以下是一篇英语论文的摘要：
This paper investigates the relationship between sleep and academic performance among college students, using both self-reported measures and objective data. The results show a significant correlation between better sleep quality and higher academic performance. The study also found that students who obtained less than the recommended 7 hours of sleep per night experienced a decline in academic performance. The findings suggest that improving sleep habits may be an effective way to enhance academic performance among college students.
