Abstract

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 21.4 years).

METHODS:

It was a 14-day experiment. For the first 7 days, all participants consumed caffeinated coffee. In the following 7 days, 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.
