Researchers observing sleep patterns find that approximately 20% of college students suffer from a sleep disorder. The hours spent attending class, working, and studying can strain a college student's ability to get adequate sleep. Unfortunately, the methods used to combat lack of sleep may make the problem worse. Which of the following statements exemplifies this situation? Check all that apply. Napping for approximately 20 minutes at least 3 hours before bedtime will increase productivity and reduce mental fatigue. Alcohol consumption can increase the number of times you wake up at night and reduce the amount of time spent in critical stages of sleep. Exercising at least 3 hours before bedtime will make it easier to fall asleep and gain quality sleep. Ensuring you get at least 8 hours of sleep a couple nights a week will help prevent long-term health issues.
