University students, caffeine consumption and stress: Effects on sleep quality and daytime functioning
Frances O’Callaghan and Kyle Wyatt
Griffith University, Australia
Statement of the Problem: Poor sleep quality and excessive daytime sleepiness are positively associated with common mental
disorders such as depression, anxiety and somatoform disorders, as well as lapses in concentration and daytime tiredness.
These relationships are complicated among university students who have high caffeine consumption and high stress, both of
which affect sleep quality.
Methodology &Theoretical Orientation: This was a quantitative study involving 175 full-time university students from 17 to
25 years (mean=19.43, SD=2.06). Students completed an online questionnaire about their sleep quality, daytime functioning,
caffeine consumption and recent level of stress symptomatology.
Findings: Poor quality sleep was associated with diminished daytime functioning. Increased caffeine consumption influenced
daytime functioning by lowering the quality of an individual’s sleep. However, the relationship between quantity of caffeine
consumption and sleep was dependent on the time of day the caffeinated beverages were consumed. Increased stress was
related to both reduced sleep quality and reduced daytime functioning.
Conclusion: The findings highlight the implications for daytime functioning of university students not getting sufficient
quality sleep, and the role of lifestyle factors pertaining to caffeine use and stress.
