The purpose of this study was to compare relationships among sleep habits, exercise habits, and academic achievement among Seventh-day Adventist college students. Fifty-nine students (26 men and 33 women) of various academic standings from Southern Adventist University participated in this study. The instrument used for this study was the Istueta Sleep (ISES). The ISES was specifically designed to measure different aspects of sleep and exercise in this study. Six hypotheses were tested in this study. The results suggest that greater exercise regularity, consistency in waking times, and amount of sleep during the weekend tend to yield a higher GPA. Future research should acquire participants' GPA from an official source, such as the student's transcripts, as well as through self-reporting. An experimental approach should be used to have more accurate results.
