Background:Health University students are exposed to a significant level of pressure due to academic demands.  Their sleep pattern is characterized by insufficient sleep duration, delayed sleep onset, and occurrence ofnapping episodes during the day.

Objective: To examine the effects of sleep on the academic performance of students.

Methods: This is a cross–sectional self–administered questionnaire–based study. The participants were medical students, dental students and nursing students. The Pittsburgh Sleep Quality Index (PSQI) was used to identify sleep disorder and grade point average was recorded foracademic performance.

Results:When compared between the three streams, there was statistically significant difference on PSQI between the MBBS vs. B.Sc. Nursing students (0.032) and BDS vs. B.Sc. Nursing students (0.011). Also PSQI was statistically significant (less than 0.05) for all passed students (n=127) and the failed students (n=24).

Conclusion: Passing students has better sleep related parameters than failed students.
