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.
