Daily caffeine use and the sleep of college students

Abstract

The relationships between daily caffeine consumption and both habitual sleep duration and sleep satisfaction were assessed using the responses of 170 students. Essentially, our data replicated an earlier study, in that we found an inverse relationship between level of daily consumption of caffeinated drinks and habitual sleep duration and a nonsignificant relationship between caffeine use and sleep satisfaction. © 1983, The Psychonomic Society, Inc..
