Objective: To examine medical students' engagement in wellness activities and evaluate the effects of biofeedback and structured napping on measures of stress, burnout and wellbeing. Method: A randomized trial of heart-rate variability (HRV) biofeedback and structured napping used by pre-clinical medical students at the University of Central Florida College of Medicine compared with a control group was conducted. Baseline measurement occurred in August 2016 with the follow-up period in March 2017. To measure biofeedback, participants used Heartmath Biofeedback® with Inner Balance® software to record HRV measurements while they engaged in self-guided breathing three times weekly. The biofeedback device connected to participants' iPhone or iPad with a sensor that clipped to users' earlobes. HRV recordings were stored in a heart-cloud database, and participants had the option to share their recordings with the researchers. Participants used sleep pods (MetroNaps Energy Pods®) to engage in 20-minute structured naps three times weekly. Participants completed six psychosocial self-report questionnaires at baseline (T1) and two follow-up points (T2, T3). The questionnaires included the Interpersonal Reactivity Index; Perceived Stress Scale; Quality of life scale; Oldenburg Burnout Inventory; and the Physician Well-Being Index. Results: Forty-two students enrolled in the study. Throughout the study, participants recorded 276 structured naps lasting approximately 20 minutes in duration and shared 24 personalized biofeedback recordings. Conclusions: Promotion of structured napping offers promise as an institution-initiated wellness intervention to promote medical students' mental health and wellbeing. HRV biofeedback warrants further study given the lack of conclusive findings in this study.
