis disease activity and a significant increase in their psychological and social quality of life, with greater effects occurring in women than in men. In addition, they found that yoga practice decreased the gene expressions of and levels of pro-inflammatory biochemical markers IL-6, TNF-α, and CTLA4, and a significant increase in TGF-β, an anti-inflammatory marker, suggesting reduced inflammation in the yoga group.

 

This study did not have an active control condition or a long-term follow-up and as such the results must be interpreted with caution. Future studies should include long-term follow-up and an active control condition such as aerobic exercise to determine if the results were due to exercise in general or specifically to yoga practice and whether the benefits were lasting. Nevertheless, the results replicate the findings of other research that yoga practice improves arthritis symptoms and reduces inflammatory responses. The results suggest that yoga practice reduces the inflammatory responses that promote the disease and thereby reduce the disease symptoms which in turn improves the patient’s quality of life. This is good news for these patients signaling that practicing yoga may help relieve their suffering and retard disease progression.

 

So, reduce inflammatory responses and reduce rheumatoid arthritis symptoms with yoga.

Effect of an 8-Week Yoga-Based Lifestyle Intervention on Psycho-Neuro-Immune Axis, Disease Activity, and Perceived Quality of Life in Rheumatoid Arthritis Patients: A Randomized Controlled Trial. Frontiers in Psychology, 11, 2259. https://doi.org/10.3389/fpsyg.2020.02259

 

Abstract

Various external stressors and environmental challenges lead to the provocation of the immune system in autoimmune diseases like Rheumatoid arthritis (RA). The inappropriate immune response further triggers the cascade of inflammatory changes resulting in precipitation of symptoms and hampers quality of life (QOL). The underlying psycho-somatic component of the disease requires a holistic approach to its treatment dimension rather than the use of pharmacotherapy. The applicability of mind-body interventions has become essential in today’s fast-paced life. Yoga, a mind-body technique, alters the mind’s capacity to facilitate systemic functioning at multiple organ system levels. Hence, we conducted this study to evaluate the impact of 8 weeks of a yoga-based lifestyle intervention (YBLI) on psycho-neuro-immune markers, gene expression patterns, and QOL in RA patients on routine medical therapy. A total of 66 patients were randomized into two groups: yoga group or non-yoga group and were assessed for a panel of inflammatory cytokines (IL-6, IL-17A, TNF-α, and TGF-β), mind-body communicative markers (BDNF, DHEAS, β-endorphin, and sirtuin) and transcript levels of various genes (IL-6, TNF-α, NFKB1, TGF-β, and CTLA4). We assessed disease activity and QOL using the DAS28-ESR and WHOQOL-BREF questionnaire, respectively. Yoga group observed significant improvements in the levels of markers, which influenced the psycho-neuro-immune axis (p < 0.001) with an estimated effect size from small to medium range. In the yoga group, there was a significant reduction in DAS28-ESR (p < 0.001) and improvement seen in the physical health, psychological, social relationships domains (p < 0.001) of QOL, except environmental (p > 0.05). The yoga group showed downregulation of IL-6, TNF-α, and CTLA4 and upregulation of TGF-β. These results suggest that a decrease in disease activity after yoga practice is associated with a significant reduction in inflammatory cytokines, the elevation of mind-body communicative markers, and normalization of various transcript levels, which improved QOL. Thus the adoption of YBLI improves clinical outcome in RA, and decreases systemic inflammation by its beneficial effects on psycho-neuro-immune axis and normalization of dysregulated transcripts. Thus YBLI may be used for RA patients as an adjunctive therapy.

Meditative Yoga is Superior to Power Yoga in Reducing Stress and Anxiety

Meditative Yoga is Superior to Power Yoga in Reducing Stress and Anxiety

 

By John M. de Castro, Ph.D.

 

“It may seem like yoga styles are all basically the same, but in reality more than a hundred different schools of yoga exist.” – Justin Young

 

Stress is an integral part of life. But if stress, is high or is prolonged it can be problematic. It can damage our physical and mental health and even reduce our longevity, leading to premature deaths. So, it is important that we develop methods to either reduce or control high or prolonged stress or reduce our responses to it. Mindfulness practices have been found routinely to reduce the psychological and physiological responses to stress.

 

Yoga practice has been shown to have a myriad of benefits for psychological and physical health, social, and spiritual well-being. It is both an exercise and a meditative practice that stresses both mental attention to present moment, movements, breath control, and relaxation. There has, however, not been much attention paid to which components of yoga practice that are important for reducing anxiety and the physiological responses to stress.

 

In today’s Research News article “A Comparison of the Acute Effects of Different Forms of Yoga on Physiological and Psychological Stress: A Pilot Study.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7503485/ ) Marshall and colleagues recruited physically inactive healthy adult women. They were provided with 2 30-minute yoga sessions separated by 48 hours of power yoga and meditative yoga in counterbalanced order. Power yoga emphasized physical postures while meditative yoga focused on mental focus, breathing, and relaxation. Before and after each yoga session the participants were measured for state anxiety and salivary cortisol levels.

 

They found that compared to baseline after meditative yoga there was a significant reduction in anxiety and salivary cortisol while after power yoga there were no significant changes in either measure. This suggests that meditative yoga improves mood and reduces stress while power yoga does not.

 

This study replicates prior research studies that have demonstrated that yoga practice reduces anxiety and stress levels as indicated by salivary cortisol levels. Yoga practice, however, contains a number of different components. The present study separates the exercise component, postures, from the meditative components, mental focus, breathing, and relaxation. The findings suggest that it is these meditative components and not the exercise components that are responsible for yoga’s ability to improve mood and reduce stress.

 

This study should be seen as a pilot study. It was small and of short duration. Yoga practice is not usually confined to only a single brief session but usually occurs as a number of sessions over a sustained period of time. It is possible that different results might occur after several sessions. It remains for future research to examine this.

 

So, meditative yoga is superior to power yoga in reducing stress and anxiety.

 

Power yoga is a general term used to describe a vigorous, fitness-based approach to vinyasa-style yoga. Though many consider power yoga to be superficial “gym yoga,” this style of yoga practice was originally closely modeled on the Ashtanga method.” – Ann Pizer

Abstract

Yoga is a frequently recommended stress management strategy; however, the acute stress response to varying types of yoga are not fully clear. Thus, the purpose of this study was to compare the acute effects of meditative and power yoga on indices of physiological and psychological stress. In a crossover counterbalanced design, physically active females (n = 13; age = 20.8 yrs ± 0.8, height = 164.5 cm ± 6.1, body mass = 65.0 kg ± 13.8) who did not regularly participate in yoga or mindful training enrolled in this study. Participants completed two visits each, with a standardized instructional-video 30-min yoga session with either A) meditative (Hatha style) yoga or B) power (Vinyasa style) yoga. Prior to and immediately after each yoga bout, psychological stress was assessed using the State–Trait Anxiety Inventory (STAI) questionnaire, and salivary cortisol samples were obtained to measure indices of physiological stress. State anxiety scores were significantly lower following meditative yoga (p = 0.047) but were not different following power yoga (p = 0.625). Salivary cortisol levels were significantly lower following meditative yoga (p = 0.020) but not following power yoga (p = 0.242). Results indicate that acute engagement in meditative yoga decreases markers of psychological and physiological stress, while power yoga does not impart a significant stress-relieving benefit. Findings indicate that differing types of yoga may have various stress-relieving capabilities and should be considered by individuals seeking anxiolytic benefits.
