Effects of an 8-Week Yoga-Based Physical Exercise Intervention on Teachers' Burnout

The purpose of this quasi-experimental study was to investigate the efficacy of an 8-week yoga-based physical exercise program to improve mental and emotional well-being and consequently reduce burnout among teachers. We considered yoga because it is a discipline that enhances body awareness and encourages the contact with nature and the respect for every form of life, with a view to a more sustainable and greener global system. We recruited 40 professional educators (40-47 years), teachers in a public high school who reported perceiving signs of stress and emotional discomfort. We randomly assigned the 40 professional educators to either an experimental yoga practice (similar to 60 min, twice a week) group (n = 20) or a control group (n = 20) that received a nonspecific training program (similar to 60 min, twice a week). At baseline and after training we administered the Maslach Burnout Inventory: Educators Survey (MBI-ES) and the State Mindfulness Scale (SMS) to assess teachers' perceived level of awareness and professional burnout. We found a significant Time x Group interaction for the MBI-ES and SMS, reflecting a meaningful experimental group improvement (p < 0.001). No significant pre-post changes were found in the control group. The results suggest that an 8-week yoga practice could aid teachers to achieve a greater body and emotional awareness and prevent professional burnout.
