Two hundred and seventy-seven medical students were invited to sign a written informed consent then responded to a structured questionnaire based on the Epworth Sleepiness Scale, demographic factors, Technology use, Cumulative Academic Grade (GPA), coffee consumption and sleeping pill use. The Chi-square and t-test were used to compare the students with excessive daytime sleepiness and those without the disorder and test the associated factors.

No significant statistical associations were evident between the daytime sleepiness and age, sex, technology use, sleeping pills, chronic diseases, coffee intake and the GPA, (P-value<0.05).
Conclusion: Excessive daytime sleepiness was prevalent among the medical students; no significant differences were detected between the students with this serious sleeping disorder and those without regarding demographic factor, Internet surfing, mobile phone texting, sleeping pills use, coffee consumption, and the cumulative grades.
