| Popis: | Aim The aim of this study was to examine whether caffeine abstinence in the evening could improve the sleep quality of those who habitually consume coffee. Design A double-blind control group design (caffeine and caffeine-free groups). Setting A university. Subjects A convenience sampling of 10 students (mean age 21.4years). Methods It was a 14-day experiment. For the first 7days, all participants consumed caffeinated coffee. In the following 7days, subjects consumed caffeinated or decaffeinated coffee according to their assigned group. Measures Sleep–wake parameters, self-reported sleep quality and level of refreshment. Results There were no significant differences ( p >.05) among the data of the two groups identified. No significant changes ( p >.05) were found in the sleep quality of either group during the study. Conclusion This study confirms that caffeine abstinence in the evening might not be helpful in sleep promotion. It highlights the need to implement evidence-based practice in health promotion. |
