CONTEXT: Research on the effect of Thoppukaranam is limited despite it being practiced as a form of worship to the elephant-headed deity Lord Ganapati and punishment in schools. AIMS: The purpose of this study was to examine the effect of Thoppukaranam on selective attention and psychological states in a sample of young adults. SETTINGS AND DESIGNS: A randomized self-as-control within subjects design was employed. Thirty undergraduate students (4 females and 26 males) from a residential Yoga University in Southern India were recruited for this study (group mean age +/- standard deviation, 20.17 +/- 2.92). MATERIALS AND METHODS: The d2 test, State Anxiety Inventory-Short Form and State Mindful Attention Awareness Scale (SMAAS) were used to measure cognitive performance and psychological states. Assessments were made in three sessions: Baseline, control (squats), and experimental (Thoppukaranam) on 3 separate days. STATISTICAL ANALYSIS USED: Data were analyzed using one-way repeated measures analyses of variance between three sessions, that is, baseline, squat, and Thoppukaranam. RESULTS: There was a significant improvement in all measures of the d2 test of attention (TN, E, TN-E, E%, and concentration performance) and state mindfulness after Thoppukaranam. Further state anxiety reduced significantly after the experimental session. CONCLUSIONS: These findings indicate Thoppukaranam results in enhancement of cognitive functioning and psychological states.

Background: There is very little evidence available on the effects of yoga-based breathing practices on response inhibition. The current study used stop-signal paradigm to assess the effects of yoga breathing with intermittent breath holding (YBH) on response inhibition among healthy volunteers.Materials and Methods: Thirty-six healthy volunteers (17 males + 19 females), with mean age of 20.31 ± 3.48 years from a university, were recruited in a within-subject repeated measures (RM) design. The recordings for stop signal task were performed on three different days for baseline, post-YBH, and post yogic breath awareness (YBA) sessions. Stop-signal reaction time (SSRT), mean reaction time to go stimuli (go RT), and the probability of responding on-stop signal trials (p [r/s]) were analyzed for 36 volunteers using RM analysis of variance. Results: SSRT reduced significantly in both YBH (218.33 ± 38.38) and YBA (213.15 ± 37.29) groups when compared to baseline (231.98 ± 29.54). No significant changes were observed in go RT and p (r/s). Further, the changes in SSRT were not significantly different among YBH and YBA groups. Conclusion: Both YBH and YBA groups were found to enhance response inhibition in the stop-signal paradigm. YBH could be further evaluated in clinical settings for conditions where response inhibition is altered.

Stress is recognised as the most challenging issue of modern times. Contemporary science has understood this phenomenon from one aspect and Indian philosophy gives its traditional reasons based on classical texts. Modern science has recently proposed a concept of perseverative cognition (PC) as an important reason for chronic stress. This has shown how constant rumination on an unpalatable event, object or person leads to various lifestyle disorders. Similarly classical yoga texts like the Taittiriya Upanishad, the Bhagavad Gita, and the Yoga Vashistha describe stress in their unique ways. We have here attempted a detailed classification, description, manifestation, and development of a disease and its management through these models. This paper in a nutshell projects these two models of stress and shows how they could be used in future for harmonious management of lifestyle disorders.
