Final answer:
College students often do not get adequate sleep due to stress and overwhelming schedules. Sleep debt affects alertness and mental efficiency. Healthy sleep habits involve stress management and a conducive sleep environment.
Step-by-step explanation:
Kimberly's research on college students and sleeping is likely to have found that a significant percentage of students did not get adequate sleep. Many college students struggle with getting the recommended 7-9 hours of sleep each night. Factors contributing to this can be stress, overwhelming academic schedules, and sleep disorders such as insomnia. The National Sleep Foundation updated their sleep duration recommendations to accommodate individual differences, and while the exact percentage from Kimberly's survey isn't provided in the question, existing research suggests that a considerable number of students experience sleep debt. Insufficient Sleep can lead to decreased alertness and mental efficiency. To support healthy sleep habits, it is essential to manage stress and create a conducive sleep environment.
