Abstract: Background Insomnia and daytime sleepiness, influenced by lifestyle factors impacting overall well-being and academic performance, are commonly observed among students. The study investigates associations between insomnia, daytime sleepiness, and lifestyle factors such as physical activity and coffee consumption among Turkish public health students. Material and methods A cross-sectional study was conducted among 414 students from a Turkish university. An online survey was used, including demographic questions, coffee consumption, insomnia, and physical activity. Data was analyzed using descriptive statistics and linear regression analysis. Results 92.2% of men and 86.4% of women drank coffee daily. 21.7% of women and 7.8% of men engaged in regular physical activity. 62.6% of women and 49.4% of men reported 7-8 hours of sleep, while 41.6% of men and 31.2% of women reported less than 7 hours. Clinical insomnia was found in 32.5% of men and 37.4% of women. Severe insomnia affected 15.6% of men and 3.9% of women. Significant daytime sleepiness was noted in 9.1% of men. Age and insomnia index were significant predictors of daytime sleepiness (R²=0.057; F=4.13; p=0.000). Conclusions The prevalence of insomnia and daytime sleepiness among students highlights the need for interventions promoting sleep hygiene. Strategies should address lifestyle factors and emphasize sleep hygiene for academic performance.
