    COMPARATIVE STUDY ON THE IMMEDIATE EFFECTS OF SURYA AND CHANDRA NAMASKAR ON AUTONOMIC FUNCTION IN YOUNG ADULTS: A PARALLEL GROUP TWO-ARM STUDY
    (S-VYASA, 2026) Poornashri Umesh Angadi; Lehar Gupta; Shishira R.; Moulya K Appanna; Amit Kanthi
    BACKGROUND Surya and Chandra Namaskar are two dynamic yogic practice sequences rooted in the Indian traditional system. While the concepts of Surya (solar) and Chandra (lunar) are traditionally associated with activating and calming qualities, respectively, these associations are conceptual and not directly attributed to the structured practices in classical texts. The present study aimed to evaluate and compare the immediate effects of Surya Namaskar and Chandra Namaskar on autonomic and physiological parameters under controlled conditions. It was hypothesized that Surya namaskar will predominantly enhance sympathetic activation due to its dynamic nature, while Chandra Namaskar will promote parasympathetic dominance through slower, more controlled breathing and movements. Methods: A total of 48 healthy young adults (18–28 years) from S-VYASA University were recruited and randomly allocated into two groups: Group A (Surya Namaskar) and Group B (Chandra Namaskar). Both interventions were performed under identical morning conditions to minimize circadian influences. Outcome measures included heart rate variability, blood pressure, respiratory rate, galvanic skin response, and oxygen saturation. Pre- and post-intervention assessments were conducted to evaluate immediate autonomic changes. Result: No significant differences were observed between the two groups, suggesting that both practices do not have any comparable autonomic responses. Conclusion: The study demonstrated that both Surya Namaskar and Chandra Namaskar have independent immediate effect in autonomic functions in young adults. Both interventions showed a tendency toward sympathetic activation immediately post-practice, likely due to the dynamic nature of the sequences and the timing of measurements. Key Words: Surya namaskar, Chandra namaskar, Sun salutation, Moon salutation, Autonomic Variables, and yoga

    IMMEDIATE EFFECTS OF 90 DEGREE VERSUS 45 DEGREE INVERSION ON CEREBRAL HEMODYNAMICS AND HRV IN YOGA PRACTITIONERS: A RANDOMIZED CONTROLLED STUDY
    (S-VYASA, 2026) TARUN KUMAR S.; JANANI A P; AMSHUMAN R YADAV; Krishna Dwivedi
    Background: Inverted yoga postures are believed to influence cerebral circulation and autonomic nervous system regulation by altering gravitational blood flow dynamics. Practices such as 90° inversion and 45° inversion are traditionally used in yoga for promoting physiological balance and relaxation. However, scientific evidence comparing the immediate cerebrovascular and autonomic effects of different inversion angles remains limited. Aim: To investigate the immediate effects of two inversion postures—90° inversion and 45° inversion on cerebrovascular hemodynamics and cardiac autonomic function in healthy yoga practitioners. Methods: This randomized controlled study included 40 healthy yoga practitioners aged 18–35 years who had at least six months of yoga practice. Participants were randomly assigned to either the 90° inversion group or 45° inversion group. Each participant maintained the posture for approximately turn on I thought yesterday he only gave Roshan only completely3 minutes under supervision. Physiological assessments were conducted at three time points: baseline (supine rest), during the posture, and post-intervention recovery. Assessment: Cerebrovascular hemodynamic parameters—Peak Systolic Velocity (PSV), End-Diastolic Velocity (EDV), Mean Flow Velocity (MFV), Pulsatility Index (PI), and Resistance Index (RI)—were measured in the left Middle Cerebral Artery using Transcranial Doppler ultrasonography. Cardiac autonomic activity was assessed through heart rate variability (HRV) analysis, including time-domain and frequency-domain parameters. Results: Both inversion postures produced significant changes in cerebrovascular and autonomic parameters across the pre, during, and post phases. Mean flow velocity and end-diastolic velocity increased significantly during inversion, while pulsatility index and resistance index decreased, indicating improved vascular compliance. 90° inversion produced stronger autonomic and hemodynamic responses during the posture, whereas 45° inversion showed a more gradual recovery pattern with sustained reductions in vascular resistance. Conclusion: Both 90° inversion and 45° inversion significantly influence cerebral circulation and autonomic nervous system activity, though with different physiological patterns. 90° inversion induces stronger acute regulatory responses, while 45° inversion promotes a more sustained reduction in cerebrovascular resistance during recovery. These findings suggest that different inversion angles may offer distinct therapeutic applications for improving cerebrovascular regulation and autonomic balance.

    EFFECT OF YOGA ON CREATIVE THINKING IN MIDDLE SCHOOL RESIDENTIAL STUDENT
    (S-VYASA, 2025-08-19) Smita Rani; Rajesh Nair
    BACKGROUND: In today’s fast-changing world, creativity is essential for children to think flexibly, solve problems, and express themselves. However, studies report a decline in creativity during middle school, known as the “fourth-grade slump” (Torrance, 1967), often due to rigid academic routines and social pressures. Yoga, in which practices like asanas, pranayama, and mindful relaxation, and meditation have shown promise in improving focus, emotional balance, and brain function. Emerging research suggests yoga may also enhance creativity by reducing stress and supporting cognitive flexibility in young learners. AIMS AND OBJECTIVES: This study aimed to examine the effects of a structured yoga program on divergent thinking and creativity among middle school residential students. METHODS: A single-group pre-post design was employed. Forty healthy students aged 11–15 from PM SHRI Jawahar Navodaya Vidyalaya, Godda (Jharkhand, India) participated in a four week intervention comprising daily one-hour sessions of Asanas, Pranayama, Deep Relaxation Techniques, and Krida Yoga. Creativity was assessed using standardized measures evaluating Originality, Fluency, Flexibility, Verbal creativity, Non-verbal creativity, and Total creativity. RESULTS: Post-intervention scores showed statistically significant improvements in originality (P < .001; Cohen’s d = 0.9), verbal creativity (P < .001; d = 0.8), total creativity (P < .001; d = 0.8), fluency (P = .002; d = 0.5), and flexibility (P = .002; d = 0.6). No significant change was found in non-verbal creativity (P = 0.198; d = 0.2). CONCLUSIONS: The results suggest that regular yoga practice positively influences divergent thinking and creativity in middle school students. Yoga enhanced verbal creativity and cognitive flexibility, supporting its integration in educational settings. This highlights yoga’s potential as a holistic tool to foster students’ creative abilities, emotional balance, and mental well-being.

    EFFECT OF YOGA ON PHYSIOLOGICAL AND PSYCHOLOGICAL PARAMETERS RELATED TO OBESE CONDITION AND THE WELLBEING OF PARTICIPANTS AFFECTED BY OBESITY
    (S-VYASA, 2025-08-19) Jinal Mokariya; Rajesh Nair
    BACKGROUND Obesity, a global health crisis, has tripled since 1975 due to sedentary lifestyles, poor diets, and stress, leading to conditions like diabetes, heart disease, and depression. Conventional treatments often neglect psychological roots. This dissertation explores Yoga as a holistic intervention, focusing on the Integrated Approach of Yoga Therapy (IAYT). Through structured hospital-based programs, it assesses improvements in BMI, blood pressure, sleep, self-esteem, and emotional well being. Yoga’s mind-body practices offer a low-cost, accessible solution, especially vital for countries like India. The study aims to evaluate yoga’s potential as a sustainable model for both physical and psychological rehabilitation in obesity management. AIMS AND OBJECTIVES This study aims to evaluate the impact of the Integrated Approach of Yoga Therapy (IAYT) on the physiological and psychological parameters of individuals with obesity. As part of that, this study assessed the effect of IAYT on Body Mass Index (BMI), Blood Pressure, Sleep quality, Depression, Anxiety, and Stress in people suffering from obesity. METHODS Participant: A total of 52 participants aged between 25 and 60 years, clinically diagnosed with obesity (BMI ≥ 25 kg/m²), were selected using convenient sampling from Aarogyadhama, a yoga therapy hospital under S-VYASA University. Design: This study followed a single-group pre-post design Assessments: In this study, we assessed Body Mass Index (BMI), Blood Pressure (SBP & DBP), Pittsburgh Sleep Quality Index (PSQI), Depression Anxiety Stress Scales (DASS), WHO Quality of Life-BREF (Physical, Psychological, Social, Environmental) 1 Intervention: An integrated approach of yoga therapy (IAYT) program was administered for 2 weeks. The intervention included specific asanas (postures), pranayama (breathing techniques), kriyas (cleansing techniques), relaxation methods, and lifestyle modifications, including a special diet. Participants were guided regularly to maintain consistency and adherence to the protocol. Results: Participants showed significant improvements in various physical and psychological parameters, particularly in reduction of body weight, BMI, and improvements in sleep quality, stress levels, and overall well-being. Conclusions: IAYT was found to be effective in reducing obesity and improving physiological and psychological health markers when practiced consistently. It is a safe, holistic, and non pharmacological approach for managing lifestyle disorders like obesity.

    EFFECT OF CYCLIC MEDITATION ON STRESS LEVELS, ANXIETY, AND DEPRESSION IN HIGHER SECONDARY STUDENTS
    (S-VYASA, 2025-08-19) Tanisha Gupta; Rajesh Nair
    BACKGROUND In the current educational landscape, higher secondary students often grapple with immense academic pressures, peer expectations, and future uncertainties. These stressors have led to an alarming rise in psychological concerns such as stress, anxiety, and depression among adolescents, often compromising their academic performance and overall well-being. Addressing these issues through holistic and accessible practices has become increasingly necessary. One such intervention is Cyclic Meditation (CM), a structured yogic technique that blends physical postures with deep relaxation to regulate mental and emotional health. Though previous research has demonstrated CM’s benefits in adult populations, its application and effectiveness among school-going adolescents remain underexplored. AIMS AND OBJECTIVES This study aims to assess the effect of cyclic meditation on the stress, anxiety, and depression of higher secondary students. METHODS Participants and design A total of 62 school Students from VPS High School in Lonavala, Maharashtra, aged 15-18 years. This study will follow a single-group pre-post design. Assessments: Stress: Perceived Stress Scale (PSS) Anxiety: Depression Anxiety Stress Scale-21(DASS-21 Depression: Depression Anxiety Stress Scale-21(DASS-21 Sleep Quality: Pittsburgh Sleep Quality Index (PSQI) vi Intervention: Intervention (Cyclic Meditation practice) will be of the duration of 40 minutes and 5 days/week, for one month. CM consists of various steps like IRT (1Min), Centering, Ardhakati chakrasana, QRT (3Min), Vajrasana, Shashankasana, Ustrasana, DRT (14 Min) Results: Statistical analysis revealed significant improvements in three of the four targeted domains: Perceived stress levels decreased substantially (p < .001, Cohen’s d = 1.60), Depression scores showed a significant reduction (p < .001, d = 1.01), Anxiety levels dropped significantly (p < .001, d = 1.00), Sleep quality improved markedly (p < .001, d = 0.74). However, the DASS-21 stress subscale did not show statistically significant improvement (p = 0.108), possibly due to the instrument's sensitivity or the intervention duration. Conclusions: The findings suggest that Cyclic Meditation is an effective intervention for reducing perceived stress, anxiety, and depression, while simultaneously enhancing sleep quality among higher secondary students. Given its accessibility and holistic nature, CM can be feasibly integrated into school wellness programs. Future studies with control groups, longer follow-up periods, and diverse populations are recommended to further validate and expand upon these promising outcomes.
