“mindfulness training on focusing on the present moment may develop control of attention, or executive function. This enhances capacity for sustained attention, attention switching, and inhibition of elaborative processing, thereby increasing our mastery over the content of our thoughts and actions. . . this amplifies our ability to self-regulate, allowing us to redirect our attention from rumination and depressogenic thoughts back to the experience of the present moment, thus decreasing negative affect and improving psychological health.” – Richard Chambers

Mindfulness practices such as meditation, yoga, and tai chi/qigong have been shown to have a myriad of positive benefits for the practitioner and they have been shown to alter a large variety of cognitive (thought) processes, such as attentional ability, memory, verbal fluency, critical thinking, learning, analytic thinking, mathematical ability, higher level (meta-cognitive) thinking, and cognitive reappraisal. There have not, however, been direct comparisons made between the practices to establish which may be superior for the improvement of which cognitive processes. In order to optimize the effectiveness of mindfulness practices to improve thinking it is important to determine the effective components of each practice.

Teng and Lien compare the effectiveness of trainings for 4-weeks, twice a week for 90 minutes each, of mindful movements, or meditation, or a no treatment control. The mindful movement practice was termed Body-Mind Axial Awareness (BMAA) practice. It is very similar to tai chi except that the movements are not precisely choreographed and programmed. Chan meditation practice was used. It is very similar to Zen meditation and emphasizes breath following. They measured mindfulness, working memory ability, response inhibition (Stroop task), sustained attention and attentional switching ability.

They found that both the meditation and the mindful movement practices produced significant increases in mindfulness, in particular the observing and acting with awareness facets of mindfulness. They also found that the mindful movement practice produced a significant increase in working memory ability and sustained attention while the meditation training produced a significant increase in attentional switching ability. The groups did not differ in response inhibition ability. Hence, meditation practice appears to improve mindfulness and the ability to switch attention while the mindful movement practice improves mindfulness and working memory.

Increases in mindfulness, especially with the observing and acting with awareness facets, are routinely found with all mindfulness practices. So, these findings are not surprising and do not signal a difference between practices. The mindful movement practice requires continuous sustained attention in order to produce smooth movement sequences, so it makes sense that this practice would produce better sustained attention and therefore reduce mind wandering. This may, in turn, improve working memory ability as it improves sustained attention on the contents of memory, thereby reducing loss from working memory. It is possible that the training in focusing attention in the meditation practice that requires shifting attention back to the breath after mind wandering may be responsible for the improvements in attentional switching seen with meditation practice.

Although the equivalence of the mindful movement practice and the meditation practice was well maintained, one difference would be impossible to make equivalent and that is effects of the practice on the cardiovascular system. Mindful movement practice would be expected to raise heart rate, blood pressure, and metabolic rate while meditation would be expected to reduce them. In addition, the no treatment control is a weak control condition and a light exercise condition practiced over equivalent periods of time would be a much better comparison condition. So, for future research it might be useful to include a light exercise (e.g. walking) control condition.

Regardless improve thought executive function with mindfulness.

PMID: 27038245

Abstract

The short-term training effects on various executive functions (EFs) by a movement-based contemplative practice (MBCP) are examined. Three aspects of EFs (working memory capacity, inhibition, switching) are assessed before and after a month-long 12-h training period using Body-Mind Axial Awareness (BMAA) principles that Confucius followers have practiced for more than 2000years. A mindfulness-based practice (Chan-meditation) and a waiting-list control group served as contrast groups. Our results showed that the BMAA group performed better on the task that measured working memory capacity than did the Chan-meditation and the waiting-list groups after training. In addition, the Chan-meditation groups outperformed the control group on attentional switching, a novel finding for this kind of practice. Our findings not only show a new effect of short-term MBCPs on EFs, but also indicate movement-based and mindfulness-based contemplative practices might benefit development of various aspects of EFs in different ways.

Minority and Low Education Groups are Less Likely to Practice Mindfulness

“Despite increased attention to diversity issues, ethnic minorities are still underrepresented in the field of psychology. Baseline knowledge on the effectiveness of treatments for ethnic minority groups is limited.” – Janice Ya Ken Cheng

Mindfulness practices have gone mainstream in western culture. This has not been driven by theoretical, philosophical, or religious reasons but by pragmatic ones. Mindfulness practices have been found to be very beneficial to the practitioner of all ages from children, to adults, to the elderly. They have been shown to improve the psychological and physical health of otherwise healthy individuals and to be helpful in treating both mental and physical illnesses. A variety of mindfulness techniques have been shown to be effective including meditation, mindfulness based stress reduction (MBSR), mindfulness based cognitive therapy (MBCT), Acceptance and Commitment therapy (ACT), mindful movement practices such as tai chi and qigong, and yoga. It is no wonder that these practices have spread rapidly in modern western culture.

At present, it is not known whether these practices have spread uniformly through the population of have been adopted primarily by specific subgroups. For the most part, mindfulness practices require a teacher, at least initially, and thus can incur costs. This suggests that there may be socioeconomic barriers to participation. In addition, because mindfulness practices have spread through the printed media, education level may be a factor in their adoption. To help promote the adoption of these healthy techniques it is important to know which groups are not currently participating in large numbers and what might be the barriers for participation.

In today’s Research News article “Engagement in Mindfulness Practices by U.S. Adults: Sociodemographic Barriers.” See: https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1219971614693429/?type=3&theater

Olano and colleagues studied the ethnic, educational, and socioeconomic characteristics of participants in various mindfulness practices from the responses reported in the 2002, 2007, and 2012 National Health Interview Survey (NHIS). This survey included questions regarding participant characteristics and participation in various mindfulness practices.

They found that over 13% of the population participated in one or more mindfulness practices. Meditation and yoga were practiced about equally being engaged in by 7.6% and 7.5% of the population of the U.S. respectively, while tai chi and qigong were much less commonly practiced, 1.2% and 0.3% of the population respectively. Gender made a difference as men were half as likely as women to engage in any of the practices and more than three times less likely to practice yoga. Education level made a large difference with education beyond high school highly predictive of engagement in mindfulness practices. Race and ethnicity was also important with white and Asian Americans much more likely to practice than black or Hispanic Americans. Interestingly, income level only made a very slight difference in participation.

These results are very interesting as the characteristics of participants in mindfulness practices track health statistics for these groups. Low education level and being a member of a minority group are strong predictors of poor health outcomes and males live on average 7 years less than females. These results do not demonstrate that engagement in mindfulness practices are the sole reason for health disparities, as they are still present for non-practitioners. But, it is known that mindfulness practices promote good mental and physical health. So, the lack of practice in male, minority, and low education groups suggests that they are not taking advantage of the benefits of practice which may contribute to the health disparities.

These results strongly suggest that greater efforts should be made to bring mindfulness practices to these vulnerable populations and thereby improve health and well-being. The results of the current study suggest that income level is not a problem. This is important as it suggests that these practices can be spread at low relative cost. Given their very positive impacts on health, mindfulness practices would appear to be a very safe and cost effective means of improving health and addressing prevalent health disparities in the population.

“Researchers and clinicians who are interested in ethnic minority research in general and acceptance- and mindfulness-based treatments in particular must face the fact that ethnic minority psychologists are persistently underrepresented, despite different efforts having been made to promote the recruitment and retention of ethnic minority professionals in psychology.” – Janice Ka Yan Cheng

Healthy Aging – Improve the Brain and Memory with Tai Chi

Healthy Aging – Improve the Brain and Memory with Tai Chi

By John M. de Castro, Ph.D.

“Another great benefit of Tai Chi is that it’s accessible to people of all ages and fitness abilities. It’s the focus on the subtle movements that exercise the brain and boost cognitive abilities. First, it’s learning the precise movements of the ancient martial art form that will give your brain a boost. Then, it’s the continued focus linking the breath and the movements.” – Karl Romain

We all want to live longer. We celebrate the increasing longevity of the population. But, aging is a mixed blessing. The aging process involves a systematic progressive decline in every system in the body, the brain included. It cannot be avoided. Our mental abilities may also decline with age including impairments in memory, attention, and problem solving ability. These are called age related cognitive decline. This occurs to everyone as they age, but to varying degrees. Some deteriorate into a dementia, while others maintain high levels of cognitive capacity into very advanced ages. It is estimated that around 30% of the elderly show significant age related cognitive decline. But, remember that this also means that 70% of the elderly retain reasonable levels of cognitive ability. There is some hope, however, for those who are prone to deterioration as there is evidence that these cognitive declines can be slowed. For example, a healthy diet and a regular program of exercise can slow the physical decline of the body with aging. Also, 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.

Using modern neuroimaging techniques, scientists have been able to view the changes that occur in the nervous system with aging. In addition, they have been able to investigate various techniques that might slow the process of neurodegeneration that accompanies normal aging. They’ve 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.

There are some indications that physical and mental exercise can reduce the rate of cognitive decline and lower the chances of dementia. Tai Chi and Baduanjin are ancient eastern practices involving slow mindful movements. They are both a gentle exercise and a contemplative practice that improves mindfulness. Mindfulness practices have been shown to improve cognitive processes while Tai Chi practice has been shown to slow age related cognitive decline. It would seem reasonable to hypothesize that Tai Chi and Baduanjin practices might decrease age related cognitive decline and the associated changes in the nervous system.

Tao and colleagues investigated the effects of Tai Chi and Baduanjin practice on age related declines on memory and the neural systems involved in memory processes (Hippocampus and Medial Prefrontal Cortex). They randomly assigned 50-70 year-old participants to either Tai Chi practice, Baduanjin practice, or a no-practice control group. Both the Tai Chi and Baduanjin groups practiced one hour per day, 5-days per week, for 12 weeks.

They found that both Tai Chi and Baduanjin practice increased memory scores by about 25% while they were unchanged in the control group. They further found that both Tai Chi and Baduanjin practice increased the connectivity of the Hippocampus and Medial Prefrontal Cortex, indicating heightened communications between these memory related brain areas. In addition, the memory improvement was significantly positively associated with the increased connectivity, such that the greater the improvement in connectivity, the greater the improvement in memory. This is important in that it supports the conclusion that the changes in the brain are responsible for the improvements in memory.

It should be noted that the control group did not exercise. So, it cannot be determined if the improved memory and connectivity were due specifically to the mind-body aspects of Tai Chi and Baduanjin practices or due to the exercise provided by engaging in these gentle practices. It remains for future research to determine which aspect of the practices are responsible for the beneficial changes.

Regardless, the results are clear and exciting, Tai Chi and Baduanjin practice improves memory associated with improved connectivity between memory related brain areas in an aging population. In addition, Tai Chi and Baduanjin practices have the added benefit of being safe and gentle practices, with no known adverse effects. So, they are very appropriate for an aging population. Baduanjin practice does not involve the legs. So, it may be appropriate for aging groups who have difficulties with their hips, knees, ankles, fee, or legs. Finally, since they can be taught and practiced in groups and easily maintained at home, it is a very inexpensive intervention. This makes it almost ideal for aging individuals on fixed incomes.

So, improve the brain and memory with tai chi.

“Tai chi is often described as “meditation in motion,” but it might well be called “medication in motion.” There is growing evidence that this mind-body practice, which originated in China as a martial art, has value in treating or preventing many health problems. And you can get started even if you aren’t in top shape or the best of health.”– Harvard Women’s Health Watch

Frontiers in Aging Neuroscience, 8, 25. http://doi.org/10.3389/fnagi.2016.00025

Abstract

Previous studies provide evidence that aging is associated with the decline of memory function and alterations in the hippocampal (HPC) function, including functional connectivity to the medial prefrontal cortex (mPFC). In this study, we investigated if longitudinal (12-week) Tai Chi Chuan and Baduanjin practice can improve memory function and modulate HPC resting-state functional connectivity (rs-FC). Memory function measurements and resting-state functional magnetic resonance imaging (rs-fMRI) were applied at the beginning and the end of the experiment. The results showed that (1) the memory quotient (MQ) measured by the Wechsler Memory Scale-Chinese Revision significantly increased after Tai Chi Chuan and Baduanjin practice as compared with the control group, and no significant difference was observed in MQ between the Tai Chi Chuan and Baduanjin groups; (2) rs-FC between the bilateral hippocampus and mPFC significantly increased in the Tai Chi Chuan group compared to the control group (also in the Baduanjin group compared to the control group, albeit at a lower threshold), and no significant difference between the Tai Chi Chuan and Baduanjin groups was observed; (3) rs-FC increases between the bilateral hippocampus and mPFC were significantly associated with corresponding memory function improvement across all subjects. Similar results were observed using the left or right hippocampus as seeds. Our results suggest that both Tai Chi Chuan and Baduanjin may be effective exercises to prevent memory decline during aging.

Improve Arthritis with Massage, Yoga, and Tai Chi

“Osteoarthritis is a degenerative joint disease which can lead to pain and swelling of your joints. Yoga is a great complimentary practice to help overcome knee osteoarthritis relief, as you’re strengthening and loosening your joints, and improving your overall well being.” – Minakshi Welukar

Osteoarthritis is a chronic degenerative joint disease that is the most common form of arthritis. It produces pain, swelling, and stiffness of the joints. It is the leading cause of disability in the U.S., with about 43% of arthritis sufferers limited in mobility and about a third having limitations that affect their ability to perform their work. In the U.S., osteoarthritis affects 14% of adults over 25 years of age and 34% of those over 65. Knee osteoarthritis is not localized to the cartilage alone but involves the whole joint, including articular cartilage, meniscus, ligament, and peri-articular muscle. It is painful and disabling. While age is a major risk factor for osteoarthritis of the knee, young people are not immune. It effects 5% of adults over 25 years of age and 12% of those over 65. Its causes are varied including, hereditary, injury including sports injuries, repetitive stress injuries, infection, or from being overweight. There are no cures for knee osteoarthritis. Treatments are primarily symptomatic, including weight loss, exercise, braces, pain relievers and anti-inflammatory drugs, corticosteroids, arthroscopic knee surgery, or even knee replacement.

Gentle movements of the joints with exercise appears to be helpful in the treatment of knee osteoarthritis. This suggests that alternative and complementary practices that involve gentle knee movements may be useful in for treatment. Indeed, yoga practice has been shown to be effective in treating arthritis and mind-body practices in general have been shown to reduce the gene expressions that underlie the inflammatory response which contribute to arthritis. So, it would seem reasonable to look further into the effectiveness of alternative and complementary practices in treating knee osteoarthritis.

Or see below

Tiffany Field reviews the literature on the application of three alternative and complementary practices, massage therapy, yoga, and tai chi, for the treatment of treating knee osteoarthritis. She reports that the literature finds fairly consistently that massage can help to relieve pain. It appears that pressure massage, involving skin displacement if more effective than light massage. She further reports that yoga practice has been routinely found to reduce pain and relieve accompanying depression and sleep problems in arthritis sufferers. Yoga practice appears to produce better results than simple light exercise. Finally, she reports that the ancient Chinese gentle slow movement practice of Tai Chi significantly decreased knee pain and improved movement characteristics including stride length, stride frequency and gait speed.

The results of the reviewed studies are encouraging that massage therapy, and yoga and tai chi practices are effective in treating knee osteoarthritis. Yoga and tai chi have other characteristics that recommend them. They are both safe practices with very few, if any, adverse effects and importantly, they both can be practiced conveniently and inexpensively in groups or alone at home, thus allowing their widespread affordable application to sufferers. In addition, both yoga and tai chi practices have been shown to have a large number of other physical and psychological benefits. So, they would seem to be excellent alternative and complementary practices for the treatment of knee osteoarthritis.

So, improve arthritis with massage, yoga, and tai chi.

Highlights

Massage therapy reduces knee osteoarthritis pain in the elderly.
Yoga reduces knee osteoarthritis pain in the elderly.
Tai chi reduces knee osteoarthritis pain in the elderly.

Abstract

Background and methods: This is a review of recently published research, both empirical studies and meta-analyses, on the effects of complementary therapies including massage therapy, yoga and tai chi on pain associated with knee osteoarthritis in the elderly.

Results: The massage therapy protocols have been effective in not only reducing pain but also in increasing range of motion, specifically when moderate pressure massage was used and when both the quadriceps and hamstrings were massaged. The yoga studies typically measured pain by the WOMAC. Most of those studies showed a clinically significant reduction in pain, especially the research that focused on poses (e.g. the Iyengar studies) as opposed to those that had integrated protocols (poses, breathing and meditation exercises). The tai chi studies also assessed pain by self-report on the WOMAC and showed significant reductions in pain. The tai chi studies were difficult to compare because of their highly variable protocols in terms of the frequency and duration of treatment.

Discussion: Larger, randomized control trials are needed on each of these therapies using more standardized protocols and more objective variables in addition to the self-reported WOMAC pain scale, for example, range-of-motion and observed range-of-motion pain. In addition, treatment comparison studies should be conducted so, for example, if the lower-cost yoga and tai chi were as effective as massage therapy, they might be used in combination with or as supplemental to massage therapy. Nonetheless, these therapies are at least reducing pain in knee osteoarthritis and they do not seem to have side effects.

Promote Physical and Mental Well-Being with Tai Chi

“Tai Chi exercise had positive effects on the self-assessed physical and mental health of college students. Scores on the mental health dimension appeared to be particularly sensitive to change. Colleges/universities might consider offering Tai Chi as a component of their ongoing physical activity programs available to students.” – Y. T. Wang

Many people have fond memories of their college years. It is likely, however, that they forgot about the stress and angst of those years. The truth is that college is generally very stressful for most students, from the uncertainty of freshman year, to the social stresses of emerging adulthood, to the anxiety of launching into a career after senior year. Evidence for the difficulties of these years can be found in college counseling centers which are swamped with troubled students. In fact, it’s been estimated that half of all college students report significant levels of anxiety and depression.

Being able to perform at an optimum level is important in college. It would be very helpful if a

safe and effective way could be found to reduce stress, depression and anxiety in college students. Mindfulness training has been shown to reduce anxiety, stress, and depression . So, mindfulness training would appear to be well suited to deal with the problems of college students. The ancient eastern practice of mindful movement Tai Chi has been shown to reduce stress, depression, and anxiety. Hence, it would make sense to investigate whether Tai Chi practice might be effective for improving college student angst.

In today’s Research News article “A systematic review of the health benefits of Tai Chi for students in higher education”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1180406471983277/?type=3&theater

Webster and colleagues review the published literature on the effectiveness of Tai Chi practice in improving college student physical and psychological states. They found that that the preponderance of evidence in the literature reported that Tai Chi practice significantly improved muscular flexibility. But the most interesting effects were in the psychological domain with Tai Chi practice significantly reducing depression, anxiety, symptoms of compulsion, somatization symptoms, hostility, and symptoms of phobia, and improved interpersonal sensitivity.

Hence, the published scientific literature suggests that Tai Chi practice can be of significant benefit for college students, improving them physically and improving their psychological well-being. Tai Chi practice is a gentle mindful movement practice. It is safe, having few if any adverse consequences, and effective with college students. This suggests that the engagement in Tai Chi practice should be encouraged in college promoting the physical and mental well-being of the students.

“Of all the exercises, I should say that T’ai Chi is the best. It can ward off disease, banish worry and tension, bring improved physical health and prolong life. It is a good hobby for your whole life, the older you are, the better. It is suitable for everyone – the weak, the sick, the aged, children, the disabled and blind. It is also an economical exercise. As long as one has three square feet of space, one can take a trip to paradise and stay there to enjoy life for thirty minutes without spending a single cent.” ~T.T. Liang

Improve Physical and Cognitive Function with Tai Chi

March 5, 2016 psyjdc 19 Comments

By John M. de Castro, Ph.D.

“Because Tai Chi may impact cognitive function via a diverse and potentially synergistic set of mechanistic pathways, it is plausible that it may offer benefits superior to interventions that target only single pathways (e.g., aerobic training or stress reduction alone)” – Peter Wayne

The process of aging affects every aspect of the physical and cognitive domains. Every system in the body deteriorates including motor function with a decline in strength, flexibility, and balance. Impaired balance is a particular problem as it can lead to falls. In the U.S. one third of people over 65 fall each year and 2.5 million are treated in emergency rooms for injuries produced by falls. About 1% of falls result in deaths making it the leading cause of death due to injury among the elderly. It is obviously important to investigate methods to improve balance and decrease the number of fall in the elderly.

Perhaps more troubling than the physical decline is the mental deterioration that occurs with aging. This is called age related cognitive decline and includes decreases in memory, attention, and problem solving ability. This occurs to everyone as they age, but to varying degrees. Some deteriorate into a dementia, while others maintain high levels of cognitive capacity into very advanced ages. It is estimated that around 30% of the elderly show significant age related cognitive decline. But, remember that this also means that 70% of the elderly retain reasonable levels of cognitive ability.

It is, therefore, important to investigate methods to slow the mental decline during aging. Some promising methods are contemplative practices which have been shown to restrain age related declines. One particularly promising method is the ancient eastern practice of Tai Chi. It is particularly promising due to the fact that it is both a physical and a mental practice. Indeed, tai chi practice has been shown to slow cognitive decline in aging.

In today’s Research News article “Effects of Tai Chi and Western Exercise on Physical and Cognitive Functioning in Healthy Community-Dwelling Older Adults”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1177689028921688/?type=3&theater

Taylor-Piliae and colleagues randomly assigned sedentary adults over 60 years of age to either a tai chi practice, a physical exercise program, or attention (healthy aging) training. Training occurred twice a week in 90-minute classes and three times per week in home practices. They measured the physical and mental capabilities of the participants at 6 and 12 months of training. They found that both the tai chi and exercise groups improved in both flexibility and balance in comparison to the control condition. At 6 months the tai chi group was superior with balance while the exercise group was superior in flexibility, but at 12 months the two groups were equivalently superior to the control group in both flexibility and balance. In contrast, only the tai chi group demonstrated improved levels of cognitive function including memory and semantic fluency at both 6 and 12 months.

These results suggest that both tai chi and exercise are effective in slowing the physical decline with aging but tai chi has the added benefit of also slowing the cognitive decline. Since tai chi is safe, with no known adverse effects, and a gentle practice it is very appropriate for an aging population. Also, since it can be taught and practiced in groups and easily maintained at home, it is a very inexpensive intervention. This makes it almost ideal for aging individuals on fixed incomes.

The results suggest that tai chi practice may be helpful in preventing falls as a result of improvement in balance and flexibility and slow the mental decline with aging. This indicates that tai chi practice should be recommended for elderly individuals to help maintain their physical and mental abilities. So, improve physical and cognitive function with tai chi.

Age Healthily: Improve Cellular Health with Mindfulness

“Simply responding to the physical symptoms of disease might make sense for treating an acute infection or fixing a broken leg, but to beat chronic age-related conditions such as diabetes, heart disease and dementia, we will need to embrace the fuzzy, subjective domain of the mind.” – Jo Marchant

Aging seems inevitable. But, different species age at different rates. Everyone knows for example that dogs’ life span is about 1/6^th of the human life span. This suggests that there must be some biological mechanism that regulates aging. Recent genetic research is starting to uncover that mechanism. It has been found that the genes, coded on the DNA molecule, govern cellular processes in our bodies. One of the most fundamental of these processes is cell replication. Cells are constantly turning over. Dying cells or damaged are replaced by new cells. The cells turn over at different rates but most cells in the body are lost and replaced between every few days to every few months. Needless to say were constantly renewing ourselves.

As we age the tail of the DNA molecule called the telomere shortens. When it gets very short cells have a more and more difficult time reproducing and become more likely to produce defective cells. On a cellular basis this is what produces aging. As we get older the new cells produced are more and more defective. The shortening of the telomere occurs each time the cell is replaced. So, slowly as we age it gets shorter and shorter. This has been called a “mitotic clock.” This is normal. But, telomere shortening can also be produced by oxidative stress, which can be produced by psychological and physiological stress. This is mediated by stress hormones and the inflammatory response. So, chronic stress can accelerate the aging process. In other words, when we’re chronically stressed we get older faster.

Fortunately, there is a mechanism to protect the telomere. There is an enzyme in the body called telomerase that helps to prevent shortening of the telomere. It also promotes cell survival and enhances stress-resistance. Research suggests that processes that increase telomerase activity tend to slow the aging process by protecting the telomere. One activity that seems to increase telomerase activity and protect telomere length is mindfulness practice (see http://contemplative-studies.org/wp/index.php/2015/12/04/retreat-for-longevity/ and http://contemplative-studies.org/wp/index.php/2015/07/17/aging-healthily-yoga-and-cellular-aging/). Hence, engaging in mindfulness practices may protect the telomere and thereby slow the aging process.

In today’s Research News article “Telomerase activity and its association with psychological stress, mental disorders, lifestyle factors and interventions: A systematic review”

Deng and colleagues review the published scientific literature on factors that influence telomerase activity. They report that chronic, long-term, psychological stress but not acute, short-term, stress reduced telomerase activity. They also report that Major Depressive Disorder is associated with reduced telomerase activity. Importantly, they find that diet, exercise, and mindfulness practices all increase telomerase activity. In particular, they found that “physical exercise, diet micronutrient supplementation, mindfulness meditation, Qigong practice or yoga mediation resulted in increase in telomerase activity.”

These are very exciting outcomes and suggest that mindfulness practices might contribute to longevity by reducing cellular aging. How might these very different practices increase telomerase activity? All of these mindfulness practices have been shown to reduce the psychological and physiological responses to stress (see http://contemplative-studies.org/wp/index.php/category/research-news/stress/). Since, chronic stress has been shown to reduce telomerase activity and in turn accelerate cellular aging, it would seem reasonable to conclude that practices that reduce stress responses would protect the individual from the deleterious effects of stress and increase telomerase activity. There may be other mechanisms involved, but this would seem to be the obvious one.

These findings suggest that mindfulness practices may improve longevity by protecting us from the damaging effects of chronic stress. By making us more mellow, we age slower.

So, age healthily: improve cellular health with mindfulness.

“it is possible that greater presence of mind promotes a healthy biochemical milieu and, in turn, cell longevity,” – Elizabeth Blackburn

Reduce Fatigue in Cancer treatment with Tai Chi

February 17, 2016 psyjdc 1 Comment

“If you’re fighting cancer, chances are you’re also fighting fatigue. Fatigue is being tired – physically, mentally, and emotionally. It’s the most common side effect of cancer treatment, and it often hits without warning. Everyday activities – talking on the phone, shopping for groceries, even lifting a fork to eat – can be overwhelming tasks.” – American Cancer Society

Fatigue accompanies cancer and its treatment in from half to all cancer patients depending upon the type of cancer and treatment regimen. The fatigue can continue even after completion of successful treatment. The patient feels weak, tired, weary, or exhausted all of the time and sleep does not relieve the tiredness. Symptoms can include prolonged, extreme tiredness following an activity, arms and legs feeling heavy and hard to move, lack of engagement in normal daily activities, trouble concentrating, thinking clearly, or remembering, feeling frustrated, irritable, and upset, putting less energy into personal appearance, and spending more time in bed or sleeping. The cause of cancer-related fatigue is unknown.

It is easy to confuse cancer-related fatigue with depression. Both are subjective experiences and have many common symptoms. The one distinguishing feature is that in depression the individual is unable to experience pleasure and feels sad or unworthy, while this is generally not true regarding cancer patients. Nonetheless, it is very difficult to distinguish the fatigue from depression. The best treatment for cancer-related fatigue appears to be encouragement to engage in moderate exercise along with relaxation and body awareness training. The ancient Chinese practice of Tai Chi has all of these properties. It’s a light exercise that produces relaxation and body awareness. So, it would seem reasonable to expect that Tai Chi practice would be effective in treating cancer-related fatigue. Indeed, Tai Chi has been shown to improve the immune system and reduce inflammation in cancer (see http://contemplative-studies.org/wp/index.php/2016/01/14/kill-cancer-with-tai-chi/).

In today’s Research News article “Tai Chi Exercise for Cancer Related Fatigue in Patients with Lung Cancer Undergoing Chemotherapy: A Randomized Controlled Trial”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1167329929957598/?type=3&theater

Zhang and colleagues randomly assigned lung cancer patients undergoing chemotherapy to either a Tai Chi or low-impact exercise program practiced every other day for one hour during the course of chemotherapy treatment. They found that during treatment overall fatigue increased in both groups, but the Tai Chi group showed a significantly smaller increase than the low-impact exercise group. The Tai Chi treatment decreased general and physical fatigue and increased vigor. These results were found both 6 and 12 weeks after treatment.

These results are especially significant because of the nature of the trial wherein Tai Chi exercise was compared to another comparable active physical exercise. The fact that Tai Chi was superior to low-impact exercise implies that Tai Chi has particular properties beyond its exercise property that are important for the relief of cancer-related fatigue. It is possible that the concentration and mindfulness components of Tai Chi practice are important for its effectiveness. Indeed, mindfulness programs in general have been shown to be effective in cancer treatment (see http://contemplative-studies.org/wp/index.php/category/research-news/cancer/). It remains for future research to further determine what are the crucial aspects of Tai Chi practice that counteract cancer-related fatigue.

Regardless of the mechanism it is clear that engagement in Tai Chi practice is an effective treatment for cancer-related fatigue in lung cancer patients undergoing chemotherapy. Future research should attempt to extend these findings to other forms of cancer and other stages of treatment and recovery.

So, reduce fatigue in cancer treatment with tai chi.

“Research unequivocally shows that Tai Chi helps cancer patients through a variety of ways. One point to remember, though, is that regular exercise is paramount for maximal, sustained benefits. For cancer patients to receive the best results possible, therefore, it is advisable that people embrace Tai Chi as a way of life and not a one-time thing.” Willian Betts

Mindfully Control Inflammation

January 30, 2016April 29, 2022 psyjdc 2 Comments

“I don’t think anybody would argue that fact that we know inflammation in the body, which comes from a lot of different sources, is the basis for a lot of chronic health problems, so by controlling that, we would expect to see increased life expectancy … but if we’re not changing those things and just taking ibuprofen, I don’t know if we’re really going to make any headway in that, I feel like there are probably a lot of factors that we could change without medicating with risk.”– Josie Znidarsic

The immune system is designed to protect the body from threats like stress, infection, injury, and toxic chemicals. One of its tools is the Inflammatory response. Its primary effect is to increase blood circulation around the infected area, dilating the blood vessels around the site of inflammation. It also produces gaps in the cell walls surrounding the infected area, allowing the larger immune cells, to pass. It also tends to increase body temperature to further fight infection. This response works quite well for short-term infections and injuries and as such is an important defense mechanism for the body. But when inflammation is protracted and becomes chronic, it can itself become a threat to health.

Chronic inflammation can produce autoimmune diseases such as colitis, Chron’s disease, arthritis, heart disease, increased cancer risk, lung disease, sleep disruption, gum disease, decreased bone health, psoriasis, and depression. Needless to say chronic inflammation can create major health problems. Indeed, the presence of chronic inflammation is associated with reduced longevity. So, it is important for health to control the inflammatory response, allowing it to do its job in fighting off infection but then reducing its activity when no external threat is apparent.

Contemplative practices appear to relax the physical systems of the body including the immune system, reducing inflammation. Mind-body techniques such as yoga, Tai Chi and meditation have been shown to adaptively reduce the inflammatory response (see http://contemplative-studies.org/wp/index.php/category/research-news/inflammatory-response/). In today’s Research News article “Mind-body therapies and control of inflammatory biology: A descriptive review”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1157023674321557/?type=3&theater

Bower and colleagues review the published research literature on the effects of mind-body practices on the inflammatory response. They found mixed and inconclusive results for circulating and cellular markers of inflammation but consistent findings for gene expression inflammatory pathways. These studies consistently demonstrated that mind-body practices including tai chi, yoga, and meditation produced a decrease in inflammatory gene expressions and does so in diverse populations of practitioners.

Bower and colleagues suggest that mind-body practices alter gene expression through their well-documented effects on the neuroendocrine system. These techniques are known to reduce the activity of the activating portion of the peripheral nervous system, the sympathetic system, to reduce the release of stress hormones, particularly cortisol, and to lower perceived stress (see http://contemplative-studies.org/wp/index.php/category/research-news/stress/). Mind-body practices are also known to improve emotion regulation (see http://contemplative-studies.org/wp/index.php/category/research-news/emotions/) and reduce depression (see http://contemplative-studies.org/wp/index.php/category/research-news/depression/), and anxiety (see http://contemplative-studies.org/wp/index.php/2016/01/02/distress-produces-less-stress-with-mindfulness/). All of these effects occur via alterations of the nervous system by mind-body practices. The reduced activation and heightened relaxation then reduce the inflammatory response.

Regardless of the explanation, it is clear that mindfulness practices reduce potentially harmful inflammatory responses. So, mindfully control inflammation.

“The mindfulness-based approach to stress reduction may offer a lower-cost alternative or complement to standard treatment, and it can be practiced easily by patients in their own homes, whenever they need.” – Melissa Rosenkranz

Kill Cancer with Tai Chi

January 14, 2016 psyjdc 2 Comments

“Tai chi is often described as “meditation in motion,” but it might well be called “medication in motion.” There is growing evidence that this mind-body practice… has value in treating or preventing many health problems.” ~Harvard Women’s Health Watch

Our bodies contain many cancerous cells. They usually don’t develop into a cancer as our bodies defenses keep them under control. Part of that defense are types of peripheral blood mononuclear cells called Natural Killer (NK) cells. These are fast acting white blood cells that can destroy virus containing or tumor cells. So, in fighting off the development of cancerous cells into a deadly cancer, the NK cells are an important early component.

Exercise is known to increase NK cells in cancer survivors. Tai Chi is a gentle exercise that has been practiced for thousands of years with purported benefits for health and longevity. Tai Chi training is designed to enhance function and regulate the functional activities of the body through regulated breathing, mindful concentration, and gentle movements. Only recently though have the effects of Tai Chi practice been scrutinized with empirical research. It has been found to be effective for an array of physical and psychological issues See links below). One of the ways that it acts to have these effects is by strengthening immune system function (see http://contemplative-studies.org/wp/index.php/2015/10/30/strengthen-the-immune-system-with-qigong/). It has also been shown to improve recovery from cancer (see http://contemplative-studies.org/wp/index.php/2015/07/17/age-healthily-mindful-movement-and-cancer-recovery/).

Lung cancer is the leading cancer killer in both men and women in the U.S. Over 150,000 people a year in the U.S. die from lung cancer. If it is caught early about half of the patients will survive for at least 5 years. But, only about 15% of the cases are diagnosed early. So, overall only about 18% of the patients survive for at least 5 years. Needless to say treatments to improve survival with lung cancer are badly needed.

In today’s Research News article “Effect of Tai Chi on mononuclear cell functions in patients with non-small cell lung cancer”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1148256135198311/?type=3&theater

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4321705/

Liu and colleagues examine the effects of 16 weeks of Tai Chi exercise on peripheral blood mononuclear cells in lung cancer patients who had survived at least 2 years compared to a comparable treatment as usual group. Tai Chi produced a significant increase in the ability of peripheral blood mononuclear cells.to kill cancer cells. They found that the Natural Killer cells were the type of peripheral blood mononuclear cell that increased in the Tai Chi group.

These are potentially important results. They suggest that Tai Chi may be helpful in survival from lung cancer by improving the immune system’s ability to kill cancerous cells, particularly by increasing the levels of Natural Killer cells. Further research is needed to determine if this improves long-term survival in these patients.

There are a number of ways that Tai Chi may be improving the immune response to cancer. The simplest explanation is as an exercise. The advantage of Tai Chi, however, over other exercises is that it is very safe and gentle and can be practiced by people of all ages. Another possible explanation is that Tai Chi is known to improve the psychological and physiological response to stress. So, Tai Chi may be effective by improving the patients’ response to the stress of the illness. Regardless, it is clear that Tai Chi improves ability to kill cancer cells.

So, kill cancer with tai chi.
