Biological markers for the effects of yoga as a complementary and alternative medicine

Remodeling the Epigenome Through Meditation: Effects on Brain, Body, and Well-being

Epigenetic mechanisms are key processes that constantly reshape genome activity carrying out physiological responses to environmental stimuli. Such mechanisms regulate gene activity without modifying the DNA sequence, providing real-time adaptation to changing environmental conditions. Both favorable and unfavorable lifestyles have been shown to influence body and brain by means of epigenetics, leaving marks on the genome that can either be rapidly reversed or persist in time and even be transmitted trans-generationally. Among virtuous habits, meditation seemingly represents a valuable way of activating inner resources to cope with adverse experiences. While unhealthy habits, stress, and traumatic early-life events may favor the onset of diseases linked to inflammation, neuroinflammation, and neuroendocrine dysregulation, the practice of mindfulness-based techniques was associated with the alleviation of many of the above symptoms, underlying the importance of lifestyles for health and well-being. Meditation influences brain and body systemwide, eliciting structural/morphological changes as well as modulating the levels of circulating factors and the expression of genes linked to the HPA axis and the immune and neuroimmune systems. The current chapter intends to give an overview of pioneering research showing how meditation can promote health through epigenetics, by reshaping the profiles of the three main epigenetic markers, namely DNA methylation, histone modifications, and non-coding RNAs.

The psychosomatic impact of Yoga in medical education: a systematic review and meta-analysis

Non-clinical approaches such as meditation, yoga, and mindfulness are popular traditional therapeutical interventions adopted by many educational institutions to improve the physical and mental well-being of learners. This study aimed to evaluate the effectiveness of yoga intervention in improving cardiopulmonary parameters such as blood pressure, heart rate, pulmonary function tests and psychosomatic symptoms such as depression, anxiety and stress in medical and dental students. Using the PRISMA protocol, a search from databases such as PubMed, Scopus, and Embase resulted in 304 relevant articles. After screening the title and abstracts, 47 papers were analyzed thoroughly and included in the qualitative analysis. 18 articles with homogenous statistical data on physiology and psychological parameters were included for meta-analysis. In comparison to the control group, the study showed a significant reduction of systolic blood pressure (SBP: 6.82 mmHg, z = -3.06, p = 0.002), diastolic blood pressure (DBP: 2.92 mmHg, z = -2.22, p = 0.03), and heart rate (HR: 2.55 beats/min, z = -2.77, p = 0.006). Additionally, data from 4 studies yielded a significant overall effect of a stress reduction of 0.77 on standardized assessments due to the yoga intervention (z = 5.29, p < 0.0001). Lastly, the results also showed a significant (z = -2.52, p = 0.01) reduction of 1.2 in standardized anxiety tests in intervention group compared to the control. The findings offer promising prospects for medical educators globally, encouraging them to consider reformation and policymaking in medical curricula to enhance academic success and improve the overall quality of life for medical students worldwide.

[Complementary and integrative medicine in cancer-related fatigue]

The majority of cancer patients experience fatigue during the course of their illness. Fatigue should not be seen as an inevitable consequence of cancer and its treatment. Cancer-related fatigue (CRF) is a multidimensional symptom complex that is influenced by a variety of factors. Complementary medicine approaches offer potentially promising strategies to address this fatigue and can therefore be a valuable addition to conventional therapies.In this narrative review, complementary medicine treatment approaches for tumor-associated fatigue are presented according to the historical development and current scientific evidence. The focus is on methods with the highest current evidence based on the recommendations of national and international guidelines. Therapeutic approaches from mind-body medicine, such as mindfulness-based stress reduction (MBSR), mindfulness-based cognitive therapy (MBCT), yoga, tai chi, and qigong, as well as acupuncture, acupressure, moxibustion, and phytotherapeutic treatment approaches are presented.In Germany, the complementary therapies listed here are not generally covered by health insurances. However, a few clinics have developed comprehensive programs in mind-body medicine, for which cost coverage has already been obtained. As a result, complementary medical treatments for cancer-related fatigue that adhere to national and international guidelines are typically available only as private services or within the framework of study participation.

The Effect of Breathing and Relaxation Exercises on Self-Care, Dyspnea, and Fatigue in Heart Failure: A Randomized Controlled Study

Dyspnea, fatigue, and self-care are common occurrences of heart failure. This study evaluated the effects of yoga breathing and progressive muscle relaxation exercises on dyspnea, fatigue, and self-care in heart failure. The study conducted between April 2023 and March 2024 randomized 66 heart failure patients into 3 groups (yoga breathing exercise, progressive muscle relaxation exercise, and control). The intervention groups engaged in specific exercises tailored to their assigned regimen for 10 minutes twice daily over a 2-week period, while the control group maintained their pharmacological treatment. At the end of the intervention (second week) yoga breathing exercise notably ameliorated fatigue, dyspnea, and self-care (P < .001), changes in saturation, heart rate, and respiratory rate favoring the intervention groups (P < .05). Yoga breathing exercises enhance self-care, alleviate fatigue, and dyspnea in heart failure. Additionally, yoga breathing and progressive muscle relaxation exercises provide benefits in regulating saturation, heart rate, and respiratory rate in heart failure.

High-intensity interval training vs. yoga in improving binge eating and physical fitness in inactive young females

Yoga is effective in binge eating disorder (BED) treatment, but it does not seem effective enough to improve low physical fitness. In contrast, high-intensity interval training (HIIT) is effective in improving physical fitness but has never been studied in the context of BED. In the study, 47 young inactive females with mild to moderate BED were recruited and randomly assigned to a HIIT group (HIIT), a Yoga group (YG), or a control group (CG; age, 19.47 ± 0.74, 19.69 ± 0.874, and 19.44 ± 0.63 years; BMI, 21.07 ± 1.66, 21.95 ± 2.67, and 20.68 ± 2.61 kg/m2, respectively). The intervention groups participated in 8-week specific exercises, while the CG maintained their usual daily activity. Before and after the training, participants were evaluated for BED using the binge eating scale (BES) and for physical fitness. The obtained data were compared within groups and between groups, and a correlation analysis between BES and physical fitness parameters was performed. After the training, the YG presented significant improvements in BES (- 20.25%, p = 0.006, ηp2 = 0.408), fat mass (FM, - 3.13%, p = 0.033, ηp2 = 0.269), and maximal oxygen consumption (VO2max, 11.51%, p = 0.000, ηp2 = 0.601), whereas the HIIT showed significant improvements in body weight (BW, - 1.78%, p = 0.006, ηp2 = 0.433), FM (- 3.94%, p = 0.033, ηp2 = 0.285), and BMI (- 1.80%, p = 0.006, ηp2 = 0.428), but not in BES. Comparisons between groups revealed that both HIIT and YG had significantly higher VO2max levels than CG (HIIT 12.82%, p = 0.006, ηp2 = 0.088; YG: 11.90%, p = 0.009, ηp2 = 0.088) with no difference between HIIT and YG. Additionally, YG presented significantly lower BES than both HIIT (15.45%, p = 0.02, ηp2 = 0.03) and CG (11.91%, p = 0.022, ηp2 = 0.03). In conclusion, Yoga is an effective treatment for BED, but HIIT is not, despite its high efficacy in improving physical fitness.

Are There Biological Correlates of Response to Yoga-Based Interventions in Depression? A Critical Scoping Review

Depression is the most common mental disorder worldwide. Both antidepressants and psychotherapy are effective in treating depression, but the response to these treatments is often incomplete. Yoga-based interventions (YBIs) have been advocated by some researchers as a promising form of alternative treatment for depression. Recent research has attempted to identify the biological mechanisms associated with the antidepressant actions of YBIs. In this scoping review, conducted according to the PRISMA-ScR guidelines, the PubMed and Scopus databases were searched to retrieve research on biomarkers of response to YBIs in patients with depression. These studies were also critically reviewed to evaluate their methodological quality and any sources of bias. Nineteen studies were included in the review. Based on these studies, there is preliminary evidence that YBIs may be associated with increased serum brain-derived neurotrophic factor (BDNF) and reduced serum cortisol and interleukin-6 (IL-6) in patients with depression. However, many of these changes were also observed in the control arms, and the overall quality of the research was low. At present, it cannot be concluded that there are reliable biomarkers of response to YBIs in depression, though there are some potential biological correlates. Further advances in this field will depend critically on improvements in study design, particularly the minimization of sources of bias and the selection of more specific and sensitive biomarkers based on existing evidence from other treatment modalities.

Sports and Weight Control in Children

Pediatric obesity is a global concern with distressing comorbid conditions, including mood disturbance, cardiovascular changes, endocrine imbalance, liver disease, sleep apnea, and orthopedic conditions. The primary treatment of this condition includes physical activity. Participating in organized sports has been shown to reduce weight and the complications of pediatric obesity more effectively than individual exercise.

The Therapeutic Potential of Yoga for Alzheimer's Disease: A Critical Review

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive decline, memory impairment, and behavioral changes, significantly impacting the quality of life of affected individuals and their caregivers. While pharmacological treatments offer limited relief, nonpharmacological interventions, like yoga, have gained attention for their potential therapeutic benefits. This critical review synthesizes findings from various studies on the feasibility, adherence, physical function, cognitive improvements, inflammatory markers, neuroprotection, and mood and behavioral changes associated with yoga interventions for older adults with AD. Despite these promising results, further research with randomized controlled trials, larger sample sizes, control groups, longitudinal follow-ups, standardized protocols, and diverse populations is necessary to confirm these benefits and understand the long-term effects of yoga on AD progression. This critical review highlights yoga's potential as a valuable nonpharmacological intervention in the holistic management of AD.

Effectiveness of antenatal yoga in reducing intensity of labour pain: A systematic review and meta-analysis

Background

Yoga during pregnancy was found to be beneficial in various aspects of pregnancy including pain management during the time of labour. The current systematic review and meta-analysis aims to assess the effectiveness of antenatal yoga practices in reducing pain during the time of labour.

Methods

We searched electronic databases such as PubMed, Embase, Cochrane Library, and Web of Science, till January 2023. Randomized controlled trials (RCTs) which measured the effects of antenatal yoga practices on pain management during labour were included. The main outcome was the pain intensity measured with any validated questionnaire. The methodological quality of included studies was evaluated by using a risk-of-bias assessment tool developed by the Cochrane Collaboration. For the effect size, standardized mean differences (SMDs) with a 95% confidence interval (CI) were generated with a random effect model using R software (version 4.2.2).

Results

Eight studies including 576 antenatal women between the age of 14 and 40 years were included. Results of this meta-analysis showed that yoga is effective in reducing labour pain (SMD: -1.34 95% of CI: -1.86, -0.81) with significant heterogeneity among the studies (I2 73%, p < 0.0008).

Conclusion

Antenatal yoga can be a promising intervention in the field of obstetrics to reduce the intensity of labour pain. However, we are still in need of RCT with a large sample size to confirm the reliability of the present meta-analysis.

Exploring Yoga Behaviors among College Students Based on the Multi-Theory Model (MTM) of Health Behavior Change

During college years, perceived stress is the top reported hindrance to well-being and academic success. Data on the acceptance and perceived benefits of yoga among college students are limited. A purposive sample of college students (n = 79) from a course centered on Vinyasa Yoga and Mindfulness Meditation were recruited. Comprehensive yoga journaling data were collected, and a directed content analysis along the constructs of the multi-theory model (MTM) of health behavior change was utilized. The advantages of yoga that emerged were improved physical performance, reduced perceived stress, acceptance of oneself, better well-being, and improved coping. The identified disadvantages were time commitment, lack of motivation, and other competing interests. Learning through small steps, modifications, and identifying multiple sources of confidence helped build behavioral confidence. Practicing at home or at a yoga studio was a common theme for support in the physical environment. Directing negative emotions into purposes was helpful in maintaining the yoga practice. Sustained commitment to the practice also helped maintain the regular performance of yoga. Finally, social support from family, friends, and instructors was vital for continued practice. The study has important ramifications for the development of survey tools for descriptive studies and designing behavior-change yoga interventions in this target population.

Effects of exercise of different intensities on withdrawal symptoms among people with substance use disorder: a systematic review and meta-analysis

Background: Exercise can effectively attenuate withdrawal symptoms and reduce relapse, but it is unknown whether exercise of different intensities produces different results. This study aimed to systematically review the effects of different exercise intensities on withdrawal symptoms among people with substance use disorder (SUD). Methods: Systematic searches for randomized controlled trials (RCTs) on exercise, SUD, and abstinence symptoms were conducted via electronic databases, including PubMed, up to June 2022. Study quality was evaluated using the Cochrane Risk of Bias tool (RoB 2.0) for assessment of risk of bias in randomized trials. The meta-analysis was performed by calculating the standard mean difference (SMD) in outcomes of interventions involving light-, moderate-, and high-intensity exercise for each individual study using Review Manager version 5.3 (RevMan 5.3). Results: In total, 22 RCTs (n = 1,537) were included. Overall, exercise interventions had significant effects on withdrawal symptoms, but the effect size varied with exercise intensity and by outcome measure (i.e., for different negative emotions). Light-, moderate-, and high-intensity exercise reduced cravings after the intervention [SMD = -0.71, 95% CI = (-0.90, -0.52)], and there were no statistical differences between the subgroups (p > 0.05). Light-, moderate-, and high-intensity exercise reduced depression after the intervention [light, SMD = -0.33, 95% CI = (-0.57, -0.09); moderate, SMD = -0.64, 95% CI = (-0.85, -0.42); high, SMD = -0.25, 95% CI = (-0.44, -0.05)], with moderate-intensity exercise producing the best effect (p < 0.05). Only light- and moderate-intensity exercise relieved anxiety after the intervention [light, SMD = -0.48, 95% CI = (-0.71, -0.26); moderate, SMD = -0.58, 95% CI = (-0.85, -0.31)]. Only high-intensity exercise worked in alleviating stress [SMD = -1.13, 95% CI = (-2.22, -0.04)]. Both irritability and restlessness could be improved by light- and moderate-intensity exercise [irritability, SMD = -0.74, 95% CI = (-0.98, -0.50); restless, SMD = -0.72, 95% CI = (-0.98, -0.47)], and there were no statistical differences between the subgroups (p > 0.05). Moderate- and high-intensity exercise decreased withdrawal syndrome after the intervention [moderate, SMD = -0.30, 95% CI = (-0.55, -0.05); high, SMD = -1.33, 95% CI = (-1.90, -0.76)], with high-intensity exercise producing the best effects (p < 0.01). Conclusion: Overall, exercise leads to improvements in withdrawal symptoms in individuals with SUD, but these effects vary significantly between the exercise of different intensities and according to the type of withdrawal symptoms. Moderate-intensity exercise has the greatest benefits in improving depression and anxiety; high-intensity exercise has the greatest benefits in improving withdrawal syndrome.

Restorative yoga therapy for third-year medical students in pediatrics rotation: Working to improve medical student well-being

BACKGROUND

Stress experienced by medical students is a well-documented and widespread phenomenon that may have physical and psychological effects on their well-being. One solution is to provide students with the tools to recognize and cope with stress. The aim of this study was to incorporate restorative yoga training-a well-recognized tool for stress reduction-in the third-year medical student pediatrics clerkship and assess the intervention's impact on students' well-being.

MATERIALS AND METHOD

Restorative yoga, as a prospective intervention, was offered to third-year medical students at Texas Tech University Health Sciences Center during their pediatrics rotation. The study was between March and August 2020. Each yoga session lasted 45-minutes, once a week for six weeks. Participants completed anonymous questionnaires before and after the intervention via the Warwick-Edinburgh Mental Well-being Scale (WEMWBS).

RESULT

Over the six-month study period, 25 (71%) of 35 medical students, having been given the option, chose to participate. The WEMWBS contains 14 statements on well-being, and all but one from the list showed a positive increase in average rating from pre intervention to post intervention. The statements "I've been feeling more relaxed" and "I've been thinking clearly" showed the greatest average increase. Following Chi-squared testing, two statements were found to be significantly different (P < 0.05) before intervention and after intervention: "I've been feeling more relaxed" and "I've been feeling good about myself."

CONCLUSION

Students' well-being is paramount to medical schools. Restorative yoga offers hopeful outcomes for effective mitigation of the stresses of medical education and may be recommended for wider use.

On the road to resilience: Epigenetic effects of meditation

Many environmental and lifestyle related factors may influence the physiology of the brain and body by acting on fundamental molecular pathways, such as the hypothalamus-pituitary-adrenal axis (HPA) and the immune system. For example, stressful conditions created by adverse early-life events, unhealthy habits and low socio-economic status may favor the onset of diseases linked to neuroendocrine dysregulation, inflammation and neuroinflammation. Beside pharmacological treatments used in clinical settings, much attention has been given to complementary treatments such as mind-body techniques involving meditation that rely on the activation of inner resources to regain health. At the molecular level, the effects of both stress and meditation are elicited epigenetically through a set of mechanisms that regulate gene expression as well as the circulating neuroendocrine and immune effectors. Epigenetic mechanisms constantly reshape genome activities in response to external stimuli, representing a molecular interface between organism and environment. In the present work, we aimed to review the current knowledge on the correlation between epigenetics, gene expression, stress and its possible antidote, meditation. After introducing the relationship between brain, physiology, and epigenetics, we will proceed to describe three basic epigenetic mechanisms: chromatin covalent modifications, DNA methylation and non-coding RNAs. Subsequently, we will give an overview of the physiological and molecular aspects related to stress. Finally, we will address the epigenetic effects of meditation on gene expression. The results of the studies reported in this review demonstrate that mindful practices modulate the epigenetic landscape, leading to increased resilience. Therefore, these practices can be considered valuable tools that complement pharmacological treatments when coping with pathologies related to stress.

Preksha Dhyāna Meditation Effect on the DNA Methylation Signature in College Students

Introduction: The stress and psychological factors affect the human transcriptomic and epigenomic landscapes. Preksha Dhyana meditation (PM) was found to be effective, in novice healthy college student meditators, at the cognitive skills and transcriptomic levels. Recently published data showed that PM induced alterations at the transcriptome level in healthy and novice college students. Methods: To decipher potential mechanisms underlying the PM effect at the cellular level, array-based methylation analyses in peripheral blood were performed at baseline and 8 weeks postintervention in 34 participants. Results: Overall, 470 CpG sites were nominally differentially methylated (p ≤ 0.05 and change magnitude from ≥3% to ≤ -3%) between baseline and 8 weeks postintervention with 180 sites hypermethylated and 290 sites hypomethylated. Pathway analysis of the genes linked to the differentially methylated sites revealed the enrichment of several molecular and cellular signaling pathways, especially metabolic and brain function signaling pathways. Conclusions: Besides its beneficial effects on cognitive skills and transcriptome alterations, the current data indicate that PM meditation also affects the DNA methylation profile of novice and healthy college students 8 weeks postintervention. Clinical Trial Registration number: NCT03779269.

A randomized controlled trial of the influence of yoga for women with symptoms of post-traumatic stress disorder

Background

Survivors in motor vehicle accident (MVA) may have posttraumatic stress disorder (PTSD). Yoga is a complementary approach for PTSD therapy.

Methods

This randomized controlled trial explored whether yoga intervention has effects on reducing the symptoms of PTSD in women survived in MVA. Participants (n = 94) were recruited and randomized into control group or yoga group. Participants attended 6 45-minuite yoga sessions in 12 weeks. Depression Anxiety Stress Scales (DASS) and Impact of Events Scale-Revised (IES-R) were used to assess psychological distress.

Results

Post-intervention IES-R total score of yoga group was significantly lower than that of control group (p = 0.01). At both post-intervention and 3-months post intervention, the DASS-21 total scores of yoga group were both significantly lower than those of control group (p = 0.043, p = 0.024). Yoga group showed lower anxiety and depression level compared to control group at both post-intervention (p = 0.033, p < 0.001) and post-follow-up (p = 0.004, p = 0.035). Yoga group had lower levels of intrusion and avoidance compared to control group after intervention (p = 0.002, p < 0.001).

Conclusion

Results illustrate that yoga intervention may alleviate anxiety and depression and improve the symptoms of PTSD in women with PTSD following MVA.

From Precision Metapharmacology to Patient Empowerment: Delivery of Self-Care Practices for Epilepsy, Pain, Depression and Cancer Using Digital Health Technologies

To improve long-term outcomes of therapies for chronic diseases, health promotion and lifestyle modifications are the most promising and sustainable strategies. In addition, advances in digital technologies provide new opportunities to address limitations of drug-based treatments, such as medication non-adherence, adverse effects, toxicity, drug resistance, drug shortages, affordability, and accessibility. Pharmaceutical drugs and biologics can be combined with digital health technologies, including mobile medical apps (digital therapeutics), which offer additional clinical benefits and cost-effectiveness. Promises of drug+digital combination therapies are recognized by pharmaceutical and digital health companies, opening opportunities for integrating pharmacotherapies with non-pharmacological interventions (metapharmacology). Herein we present unique features of digital health technologies which can deliver personalized self-care modalities such as breathing exercises, mindfulness meditation, yoga, physical activity, adequate sleep, listening to preferred music, forgiveness and gratitude. Clinical studies reveal how aforementioned complimentary practices may support treatments of epilepsy, chronic pain, depression, cancer, and other chronic diseases. This article also describes how digital therapies delivering “medicinal” self-care and other non-pharmacological interventions can also be personalized by accounting for: 1) genetic risks for comorbidities, 2) adverse childhood experiences, 3) increased risks for viral infections such as seasonal influenza, or COVID-19, and 4) just-in-time stressful and traumatic circumstances. Development and implementation of personalized pharmacological-behavioral combination therapies (precision metapharmacology) require aligning priorities of key stakeholders including patients, research communities, healthcare industry, regulatory and funding agencies. In conclusion, digital technologies enable integration of pharmacotherapies with self-care, lifestyle interventions and patient empowerment, while concurrently advancing patient-centered care, integrative medicine and digital health ecosystems.

Molecules of Silence: Effects of Meditation on Gene Expression and Epigenetics

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.

Inner Engineering Practices and Advanced 4-day Isha Yoga Retreat Are Associated with Cannabimimetic Effects with Increased Endocannabinoids and Short-Term and Sustained Improvement in Mental Health: A Prospective Observational Study of Meditators

Background

Anxiety and depression are common in the modern world, and there is growing demand for alternative therapies such as meditation. Meditation can decrease perceived stress and increase general well-being, although the physiological mechanism is not well-characterized. Endocannabinoids (eCBs), lipid mediators associated with enhanced mood and reduced anxiety/depression, have not been previously studied as biomarkers of meditation effects. Our aim was to assess biomarkers (eCBs and brain-derived neurotrophic factor [BDNF]) and psychological parameters after a meditation retreat.

Methods

This was an observational pilot study of adults before and after the 4-day Isha Yoga Bhava Spandana Program retreat. Participants completed online surveys (before and after retreat, and 1 month later) to assess anxiety, depression, focus, well-being, and happiness through validated psychological scales. Voluntary blood sampling for biomarker studies was done before and within a day after the retreat. The biomarkers anandamide, 2-arachidonoylglycerol (2-AG), 1-arachidonoylglycerol (1-AG), docosatetraenoylethanolamide (DEA), oleoylethanolamide (OLA), and BDNF were evaluated. Primary outcomes were changes in psychological scales, as well as changes in eCBs and BDNF.

Results

Depression and anxiety scores decreased while focus, happiness, and positive well-being scores increased immediately after retreat from their baseline values (P < 0.001). All improvements were sustained 1 month after BSP. All major eCBs including anandamide, 2-AG, 1-AG, DEA, and BDNF increased after meditation by > 70% (P < 0.001). Increases of ≥20% in anandamide, 2-AG, 1-AG, and total AG levels after meditation from the baseline had weak correlations with changes in happiness and well-being.

Conclusions

A short meditation experience improved focus, happiness, and positive well-being and reduced depression and anxiety in participants for at least 1 month. Participants had increased blood eCBs and BDNF, suggesting a role for these biomarkers in the underlying mechanism of meditation. Meditation is a simple, organic, and effective way to improve well-being and reduce depression and anxiety.

Yoga as an intervention to manage multiple sclerosis symptoms

Multiple sclerosis (MS) is an autoimmune, demyelinating, inflammatory disease of central nervous system (CNS) which is characterized by spasticity, fatigue, depression, anxiety, bowel and bladder dysfunction, impaired mobility, cognitive impairment etc. and affects approximately 2.5 million people worldwide. Disease modifying therapies for MS which help in preventing accumulation of lesions in white matter of CNS are costly and have significant adverse effects. Therefore, patients with MS are using complementary and alternative medicine (CAM) and Yoga is one of the most popular form of CAM which is being used immensely to reduce or overcome the symptoms of MS. In the current review attempted to present the potential impact of yoga practices on reducing MS related symptoms.
