Abstract
Sleep is one of the most basic biological requirements, yet it is often treated as negotiable during medical education. Medical students commonly move between lectures, examinations, clinical duties, commuting, study sessions and social
responsibilities, creating a routine in which sleep may be shortened or fragmented. This narrative review examines sleep quality among medical students and the factors associated with it, including academic workload, stress and anxiety, clinical schedules, electronic-device use, irregular routines, lifestyle habits and the learning environment. Evidence from large systematic reviews indicates that poor sleep quality is common in this population.
