Sleep is critical to physical health, mental well-being, attention, and creativity. During the week of final exams, however, fewer than 10% of undergraduate students maintain the recommended average of 8 hours/night (or, even the recommended minimum of 7 hours/night). For students completing multifaceted projects in studio-based majors (e.g., interior design, architecture, graphic design, studio art), anecdotal and questionnaire data suggest that the end-of-semester reduction in sleep duration may be even worse. One potential solution is to offer students an incentive to maintain healthy sleep durations. We offered interior design students, who were enrolled in a freshman-level graphics studio course, an optional extra credit incentive to maintain optimal sleep durations for five nights leading up to the due date of their final project. If participants maintained an average sleep duration of ≥ 8.0 hours for five nights, they would earn extra credit. By contrast, if they slept an average of 7.0-7.9 hours, there would be no grade change, and if they slept an average of ≤ 6.9 hours, they were instructed that they would lose points (no points were actually deducted). Of the 28 students enrolled in the course, 22 students attempted the challenge (78.6%), and we monitored their sleep duration objectively using wristband actigraphy devices. We compared their sleep duration to that of a group of 22 non-incentivized students enrolled in the same program. In the non-incentivized comparison group, very few students averaged 8 hours (9%) or even 7 hours (14%) of sleep per night. In dramatic contrast, the eight-hour challenge increased the percentage of 8-hour and 7-hour sleepers to 59% and 86%, respectively. Participants who took the eight-hour challenge slept an average of 98 minutes more each night than non-incentivized students and 82 minutes more than they self-reported to sleeping during the semester. The substantial increase in nightly sleep duration did not come at a cost to project performance. Individuals who opted in to the sleep challenge performed as well on the final project as students who did not opt in, and students who showed more consistent sleep (i.e., fewer nights of poor sleep followed by rebound sleep) performed better than students who showed inconsistent sleep. Thus, even during highly stressful "deadline" weeks, students can maintain healthy sleeping patterns without exacting a cost on their project performance.

8小时挑战：期末评估期间激励睡眠。

睡眠对身体健康，心理健康，注意力和创造力至关重要。但是，在期末考试的一周内，只有不到10％的本科生维持建议的平均8个小时/晚（甚至建议的最少7个小时/晚）。对于在工作室专业（例如，室内设计，建筑，图形设计，工作室艺术）中完成多方面项目的学生而言，轶事和问卷数据表明，学期末睡眠时间的减少可能更加糟糕。一种潜在的解决方案是激励学生保持健康的睡眠时间。我们为入读新生级图形工作室课程的室内设计学生提供了一项可选的额外学分奖励措施，以在其最终项目的截止日期之前的五个晚上保持最佳睡眠时间。如果参与者连续五个晚上的平均睡眠时间≥8.0小时，他们将获得额外的积分。相比之下，如果他们平均睡7.0-7.9小时，则不会有成绩变化；如果他们平均睡≤6.9小时，他们将被指示失去分数（实际上未扣除任何分数）。在参加该课程的28名学生中，有22名学生尝试了挑战（78.6％），我们使用腕带书法设备客观地监测了他们的睡眠时间。我们将他们的睡眠时间与参加同一计划的22名非激励学生的睡眠时间进行了比较。在非激励比较组中，很少有学生每晚平均睡眠8小时（9％），甚至7小时（14％）。形成鲜明对比 8个小时的挑战将8个小时和7个小时的卧铺比例分别提高到59％和86％。参加八小时挑战赛的参与者每晚的睡眠时间比未受激励的学生平均多睡98分钟，比他们本学期报告的睡觉时间多睡82分钟。夜间睡眠时间的大量增加并不以牺牲项目绩效为代价。选择参加睡眠挑战的个人在未参加最终项目的学生中表现也不错，而表现出较稳定的睡眠（即睡眠差的夜晚较少，然后出现反弹性睡眠）的学生比表现出不一致的学生表现更好睡觉。因此，即使在压力很大的“最后期限”周中，
