Impact of yoga intervention on spiritual well being, sleep quality and guna in young widows: a randomized control trial

Objective of the study was to evaluate the efficacy of yoga on spiritual well being, sleep quality and Guna of young widows below 50 years of age. Eighty subjects were randomly allocated to two groups. Spiritual well being (SWB), Sleep quality (PSQI) and Guna (VPI) were assessed before and after eight weeks of intervention. The data analysis showed that quality of sleep was improved in both yoga group (P < .001) and control group (P=0.026). Religious well being scores were not significantly increased in both. Regarding existential well being, significant increment (P < .001) were observed in yoga group but, not (P = .075) in control group. There was significant increase (P = 0.001) in Sattva Guna only in yoga group. Rajas Guna score was decreased but not statistically significant in both the group. There were significant reduction in Tamas Guna scores in yoga group (P < 0.001) as well as in the control group (P = 0.032). This study suggests that yoga can improve spiritual well being, sleep quality and Sattva Guna, thus enhance balanced state of mind on young widows.
