Control Blood Pressure with Mindfulness

psyjdc 1 Comment

“A chronic state of arousal isn’t healthy. It causes hypertension, and it has been implicated in diabetes, asthma, and various gastrointestinal disorders. Part of the arousal response is to turn off the immune system, so you are breaking down instead of healing yourself.” ~ Erika Friedmann

 

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.  Hypertension is present in about 70% of first heart attacks, about 80% of first strokes, and about 70% of chronic heart failures. 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. Additionally, nearly a third of American adults have prehypertension, with blood pressure higher than normal, but not yet considered hypertension.

 

High blood pressure, because it doesn’t have any primary symptoms is usually only diagnosed by direct measurement of blood pressure usually by a health care professional. When hypertension is chronically present over three quarters of patients are treated with antihypertensive drugs. But these medications often have adverse side effects. So, patients feel lousy when taking the drugs, but fine when they’re not. So, compliance is a major issue with many patients not taking the drugs regularly or stopping entirely.

 

Obviously there is a need for alternative to drug treatments for hypertension. Stress is known to be a contributing factor to hypertension. It acts in part by increasing activity in the sympathetic nervous system, the activating component of the peripheral nervous system and by increasing the release of stress hormones. So controlling stress would appear to be a reasonable non-drug approach to reducing high blood pressure.

 

Mindfulness Based Stress Reduction (MBSR) programs were designed specifically to reduce stress. They include meditation, body scan, and yoga practices. Meditation (see http://contemplative-studies.org/wp/index.php/2015/08/21/control-blood-pressure-with-meditation/), and yoga (see http://contemplative-studies.org/wp/index.php/category/contemplative-practice/yoga-contemplative-practice/), and body scan (see http://contemplative-studies.org/wp/index.php/2015/07/29/get-your-calm-on/)  have  been shown to be successful in reducing both the psychological and physiological responses to stress. So, it would seem appropriate to use these techniques as alternatives to drug treatment for hypertension.

 

In today’s Research News article “Effect of Group Mindfulness-Based Stress-Reduction Program and Conscious Yoga on Lifestyle, Coping Strategies, and Systolic and Diastolic Blood Pressures in Patients with Hypertension”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1154248347932423/?type=3&theater

Nejati and colleagues compared hypertensive patients randomly assigned to receive an 8-week MBSR program or no treatment. They found significant positive improvements produced by MBSR treatment including improved lifestyle (nutrition, exercise, health responsibility, stress management, interpersonal support, and self-actualization), coping strategies (problem-focused and emotion-focused), and blood pressure (systolic and diastolic).

 

These results are impressive, but need to be tempered with the fact that the control condition was a no treatment condition. Without an active control many potentially confounding variables are present. But the results reinforce previous studies that make a compelling case that mindfulness practices such as MBSR are excellent alternatives to medication for the treatment of hypertension.

 

So, control blood pressure with mindfulness.

Improve Heart Disease with Mindfulness

psyjdc 1 Comment

“Think about it: Heart disease and diabetes, which account for more deaths in the U.S. and worldwide than everything else combined, are completely preventable by making comprehensive lifestyle changes. Without drugs or surgery.”- Dean Ornish

 

Cardiovascular disease is the number one killer, claiming more lives than all forms of cancer combined. “Heart disease is the leading cause of death for both men and women. About 610,000 people die of heart disease in the United States every year–that’s 1 in every 4 deaths. Every year about 735,000 Americans have a heart attack.” – Centers for Disease Control.

 

A myriad of treatments has been developed for heart disease including a variety of surgical procedures and medications. In addition, lifestyle changes have proved to be effective including quitting smoking, weight reduction, improved diet, physical activity, and reducing stresses. Contemplative practices, such as tai chi and yoga, have also been shown to be helpful for heart health (see http://contemplative-studies.org/wp/index.php/category/research-news/cardiovascular/). In addition, mindfulness practices have also been shown to be helpful for producing the kinds of other lifestyle changes needed such as smoking cessation, weight reduction, and stress reduction.

 

One problem with the employment of mindfulness treatment programs to treat disease is that they require patients to meet frequently with professional therapists in either individual or group settings. This can be inconvenient, costly, and time consuming. So, it would be very helpful if mindfulness based techniques could be successfully delivered over the internet. In today’s Research News article “Web-Based Mindfulness Intervention in Heart Disease: A Randomized Controlled Trial”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1149633058393952/?type=3&theater

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4671576/

Younge and colleagues test whether a web-based mindfulness training program can be successfully used for the treatment of cardiovascular disease. They compared a randomly assigned group of patients with heart disease undergoing usual medical care plus a 12-week on-line mindfulness training to a group only receiving usual care. The mindfulness training program included different meditations, self-reflection, yoga, and practical assignments and suggestions for using mindfulness in day-to-day life. They found that the mindfulness intervention group had significantly improved exercise capacity, compared to usual treatment, as measured with a 6-minute walking test of cardiovascular function. The improvements included decreased heart rate and blood pressure.

 

The fact that mindfulness improved exercise capacity is important as it is well known that a well-designed exercise program is fundamental to the treatment of heart disease. This combined with the proven ability of mindfulness training to help with the other lifestyle changes that are helpful for heart disease suggest that mindfulness training should be included in a heart disease treatment program. The fact that the mindfulness training was delivered over the internet is very important. This markedly improves the convenience, affordability, and availability of this treatment to patients.

 

So, improve heart disease with mindfulness.

Improve Physical Well-being with Bikram Yoga

Yoga Bikram Hewett2

“My system works, as long as people let me do my job my way. It is not just the sequence, it is how you do it: the timing, the mirrors, the temperature, the carpet. But if people only do it 99% right, it is 100% wrong. When someone tries to mess with it, the people won’t get the yoga benefits.” – Bikram Choudhury

 

Yoga practice has been shown to improve physical well-being (see http://contemplative-studies.org/wp/index.php/category/contemplative-practice/yoga-contemplative-practice/). But, there are a large number of different types of yoga practice including Ansura, Ashtanga, Bikram, Hatha, Hot Yoga, Iyengar, Jivamukti, Kripalu, Kundalini, Prenatal, Restorative, Viniypga, Vinyasa, and yin. One problem with the research on yoga effects is that different researchers use different types of yoga. So, it is difficult to compare results. In addition, the studies do not establish the relative effectiveness of each type of yoga.

 

Bikram Yoga is somewhat unique in that it employs a set sequence of 26 poses (asanas) and two breathing exercises. It is practiced in a heated environment (105°F, 40.6°C, 40% humidity) and there is a unique programmed instructional dialogue. The hot environment is thought to soften the muscles making them more pliable and loosen the joints making them more flexible allowing the practitioner to go deeper into poses. The sweating that occurs is thought to help remove toxins and impurities.

 

In today’s Research News article “The Effects of Bikram Yoga on Health: Critical Review and Clinical Trial Recommendations”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1137653292925262/?type=3&theater

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4609431/

Hewett and colleagues review the published research on the effectiveness of Bikram Yoga on physical well-being. They report that in terms of physical fitness, Bikram Yoga increases lower body range of motion, balance, isometric dead-lift strength, isometric maximal voluntary contraction, total hip bone density, and balance compared to the control group. It appears to improve cardiovascular fitness, increasing carotid artery compliance and decreasing beta-stiffness, and HDL and total cholesterol. In overweight and obese practitioners Bikram Yoga improved a number of metabolic markers including blood lipids, insulin resistance, and glucose tolerance. Psychologically, this form of yoga appears to reduce perceived stress and increase mindfulness.

 

These are important findings suggesting that Bikram Yoga is effective in improving fitness, cardiovascular, health, and psychological well-being. The reviewed research studies were limited and did not investigate many other physical and mental parameters and did not investigate Bikram Yoga’s applicability to the treatment of diseases. Unfortunately, the research studies reviewed did not compare Bikram Yoga to other forms of yoga, so it is not known what if any of the reported benefits are specific to Bikram Yoga and which are in common with other practices. This review is an important first step in documenting the effects of Bikram Yoga which are shown to be widely beneficial. It is clear that much more research is warranted comparing the effects of the different forms of practice.

 

Regardless, the results are clear that you can improve well-being with Bikram Yoga.

 

“To sweat is to pray, to make an offering of your innermost self. Sweat is holy water, prayer beads, pearls of liquid that release your past. Sweat is an ancient and universal form of self healing, whether done in the gym, the sauna, or the sweat lodge … The more you sweat, the more you pray. The more you pray, the closer you come to ecstasy.”  – Gabrielle Roth

Improve Mental and Physical Well-being with Yoga

Yoga cognition Nagendra2

“The breathing and meditative exercises aim at calming the mind and body and keeping distracting thoughts away while you focus on your body, posture or breath. Maybe these processes translate beyond yoga practice when you try to perform mental tasks or day-to-day activities.” – Neha Gothe

 

If we are lucky enough to navigate life’s dangers we are rewarded with the opportunity to experience aging! The aging process involves a progressive deterioration of the body including the brain. It actually begins in the late 20s and continues throughout the lifespan. It’s inevitable. We can’t stop it or reverse it. But, it is becoming more apparent that life-style changes can slow down and to some extent counteract the process and allow us to live longer and healthier lives. This is true for both physical and mental deterioration including degeneration and shrinkage of the nervous system. Aging healthily to a large extent involves strategies to slow down the deterioration.

 

Contemplative practices including yoga practice (See links below) have been shown to reduce the physical deterioration that occurs with aging (see http://contemplative-studies.org/wp/index.php/category/research-news/aging/). Yoga practice has many physical and mental benefits including protection of brain structures from degeneration with aging (see http://contemplative-studies.org/wp/index.php/2015/07/17/age-healthily-protect-the-brain-with-yoga/). These structural changes have been demonstrated by neuroimaging techniques with yoga practitioners. They document change in the size and connectivity of brain structures that result from yoga practice.

 

Yoga is a mind-body practice that involves both physical and mental exercises. This is accompanied by changes in the activity of virtually every component of the body including general physiology and the peripheral and central nervous systems. So, another potential method to investigate yoga’s effects on the nervous system is to measure the electrical signals emanating from the nervous system.

 

In today’s Research News article “Cognitive Behavior Evaluation Based on Physiological Parameters among Young Healthy Subjects with Yoga as Intervention”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1136173913073200/?type=3&theater

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4339827/

Nagendra and colleagues trained naive adults in yoga practice for a period of five months for 1.5 hours per day and compared physiological measure to a no-treatment control group. They found that yoga practice produced an increase in parasympathetic (vegetative) and decrease in sympathetic (activation) activity in the peripheral nervous system including a decrease in heart rate and heart rate variability. This indicates a calming and relaxing effect of yoga on the physiology.

 

Nagendra and colleagues also found significant differences in EEG activity of the central nervous system. The changes were complex and varied. But they are indicators that yoga practice produces alterations of brain activity in ways that are indicative of improved vigilance, alertness, attention, concentration ,memory, visual information processing, sense of wellbeing, responsiveness, emotion process, cognition, and executive function and reduced stress and strain. In other words the changes in the brain activity indicated vast improvements in mental processing produced by yoga practice.

 

It should be noted that these are indirect measures and the researchers did not directly measure the psychological variables. So, although suggestive they are not conclusive. They are, however, similar to findings of yoga effects in other research with direct measures (see http://contemplative-studies.org/wp/index.php/category/contemplative-practice/yoga-contemplative-practice/). But, even with this caution, the results suggest that yoga practice has widespread beneficial effects on the mental and physical well-being of the individual.

 

So, practice yoga and improve mental and physical well-being.

 

“True yoga is not about the shape of your body, but the shape of your life. Yoga is not to be performed; yoga is to be lived. Yoga doesn’t care about what you have been; yoga cares about the person you are becoming. Yoga is designed for a vast and profound purpose, and for it to be truly called yoga, its essence must be embodied.” — Aadil Palkhivala

Heart Health with Tai Chi

“If you want to be healthy and live to one hundred, do qigong.” ~Mehmet Oz

Tai Chi and Qigong are ancient practices of mindful movement. The reason that they have continued to be practiced by millions for centuries is that they have major mental and physical benefits. Modern research is verifying these benefits. Mindful movement practice has been shown to improve balance, self-concept, and attention span, reduce falls, boost the immune system and helps to relieve symptoms of arthritis, asthma, Parkinson’s disease and insomnia. It has been shown to improve sleep in the elderly http://contemplative-studies.org/wp/index.php/2015/07/17/aging-healthily-sleeping-better-with-mindful-movement-practice/ and even improve cancer recovery http://contemplative-studies.org/wp/index.php/2015/07/17/age-healthily-mindful-movement-and-cancer-recovery/.

Tai Chi involves slow motion smooth mindful movements. It doesn’t look much like an exercise and so it has the reputation of not being an exercise that improves cardiovascular health. Tai chi “does not supply the cardiovascular component that we’d be looking for in a well-rounded routine. The exertion level, while challenging, is not going to increase your heart rate.” – Jessica Matthews. This notion, however, turns out to be untrue.

In today’s Research News article “The Effect of Tai Chi Training on Cardiorespiratory Fitness in Healthy Adults: A Systematic Review and Meta-Analysis.”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1081496985207560/?type=1&theater

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4332633/

Zheng and colleagues reviewed the literature on the effects of Tai Chi practice on heart and circulatory health in healthy adults. They find that there is considerable evidence that Tai Chi has positive effects on heart and circulatory health.

Tai Chi practice appears to improve blood pressure, heart stroke volume, resting heart rate, cardiac output, lung capacity, and heart and breathing endurance. It appears to do this without any adverse effects. This is remarkable, as all of the drugs used to produce these same effects have major side effects and adverse consequences. Hence, Tai Chi appears to be a safe and effective practice for heart and respiratory health.

So, practice Tai Chi and help maintain heart health.

“Tai chi does not mean oriental wisdom or something exotic. It is the wisdom of your own senses, your own mind and body together as one process.” ~Chungliang Al Huang

Improve Physical Health with Yoga

Yoga is an ancient practice. Its longevity would suggest that it has observable benefits for its practitioners. Although for years anecdotal evidence supported this notion, it has only recently been demonstrated with modern controlled research studies that yoga indeed is beneficial for health and well-being.

In a previous post, yoga practice was shown to reduce the symptoms of the Metabolic Syndrome a major risk factor for cardiovascular disease.

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1045854842105108/?type=1&theater

http://contemplative-studies.org/wp/index.php/2015/07/17/heart-healthy-yoga/

In another previous post, it was demonstrated the yoga practice improves the immune system

and in yet another post, yoga was shown to delay the decline in strength and flexibility on ageing individuals.

In today’s Research News article “Effects of a 12-Week Hatha Yoga Intervention on Cardiorespiratory Endurance, Muscular Strength and Endurance, and Flexibility in Hong Kong Chinese Adults: A Controlled Clinical Trial.”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1066686320021960/?type=1&theater

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4475706/

Lau and colleagues demonstrate that yoga improves cardiorespiratory endurance, muscular strength and endurance, and flexibility in both male and female adults.

One of the keys to any program for physical health is its acceptability. There are a large number of different varieties of fitness programs all of which can improve health if practiced. But many are disliked by participants who discontinue participation or only sporadically engage in the program. Lau and colleagues found that that people like yoga practice and so stick with it. Participants attended 94% of the available classes and only 11% dropped out. A practice is only as good a people’s willingness to engage in it and yoga practice appears to pass this test, making it a very good choice for physical health.

The fact that yoga is often practiced in groups may account, in part, for its enjoyability and the high participation rates. The presence of others provides support and camaraderie. The participant discussions that can precede and follow the practice can be helpful in learning about the progressions and difficulties encountered by others, making one’s own difficulties seem more normal and acceptable and setting more realistic expectations for future progress.

It would be expected that yoga would improve muscular strength and flexibility. After all that is what it’s designed to do. But the improvement in cardiovascular endurance is an important bonus. Cardiovascular disease is the number one cause of death in the U.S. killing 800,000 people each year. The observed improvement in cardiorespiratory endurance along with the prior findings of effectiveness for metabolic syndrome, suggest that yoga could help prevent cardiovascular disease and increase longevity.

So, practice the enjoyable exercise of yoga and improve your health.

Heart Healthy Yoga

Metabolic Syndrome is a major risk factor for cardiovascular disease and diabetes. It generally results from overweight and abdominal obesity and includes high blood pressure, insulin resistance and elevation of plasma cholesterol and triglycerides. It is an important risk factor as it increases the risk of developing type-2 diabetes five-fold and heart attack or stroke three-fold.

Metabolic Syndrome incidence has been rising rapidly approaching epidemic proportions. It is estimated that it currently affects 34% of US adults. Needless to say this is a major health problem. The good news is that timely treatment can prevent or reverse the risk. The simplest treatment is simply exercise and weight loss.

Yoga has been used to promote health and well-being for thousands of years. In today’s Research News article “Effects of 1-year yoga on cardiovascular risk factors in middle-aged and older adults with metabolic syndrome: a randomized trial”

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1045854842105108/?type=1&theater

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4440276/

Siu and colleagues examine whether yoga is an effective treatment for metabolic syndrome. They found that a 1-year yoga program reduced waist circumference, blood pressure, and resting heart rate and increased activity levels. This suggests that yoga is effective in reducing the symptoms of the Metabolic Syndrome.

Probably the most important finding was a 3.5% reduction in waist circumference. Most of the Symptoms of the Metabolic Syndrome result from a high level of abdominal fat. This produces the insulin resistance which in turn increases diabetes risk and raises cholesterol and triglycerides which increases cardiovascular risk. Hence, a key to treatment is to reduce this belly fat and yoga appears to be effective at doing just that.

Yoga is in part an exercise and this by itself could be responsible for the improvement. Indeed yoga practice increased activity levels which promotes the conversion of fat to muscle. So, even if there is no change in weight there is a reduction in abdominal fat, the primary culprit in Metabolic Syndrome.

Yoga, however, produces other beneficial effects that could be responsible for the improvement in Metabolic Syndrome. Yoga practice reduces the physiological symptoms of stress. It reduces the levels of stress hormones and it relaxes the sympathetic nervous system, the fight or flight system. Stress exacerbates the symptoms of Metabolic Syndrome. By reducing the physiological mechanisms by which stress affects Metabolic Syndrome, yoga can markedly improve the symptoms. In addition, by reducing stress, yoga can improve immune system response, increasing the individual’s ability to fight off diseases.

So practice yoga and reduce your risk of cardiovascular disease or diabetes.
