Brief summary

Background: Emergency doctors face a highly stressful work environment during night shifts. Long-term night shift work can lead to sleep deprivation, fatigue accumulation, and disruption of the biological clock, which may affect doctors' work efficiency and physical and mental health. There are various health interventions for night shift doctors, one of which is an interesting practice of carrying an apple as a symbol of the night shift deity to relieve anxiety and improve work efficiency. Although this behavior is not supported by sufficient scientific evidence, it has become a common habit among some doctors during night shifts due to its simplicity, low risk, and ritualistic nature. Objective: To assess whether carrying an apple during night shifts can significantly reduce fatigue, decrease work intensity, and enhance work experience for emergency doctors. Design: Single-center, open-label, randomized controlled trial. Participants: several doctors with a total of 60 emergency working night shifts. Primary Outcome: Average number of patients per night shift. Sample Size: The study plans to recruit several doctors with a total of 60 emergency night shifts and randomly assign them to the experimental group and the control group. One doctor can be randomized for many times.
