Tokyo serves as the specific geographic location for a study cohort of university students whose sleep quality and cognitive performance were analyzed in [1], [2], and [3]. Measurements of sleep duration, efficiency, and PSQI scores for these university students were specifically recorded in Tokyo as detailed in [4], [5], and [6], highlighting the city's role in the research described in [7].

measurementUniversity students in Tokyo reported significantly poorer sleep quality (Mean PSQI = 9.2, SD = 3.0) compared to university students in London (Mean PSQI = 7.8, SD = 3.3) with a p-value < 0.001 and Cohen's d = 0.44.
claimA study investigating the impact of sleep quality on cognitive functions among university students collected data from 400 participants, with 200 students from Tokyo, Japan, and 200 students from London, UK.
measurementActigraphy data showed that university students in Tokyo had lower sleep efficiency (82.5 ± 7.0%) compared to university students in London (87.5 ± 8.0%) with a p-value < 0.001 and Cohen's d = 0.67.
measurementActigraphy data showed that university students in Tokyo had shorter sleep duration (6.1 ± 1.1 hours) compared to university students in London (6.9 ± 1.3 hours) with a p-value < 0.001 and Cohen's d = 0.63.
claimA study examining the impact of sleep quality on cognitive functions among university students in Tokyo and London revealed significant negative associations between sleep quality and various cognitive domains.
claimThe study of 400 university students in Tokyo and London found significant negative correlations between Pittsburgh Sleep Quality Index (PSQI) scores and cognitive performance, indicating that poorer sleep quality correlates with diminished cognitive abilities across domains.
referenceThe study emphasizes the essential impact of sleep quality on cognitive functioning in university students and identifies notable cultural differences between Tokyo and London that affect sleep patterns and mental health outcomes.
