“As is true for meditation and deep breathing exercises, tai chi may help lower blood pressure. . . It’s not as much as you’d see from taking medication, but it’s similar in magnitude to other lifestyle interventions, such as doing modest amounts of exercise and consuming less sodium.” – Harvard Health

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

Obviously, there is a need for alternatives to drugs for reducing blood pressure. Mindfulness practices have been shown to aid in controlling hypertension. Tai Chi is ancient mindfulness practice involving slow prescribed movements. Since Tai Chi is both a mindfulness practice and an exercise, it is particularly acceptable and effective methods to improve cardiovascular health. The research has been accumulating. So, it makes sense to step back and summarize what has been learned.

In today’s Research News article “Meta-Analysis of Randomized Controlled Trials of the Effects of Tai Chi on Blood Pressure.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7563036/ ) Dong and colleagues review, summarize, and perform a meta-analysis of the ability of Tai Chi practice to reduce blood pressure in both normal and hypertensive patients. They identified 24 published controlled trials.

They report that the published research studies found that Tai Chi practice significantly reduced both systolic and diastolic blood pressure in both hypertensive and normal blood pressure participants. But the improvements observed with Tai Chi practice were no greater than those found with other aerobic exercises. The published research studies then demonstrate that Tai Chi practice reduces blood pressure in both normal and hypertensive patients. But is no better than other aerobic exercises.

Thus, exercise in general including Tai Chi practice is good for cardiovascular health. Tai Chi practice, though, has a number of advantages. It is gentle and completely safe, can be used with the elderly and sickly, is inexpensive to administer, can be performed in groups or alone, at home or in a facility or even public park, and can be quickly learned. In addition, it can also be practiced in social groups without professional supervision. This can make it fun, improving the likelihood of long-term engagement in the practice. Hence, Tai Chi practice may be better for cardiovascular health than other exercises because it is more likely to be engaged in and maintained.

So, reduce blood pressure with Tai Chi.

“Tai chi may be just as effective as popular methods for lowering blood pressure, such as weight loss and lowered sodium intake.” – Abbott

Abstract

Objectives

The purpose of this study was to investigate the influences of Tai Chi on blood pressure (BP) using the meta-analysis.

Methods

This paper used 6 e-resource databases, and randomized controlled trials on the role of Tai Chi on blood pressure were retrieved. Besides, the meta-analysis was conducted according to the guidelines of the Moose-recommendations and applied with Review Manager 5.3, and the risk of bias assessment was performed with the Cochrane Collaboration’s tool. The inclusion, data extraction, and risk of bias assessment were independently finished by two researchers.

Results

There are 24 trials meeting the criteria of inclusion and the results were reviewed. The meta-analysis indicates that, compared with no exercise, Tai Chi had the influence of lowering systolic blood pressure (mean difference = −6.07, 95%CI (−8.75, −3.39), P < 0.00001) and diastolic blood pressure (mean difference MD = −3.83, 95%CI (−4.97, −2.69), P < 0.00001). No significant discrepancies in all outcomes between Tai Chi and other aerobic exercises were discovered.

Conclusion

Tai Chi can significantly reduce systolic and diastolic pressure than inactivity. However, Tai Chi does not show advantages in reducing blood pressure compared to other aerobic exercises.

Improve the Quality of Life with Aging with Tai Chi

By John M. de Castro, Ph.D.

“Over the past few years, tai chi has been at the top of the list of “alternative therapies” with benefits that . . . helps senior improve their balance, mood and joint health.” – IlluminAge

The aging process involves a systematic progressive decline in every system in the body, the brain included. This markedly reduces the quality of life in aging individuals. There is some hope for age related decline, however, as there is evidence that it can be slowed. There are some indications that physical and mental exercise can reduce the rate of decline. For example, contemplative practices such as meditation, yoga, and Tai Chi or qigong have all been shown to be beneficial in slowing or delaying physical and mental decline with aging. The research findings have been accumulating. So, it makes sense to step back and summarize what has been learned about the effectiveness of Tai Chi for reducing the decline in quality of life during aging.

In today’s Research News article “Effectiveness of Tai chi exercise on overall quality of life and its physical and psychological components among older adults: a systematic review and meta-analysis.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7485323/ ) Wang and colleagues review, summarize, and perform a meta-analysis of the published research studies of the effectiveness of Tai Chi practice in reducing the age related decline in quality of life. They identified 10 published randomized controlled trials with a total of 1170 participants who were aged 50 years and older.

They report that the published research found that Tai Chi practice significantly improved the quality of life in older and elderly individuals. This improvement was significant particularly for physical component of quality of life. But was not significant for the psychological component. This is not surprising as Tai Chi practice has been shown to improve strength and balance and reduce the likelihood of falls in older individuals. These benefits should improve their physical well being and reduce the likelihood of injury.

It is a bit surprising that the psychological component of quality of life was not improved. Tai Chi is often practiced in social groups while the elderly are often isolated and have high levels of loneliness. So, it would be expected that the social interactions occurring with Tai Chi practice would improve their psychological well-being. This needs to be further researched.

Tai Chi is an ancient mindfulness practices involving slow prescribed movements. It is gentle and completely safe, can be used with the healthy and sickly, is inexpensive to administer, can be performed in groups or alone, at home or in a facility or even public park, and can be quickly learned. In addition, it can be practiced in social groups without professional supervision. This can make it fun, improving the likelihood of long-term engagement in the practice. This makes Tai Chi an almost ideal practice for the improvement of quality of life in aging individuals.

So, improve the quality of life with aging with Tai Chi.

Abstract

With the aging of the world’s population, the quality of life of older adults is becoming more important. There are many studies on the use of Tai chi exercise, a popular form of mind-body exercise practiced by older adults. However, the effectiveness of Tai chi exercise on the quality of life of older adults is unclear. For this systematic review and meta-analysis, six databases (PubMed, CENTRAL, CINAHL, EMBASE, Scopus, CNKI) were searched in English and Chinese languages to screen for relevant randomized controlled trials (RCT), and their risk of bias was assessed by two independent reviewers. The results of quality of life, physical component, and psychological component among older adults were meta-analyzed using RevMan5.3 software. The search retrieved 2577 records. After screening, a total of 10 RCTs were included in this evaluation, with a total of 1170 participants. The meta-analysis showed that compared with the control group, Tai chi exercise had a significant impact on the overall quality of life (SMD=1.23; 95%CI: 0.56–1.98; P<0.0001), and on the physical component of quality of life (MD=5.90; 95%CI: 1.05–10.75; P=0.02), but no significant impact on the psychological component of quality of life. This study had high heterogeneity. The results of this study suggest the potential use of Tai chi exercise as an activity for increased quality of life in older adults. Future research may enhance experimental rigor and explore the rationale behind Tai chi exercise.

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.

Improve Autonomic Nervous System Function and Well-Being in Cancer Survivors with Mind-Body Practices.

Improve Autonomic Nervous System Function and Well-Being in Cancer Survivors with Mind-Body Practices.

By John M. de Castro, Ph.D.

“Tai Chi and Qigong are ancient forms of exercise that fit the bill for helping patients with cancer get moving and improve their overall sense of well-being. Tai Chi practice can help with pain conditions, especially pain involving muscles and joints; it can also reduce stress and anxiety and improve the quality of sleep.” – Susan Yaguda

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

Mindfulness training has been shown to help with cancer recovery and help to relieve chronic pain. It can also help treat the residual physical and psychological symptoms, including stress, sleep disturbance, fear, and anxiety and depression. Mind-body practices such as Tai Chi or Qigong, and yoga have been shown to be effective in improving the psychological symptoms occurring in breast cancer patients. These practices work to relieve the emotional distress of cancer survivors.

A potential mechanism by which mind-body practices may relieve emotional distress is by altering the balance in the autonomic nervous system. A measure of this balance is Heart Rate Variability (HRV). It refers to the change in the time intervals between consecutive heart beats. Higher levels of HRV are indicative of flexibility in the Autonomic Nervous System and are associated with adaptability to varying environments. Increased heart rate variability signals greater relaxation in the autonomic nervous system with a predominance of parasympathetic (relaxation) activity over sympathetic (activation) activity. This all signals greater physiological relaxation.

In today’s Research News article “Mind-Body and Psychosocial Interventions May Similarly Affect Heart Rate Variability Patterns in Cancer Recovery: Implications for a Mechanism of Symptom Improvement.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7425257/ ) Larkey and colleagues recruited female breast cancer survivors and randomly assigned them to receive 12 weeks of either Tai Chi or Sham-Tai Chi practice. Sham-Tai Chi used the same movements but did not incorporate breath control or meditative states. They were measured before and after training for fatigue, sleep, and depression and the electrocardiogram was measured and analyzed for Heart Rate Variability (HRV).

They found that after Tai Chi Practice, but not Sham-Tai Chi, there were significant reductions in fatigue and depression and significant improvements in sleep. In addition, in the Tai Chi group there was a significant reduction in low coherence Heart Rate Variability (HRV). Also, the greater the change, over training, in high coherence HRV the greater the reduction in depression levels.

This study replicates previous findings that Tai Chi practice reduces fatigue, and depression, and improves sleep. And produces changes in Heart Rate Variability (HRV). But this study used a unique control, comparison, condition of Sham-Tai Chi that had the same movements but lacked the breath control and meditative state of true Tai Chi practice. This suggests that it is not the movements of Tai Chi that produces the benefits but the mindfulness components that are essential.

The study also presents some evidence as to the mechanism by which Tai Chi practice improves that physical and psychological state of cancer survivors. The observed changes in Heart Rate Variability (HRV) are indicative of greater relaxation in the autonomic nervous system with a predominance of parasympathetic (relaxation) activity over sympathetic (activation) activity. This suggests that Tai Chi practice results in a physiological relaxation that in turn may be responsible for the physical and psychological benefits of the practice.

Some advantages of Tai Chi practice include the facts that it is not strenuous, involves 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. It can also be practiced without professional supervision and in groups making it inexpensive to deliver and fun to engage in. This makes Tai Chi practice an excellent means to improve the physical and psychological symptoms experienced by cancer survivors.

So, improve autonomic nervous system function and well-being in cancer survivors with mind-body practices.

Mind-Body and Psychosocial Interventions May Similarly Affect Heart Rate Variability Patterns in Cancer Recovery: Implications for a Mechanism of Symptom Improvement. Integrative cancer therapies, 19, 1534735420949677. https://doi.org/10.1177/1534735420949677

Abstract

Background:

Advancements in early detection and treatment of cancer have led to increased survival rates and greater need to identify effective supportive care options for resolving symptoms of survivorship. Many non-pharmacological approaches to symptom management during and after cancer treatment involve emotional self-regulation as a central strategy for improving well-being. Identifying commonalities among these strategies’ mechanisms of action may facilitate understanding of what might be useful for optimizing intervention effects. Heart rate variability (HRV) parameters are indicative of improved autonomic nervous system (ANS) balance and resiliency and reduced emotional distress and are thus identified as a mechanism to discuss as a marker of potential for intervention efficacy and a target for optimization.

Methods:

HRV data from 2 studies, 1 examining a mind-body intervention and 1 examining a psychosocial intervention, are presented as a point of discussion about preliminary associations between the interventions, change in HRV, and emotional distress reduction.

Results:

HRV significantly decreased in sympathetic activity in response to a mind-body intervention (Qigong/Tai Chi), and increased vagal tone in response to a psychosocial (storytelling) intervention. In both, these changes in HRV parameters were associated with improved emotional states.

Conclusion:

Our preliminary data suggest that HRV may serve as an important marker of underlying changes that mediate emotional regulation; this observation deserves further investigation. If identified as a worthy target, focusing on interventions that improve HRV within the context of interventions for cancer patients may be important to key outcomes and clinical practice.

Improve the Physical and Psychological Well-Being of Cancer Survivors with Mind-Body Practices

By John M. de Castro, Ph.D.

“Mind-body techniques such as meditation, yoga, tai chi, and qigong have been found to lower distress and lead to improvements in different aspects of quality of life. . . to help patients manage the psychosocial challenges of diagnosis and treatment of cancer.” – Alejandro Chaoul

Mindfulness training has been shown to help with cancer recovery and help to relieve chronic pain. It can also help treat the residual physical and psychological symptoms, including stress, sleep disturbance, fear, and anxiety and depression. Mind-body practices such as Tai Chi or Qigong, and yoga have been shown to be effective in improving the psychological symptoms occurring in breast cancer patients. There have been a number of research studies conducted on the effectiveness of mind-body practices for the relief of the physical and mental symptoms of cancer survivors. So, it makes sense to summarize what has been learned.

In today’s Research News article “Effects of Mind-Body Exercise in Cancer Survivors: A Systematic Review and Meta-Analysis.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7487122/ ) Duan and colleagues

review, summarize, and perform a meta-analysis of the published randomized controlled trials of the effectiveness of mind-body practices for the treatment of cancer survivors. They found 15 published controlled clinical trials including a total of 1461 patients.

They report that the published controlled clinical trials found that mind-body practices produced significant increases in physical fitness and sleep quality and decreases in fatigue, depression, anxiety, and body mass index. Of the different mind-body practices Tai Chi practice appears to be superior in decreasing fatigue and sleep problems, Qigong practice appears to be superior in increasing physical fitness, while yoga practice appears to be superior in decreasing depression and anxiety.

These results are important in that they demonstrate that mind-body practices are effective in relieving the psychological and physical symptoms present in cancer survivors. These findings are generalizable in that a wide variety of types of cancers with a wide variety of patients were included. This suggests that mind-body practices are applicable to relieving the suffering of cancer survivors in general.

The review suggested, however, that different mind-body practices may be superior in addressing specific symptoms. Qigong appears to be best for improving physical fitness, Tai Chi appears to be best for reducing sleep problems and fatigue, and yoga appears to be best for alleviating mental disorders. So, tailoring the program for the greatest problems experienced by specific cancer patients may maximize the benefits for the individual patient.

So, improve the physical and psychological well-being of cancer survivors with mind-body practices.

Abstract

Objective

Mind-body exercise may have potential benefits for cancer survivors according to previous studies. We performed a systematic review and meta-analysis to summarize the published evidence and evaluate the safety and efficacy of mind-body exercise on general quality of life (QOL) and symptom management in cancer survivors.

Methods

Four English language databases were systematically searched for existing randomized controlled trials (RCTs) of mind-body exercise in cancer survivors from database inception through October 23, 2019. Methodological quality was appraised with the Cochrane Risk of Bias tool. A meta-analysis of comparative effects was performed using the Review Manager v.5.3 software.

Results

Fifteen studies encompassing 1461 patients were included. Analysis results showed that mind-body exercise could have a statistically significant effect on the outcomes of physical fitness, fatigue, sleep quality, depression, anxiety, and BMI, while effects on general QOL and stress were not statistically significant (all p > 0.05). No serious adverse events were reported.

Conclusions

The current evidence demonstrates that mind-body exercise is relatively safe and modestly effective for symptom management in cancer survivors. Furthermore, randomized trials with larger sample sizes and of higher methodological quality are needed to confirm these results.

Improve the Quality of Sleep with Tai Chi

Improve the Quality of Sleep with Tai Chi

By John M. de Castro, Ph.D.

“Tai Chi significantly improved sleep quality for healthy patients and those with chronic health conditions. Their physical performance and psychological well being improved compared with the control group. Along with better sleep, came a reduction in pain. “ – Balanced Life

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

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

Tai Chi is an ancient mindfulness practice involving slow prescribed movements. It is gentle and completely safe, can be used with the elderly and sickly, is inexpensive to administer, can be performed in groups or alone, at home or in a facility or even public park, and can be quickly learned. In addition, it can also be practiced in social groups without professional supervision. This can make it fun, improving the likelihood of long-term engagement in the practice. Indeed, studies have shown that Tai Chi practice is effective in improving sleep. The evidence is accumulating. So, it makes sense to step back and summarize what has been learned.

In today’s Research News article “Tai Chi Chuan for Subjective Sleep Quality: 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/PMC7439202/ ) Si and colleagues review, summarize, and perform a meta-analysis of published randomized controlled trials of the effectiveness of Tai Chi in improving sleep quality. They identified 25 published randomized controlled with adults as participants.

They report that the published research studies found that Tai Chi practiced produced a significant improvement in sleep quality with moderate effect size. They report that the optimum effects were produced by practices that lasted 60 to 90 minutes. Tai Chi was effective in both healthy and clinical populations but it had its greatest effects on sleep in healthy populations. In addition, Tai Chi practice produced large significant improvements in the sleep quality of Asian participants but not American participants.

Importantly, the largest effects were seen in studies with low methodological quality while 8 studies with the highest methodological quality did not observe significant improvements in sleep quality. The primary differences between low and high methodological quality studies revolved around how much the participants knew about the study and its intentions. This suggests that participant expectancy factors may be very important here.

That participant expectancies may be driving the results is further reflected in the fact that the largest effects were present in Asian participants while they were not significant in American participants. Tai Chi has been practiced in Asia for centuries and is believed to be very beneficial. It has only recently been practiced in America and Americans are generally ignorant or skeptical of its benefits. Hence, Asian participants would be expected to have the largest participant expectancies of positive benefits and they were the only population showing significant effects.

In summary, the results suggest that 60 to 90 minutes of Tai Chi practice produce improvements in sleep quality in healthy and clinical populations. But there is a strong suspicion that participant expectancies of Tai Chi efficacy my be responsible for the effects. There is a need, then, for more tightly controlled studies to determine if Tai Chi and not participant bias is responsible for the established benefits.

So, improve the quality of sleep with Tai Chi.

Evidence-based complementary and alternative medicine : eCAM, 2020, 4710527. https://doi.org/10.1155/2020/4710527

Abstract

Background

This review aims to investigate the efficacy of Tai Chi Chuan on subjective sleep quality among adults.

Methods

We systematically searched PubMed, Embase, Cochrane Library, Scopus, CNKI (China National Knowledge Infrastructure), and the Wanfang Database from their inception to August 2019 and identified 25 eligible studies that were published in both English and Chinese.

Results

24 out of 25 studies were identified to be high-quality studies according to the PEDro scale. The pooled results confirmed that Tai Chi Chuan elicited moderate improvements in subjective sleep quality (SMD = −0.512, 95% CI [−0.767, −0.257], P < 0.001). Notably, Tai Chi Chuan yielded more significant effects on sleep quality among the healthy population (SMD = −0.684, 95% CI [−1.056, −0.311], P < 0.001) than the clinical population (SMD = −0.395, 95% CI [−0.742, −0.047], P=0.026) and more benefits among the Asian population (SMD = −0.977, 95% CI [−1.446, −0.508], P < 0.001) than the American population (SMD = −0.259, 95% CI [−0.624, 0.105], P=0.164). After controlling the methodological quality of studies, it has been noted that Asians could achieve the most significant sleep-promoting benefit when Tai Chi Chuan was practiced between 60 and 90 min per session.

Conclusions

Available data implied that subjective sleep quality was improved via Tai Chi training, but more thorough studies must be executed to ascertain our findings and optimize Tai Chi practices accordingly toward various populations.

Meditation Improves Health and Well-Being Through Epigenetic Mechanisms

By John M. de Castro, Ph.D.

“It seems unusual that something as simple and easy as meditating could improve your health, but these studies demonstrate an epigenetic link between meditation and its potential disease-reducing benefits.” – Bailey Kirkpatrick

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 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.

Meditation practice has been shown to improve health and longevity. One way it appears to act is by altering the genes which govern cellular processes in our bodies. The genes dictate all of the chemical processes in our bodies including immune and inflammatory responses. The ability of outside influences to affect gene expression is known as epigenetics. There have been a number of research studies of the of the epigenetic effects of mindfulness practices. So, it makes sense to summarize what has been learned regarding the epigenetic alterations in gene expressions produced by mindfulness practices to determine if these effects are the intermediary between meditation and health.

In today’s Research News article “Molecules of Silence: Effects of Meditation on Gene Expression and Epigenetics.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7431950/) Venditti and colleagues review and summarize the published research studies of the effects of mindfulness on gene expression.

They report that the published research found that sitting and walking meditation, Tai Chi, and Yoga produce wide-ranging changes in gene expression including slowing of the age-related methylation of the genes. They report that the epigenetic changes seen alter genes involved in metabolism, inflammatory processes, oxidative stress, and DNA damage response. In fact, they report that mindfulness practices produce epigenetic changes that are the opposite to those produced by stress.

These findings are important for understanding the ability of mindfulness practices to promote health and slow the aging process. By reversing the changes that stress produces in gene expression, mindfulness practices can prevent or reverse the harmful consequences of stress on the body. This may well be one of the mechanisms that underlie the health benefits of mindfulness practices.

So, meditation improves health and well-being through epigenetic mechanisms.

“a single 8-hour mindfulness meditation retreat can rapidly alter methylation levels that affect epigenetic expression in genes among experienced meditators. Involved genes include those that regulate inflammation, immune cell metabolism, DNA repair, cellular aging, RNA metabolism, protein translation, cell adhesion, and neurotransmission.” – AMRA

Abstract

Many studies have consistently demonstrated an epigenetic link between environmental stimuli and physiological as well as cognitive responses. Epigenetic mechanisms represent a way to regulate gene activity in real time without modifying the DNA sequence, thus allowing the genome to adapt its functions to changing environmental contexts. Factors such as lifestyle, behavior, and the practice of sitting and moving mindful activities have been shown to be important means of environmental enrichment. Such practices, which include mindfulness meditation, Vipassana, Yoga, Tai Chi, and Quadrato Motor Training, have been reported to positively impact well-being. In fact, they can be considered emotional and attentional regulatory activities, which, by inducing a state of greater inner silence, allow the development of increased self-awareness. Inner silence can therefore be considered a powerful tool to counteract the negative effects of overabundant environmental noise, thanks to its power to relieve stress-related symptoms. Since all these positive outcomes rely on physiological and biochemical activities, the molecular and epigenetic mechanisms influenced by different mindful practices have recently started to be investigated. Here, we review some of the findings that could allow us to uncover the mechanisms by which specific practices influence well-being.

Improve the Immune System with Tai Chi and Qigong Practice

By John M. de Castro, Ph.D.

“Tai chi might have a strong effect on the immune system because it manages to bring exercise, relaxation, and meditation together in “one behavioral intervention.” – Havard Health

Mindfulness training has been shown to be effective in improving physical and psychological health and particularly with the physical and psychological reactions to stress. Techniques such as Mindfulness Training, Yoga practice and Tai Chi or Qigong practice have been demonstrated to be effective. An important benefit of mindfulness practices that may be responsible for the improved health may be that it strengthen the immune system, the body’s primary defense against disease. Through a series of steps called the immune response, this system attacks organisms and substances that invade body systems and cause disease.

Tai Chi and Qigong have been practiced for thousands of years with benefits for health and longevity. Tai Chi and Qigong trainings are designed to enhance function and regulate the activities of the body through regulated breathing, mindful concentration, and gentle movements. Tai Chi and Qigong are not strenuous, involving slow gentle movements, and are safe, having no appreciable side effects, they are appropriate for all ages including the elderly and for individuals with illnesses that limit their activities or range of motion.

Tai Chi and Qigong practice have 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. So, with the research accumulating, it makes sense to step back and review the research on the effects of Tai Chi and Qigong practice on the immune system.

In today’s Research News article “The Effects of Tai Chi and Qigong on Immune Responses: A Systematic Review and Meta-Analysis.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7400467/) Oh and colleagues review, summarize, and perform a meta-analysis of the effects of Tai Chi and Qigong practice on immune system function. They identified 19 published research randomized controlled trials that included a total of 1686 participants, including both healthy participants and participants with illnesses.

They report that the published randomized controlled trials found that Tai Chi and Qigong practice produced a small but significant increase in innate immune cells, including dendritic cells, eosinophils, monocytes, and neutrophils. They also produced a small but significant increase in adaptive immune cells including the Th1/Th2 ratio and the Tc1/Tc2 ratio, B lymphocytes, and VZV-cell-mediated immunity. Tai Chi and Qigong practice also produced a small but significant decrease in inflammatory C-reactive protein, interleukin 6, 12, and 18, Interferon-γ, and Nuclear Factor-κB.

The meta-analysis revealed that the safe and gentle practice of Tai Chi and Qigong results in beneficial enhancements of the immune system. The practices increase the numbers of innate and adaptive immune system cells and a decrease in proinflammatory molecules. They both strengthen immunity and reduce inflammation. These effects would tend to make the practitioners of Tai Chi and Qigong more resistant to disease and thereby healthier.

The practice of Tai Chi and Qigong can be easily learned inexpensively by large numbers of people of a wide variety of ages and health conditions. This would make these practices highly scalable and ideal for improving public health. This includes an improved ability to fend off a viral pandemic such as Covid-19. It’s amazing that such a simple practice could have such a beneficial impact on health.

So, improve the immune system with Tai Chi and Qigong practice.

“Your health is only as good as your immune system is strong. Numerous studies demonstrate Tai Chi’s positive effect on the immune system. However, Tai Chi does require practice and discipline and strengthening your immune system will not happen overnight.” – Balanced Life

The Effects of Tai Chi and Qigong on Immune Responses: A Systematic Review and Meta-Analysis. Medicines (Basel, Switzerland), 7(7), 39. https://doi.org/10.3390/medicines7070039

Abstract

Background: Effective preventative health interventions are essential to maintain well-being among healthcare professionals and the public, especially during times of health crises. Several studies have suggested that Tai Chi and Qigong (TQ) have positive impacts on the immune system and its response to inflammation. The aim of this review is to evaluate the current evidence of the effects of TQ on these parameters. Methods: Electronic searches were conducted on databases (Medline, PubMed, Embase and ScienceDirect). Searches were performed using the following keywords: “Tai Chi or Qigong” and “immune system, immune function, immunity, Immun*, inflammation and cytokines”. Studies published as full-text randomized controlled trials (RCTs) in English were included. Estimates of change in the levels of immune cells and inflammatory biomarkers were pooled using a random-effects meta-analysis where randomised comparisons were available for TQ versus active controls and TQ versus non-active controls. Results: Nineteen RCTs were selected for review with a total of 1686 participants and a range of 32 to 252 participants within the studies. Overall, a random-effects meta-analysis found that, compared with control conditions, TQ has a significant small effect of increasing the levels of immune cells (SMD, 0.28; 95% CI, 0.13 to 0.43, p = 0.00), I2 = 45%, but not a significant effect on reducing the levels of inflammation (SMD, −0.15; 95% CI, −0.39 to 0.09, p = 0.21), I2 = 85%, as measured by the systemic inflammation biomarker C-reactive protein (CRP) and cell mediated biomarker cytokines. This difference in results is due to the bidirectional regulation of cytokines. An overall risk of bias assessment found three RCTs with a low risk of bias, six RCTs with some concerns of bias, and ten RCTs with a high risk of bias. Conclusions: Current evidence indicates that practising TQ has a physiologic impact on immune system functioning and inflammatory responses. Rigorous studies are needed to guide clinical guidelines and harness the power of TQ to promote health and wellbeing.

Improve Health and Treat Illness with Qigong

By John M. de Castro, Ph.D.

“in order to do qigong … we have to be pretend to be empty, so the first thing to empty is the mind, so we try not to think of anything and only listen to our breathing, relax all the strength and relax the mind, so it’s some kind of meditation.” – Joe Lok

Tai Chi and Qigong are ancient mindfulness practices involving slow prescribed movements. They are gentle and completely safe, can be used with the elderly and sickly, are inexpensive to administer, can be performed in groups or alone, at home or in a facility or even public park, and can be quickly learned. In addition, they can also be practiced in social groups without professional supervision. This can make it fun, improving the likelihood of long-term engagement in the practice.

Tai Chi and Qigong are both mindfulness practices and exercises. They have been shown to be beneficial to the health and well-being of individuals of a variety of ages, but particularly the elderly. They also improve the symptoms of a variety of diseases. The studies of the benefits for health of Tai Chi and Qigong are accumulating and so it makes sense to take a moment to summarize what has been learned.

In today’s Research News article “Benefits of Qigong as an integrative and complementary practice for health: a systematic review.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7365612/) Toneti and colleagues review and summarize the published research studies of the benefits for health of Qigong practice. They identified 28 published clinical trials.

They report that the published research studies found that Qigong practice significantly promotes health and is effective in the prevention and rehabilitation of diseases in adults and the elderly. The evidence supports the effectiveness of Qigong practice in treating the symptoms of cancer, fibromyalgia, Parkinson’s disease, cardiovascular disease, and COPD. It has also been shown to be effective in reducing chronic pain including low back pain, cervical pain, and osteoarthritis pain. In addition, it has been shown to be effective in reducing perceived stress, burnout, fatigue, social isolation, and depression.

Hence, the available published research suggests that Qigong practice is effective in promoting physical and psychological health in healthy people and people with diseases at a variety of ages including the elderly. These are impressive benefits for a gentle and safe practice that can be rolled out to a wide audience at low cost. This suggests that people should be encouraged to participate in Qigong practice to promote their health and well-being.

So, improve health and treat illness with Qigong.

“Qi gong and tai chi are relaxing ways to improve your flexibility and balance. Both are great ways to stay active and vital. The gentle, flowing movements are easy on the joints.” – Jodi Helmer

Abstract

Objective:

to analyze, in the literature, evidence about the benefits of the integrative and complementary practice of Qigong with regard to the health of adults and the elderly.

Method:

a systematic review by searching for studies in the PubMed, CINAHL, LILACS, EMBASE and Cochrane Library databases. Randomized and non-randomized clinical trials were included; in Portuguese, English and Spanish; from 2008 to 2018. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses strategy was adopted, as well as the recommendation of the Cochrane Collaboration for assessing the risk of bias in the clinical trials analyzed.

Results:

28 studies were selected that indicated the benefit of the practice to the target audience, which can be used for numerous health conditions, such as: cancer; fibromyalgia; Parkinson’s disease; Chronic Obstructive Pulmonary Disease; Burnout; stress; social isolation; chronic low back pain; cervical pain; buzz; osteoarthritis; fatigue; depression; and cardiovascular diseases. However, there was a great risk of bias in terms of the blinding of the research studies.

Conclusion:

the practice of Qigong produces positive results on health, mainly in the medium and long term. This study contributes to the advancement in the use of integrative and complementary practices in nursing, since it brings together the scientific production in the area from the best research results available.

Decrease Hypertension with Tai Chi

Decrease Hypertension with Tai Chi

By John M. de Castro, Ph.D.

“Tai chi may be just as effective as popular methods for lowering blood pressure, such as weight loss and lowered sodium intake. . . tai chi may positively affect blood cholesterol, related lipids and inflammation. This means that enjoying tai chi regularly may lower your chance of heart disease.” – Abbot

Obviously, there is a need for alternative to drug treatments for hypertension. Mindfulness practices have been shown to aid in controlling hypertension. Mindful movement practices such Tai Chi and Qigong are ancient Chinese practices involving mindfulness and gentle movements. They are easy to learn, safe, and gentle. So, it may be appropriate for patients with hypertension who lack the ability to engage in strenuous exercises. Indeed, Qigong practice has been shown to reduce blood pressure. There have been a number of studies performed and it is useful to summarize what has been learned.

In today’s Research News article “The Efficacy of Tai Chi and Qigong Exercises on Blood Pressure and Blood Levels of Nitric Oxide and Endothelin-1 in Patients with Essential Hypertension: 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/PMC7414352/) Liu and colleagues review, summarize, and perform a meta-analysis of the effectiveness of Tai Chi practice in treating hypertension. They found 9 published randomized controlled trials including a total of 516 patients.

They report that the published research found that Tai Chi practice produced a significant reduction in both systolic and diastolic blood pressure and blood endothelin-1 levels and significant increases in blood nitrous oxide levels. Endothelin-1 is a powerful vasoconstrictor and Nitrous Oxide is a powerful vasodilator. So, the reduced levels of Endothelin-1 and increased levels of Nitrous Oxide in patients performing Tai Chi may be a physiological mechanism by which the practice lowers blood pressure.

These findings suggest that Tai Chi practice is a safe and effective treatment to lower blood pressure in patients with hypertension. Some advantages of Tai Chi include the facts that it is not strenuous, involves 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. It can also be practiced without professional supervision and in groups making it inexpensive to deliver and fun to engage in. This makes Tai Chi practice an excellent treatment for hypertension.

So, decrease hypertension with Tai Chi.

“High blood pressure can precede cardiovascular complications, such as a heart attack, so it is important to keep it in check. If your blood pressure is too high, there is a simple exercise you can do at home. . . Evidence suggests tai chi, a mind-body practice that has its origin Chinese martial arts, can lower high blood pressure.” – Adam Chapman

The Efficacy of Tai Chi and Qigong Exercises on Blood Pressure and Blood Levels of Nitric Oxide and Endothelin-1 in Patients with Essential Hypertension: A Systematic Review and Meta-Analysis of Randomized Controlled Trials. Evidence-based complementary and alternative medicine : eCAM, 2020, 3267971. https://doi.org/10.1155/2020/3267971

Abstract

Objective

Tai Chi and Qigong are the two similar traditional Chinese wellness exercises. A strong body of published clinical randomized controlled trials (RCTs) has investigated the health benefits of Tai Chi and Qigong exercises (TCQE) in patients with essential hypertension (EH). This is the first meta-analysis to evaluate the efficacy of TCQE on blood pressure (BP) and blood levels of nitric oxide (NO) and endothelin-1 (ET-1) in EH patients and explore the potential antihypertensive mechanism of TCQE.

Methods

We conducted a literature retrieval for Chinese and English studies in seven databases from their respective inceptions until January 14, 2020. All RCTs examining clinical efficacy of TCQE for EH patients were considered. The major therapeutic outcomes of TCQE were changes in the blood levels of NO, ET-1, and BP in EH patients. Methodological quality of the included RCTs was detected via The Cochrane Risk of Bias tool. We evaluated the data reported and performed the meta-analysis by Review Manager 5.3 software.

Results

9 RCTs involving 516 EH patients were included. The intervention duration lasted from 1.5 months to 6 months. The results of comprehensive analysis showed that compared with control interventions, experimental interventions were more effective in reducing the systolic blood pressure and the diastolic blood pressure and contributed higher blood levels of NO and lower blood levels of ET-1.

Conclusions

TCQE could be an effective complementary and alternative therapy for EH. The lower BP in EH patients who practice TCQE may have some connection with exercise-related increased blood NO levels and decreased blood ET-1 levels. However, further research is needed to make clear the efficacy of TCQE in management of EH and the mechanism of lowering BP in TCQE.
