Psychological parameters
The present study did not detect any significant changes in affect (positive and negative), vitality, and perceived stress after regularly performing the WHM.To the best of our knowledge, no previous studies have addressed the effects of regularly performing the WHM on these psychological outcomes. Only, Petraskova et al.In the study by Huttunen et al.Meditation has also demonstrated promising results in reducing psychological distress across different populations and settings and can be effective in enhancing vitalityIt is unclear why the present intervention did not induce positive psychological effects. However, it is possible that the considerable differences in interventions applied, and participants included may account for the differences. Furthermore, the intervention period of previous studies was considerably longer. It can be speculated that longer interventions may be necessary to produce more substantial changes in psychological parameters. Moreover, it cannot be ruled out that the combination of the different components of the WHM may have blunted the effects of each other. Further research is needed to determine the effects of regularly performing the WHM on psychological outcomes.
