Item Effect of suddhi kriya based yoga program on allergic rhinitis - a randomized controlled study(S-VYASA, 2025-01-16) Ripudaman Singh Chauhan; Dr. Rajesh S. K.BACKGROUND Allergic Rhinitis (AR) is a common IgE (immunoglobulin-E) mediated upper respiratory tract inflammation, causing symptoms like runny nose, sneezing, and nasal obstruction, with a global prevalence of 20%-40%. While not life-threatening, AR significantly impairs daily functioning. Yoga interventions have shown promise in improving lung capacity, nasal airflow, and AR symptoms, potentially through anti-inflammatory mechanisms. Yoga can downregulate pro inflammatory cytokines, upregulate anti-inflammatory cytokines, activate the HPA axis, and stimulate the vagus nerve, leading to reduced TNF-alpha, NF-κB, CRP, and cortisol levels. As a frequently used complementary and alternative therapy, yoga, particularly Hatha yoga, with its Shuddhi Kriya cleansing techniques and breathing exercises, appears to positively influence both the immune and respiratory systems, offering potential benefits for AR management. AIMS AND OBJECTIVES Prevalence Study: The aim of this study was to assess the prevalence and impact of Allergic Rhinitis (AR) among college students in Vadodara city. Intervention Study: The primary aim of this research is to evaluate the effectiveness of a Shuddhi Kriya-based yoga program in managing allergic rhinitis. METHODS SUBJECTS AND DESIGN Prevalence Study: In a cross-sectional study conducted among college students in Vadodara city, Gujarat, a total of 1337 students were included through a cluster sampling method. Responses were recorded using the SFAR (Score for allergic rhinitis) scale in conjunction with a semi- structured questionnaire. Intervention Study: In a randomized controlled trial (RCT), the study involved 60 individuals who had been experiencing moderate to severe chronic allergic rhinitis for over a year. These participants were randomly assigned to either a yoga or a control group. Seven patients were later withdrawn from both the yoga and control groups, resulting in a final sample of 53 patients (27 in the yoga group and 26 in the control group). Over the course of eight weeks, the yoga group engaged in the SKYP module for approximately 60 minutes each day, four days a week. The protocol included a combination of yogic Shuddhi Kriyas, asanas, loosening exercises, breathing exercises, pranayama, along with yogic counseling and lectures. Measurements of the nasal symptom score (TNSS), the Mini-rhinoconjunctivitis quality of life questionnaire (mini RQLQ), peak expiratory flow rate (PEFR), and peak nasal inspiratory flow (PNIF) were conducted both before and after the 8-week intervention period. DATA EXTRACTION & DATA ANALYSIS Prevalence Study: In the cross-sectional study, data collection was facilitated through Google Forms, structured into three parts. The initial section captured demographic details, the second part consisted of the SFAR form, and the final section contained a semi-structured questionnaire. Diagnosis of AR was based on the SFAR scoring system, which comprises 8 questions and ranges from 0 to 16. A cut-off of SFAR≥7 was utilized to define the presence of AR, with a sensitivity of 74% and specificity of 83% for SFAR≥7. Intervention Study: For the RCT, data recorded on questionnaire sheets was transferred to an Excel spreadsheet, and various variables were analyzed across different domains. The statistical analysis was carried out using R statistical software, version 4.0.2. Normality tests were performed on both baseline and post-trial data. For normally distributed variables, a parametric independent sample t-test was employed to assess significance, while the non-parametric Mann Whitney U test was utilized for non-parametric data. In cases where baseline matching between the yoga and control groups was lacking, difference scores were computed for the relevant variables. RESULTS Prevalence Study: Based on the SFAR (Short Form for Allergic Rhinitis) scale, a total of 257 students, constituting 19.22% of the participants, scored SFAR≥7, meeting the criteria for diagnosing Allergic Rhinitis (AR). Among those diagnosed with AR, the mean age was 20.37±2.04 years. Within this group, 168 (65.37%) were female, with a mean age of 20.29±1.86 years, while 89 (34.63%) were male, with a mean age of 20.51±2.33 years. Notably, participants with an SFAR score of ≥7, indicative of AR, exhibited common symptoms such as sneezing (84.05%), runny nose (71.98%), nasal congestion (71.21%), and eye itching or epiphora (78.21%), all of which showed significant differences when compared to the non-AR group (P<0.01). Among the AR-positive participants, 100 (38.91%) had Perennial Allergic Rhinitis (PAR), while 133 (51.75%) had Seasonal Allergic Rhinitis (SAR). Among the SFAR≥7 (AR positive) group, 227 (88.33%) identified house dust and pollen as triggering agents, while 30 (11.67%) couldn't identify specific allergens. Additionally, the questionnaire revealed that 209 (81.32%) participants in the AR-positive group were aware of their allergies, and 52 (20.62%) had undergone allergy testing (IgE or SPT), with 38 (73.08%) receiving positive results. Notably, among male participants, 13 (14.60%) reported no effect of AR on their academic activities, while 24 (27%) experienced a mild effect, 38 (42.70%) a moderate effect, and 14 (5.70%) a severe effect. In contrast, among female students, 32 (19%) reported no effect, 37 (22%) a mild effect, 75 (44.60%) a moderate effect, and 24 (14.30%) a severe effect on their academic activities due to AR. Intervention Study: The implementation of the Shuddhi Kriya-based yoga intervention resulted in significant improvements in the Total Nasal Symptom Score (TNSS) 12-hour morning rating. Notably, there was a substantial reduction in the score for nasal drainage (z = -2.67, p = 0.007) and the overall total symptom score (z = 3.16, p = 0.002) compared to the control group. However, no statistically significant differences were observed in other symptom categories, including nasal blockage, nasal itching, sneezing, and poor sleep (all p > 0.05). In the two-week assessment of the Total Nasal Symptom Score (TNSS), the yoga group exhibited significant improvements in all domains of nasal symptoms when compared to the control group. Notably, there were substantial reductions in nasal congestion (z = -3.43, p = 0.001), nasal drainage (z = - 3.39, p = 0.001), nasal itching (z = -3.51, p = 0.001), sneezing (z = -3.89, p = 0.001), and difficulty in sleeping (z = -2.13, p = 0.033). The overall total TNSS also showed significant improvement (z = -4.71, p = 0.001). The participants in the yoga group, experienced a significant reduction in symptom scores, as measured by the Mini Rhinoconjunctivitis Quality of Life Questionnaire (Mini RQLQ), across all five domains. Specifically, there were notable reductions in activity (z = -4.89, p = 0.001), practical problems (z = -4.18, p = 0.001), other symptoms (z = - 3.21, p = 0.001), nose symptoms (t = -4.83, p = 0.001), and eye symptoms (t = -4.83, p = 0.001). The total score also demonstrated a considerable enhancement (t = -3.01, p = 0.004). Regarding symptom severity, both ocular and nasal symptoms improved significantly in the yoga group compared to the control group, as evidenced by the Visual Analog Scale (VAS) scores (ocular symptoms: z = -4.19, p = 0.01; nasal symptoms: z = 4.71, p = 0.01). In terms of respiratory function, the Peak Nasal Inspiratory Flow (PNIF) exhibited a substantial improvement in the yoga group compared to the control group (z = 2.76, p = 0.006), while the Peak Expiratory Flow Rate (PEFR) did not show a significant improvement (t = 1.95, p = 0.056). CONCLUSION Prevalence Study: In conclusion, our study found that allergic rhinitis (AR) is common among college students in Vadodara city, with Seasonal Allergic Rhinitis (SAR) being more prevalent than Perennial Allergic Rhinitis (PAR). Despite high awareness, only a minority had undergone allergy testing. Many students with AR experienced comorbidities, impacting their academic activities significantly. This highlights the need for public health policies addressing respiratory health and early diagnosis. Future research should identify risk factors to inform targeted interventions. Intervention Study: In conclusion, the Shuddhi Kriya Yoga Program (SKYP) stands out as a promising integrative approach for managing allergic rhinitis, offering substantial improvements in both physical symptoms and overall quality of life. This comprehensive program, which includes a unique combination of Hatha Yoga's Shat Kriyas, asanas, pranayama, and relaxation techniques, has demonstrated significant efficacy in reducing nasal symptoms and enhancing the well-being of individuals dealing with moderate to severe allergic rhinitis. Its holistic approach, with a focus on stress reduction and non-invasive healthcare solutions, suggests its potential value in the treatment of this condition. This study provides a foundation for further research and the potential integration of yoga-based interventions into standard treatment protocols for allergic rhinitis.Item Yoga for psycho-spiritual well-being of French professionals(S-VYASA, 2025-01-16) Pascal Papillon; Dr. Rajesh S. K.INTRODUCTION The mental and psychological health of French professionals is a concern, with high rates of conditions such as anxiety, depression, burnout, and stress. While yoga has been shown to have positive effects on physical, mental, and spiritual health, there is a lack of research on its effects specifically among French professionals. Due to cultural differences, it is important to investigate the potential benefits of yoga for this population and develop culturally-appropriate interventions. LITERARY REVIEW The aim of this literature review study was to evaluate the existing scientific literature on Karma Yoga, with a focus on understanding its potential benefits for promoting human excellence. The review of literature suggests that the application of Karma Yoga can be applied in a variety of settings to promote human excellence, including in the areas of business and work, transformational leadership, moral development, and spirituality. Further, literature review study found that spiritual well-being, mindfulness, emotion regulation, stress, and happiness are closely related and can be affected by various factors such as work-life balance, work demands and personal factors. The research suggests that interventions that focus on holistic well-being, including spiritual well-being, mindfulness, emotion regulation, stress, and happiness may be more effective in promoting overall well-being among professionals. AIMS The three studies aimed to provide a comprehensive examination of the relationship between spiritual health and psychological well-being, the presumption of cross-cultural similarity, and the effectiveness of a yoga-based intervention on these factors. The purpose of first study was to investigate the correlation between spiritual well-being, mindfulness, and emotion regulation among a group of young emerging French professionals. Additionally, the second study aimed to compare and contrast the mindfulness, job satisfaction, and happiness levels, as well as the significance of spirituality and religion, among Indian and French professionals. Furthermore, the third study aimed to assess the impact of yoga-based interventions on the psycho-spiritual well-being of French professionals for a period of 8 weeks, with a subsequent evaluation one month later. METHODS SUBJECTS AND DESIGN The first study used an online cross-sectional survey design to observe the relationship between spiritual health and psychological well-being among a sample of 421 participants recruited from universities in Strasbourg, France. The age range of participants in this study was 18 to 28 years with a mean age of 20.77 years (SD=2.22). The second study used a similar design to test the presumption of cross-cultural similarity among a sample of 214 IT professionals from France and India. The sample from France had a mean age of 42.36 years (SD=10.46 years) and the sample from India had a mean age of 38.25 years (SD=8.68 years).The third study used a two group pre/post-intervention design to examine the effectiveness of a yoga-based intervention on spiritual health and psychological well-being among a sample of 67 participants, with 33 in the yoga group and 34 in the control group. The mean age of the control group was 47.8 (9.5) and the mean age of the yoga group was 50.3 (7.2). ASSESSMENT TOOLS The study utilized measures to evaluate the emotional regulation, mindfulness, spiritual well being, stress, happiness, satisfaction at work and importance of spirituality/religion among professionals. The measures that were used in the study were: The Emotion Regulation Questionnaire, The Freiburg Mindfulness Inventory (FMI), The Spiritual Well-being Questionnaire (SWBQ), The Perceived Stress Scale, The Subjective Fluctuating Happiness Scale, The Subjective Authentic-Durable Happiness Scale, in addition to assessments of satisfaction at work and the importance of spirituality/religion. DATA EXTRACION AND ANALYSIS All statistical analyses were performed using the statistical package JASP and R Software. Pearson correlations were used to examine the association between the variables of interest. Multiple regression was run to predict the outcome variables based on the predictor variables. The independent samples t-test was used to compare differences between groups and two-way mixed ANOVA was used to analyze the interaction effects between the independent variables. RESULTS The results of three different studies can be summarized as: The first study results indicate that there is a strong positive correlation between self-reported spiritual health and mindfulness. Additionally, the results show a significant association between spiritual health and emotional processes. Moreover, the study found that spiritual dissonance is negatively related to spiritual health and mindfulness. The findings of second study revealed that there were no significant differences in levels of mindfulness, satisfaction at work, fluctuating happiness and authentic-durable happiness between Indian and French IT professionals. Furthermore, the study found that there was a similar pattern of intercorrelations between these variables among the two groups, which could be seen as an indication of cross-cultural agreement. However, the study also found that Indian IT professionals had higher levels of importance placed on religion and spirituality when compared to French IT professionals. The results of the third study suggest that after an 8-week yoga-based training intervention, French professionals experienced a significant reduction in stress levels, an improvement in emotion regulation(reappraisal domain), an increase in mindfulness, an enhancement in spiritual well-being, and an improvement in authentic-durable happiness. CONCLUSIONS In conclusion, the first study suggests that various aspects of spirituality can positively impact the well-being of emerging professionals. The second study emphasizes the need to take into account cross-cultural factors when studying well-being in the workplace, particularly in terms of the significance placed on religion and spirituality. The third study presents evidence for the efficacy of yoga in enhancing psycho-spiritual well-being among French professionals, but additional research is necessary to fully understand the underlying mechanisms and to evaluate other potential methods of measuring well-being.
