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
