Background: Traditional yoga texts describe "cross nostril breathing," with inhalation and exhalation through different nostrils. Previous research reported no clear differences in oxygen consumption during uninostril breathing (i.e., inhalation and exhalation through the same nostril), hence not supporting right and left uninostril breathing as activating or relaxing, respectively, with no research on oxygen consumed in "cross nostril breathing."

Methods: Oxygen consumed during "cross nostril breathing" was measured in healthy participants (n = 47, males, 26.3 ± 6.4 years). Five sessions (viz., right nostril inspiration yoga breathing [RNIYB], left nostril inspiration yoga breathing [LNIYB], alternate nostril yoga breathing [ANYB], breath awareness (BAW), and quiet rest (QR) were conducted on separate days in random order. Sessions were 33 min in duration with pre, during, and post states.

Results: Volume of oxygen consumed (VO₂) and carbon dioxide eliminated (VCO₂) increased during RNIYB (9.60% in VO₂ and 23.52% in VCO₂), LNIYB (9.42% in VO₂ and 21.20% in VCO₂) and ANYB (10.25% in VO₂ and 22.72% in VCO₂) with no significant change in BAW and QR. Diastolic blood pressure decreased during BAW and QR and after all five sessions (P < 0.05; in all cases). All comparisons were with the respective preceding state.

Conclusion: During the three yoga breathing practices, the volume of oxygen consumed increased irrespective of the nostril breathed through, possibly associated with (i) conscious regulation of the breath; (ii) attention directed to the breath, and (iii) "respiration-locked cortical activation." Restriction of the study to males reduces the generalizability of the findings.

Infertility, a widespread medical condition affecting numerous couples globally, persists as a challenge despite advances in assisted reproductive technologies (ARTs), often burdened by financial, physical, and emotional strains. Complementary and alternative approaches, notably yoga, have garnered attention for potentially enhancing fertility outcomes. Studies reveal yoga's influence on factors contributing to infertility, including reduced oxidative stress (OS) and oxidative DNA damage (ODD). OS, linked to mutagenic base formation, higher malondialdehyde levels, abnormal methylation, and altered gene expression, can impair sperm genome integrity. Yoga's efficacy is evident in lowering OS, positively affecting signal transmission, gene expression, and physiological systems. Furthermore, yoga has a positive impact on addressing the dysregulation of apoptosis, resulting in improved processes such as spermatogenesis, sperm maturation, and motility, while also reducing DNA fragmentation. OS correlates with genome-wide hypomethylation, telomere shortening, and mitochondrial dysfunction, contributing to genome instability. Yoga and meditation significantly reduce OS and ODD, ensuring proper reactive oxygen levels and preserving physiological systems. The review explores potential mechanisms underlying yoga's positive impact on infertility, including enhanced blood flow, reduced inflammation, relaxation response, and modulation of the hypothalamic-pituitary-adrenal axis. Furthermore, a comprehensive review of the literature reveals substantial evidence supporting the positive effects of yoga on infertility factors. These include oxidative stress (OS), oxidative DNA damage (ODD), epigenetic changes, hormonal balance, ovarian function, menstrual irregularities, and stress reduction. In summary, yoga emerges as a promising adjunctive therapy for infertility, demonstrating the potential to mitigate key factors influencing reproductive success. Although preliminary evidence indicates the positive effects of yoga on infertility, further clinical research is imperative to define specific benefits, molecular mechanisms associated, optimal protocols, and long-term effects in infertility treatment plans.

Purpose: Untreated stress, anxiety, and depression during the perinatal period can lead to adverse maternal and infant outcomes. Yoga, the practice of body-mind-spirit techniques has been shown to reduce stress, anxiety, and depression.

Aims: The aim of the study was to examine the feasibility and limited efficacy of the 4-week practice of pregnancy tele-yoga module (PTYM) delivered and monitored through an online platform.

Methodology: A multicentric, open-label, exploratory study was conducted in the antenatal clinics (ANCs) of three tertiary care hospitals in India. Pregnant women between 13 and 32 weeks of gestation were invited to participate. PTYM was taught by the trained research staff. A YouTube link demonstrating the PTYM developed by the researchers was shared with consenting participants. Using the Yoga Performance Assessment (YPA), research staff monitored the online performance of the PTYM. Pre- and postintervention, women were assessed using the Depression, Anxiety, and Stress Scale-21 (DASS-21).

Results: Preintervention, among 162 consented pregnant women, anxiety (62.34%) was the most common mental health condition, followed by stress (55.55%) and depression (45.67%). YPA at the end of week 1, week 2, week 3, and week 4 was 19.45, 21.35, 24.15, and 28.45, respectively. Postintervention anxiety, stress, and depression persisted in 19.78%, 11.44%, and 10.41% of women. Pregnant women with stress (DASS-21 ≥15; n = 90), anxiety (DASS-21 ≥8; n = 101), and depressive (DASS-21 ≥10; n = 74) symptoms after undergoing 4 weeks of PTYM reported significant reduction in the scores.

Conclusion: The current study demonstrated the feasibility and limited efficacy of PTYM in ANCs of a tertiary care hospital in India.

Background: Depression has been expected to be the second-leading cause of disability, followed by autism, attention and hyperactivity disorder, and learning disorder. Yoga therapy has found to be beneficial in managing psychiatric disorders.

Aim: The present study undertakes a scoping review of research on yoga therapy in psychiatric disorders among children and adolescents.

Methods: Online database was used to identify papers published 2004-2023, from which we selected 11 publications from the United States, Canada, Iran, India, and Australia that used yoga therapy as a primary outcome variable among participants aged 3 years or older.

Results: The papers reviewed were randomized controlled trials. All studies examined yoga therapy, but one study used mindfulness-based therapy and used few techniques of yoga therapy. The studies examined the effect of yoga therapy on early childhood and adolescence on various psychiatric symptoms such as stress, inattention, hyperactivity, anxiety, depression, and many more.

Conclusion: While the quality of studies is generally high, research on yoga therapy among children and adolescents with psychiatric disorders would benefit from careful selection of methods and reference standards, suitability for yoga therapy, and prospective cohort studies linking early childhood exposures with yoga therapy outcomes throughout childhood and adolescence.

Stress is an enormous concern in our culture because it is the root cause of many health issues. Yoga asanas and mindfulness-based practices are becoming increasingly popular for stress management; nevertheless, the biological effect of these practices on stress reactivity is still a research domain. The purpose of this review is to emphasize various biosignals that reflect stress reduction through various yoga-based practices. A comprehensive synthesis of numerous prior investigations in the existing literature was conducted. These investigations undertook a thorough examination of numerous biosignals. Various features are extracted from these signals, which are further explored to reflect the effectiveness of yoga practice in stress reduction. The multifaceted character of stress and the extensive research undertaken in this field indicate that the proposed approach would rely on multiple modalities. The notable growth of the body of literature pertaining to prospective yoga processes is deserving of attention; nonetheless, there exists a scarcity of research undertaken on these mechanisms. Hence, it is recommended that future studies adopt more stringent yoga methods and ensure the incorporation of suitable participant cohorts.

Background: Experiential avoidance (EA) and mindfulness are the two important transdiagnostic process and outcome variables in psychological formulation and treatment. While smartphones have a large utility value, they also have the potential for adverse impacts on functioning. Studies have separately shown associations among EA, dispositional mindfulness (DM), and problematic smartphone use (PSU). However, there is a lack of study exploring the associations and mediation relationship among these variables together in an Indian context. The current study aims to explore the associations of PSU, DM, EA, and sociodemographic factors; including the mediating effect of EA between DM and PSU in the Indian adult context.

Methods: Four hundred and thirty-four participants (M age = 25.4, standard deviation = 2.6, 58.8% females) were recruited for an online survey using a cross-sectional design. Data were collected using sociodemographic questionnaire, Smartphone Addiction Scale-Short Version, brief EA scale, and Mindfulness Attention Awareness Scale. Statistical analyses comprised multiple regression, mediation analysis, and significance in sociodemographic variables.

Results: Both EA and DM significantly predicted PSU with a 37% variance; however, DM had an inverse relationship. EA as a mediator could account for a quarter of the effect, P_M = 24.4%, ab = -0.14, 95% CI^cs (-0.19, -0.09).

Conclusion: The current study implicates the monitoring and treatment planning for PSU from a transdiagnostic perspective in the Indian context.

Background: Yoga therapy (YT) as an adjunct treatment has reportedly been demonstrated to offer clinical benefits in major depressive disorder (MDD). Although a few biological pathways are suggested to mediate the effects of yoga, the precise mechanistic basis remains unknown. Oxidative stress pathway activation has consistently been linked to the pathobiology of MDD. Whether YT has a modulatory effect on the oxidative stress pathway in MDD is not adequately understood.

Aim and objectives: In this study, we examined the impact of a course (3 months) of yoga as an add on therapy on the markers of the oxidative stress pathway in MDD patients.

Methods: Thirty-three MDD patients were randomized to the YT (n = 16) and waitlist control (WC) (n = 17) groups. Colorimetric estimation of the plasma malondialdehyde (MDA) and total antioxidant (AO) levels was performed in all the study participants using commercially available kits at the baseline and after 3 months.

Results: A significant reduction of plasma MDA levels was observed in MDD patients of YT group (P = 0.05) after 3 months of YT. Notably, the plasma MDA levels also decreased in MDD patients of WC group (P = 0.015) after the trial period. In addition, levels of total AO showed a trend toward significance only in MDD patients after 3 months of YT (P = 0.07). Conclusion: The current study suggests that the benefits of YT might be mediated through its modulatory role on the oxidative stress pathway in MDD.

The optic nerve comprises approximately 1.2 million axons of retinal ganglion cells and is vulnerable to degeneration due to a myriad of causes. While traditional treatments have been the cornerstone of ocular care, emerging evidence highlights the benefits of integrative approaches, which can be used as an adjunct in the management of optic neuropathy. Yoga is a mind-body energy medicine encompasses physical postures, breath control, and meditation. Currently, it has gained attention for its holistic effects on well-being, by promoting health, preventing onset of diseases, adjunct in disease management, and for its rehabilitative potential. In addition, the underlying mechanisms through which yoga exerts its therapeutic influence, evaluates clinical outcomes, and explores potential synergistic effects with conventional treatments remain largely unexplored. Neuroprotective mechanisms of yoga, such as enhancing retinal ganglion cell function, reducing oxidative stress, coupled with its ability to modulate inflammatory processes and improve circulation, contribute to its potential benefits in visual health. Analysis of clinical studies reveals promising outcomes, including improvements in visual acuity, visual fields, quality of life, and functional outcomes in individuals with optic neuropathy and ocular manifestations who undergo yoga intervention (especially dhyaan) with awareness of breath. Furthermore, the integration of yoga with conventional treatments and complementary modalities unveils the possibilities of multidisciplinary approaches in ocular care that need evaluation. By unraveling the role of yoga intervention in ocular health, this review provides valuable insights for clinicians and researchers, fostering a deeper understanding of the mind-body connection and paving the way for enhanced visual health outcomes. Embracing yoga as an adjunctive therapy may has the potential to revolutionize the management of optic neuropathy and ocular manifestations, offering individuals a holistic approach to optimize visual well-being, reduce comorbid depression and caregiver burden, and improve overall quality of life.

Introduction: Yoga is emerging as one of the holistic approaches to respiratory diseases. The scope of yoga is expanding in communicable diseases with physical, mental, and societal benefits.

Aim and objective: The present study aims to evaluate the effect of integrated yoga as an adjuvant therapy to the National Tuberculosis Elimination Programme (NTEP) on assessing health-related Quality of Life (QoL) in patients with pulmonary tuberculosis (PTB).

Setting and design: A randomized controlled trail study was conducted in a tertiary care teaching hospital.

Methodology: The study screened 826 PTB patients; 72 patients were found suitable and agreed to participate. The PTB patients were randomly assigned to either a yoga group (n = 36) or a control group (n = 36) using the sequentially numbered opaque sealed envelope technique. The control group received standard-of-care treatment as per NTEP, and the yoga group practiced 45 min of integrated yoga for 8 weeks along with standard of care. The World Health Organization Quality of Life (WHOQOL-BREF) questionnaire was used to collect the data at baseline and after 8 weeks of intervention.

Results: The results of within-group comparisons in both the groups showed that there was a significant improvement in physical (P < 0.01), psychological (P < 0.01), and social (P < 0.01), with P ≤ 0.05 being considered statistically significant except environmental domain. Between groups, analysis shows that in the preintervention, there was no difference between the yoga and control group as P > 0.05. After the yoga intervention, there was an enhancement in QoL scores with three domains except the environmental domain (P = 0.28).

Conclusion: The study evidence supports the use of yoga as a complementary therapy for the NTEP in patients with PTB may improve their QoL.
