Association Between Sleep Patterns and Academic Performance: Evidence from Sabaragamuwa University Arts Students, Sri Lanka Journal of Economics, Statistics, and Information Management, 4(2), 104-118 Abstract Students' well-being, academic performance, and cognitive memory all depend on getting enough sleep. However, today, insufficient sleep is a prominent problem in society. It also leads to various diseases. Thus, the purpose of this study is to examine the association between university students' sleep patterns and their academic achievement, with a particular emphasis on Bachelor of Arts candidates at Sabaragamuwa University of Sri Lanka. A structured Questionnaire was employed to collect primary data for the present investigation. This study employed a quantitative approach. For a sample of 112 university students, convenience sampling was used. In this case, the analysis method was chi-square, while additional methods were descriptive statistics. Additionally, sleep patterns were assessed using the Pittsburgh Sleep Quality Index (PSQI). According to the results obtained here, 68% of the 112 respondents were females, indicating that the majority of university student respondents were females. In the higher GPA categories, female students at Sabaragamuwa University perform better than male students, with ratings ranging from 18.7% very high and 35.1% high, while for male students, it is 21.6% very high and 41.3% high. Also, most students go to bed after 9:00 PM, and the association is highest between 10:00 PM and 11:00 PM; 62.1% of these students fall into the moderate GPA category. Late bedtimes (after 11:00 PM) are associated with higher percentages in both the high (52.3%) and poor (52.9%) GPA categories, indicating adverse effects on academic achievement. Additionally, the study demonstrates an association between GPA and sleep habits, including efficiency, duration, and quality of sleep. Encouraging university students to adopt healthy sleep habits through education, regular schedules, and counselling services is advised because sleep patterns have a major impact on academic performance
