Improve Low Back Pain and Its Effects with Yoga Practice

 

By John M. de Castro, Ph.D.

 

“If you’re dealing with back pain, yoga may be just what the doctor ordered. Yoga is a mind-body therapy that’s often recommended to treat not only back pain but the stress that accompanies it. The appropriate poses can relax and strengthen your body.” – Emily Cronkleton

 

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

 

Obviously, there is a need for safe and effective treatments for low back pain that are low cost and don’t have troublesome side effects. Mindfulness practices are effective in treating pain and have been shown to be safe and effective in the management of low back pain. Yoga practice combines mindfulness practice with exercise and has been shown to have a myriad of health benefits. Many forms of yoga focus on the proper alignment of the spine, which could directly address the source of back and neck pain for many individuals. Indeed, yoga has been shown to relieve chronic pain. Yoga practice has also been shown to be effective for the relief of chronic low-back pain. The research has been accumulating and it is useful to summarize what has been learned.

 

In today’s Research News article “Yoga compared to non-exercise or physical therapy exercise on pain, disability, and quality of life for patients with chronic low back pain: 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/PMC7462307/ ) Zhu and colleagues review, summarize, and perform a meta-analysis of the effectiveness of yoga practice in comparison to other exercises for low back pain. They identified 18 randomized controlled trials.

 

They report that the published research found that yoga practice, in comparison to baseline and no-exercise controls, produced significant reductions in pain and functional disability that was still present 6 months after the completion of training. At 12 months, there was still a significant difference in functional disability but not pain. In comparison to physical therapy, yoga produced significantly greater pain reduction but not functional disability immediately after treatment but this difference disappeared at 4 weeks after the completion of training. Yoga practice did not produce significant improvements in the patients’ quality of life.

 

These results suggest that yoga practice is effective in improving pain and functional disability in patients with low back pain. Yoga practice appears to be as effective but not superior to physical therapy. Hence, the published research to date suggests that low back pain can be successfully treated with either yoga practice or physical therapy.

 

So, improve low back pain and its effects with yoga practice.

 

“Achy back? Give yoga a go. Numerous studies have shown the power of the ancient practice, which emphasizes stretching, strength, and flexibility, to relieve back soreness and improve function.” – Annie Houser

Study Summary

 

Feilong Zhu, Ming Zhang, Dan Wang, Qianqin Hong, Cheng Zeng, Wei Che. Yoga compared to non-exercise or physical therapy exercise on pain, disability, and quality of life for patients with chronic low back pain: A systematic review and meta-analysis of randomized controlled trials. PLoS One. 2020; 15(9): e0238544. Published online 2020 Sep 1. doi: 10.1371/journal.pone.0238544

 

Abstract

Background

Chronic low back pain (CLBP) is a common and often disabling musculoskeletal condition. Yoga has been proven to be an effective therapy for chronic low back pain. However, there are still controversies about the effects of yoga at different follow-up periods and compared with other physical therapy exercises.

Objective

To critically compare the effects of yoga for patients with chronic low back pain on pain, disability, quality of life with non-exercise (e.g. usual care, education), physical therapy exercise.

Methods

This study was registered in PROSPERO, and the registration number was CRD42020159865. Randomized controlled trials (RCTs) of online databases included PubMed, Web of Science, Cochrane Central Register of Controlled Trials, Embase which evaluated effects of yoga for patients with chronic low back pain on pain, disability, and quality of life were searched from inception time to November 1, 2019. Studies were eligible if they assessed at least one important outcome, namely pain, back-specific disability, quality of life. The Cochrane risk of bias tool was used to assess the methodological quality of included randomized controlled trials. The continuous outcomes were analyzed by calculating the mean difference (MD) or standardized mean difference (SMD) with 95% confidence intervals (CI) according to whether combining outcomes measured on different scales or not.

Results

A total of 18 randomized controlled trials were included in this meta-analysis. Yoga could significantly reduce pain at 4 to 8 weeks (MD = -0.83, 95% CI = -1.19 to -0.48, p<0.00001, I2 = 0%), 3 months (MD = -0.43, 95% CI = -0.64 to -0.23, p<0.0001, I2 = 0%), 6 to 7 months (MD = -0.56, 95% CI = -1.02 to -0.11, p = 0.02, I2 = 50%), and was not significant in 12 months (MD = -0.52, 95% CI = -1.64 to 0.59, p = 0.36, I2 = 87%) compared with non-exercise. Yoga was better than non-exercise on disability at 4 to 8 weeks (SMD = -0.30, 95% CI = -0.51 to -0.10, p = 0.003, I2 = 0%), 3 months (SMD = -0.31, 95% CI = -0.45 to -0.18, p<0.00001, I2 = 30%), 6 months (SMD = -0.38, 95% CI = -0.53 to -0.23, p<0.00001, I2 = 0%), 12 months (SMD = -0.33, 95% CI = -0.54 to -0.12, p = 0.002, I2 = 9%). There was no significant difference on pain, disability compared with physical therapy exercise group. Furthermore, it suggested that there was a non-significant difference on physical and mental quality of life between yoga and any other interventions.

Conclusion

This meta-analysis provided evidence from very low to moderate investigating the effectiveness of yoga for chronic low back pain patients at different time points. Yoga might decrease pain from short term to intermediate term and improve functional disability status from short term to long term compared with non-exercise (e.g. usual care, education). Yoga had the same effect on pain and disability as any other exercise or physical therapy. Yoga might not improve the physical and mental quality of life based on the result of a merging.

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 Physiological Adaptation to High Altitude with Yoga and Meditation

Improve Physiological Adaptation to High Altitude with Yoga and Meditation

 

By John M. de Castro, Ph.D.

 

“Pranayama techniques allow for maximizing your lung capacity, which becomes critical at high altitudes.” – D.. M. Kumar

 

Breathing is essential for life and generally occurs automatically. It’s easy to take for granted as it’s been there our entire lives. Nevertheless, we become more aware of it when it varies with circumstances, such as when we exercise, in emotional states, especially fear and anxiety, and at high altitude. Breathing exercises are common in yoga practices and have been found to have a number of beneficial effects. High altitude taxes the physiology and particularly the respiratory system. Since yoga practice can improve respiratory function, it would be expected that yoga practice would improve the physiological adaptations needed to function at high altitude.

 

In today’s Research News article “Effect of mindfulness meditation protocol in subjects with various psychometric characteristics at high altitude.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7218243/) Bhanushali and colleagues recruited adults with no prior Kriya Yoga experience and provided them with an intensive 4-day 15 hours per day practice of Kriya Yoga at high altitude (11,500 ft.). The practice consisted of a combination of meditation and yoga. They were measured before and after training for body size, blood pressure, oxygen saturation, cholesterol, triglycerides, psychometric constitution (prakriti), attention, memory, verbal fluency, executive functioning, and information processing speed, anxiety, mental well-being, and happiness.

 

They found that in comparison to baseline, after the Kriya Yoga practice there were significant increases in oxygen saturation, blood glucose, mental well-being and happiness and significant decreases in anxiety, blood triglycerides and very low-density lipoprotein. Hence, after training there were improvements in physical and psychological well-being.

 

These results must be interpreted cautiously as there wasn’t a control comparison condition. So, the results could be due to acclimatization over the 4 days at high altitude and not to the Kriya Yoga practice. Also, without a control condition, participant expectancy effects (placebo), experimenter bias, attentional effects etc. may be responsible for the results. In addition, there was no comparison to other exercises. So, the effects may be due to exercise and not specifically to Kriya Yoga.

 

Taking this into consideration, the results demonstrate that intensive yoga practice can be conducted at high altitude and shows potential for improving physical and psychological acclimatization to high altitude.

 

So, improve physiological adaptation to high altitude with yoga and meditation.

 

“BREATHE — the universal mantra of yoga. This can be a bit harder than normal at thousands feet above sea level. There’s 20 percent less oxygen (or more!) in the air at these elevations. You may experience headache, fatigue, dizziness, nausea, shortness of breath, and sleep disturbance (and sleep is oh-so-important). If you’re feeling like you’re suffering from a bad hangover or the flu, chances are your body is struggling to adapt to the change in altitude.”.- Vicki Kahn

Study Summary

 

Bhanushali, D., Tyagi, R., Limaye Rishi Nityapragya, N., & Anand, A. (2020). Effect of mindfulness meditation protocol in subjects with various psychometric characteristics at high altitude. Brain and behavior, 10(5), e01604. https://doi.org/10.1002/brb3.1604

 

Abstract

Introduction

Incidence of high altitude‐related sickness is increasing due to more number of people visiting the areas of high altitude which may result in life‐threatening conditions including acute mountain sickness (AMS), high altitude pulmonary edema (HAPE), high altitude cerebral edema (HACE), and High‐altitude pulmonary hypertension (HAPH). We hypothesized that an advanced yoga regimen may be beneficial in dealing with the physiology of acclimatization.

Methods

Anthropometric, Biochemical, and Psychological assessments were carried out in 48 participants before and after the advance meditation program (AMP) in the experimental group. Individuals with an age range of 20–65 years with no comorbidities were included in the study. Participants were exposed to AMP for 4 days. All assessments were carried out at the baseline and after the course. Prakriti was constituted for all participants using a standard questionnaire. The study was carried out after obtaining the written informed consent as per the guidelines outlined by the Institute Ethics Committee.

Results

Po2 and glucose levels were found significantly reduced along with changes in the Happiness index, anxiety, and mental well‐being. However, participants with lowered Po2, after 4 days of mindfulness intervention, showed a positive outcome measured by the established scales of anxiety, happiness, and information processing. Psychometric or Prakriti wise analysis revealed that subject with “Pitta” constitution exposed to high altitude and advance meditation showed changes in more parameters than “Vatta” or “Kapha” Constitution.

Conclusions

Advance meditation in the high altitude zone confers biochemical and neuro‐cognitive benefits. Molecular studies may require to understand the role of hypoxic condition in improving the disease state.

Improve the Symptoms of Lymphangioleiomyomatosis, a Rare Lung Disease, with Yoga

Improve the Symptoms of Lymphangioleiomyomatosis, a Rare Lung Disease, with Yoga

 

By John M. de Castro, Ph.D.

 

“The daily practice of yoga can help in strengthening the muscles of the chest, increase lung capacity and boost oxygen intake.” – Ayurvalley

 

Lymphangioleiomyomatosis (LAM) is a very rare lung disease “caused by the abnormal growth of smooth muscle cells, especially in the lungs and lymphatic system. This abnormal growth leads to the formation of holes or cysts in the lung.” (Cleveland Clinic). It is a progressive disease that has symptoms similar to asthma and bronchitis. It is most prevalent in women during the prime of their lives, ages 20 to 40 years. There are no cures for LAM and treatment usually involves drugs that slow the disease progression.

 

Yoga has been shown to improve exercise tolerance and overall health and includes breathing exercises. Indeed, it has been shown that yoga practice improves the mental and physical health of patients with Chronic Obstructive Pulmonary Disease (COPD). So, it may be appropriate for patients with Lymphangioleiomyomatosis (LAM). Hence, there is a need for research into the effectiveness of yoga practice for LAM.

 

In today’s Research News article “Effects of yoga on exercise capacity in patients with lymphangioleiomyomatosis: a nonrandomized controlled study.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7075042/) Li and colleagues adult patients with lymphangioleiomyomatosis (LAM) who have stable disease and assigned them to either no-treatment or to receive Hatha yoga training for 90 minutes once a week for 24 weeks along with twice a week for 15 minutes home practice. They were measured before and after training for walking and afterward dyspnea, VO2peak and anaerobic threshold during an exercise test, lung function, activity, quality of life, anxiety and depression.

 

They found excellent participation and compliance with 92% attendance at the yoga training sessions and a median at how practice of 75 minutes per week. They found that in comparison to baseline and the no-treatment control group that the patients who received yoga training there was a significant large improvement in walking, and cardiopulmonary anerobic threshold, and peak workload.

 

These excellent results have to be tempered by the fact that the yoga and control groups were not randomly assigned. Rather patients within a city were compared to patients outside the city. But, as pilot results, they support a development of a large randomized control trial. The results suggest that yoga practice significantly improves motor function and cardiopulmonary function in patients with lymphangioleiomyomatosis (LAM). This would represent a significant improvement in the patients’ health.

 

So, improve the symptoms of lymphangioleiomyomatosis, a rare lung disease, with yoga.

 

“the beneficial effects of yoga on exercise capacity and pulmonary function were the most robust.” – Brandon May

Abstract

Objective

To evaluate the effects of yoga on exercise capacity and quality of life in patients with lymphangioleiomyomatosis (LAM), a rare cystic lung disease in women.

Patients and methods

This was a nonrandomized, controlled study conducted in Beijing, China (August 27, 2017 – April 26, 2018). Twenty-six participants were allocated to the intervention (yoga) group (n = 13) or control group (n = 13). The yoga intervention involved a 24-week program of yoga class training for 90 min once a week and no fewer than 2 at-home sessions per week (at least 15 min per session). The 6-min walking distance (6MWD), lung function, serum vascular endothelial growth factor-D (VEGF-D) levels, quality of life, and symptoms of anxiety and depression were measured at baseline, 12-week and 24-week follow-up. An incremental cardiopulmonary exercise test was conducted at baseline and the 24-week follow-up.

Results

Eleven patients completed the yoga training program. The yoga group exhibited improvements in the following outcomes versus those of the control group: 6MWD (+ 55 ± 29 m vs + 18 ± 49 m, P = 0.04), anaerobic threshold (3.4 ± 2.4 ml/min/kg vs 1.6 ± 1.4 ml/min/kg, P = 0.035) and peak work load (11.7 ± 14.6 W vs 0.2 ± 9.1 W, P = 0.027). There was no significant difference in peak oxygen consumption (VO2peak), lung function, VEGF-D level, and quality of life between the yoga and control groups. No adverse effects were found in the yoga group.

Conclusion

Yoga is a feasible and safe intervention for pulmonary rehabilitation and potentially improves exercise capacity in patients with LAM.

Yoga Improves Spirituality and Psychological Health Regardless of Instruction

Yoga Improves Spirituality and Psychological Health Regardless of Instruction

 

By John M. de Castro, Ph.D.

 

“While in the Western world most people recognize the more physical practices of yoga – particularly the poses, or asana – it is a practice that’s about much more than just our physical bodies. In Sanskrit language, the word “yoga” literally means “union.” – Katie M.

 

Yoga developed in India millennia ago as a deep spiritual practice. It developed as a contemplative practice that unified body and mind. Yoga was known to have physical benefits, but the most important benefit was seen to be spiritual development. But as yoga emerged and was practiced in the west it was secularized. This was for good reason, as western society was not ready to accept an ancient eastern spiritual practice. As a result, to the vast majority of westerners, yoga is an exercise for physical fitness. It is a means to mold the body to look good, as a health promoting practice, and as a strategy to help lose weight.

 

One important factor for the development of spirituality might be the way that practitioners are instructed. If the yoga instruction is focused on spiritual development then it is possible that the spiritual focus elicited would tend to facilitate spiritual growth. On the other hand, if the instruction is focused on physical development, then spiritual development may be lessened.

Placebo and participant expectancy effects are well known to produce profound effects on the individual. So, instruction may be essential to whether physical or spiritual growth develops from yoga practice. This idea has not been well explored.

 

In today’s Research News article “Verbal Cuing Is Not the Path to Enlightenment. Psychological Effects of a 10-Session Hatha Yoga Practice.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7351526/) Csala and colleagues recruited female yoga naïve undergraduate students and randomly assigned them to receive either 10 weekly 1.5 hour yoga sessions with instructions focusing either on the spiritual aspects of yoga or on the physical benefits of yoga or to a no-treatment control condition. They were measured before and after training for mindfulness, body awareness, positive and negative emotions, and spiritual connections.

 

They found that there were no significant differences between the two yoga groups so they were merged for comparison to the control condition. The yoga groups in comparison to baseline and the control condition had significant increases in spiritual connections and decreases in negative emotions. Hence, practicing yoga by novice college females increased their spirituality and improved their emotional state.

 

 

These results are surprising in that the same increase in spirituality occurred in the yoga groups regardless of whether the spiritual aspects or the physical aspects of yoga were emphasized in the instructions provided. This suggests that yoga has spiritual benefits regardless of the instructions given. Not surprisingly, as observed in previous studies, yoga practice improves the practitioners emotional state. College is a difficult and stressful time and very negative emotions can be elicited interfering with the students’ adjustments to college and performance. The results suggest that yoga practice may be helpful.

 

So, yoga improves spirituality and psychological health regardless of instruction.

 

“many people think of yoga as just physical exercises — the asanas or postures that have gained widespread popularity in recent decades — but these are actually only the most superficial aspects of this profound science of unfolding the infinite potential of the human mind and soul.” – Yogananda

Abstract

Verbal instructions provided during yoga classes can differ substantially. Yoga instructors might choose to focus on the physical aspects of yoga (e.g., by emphasizing the characteristics of the poses), or they might take a more spiritual approach (e.g., by mentioning energy flow and chakras). The present study investigated the effects of verbal cues during yoga practice on various psychological measures. Eighty-four female students (22.0 ± 3.80 years) participated in the study. Two groups attended a beginner level hatha yoga course in which physically identical exercise was accompanied by different verbal cues. The so-called “Sport group” (N = 27) received instructions referring primarily to the physical aspects of yoga practice, while the “Spiritual group” (N = 23) was additionally provided with philosophical and spiritual information. A control group (N = 34) did not receive any intervention. Mindfulness, body awareness, spirituality, and affect were assessed 1 week before and after the training. 2 × 3 mixed (time × intervention) ANOVAs did not show an interaction effect for any of the variables. However, when the two yoga groups were merged and compared to the control group, we found that spirituality increased, and negative affect decreased among yoga participants. In conclusion, yoga practice might influence psychological functioning through its physical components, independent of the style of verbal instructions provided.

Activate the Brain and Synchronize the Cerebral Hemispheres with Kriya Yoga

Activate the Brain and Synchronize the Cerebral Hemispheres with Kriya Yoga

 

By John M. de Castro, Ph.D.

 

“Kriya yoga in Sanskrit means “to move.” The yoga combines all the energy in the body of the mind and to increase the concentration and the awareness in the body. It helps in energizing all the parts of your body. The internal organs inside your body thyroid, spleen, liver, and pancreas, are energized which improve your overall health.” – Larissa Smith

 

Mindfulness training has been shown to improve health and well-being. It has also been found to be effective for a large array of medical and psychiatric conditions, either stand-alone or in combination with more traditional therapies. There are a wide variety of different mindfulness training techniques. Sudarshan Kriya Yoga (SKY) is an ancient technique that involves cyclical breathing patterns that range from slow and calming to rapid and stimulating. How exactly SKY produces its benefits is unknown.

 

One way to observe the effects of mindfulness practices is to measure changes in the electroencephalogram (EEG), the rhythmic electrical activity that can be recorded from the scalp. The recorded activity can be separated into frequency bands. Delta activity consists of oscillations in the 0.5-3 cycles per second band. Theta activity in the EEG consists of oscillations in the 4-8 cycles per second band. Alpha activity consists of oscillations in the 8-12 cycles per second band. Beta activity consists of oscillations in the 13-30 cycles per second band while Gamma activity occurs in the 30-100 cycles per second band.

 

In today’s Research News article “High-Frequency Cerebral Activation and Interhemispheric Synchronization Following Sudarshan Kriya Yoga as Global Brain Rhythms: The State Effects.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7336945/) Bhaskar and colleagues recruited adult Sudarshan Kriya Yoga practitioners. They recorded the electroencephalogram (EEG) for 5 minutes before and after a 1-hour Sudarshan Kriya Yoga practice.

 

They found that after Sudarshan Kriya Yoga (SKY) practice there was a significant increase in the spectral power of all EEG frequency bands. They also found that after SKY there was a significant increase in the synchronization of the electrical activity in the rwo cerebral hemispheres. These results indicate that a single session of SKY increases overall brain activity and interhemispheric synchronization.

 

These findings suggest that Sudarshan Kriya Yoga (SKY) practice heightens neural activity in a synchronized fashion. This suggests that SKY practice improves physiological balance, alertness, and mental well-being. It remains for future research to determine whether these changes in brain activity occur in SKY naive participants and whether these changes are lasting or only occurring in the immediate aftermath of SKY practice.

 

So, activate the brain and synchronize the cerebral hemispheres with Kriya Yoga.

 

“Kriya Yoga is universal in its benefits: it doesn’t depend on anything outside itself.” — Paramhansa Yogananda

Abstract

Context:

Respiration is known to modulate neuronal oscillations in the brain and is measured by electroencephalogram (EEG). Sudarshan Kriya Yoga (SKY) is a popular breathing process and is established for its significant effects on the various aspects of physiology and psychology.

Aims:

This study aimed to observe neuronal oscillations in multifrequency bands and interhemispheric synchronization following SKY.

Settings and Design:

This study employed before- and after-study design.

Subjects and Methods:

Forty healthy volunteers (average age 25.45 ± 5.75, 23 males and 17 females) participated in the study. Nineteen-channel EEG was recorded and analyzed for 5 min each: before and after SKY. Spectral power for delta, theta, alpha, beta, and gamma frequency band was calculated using Multi-taper Fast Fourier Transform (Chronux toolbox). The Asymmetry Index was calculated by subtracting the natural log of powers of left (L) hemisphere from the right® to show interhemispheric synchronization.

Statistical Analysis:

Paired t-test was used for statistical analysis.

Results:

Spectral power increased significantly in all frequency bands bilaterally in frontal, central, parietal, temporal, and occipital regions of the brain after long SKY. Electrical activity shifted from lower to higher frequency range with a significant rise in the gamma and beta powers following SKY. Asymmetry Index values tended toward 0 following SKY.

Conclusions:

A single session of SKY generates global brain rhythm dominantly with high-frequency cerebral activation and initiates appropriate interhemispheric synchronization in brain rhythms as state effects. This suggests that SKY leads to better attention, memory, and emotional and autonomic control along with enhanced cognitive functions, which finally improves physical and mental well-being.

Yoga Changes the Brain to Improve Body Awareness, Attention, and Present Moment Awareness

 

By John M. de Castro, Ph.D.

 

“Similar to the effects of meditation, yoga is a neurological vacation – but it also awakens parts of the brain that are typically inactive during normal day-to-day activity. . . The mind becomes deeply intertwined with the body and the two become one – opening up the flow of communication.” – Morgan Garza

 

The practice of yoga has many benefits for the individual’s physical and psychological health. Yoga has diverse effects because it is itself diverse having components of exercise, mindfulness meditation, and spirituality. So, yoga nourishes the body, mind, and spirit. As a result, yoga practice would be expected to produce physical changes. These include the relaxation response and stress relief. These should be obvious in the muscles, tendons and joints, but, less obvious in the nervous system. The nervous system changes in response to how it is used and how it is stimulated in a process called neuroplasticity. Highly used areas grow in size and connectivity. Mindfulness practices in general are known to produce these kinds of changes in the structure, connectivity, and activity of the brain. Indeed, yoga practice has been shown to protect the brain from age related degeneration.

 

The research on yoga effects on the nervous system is accumulating. It makes sense to pause and look at what has been learned. In today’s Research News article “What Has Neuroimaging Taught Us on the Neurobiology of Yoga? A Review.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7362763/) van Aalst and colleagues review and summarize 34 published research studies of the effects of yoga practice on the brain. The studies mainly included healthy adults.

 

They report that the published research studies used a wide variety of different yoga practices and as a result there were differences in the reported changes to the brain. Regardless, there were a number of similarities in the changes. They report that yoga practice increased the volume of brain areas especially the insular cortex and the hippocampus. Studies of activation of the brain have demonstrated that yoga produces increased activation of prefrontal cortical areas. Finally, studies of connectivity of brain areas have demonstrated that yoga practice increases functional connectivity in a series of brain areas that are known as the default mode network.

 

Yoga is known to increase body awareness. So, it is no surprise that the insular cortex is expanded by yoga practice. It has been shown to be involved in interoceptive body awareness. Yoga is also known to increase attentional ability. So, it is no surprise that the prefrontal cortical areas have increased activation with yoga practice. They have been shown to be involved in attention processing. Yoga is known to increase present moment awareness and decrease mind wandering. So, it is no surprise that yoga produces increased functional connectivity among the structures of the dorsal mode network. They have been shown to be involved in mind wandering and a lack of present moment awareness.

 

So, although differences in yoga practices produce differences in observed changes in the brain, there appear to consistent similarities. Yoga practice changes the brain in areas underlying body awareness, attention, and present moment awareness. It can be speculated that these changes in the brain underlie many of the physical and psychological benefits of yoga practice.

 

So, yoga changes the brain to improve body awareness, attention, and present moment awareness.

Abstract

Yoga is becoming increasingly popular worldwide, with several implicated physical and mental benefits. Here we provide a comprehensive and critical review of the research generated from the existing neuroimaging literature in studies of yoga practitioners. We reviewed 34 international peer-reviewed neuroimaging studies of yoga using magnetic resonance imaging (MRI), positron emission tomography (PET), or single-photon emission computed tomography (SPECT): 11 morphological and 26 functional studies, including three studies that were classified as both morphological and functional. Consistent findings include increased gray matter volume in the insula and hippocampus, increased activation of prefrontal cortical regions, and functional connectivity changes mainly within the default mode network. There is quite some variability in the neuroimaging findings that partially reflects different yoga styles and approaches, as well as sample size limitations. Direct comparator groups such as physical activity are scarcely used so far. Finally, hypotheses on the underlying neurobiology derived from the imaging findings are discussed in the light of the potential beneficial effects of yoga.

Reduce Occupational Stress in School Principals with Yoga

Reduce Occupational Stress in School Principals with Yoga

 

By John M. de Castro, Ph.D.

 

“yoga is a good practice in the workplace as a means of reducing stress,” said Stacy Hunter

 

Stress is epidemic in the western workplace with almost two thirds of workers reporting high levels of stress at work. This often produces burnout; fatigue, cynicism, emotional exhaustion, and professional inefficacy. In a school setting, this exhaustion not only affects teachers and administrators personally, but also the students and schools, as it produces a loss of enthusiasm, empathy, and compassion. School principals are in a particularly stressful position dealing not only with teachers, staff, and students, but also with parents, school boards, and system administrators.

 

Hence, there is a need to identify methods of reducing stress and improving school principal psychological health. Mindfulness has been demonstrated to be helpful in reducing the psychological and physiological responses to stress and for treating and preventing burnout in a number of work environments. Yoga practice has the extra benefits of not only being mindfulness training but also as an exercise. Hence, it’s important to study the effects of yoga practice on the psychological health and burnout symptoms of school principals.

 

In today’s Research News article “Impact of residential yoga training on occupational stress and health promotion in principals.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7161695/) Verma and colleagues recruited veteran school principals with at least 15 years of experience and provided them with 7 days of yoga practice for 1 hour and 45 minutes twice daily along with 3 hours of daily lectures on stress management, yoga for total health, meditation, yoga in school education, and scientific basis of yoga and pranayama. They were measured before and after the week’s training for occupational stress, including role overload, role ambiguity, role conflict, unreasonable group and political pressure, responsibility for persons, under participation, powerlessness, poor peer relations, intrinsic impoverishment, law status, strenuous working condition, and unprofitability.

 

They found that in comparison to baseline, after yoga training there were significant improvements in occupational stress, including role overload, role ambiguity, role conflict, under participation, powerlessness, intrinsic impoverishment, and law status. But the study should be considered as a pilot study as there was no control group. The before-after research design is subject to a large number of alternative confounding interpretations including demand characteristics, participant expectation effects, attention effects, experimenter bias, etc. So, the positive findings of a significant reduction in occupational stress after the training should be seen as suggesting that is reasonable to conduct a randomized controlled trial.

 

So, reduce occupational stress in school principals with yoga.

Abstract

BACKGROUND:

Occupational stress is known as harmful physical and emotional responses that occur when the requirements of the job do not match the resources, needs, or capabilities of an employee, leading to poor mental and physical health.

OBJECTIVE:

The objective of the present study was to assess the effect of 1-week residential yoga training program on occupational stress and its subscales among principals.

METHODS:

Thirty-three principals with ages 40–59 years completed the assessment. They received yoga training at Kaivalyadham Yoga Institute. All the participants were recruited by Kendriya Vidyalaya Sangathan as part of their on-duty yoga training. At the baseline and after 1 week of yoga training participants were assessed for occupational stress. The yoga intervention was given in the morning and evening for 105 min. Apart from yoga training, all the participants were engaged in lectures based on stress management, yoga for total health, meditation, yoga in school education, and scientific basis of yoga, daily for 3 h.

RESULTS:

The principals showed a significant decrease in role overload (P < 0.001), role ambiguity (P < 0.01), role conflict (P < 0.05), under participation (P < 0.001), powerlessness (P < 0.001), intrinsic impoverishment (P < 0.01), law status (P < 0.001), and overall occupational stress (P < 0.001) after 7 days of yoga training intervention. However, there was no significant change in unreasonable group and political pressure (P > 0.05), responsibility for persons (P > 0.05), poor peer relations (P > 0.05), strenuous working conditions (P > 0.05), and unprofitability (P > 0.05) after yoga training intervention.

CONCLUSION:

The present study suggests that 1 week of residential yoga training program can improve occupational stress in principals.

Normalize Heart Rate Processes with Yoga Practice

Normalize Heart Rate Processes with Yoga Practice

 

By John M. de Castro, Ph.D.

 

“Heart Rate Variability is the ability of the heart rate to change from beat to beat., which is based off the activity of the nervous system. HRV is a more accurate measure of a person’s health than examining only the heart rate.” – Zelinda Yañez

 

In our lives we are confronted with a variety of situations and environments. In order to successfully navigate these differing situations, we must be able to adapt and self-regulate. The Autonomic Nervous System (ANS) is designed to adapt physiologically to the varying demands on us. It is composed of 2 divisions; the sympathetic division underlies activation, including increases in heart rate and blood pressure, while the parasympathetic division underlies relaxation, including decreases in heart rate and blood pressure. A measure of the balance between these systems is provided by the variability of the heart rate.

 

Heart Rate Variability (HRV) 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. Mindfulness has been associated with psychological flexibility and a greater ability to adapt appropriately to differing situations. Indeed, mindfulness practice improves Heart Rate Variability (HRV). It makes sense to determine if yoga practice can also improve heart rate variability.

 

In today’s Research News article “Changes in Heart Rate Variability after Yoga are Dependent on Heart Rate Variability at Baseline and during Yoga: A Study Showing Autonomic Normalization Effect in Yoga-Naïve and Experienced Subjects.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7336948/) Shinba and colleagues recruited adults who were either experienced yoga practitioners or yoga naïve. The engaged in 20 minutes of seated breath awareness and yogic breathing exercises. Their electrocardiogram heart rates were recorded before, during, and after the practice.

 

They found that the low frequency component of heart rate variability and the ratio of the low frequency to the high frequency component were normalized after yoga practice such that when the baseline levels were low the components increased as a result of yoga practice and when the baseline levels were high the components decreased. No significant changes in the high frequency component was observed.

 

The results do not replicate previous findings that yoga practice increases the high frequency component of heart rate variability reflecting an increase in parasympathetic activity which is associated with physiological relaxation. This lack of replication may be due to the brevity of the practice or to the nature of the practice where only breath awareness and breathing exercises were included. It is possible that more active components such as postures are needed to produce increases in parasympathetic activity.

 

The low frequency component of heart rate variability reflects the regulation of the heart rate based upon blood pressure. This reflects the maintenance of an adequate blood flow at all times. Hence, the present brief breath-oriented yoga practice appears to regularize blood flows. This, in turn, may reflect an increased ability of the physiology to deal with stresses.

 

So, normalize heart rate processes with yoga practice.

 

“HRV is an interesting and noninvasive way to identify these ANS imbalances. If a person’s system is in more of a fight-or-flight mode, the variation between subsequent heartbeats is low. If one is in a more relaxed state, the variation between beats is high. In other words, the healthier the ANS the faster you are able to switch gears, showing more resilience and flexibility.” – Marcelo Campos

Shinba, T., Inoue, T., Matsui, T., Kimura, K. K., Itokawa, M., & Arai, M. (2020). Changes in Heart Rate Variability after Yoga are Dependent on Heart Rate Variability at Baseline and during Yoga: A Study Showing Autonomic Normalization Effect in Yoga-Naïve and Experienced Subjects. International journal of yoga, 13(2), 160–167. https://doi.org/10.4103/ijoy.IJOY_39_19

 

Abstract

Background:

Yoga therapy is widely applied to the maintenance of health and to treatment of various illnesses. Previous researches indicate the involvement of autonomic control in its effects, although the general agreement has not been reached regarding the acute modulation of autonomic function.

Aim:

The present study aimed at revealing the acute effect of yoga on the autonomic activity using heart rate variability (HRV) measurement.

Methods:

Twenty-seven healthy controls participated in the present study. Fifteen of them (39.5 ± 8.5 years old) were naïve and 12 (45.1 ± 7.0 years old) were experienced in yoga. Yoga skills included breath awareness, two types of asana, and two types of pranayama. HRV was measured at the baseline, during yoga, and at the resting state after yoga.

Results:

In both yoga-naïve and experienced participants, the changes in low-frequency (LF) component of HRV and its ratio to high-frequency (HF) component (LF/HF) after yoga were found to be correlated negatively with the baseline data. The changes in LF after yoga were also correlated with LF during yoga. The changes in HF as well as the raw HRV data after yoga were not related to the baseline HRV or the HRV during yoga.

Conclusion:

The results indicate that yoga leads to an increase in LF when LF is low and leads to a decrease in LF when it is high at the baseline. This normalization of LF is dependent on the autonomic modulation during yoga and may underlie the clinical effectiveness of yoga therapy both in yoga-naïve and experienced subjects.

Yoga Practice Improves Mood and Spirituality Regardless of Physical or Spiritual Instruction

Yoga Practice Improves Mood and Spirituality Regardless of Physical or Spiritual Instruction

 

By John M. de Castro, Ph.D.

 

“The word yoga means to join or unite, and yogis view this unison in different ways – the unison of body, mind and spirit, uniting all the aspects of yourself, or uniting with a higher power or spiritual force.” – DoYou

 

Yoga developed in India millennia ago as a deep spiritual practice. It developed as a contemplative practice that unified body and mind. Yoga was known to have physical benefits, but the most important benefit was seen to be spiritual development. But as yoga emerged and was practiced in the west it was secularized. This was for good reason, as western society was not ready to accept an ancient eastern spiritual practice.

 

There are many forms of yoga and many practitioners who are focused on the spiritual aspects of yoga. But, to the vast majority of westerner’s yoga is an exercise for physical fitness. It is a means to mold the body to look good, as a health promoting practice, and as a strategy to help lose weight. These are good and reasonable goals. But they have replaced the spiritual development originally promoted by yoga. As Jon Kabat-Zinn has remarked, ‘there is the potential for something priceless to be lost.’

 

It may be speculated that the instructions provided with yoga training may produce different effects on the physical and spiritual benefits. In today’s Research News article “Verbal Cuing Is Not the Path to Enlightenment. Psychological Effects of a 10-Session Hatha Yoga Practice.” (See summary below or view the full text of the study at: https://www.frontiersin.org/articles/10.3389/fpsyg.2020.01375/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_1373328_69_Psycho_20200709_arts_A) Csala and colleagues recruited female college students with no previous experience with yoga and randomly assigned them to receive 10 weekly 1.5 hour training sessions in Hatha yoga designated either as “Sport” yoga or “Spiritual” yoga or to a no treatment control condition. The “Sport” yoga and “Spiritual” yoga  only differed in instructions. The “Sport” yoga group was instructed with an emphasis on the physical aspects of yoga (e.g., correct position, muscles involved). The “Spiritual” yoga group was instructed with an emphasis on the spiritual aspects of yoga (e.g. energetic body and blockages, chakras, meditations etc.). They were measured before and after training for body awareness, mindfulness, positive and negative emotions, and spiritual connections.

 

They found that in comparison to baseline and the no-treatment control condition the practice of either “Sport” or “Spiritual” yoga produced significant increases in spiritual connections and significant decreases in negative emotions. Hence, regardless of whether the instructions emphasized the physical or spiritual aspects of yoga practice, the same effects occurred of increased spirituality and mood.

 

Yoga practice has been repeatedly shown in prior research studies to improve mood. So, the observed mood enhancement effects were no surprise. But, the ability of yoga practice to increase spirituality even when the spiritual aspects of yoga were not talked about is surprising. Regardless of instruction Hatha yoga practice produced increased spirituality. This suggests that the western emphasis on the secular aspects of yoga may not interfere with the enhancement of spirituality produced by yoga practice.

 

Perhaps yoga practice makes the individual more aware of the physical limitations of the body and that by itself may put human existence into perspective, amplifying the importance of the non-physical, spiritual, aspects. Yoga practice has for centuries been practiced in the east enhancing spirituality. It is interesting to find that it has the same effects in the west even when there is no instruction on the spiritual side of yoga practice.

 

So, yoga practice improves mood and spirituality regardless of physical or spiritual instruction.

Verbal instructions provided during yoga classes can differ substantially. Yoga instructors might choose to focus on the physical aspects of yoga (e.g., by emphasizing the characteristics of the poses), or they might take a more spiritual approach (e.g., by mentioning energy flow and chakras). The present study investigated the effects of verbal cues during yoga practice on various psychological measures. Eighty-four female students (22.0 ± 3.80 years) participated in the study. Two groups attended a beginner level hatha yoga course in which physically identical exercise was accompanied by different verbal cues. The so-called “Sport group” (N = 27) received instructions referring primarily to the physical aspects of yoga practice, while the “Spiritual group” (N = 23) was additionally provided with philosophical and spiritual information. A control group (N = 34) did not receive any intervention. Mindfulness, body awareness, spirituality, and affect were assessed 1 week before and after the training. 2 × 3 mixed (time × intervention) ANOVAs did not show an interaction effect for any of the variables. However, when the two yoga groups were merged and compared to the control group, we found that spirituality increased, and negative affect decreased among yoga participants. In conclusion, yoga practice might influence psychological functioning through its physical components, independent of the style of verbal instructions provided.
