Quality of sleep of university students who use caffeine
Abstract
Introduction: Sleep deprivation is considered a public health problem and is directly related to several academic and health consequences. Caffeine is the main substance ingested by university students who aim to improve performance in their studies, however caffeine can cause harm due to its effects on the central nervous system, impairing the quality of sleep. Objective: To evaluate the quality of sleep of university students who use caffeine. Materials and methods: this is a descriptive and quantitative research that evaluated the responses to an online questionnaire on food frequency and sleep quality among university students from different courses and periods of study, aged between 18 and 59 years old, both sexes, with statistical data analysis. Results: The main foods eaten by university students every day are pure coffee, coffee or chocolate milk and other foods with chocolate and drinks such as sodas, cola and guarana are consumed once a week. Conclusions: this study concluded that the main food containing caffeine consumed by students is pure coffee and coffee with chocolate or coffee. Further work with a larger number of university participants is recommended to analyze the association of caffeine consumption with quality of sleep using standardized instruments.
