The document discusses the results of a sleep log completed by a high school psychology class over 35 days. It found that most students slept less than the recommended 9.5 hours per night and accumulated around 50 hours of sleep debt over the month. On average, students slept 7.35 hours per night and took naps accounting for 63 hours of additional sleep. However, this still fell short of the recommended hours of sleep for their age. Not getting enough sleep can negatively impact mood, focus, health and school performance.
