Multiple well-being surveys continue to highlight EM's challenges with sleep impairment due to the nature of the specialty. Despite evidence that lifestyle strategies effectively optimize performance and recovery, EM residents have variable lifestyle choices to prepare for overnight shifts. This prospective randomized controlled trial will examine whether a pre-shift personalized fatigue-mitigation lifestyle coaching (PFMLC) for EM residents on overnight shifts minimizes the effects of circadian rhythm disruptions on performance and recovery compared to those who receive one-time passive information on lifestyle practices. All participants will receive lifestyle strategy materials on fatigue mitigation to improve performance. Residents' self-reported and biometric data will inform PFMLC in the active arm.
