Breath, the vital force of life, is controlled positively by pranayama to ensure homeostasis and wellbeing in humans. Kapalabhati is the rapid breathing technique of pranayama, which is considered as a cure for various ailments. The possible use of this technique to combat metabolic syndrome (MS) and polycystic ovarian syndrome (PCOS) has been discussed in this article. Various published literature from PubMed, Scopus, and theses were reviewed to reinforce the hypothesis that this technique is the answer to ailments due to modernization. It was worthwhile to note that Kapalabhati does combat various features of MS, but its efficacy against PCOS is yet to be proven. However, since both syndromes arise due to a common factor hyperinsulinemia primarily induced by stress in this modern world, it is hypothesized that Kapalabhati holds good against PCOS too. Hence, in conclusion, it can be said that it would be beneficial to conduct a study on PCOS women to ascertain the efficacy of Kapalabhati in their population.

Heart rate variability (HRV) has been used as a proxy for health and fitness and indicator of autonomic regulation and therefore, appears well placed to assess the changes occurring with mind.-body practices that facilitate autonomic balance. While many studies suggest that yoga influences HRV, such studies have not been systematically reviewed. We aimed to systematically review all published papers that report on yoga practices and HRV. A comprehensive search of multiple databases was conducted and all studies that reported a measure of HRV associated with any yoga practice were included. Studies were categorized by the study design and type of yoga practice. A total of 59 studies were reviewed involving a total of 2358 participants. Most studies were performed in India on relatively small numbers of healthy male yoga practitioners during a single laboratory session. Of the reviewed studies, 15 were randomized controlled trials with 6 having a Jadad score of 3. The reviewed studies suggest that yoga can affect cardiac autonomic regulation with increased HRV and vagal dominance during yoga practices. Regular yoga practitioners were also found to have increased vagal tone at rest compared to non-yoga practitioners. It is premature to draw any firm conclusions about yoga and HRV as most studies were of poor quality, with small sample sizes and insufficient reporting of study design and statistical methods. Rigorous studies with detailed reporting of yoga practices and any corresponding changes in respiration are required to determine the effect of yoga on HRV.

Background: In recent years, yoga programs in childhood have been implemented in schools, to promote the development for children. Aim: To investigate the effects of yoga program in physical education classes on the motor abilities and social behavior parameters of 6–8-year-old children. Methods: The study included 16 children from the 1^st grade of a public elementary school in the South of Brazil. The children participated in a 12-week intervention, twice weekly, with 45 min each session. To assess children's performance, we used the Bruininks-Oseretsky Test of Motor Proficiency - Second Edition, the flexibility test (sit and reach – Eurofit, 1988), the Pictorial Scale of Perceived Competence and Social Acceptance for Young Children and semi-structured interviews with children, parents, and classroom' teacher. Data were analyzed with Wilcoxon test and level of significance was 5%. Results: The yoga program was well accepted by children, children also demonstrated significant and positive changes in overall motor abilities scores (balance, strength, and flexibility). In addition, the interviews reported changing in social behavior and the use of the knowledge learned in the program in contexts outside of school. Conclusion: These findings suggest that the implementation of yoga practice in physical education lessons contributed to children's development.

Introduction: Vaqas and Ryan (2003) advocated yoga and breathing exercises for lymphedema. Narahari et al. (2007) developed an integrative medicine protocol for lower-limb lymphedema using yoga. Studies have hypothesized that yoga plays a similar role as that of central manual lymph drainage of Foldi's technique. This study explains how we have used yoga and breathing as a self-care intervention for breast cancer-related lymphedema (BCRL). Methods: The study outcome was to create a yoga protocol for BCRL. Selection of yoga was based on the actions of muscles on joints, anatomical areas associated with different groups of lymph nodes, stretching of skin, and method of breathing in each yoga. The protocol was piloted in eight BCRL patients, observed its difficulties by interacting with patients. A literature search was conducted in PubMed and Cochrane library to identify the yoga protocols for BCRL. Results: Twenty yoga and 5 breathing exercises were adopted. They have slow, methodical joint movements which helped patients to tolerate pain. Breathing was long and diaphragmatic. Flexion of joints was coordinated with exhalation and extension with inhalation. Alternate yoga was introduced to facilitate patients to perform complex movements. Yoga's joint movements, initial positions, and mode of breathing were compared to two other protocols. The volume reduced from 2.4 to 1.2 L in eight patients after continuous practice of yoga and compression at home for 3 months. There was improvement in the range of movement and intensity of pain. Discussion: Yoga exercises were selected on the basis of their role in chest expansion, maximizing range of movements: flexion of large muscles, maximum stretch of skin, and thus part-by-part lymph drainage from center and periphery. This protocol addressed functional, volume, and movement issues of BCRL and was found to be superior to other BCRL yoga protocols. However, this protocol needs to be tested in centers routinely managing BCRL.

Context: Childhood visual deficiency impairs children's neuro-psychomotor development, considerably affecting physical, mental, social, and emotional health. Yoga's multifaceted approach may help children with visual impairment (VI) to cope with their challenges. Aim: This study aimed to develop a special protocol for teaching yoga to children with VI, and to evaluate their preferred method of learning. Methods: The study was carried out at Ramana Maharishi Academy for the Blind, Bengaluru, South India. Forty-one students volunteered to learn yoga practices, and classes were held weekly 5 days, 1 hr per session for 16 weeks. The study introduced a new method using a sequence of five teaching steps: verbal instructions, tactile modeling, step-by-step teaching, learning in a group, and physical guidance. A questionnaire concerning the preferred steps of learning was then given to each student, and verbal answers were obtained. Results: A total of 33 (out of 41), aged 11.97 ± 1.94, 15 girls and 18 boys responded. Twenty-six (78.79%) chose physical guidance as their most favored learning mode. Conclusions: Specially designed protocol may pave the way to impart yoga in an exciting and comfortable way to children with VI. More studies are needed to further investigate the effectiveness of this new yoga protocol in similar settings.

Background: The practice of yoga has a long history as an integrated lifestyle science. Those who have practiced yoga in its full form (including all eight traditional aspects) find that it touches almost every aspect of their inter- and intra-personal lives. Despite this rich history, the West has adopted limited aspects of yoga practice. When understood narrowly as a physical fitness practice, healthful benefits of yoga may be lost, possibly promoting body-consciousness and injury instead. Aim: To understand whether students in healthcare programs view yoga from a physical fitness versus holistic perspective, we explored perceptions of what constitute yoga's essential practices. Methods: We assessed endorsement of the eight limbs of yoga via the acceptability of yoga survey. The sample (n = 498) was recruited from programs in 10 healthcare professions at a Northwestern university. Participants were categorized as nonyogis, contemplators, yogis, and superyogis. Results: Across all groups, findings confirmed a narrow definition of yoga as portrayed in popular media and gym-based yoga classes. Breathing and posture practices were the most commonly endorsed practices, even among the sample's most seasoned yoga practitioners. Ethical practices and daily commitments of introspection, disciplined practice, or living with purity were least commonly associated with yoga despite their foundational nature in yoga philosophy. Concentration and meditation practices were only moderately endorsed as essential practices. Super-yogis endorsed a wider variety of limbs than nonyogis, contemplators, and yogis. Conclusions: We offer a rationale for these findings along with recommendations that may help augment the definition of yoga and hence maximize its benefits.

Context: Psychological comorbidities are prevalent in coal miners with chronic obstructive pulmonary disease (COPD) and contribute to the severity of the disease reducing their health status. Yoga has been shown to alleviate depression and anxiety associated with other chronic diseases but in COPD not been fully investigated. Aim: This study aimed to evaluate the role of yoga on health status, depression, and anxiety in coal miners with COPD. Materials and Methods: This was a randomized trial with two study arms (yoga and control), which enrolled 81 coal miners, ranging from 36 to 60 years with stage II and III stable COPD. Both groups were either on conventional treatment or combination of conventional care with yoga program for 12 weeks. Results: Data were collected through standardized questionnaires; COPD Assessment Test, Beck Depression Inventory and State and Trait Anxiety Inventory at the beginning and the end of the intervention. The yoga group showed statistically significant (P < 0.001) improvements on all scales within the group, all significantly different (P < 0.001) from changes observed in the controls. No significant prepost changes were observed in the control group (P > 0.05). Conclusion: Yoga program led to greater improvement in physical and mental health status than did conventional care. Yoga seems to be a safe, feasible, and effective treatment for patients with COPD. There is a need to conduct more comprehensive, high-quality, evidence-based studies to shed light on the current understanding of the efficacy of yoga in these chronic conditions and identify unanswered questions.

Context: An individualized approach of providing yoga support can address many of the disease-related concerns indicated in the management of diabetes, specifically the impact on other life activities and long-term functional wellbeing. Aim: To analyze the role of regular yoga practice as a self-management approach to achieve glycemic control and psychological wellbeing in Type II diabetic patients. Methods: Ninety-one subjects of both sexes responded to the announcement and consented to participate in the study. This was a single group, before and after yoga evaluation without control comparison. The fasting and postprandial blood sugar, glycosylated hemoglobin (HBA1c), cognitive tasks, depression, cognitive failure, and diabetic-related quality of life (QOL) were measured as pretest. The subjects underwent one-to-one individualized yoga therapy sessions, which included 12 supervised sessions spread over a 3-month period. The posttest data were analyzed using paired t-test and Wilcoxon paired rank test. Results: Showed significant reduction in fasting blood sugar. QOL of the diabetic patients had improved significantly. There was a significant reduction in the frequency (mean difference of 7.58,P > 0.01) of depressive symptoms and intensity of depression (mean difference 1.66,P > 0.05). Concentration and attention span improved significantly and mean discrepancy score reduced (mean difference 3.42,P > 0.01). There were no marked changes in the postprandial blood sugar and HBA1c. Conclusion: Yoga practice enhances the subjective wellbeing, QOL, improves mood and concentration, and facilitates achievement of adequate glycemic control among Type II diabetic patients.

Depression is the most common mental illness in the elderly, and cost-effective treatments are required. Therefore, this study is aimed at evaluating the effectiveness of a mindfulness-based cognitive therapy (MBCT) on depressive symptoms, mindfulness skills, acceptance, and quality of life across four domains in patients with late-onset depression. A single case design with pre- and post-assessment was adopted. Five patients meeting the specified inclusion and exclusion criteria were recruited for the study and assessed on the behavioral analysis pro forma, geriatric depression scale, Hamilton depression rating scale, Kentucky inventory of mindfulness skills, Acceptance and Action Questionnaire II, The World Health Organization quality of life Assessment Brief version (WHOQO-L-BREF). The therapeutic program consisted of education regarding the nature of depression, training in formal and informal mindfulness meditation, and cognitive restructuring. A total of 8 sessions over 8 weeks were conducted for each patient. The results of this study indicate clinically significant improvement in the severity of depression, mindfulness skills, acceptance, and overall quality of life in all 5 patients. Eight-week MBCT program has led to reduction in depression and increased mindfulness skills, acceptance, and overall quality of life in patients with late-life depression.

Sirsasana is a type of headstand postural yoga in which the body is completely inverted. It is performed with or without wall support. In this position, the body is held upright supported by the forearms, while the crown of the head rests lightly on the floor. This is an advanced pose and should be attempted under the supervision of a qualified yoga instructor. The practice of Sirsasana is postulated to increase blood flow to the brain, improving memory, and other intellectual functions. It is also known to cause causes raised intraocular pressure, decompression retinopathy, glaucomatous visual field defects, central retinal vein occlusion, progression of glaucoma, optic neuropathy, and conjunctival varix thrombosis. We report a case of branch retinal vein occlusion following Sirsasana in a patient with systemic hypertension.
