Effect of the Knowledge of Biological Changes of Deep Breathing on the Stress Levels of Introverts

Abstract

This study investigates whether providing educational information about the biological effects of deep breathing enhances the effectiveness of the exercise in reducing stress levels. A total of 301 participants were randomly assigned to either a control group or an experimental group. Both groups completed a stress scale before and after practicing the 4-7- 8 deep breathing technique, but only the experimental group watched an educational video explaining the biological benefits of deep breathing prior to the exercise. Additionally, personality traits were assessed using the Mini-Markers Big Five scale to examine whether introverts would benefit more from the intervention. Results from independent samples t-tests and ANCOVA analyses showed no statistically significant differences in stress reduction between the groups or among introverts compared to extroverts. While previous research has shown that deep breathing can be effective in reducing stress, this study suggests that a single session combined with educational content may not be sufficient to enhance its impact. Limitations such as the online format and self-reported measures are discussed, and suggestions for future research are provided.
