Beyond the Rules of Thumb: The Need for Standardization of Brain Breaks in Medical Education

Abstract

I read with great interest the article by Ali et al. titled “Perception of Medical Students about Brain Breaks; Identifying the Gap to Improve Learning as per Sustainable Development Goal-4”, published in the September 2025 issue of the Pakistan Journal of Public Health. The authors have highlighted the importance of cognitive rest for medical students. In this study, more than half of the students indicated the need for a brain break after 45 minutes of academic activity. I am writing this letter to suggest that, even though it is a good starting point, further thorough research is needed to scientifically determine the optimal timings and durations of these brain breaks for medical students.

The authors also found that excessive brain breaks reduced the participants’ interest in the subject. This also points towards the existence of a “therapeutic window” for these brain breaks. Due to the intense academic environment of Pakistan, students face extremely high rates of burnout, affecting approximately 30% to 60% of medical students (1). This further highlights the need for more research to determine the optimal timings and durations of these very essential brain breaks.
