The transition from high school to university is characterized by changes in students' social and learning environments, potentially impacting sleep and learning behaviors. To examine the sleep characteristics of university students, this study aimed to (a) measure sleep in a living environment using a wearable tracker; (b) use a self‐administered questionnaire to examine the relationship between objective and subjective sleep; and (c) examine how psychological aspects are related to objective and subjective sleep. Fifty undergraduate and graduate students participated, with 310 sleep records obtained. The objective means total sleep time showed a moderately positive correlation with sleep quantity in the 3‐Dimensional Sleep Scale. Furthermore, we found that mental health, trait anxiety, and quality of life do not correlate with objective total sleep time but are significantly moderately correlated with subjective sleep quantity. The combination of wearable trackers and subjective reports may provide a more precise understanding of university students' actual sleep patterns and how different aspects of sleep behavior are associated with health outcomes
