  3. Answers

  4. 1. During sleep, your brain rests. False. Although the body rests, the brain remains very active. The brain repairs & reorganizes itself, and consolidates memories. This prepares us for peak functioning the next day.

  5. 2. You can not learn to function normally with one or two hours less sleep than you require. True. Sleep need seems to be biological. You can not simply learn to require less sleep.

  6. 3. Boredom makes you feel sleepy, even if you’ve had enough sleep. False. Boredom, like a dark room, or a warm room, does not ‘cause’ sleepiness. It may, however, unmask sleepiness that is already there, causing you to notice you are sleepy.

  7. 4. Resting in bed with your eyes closed can not satisfy your body’s need for sleep. True. Sleeping is much more than just laying still with your eyes closed. Sleep is an active process. True sleep is as necessary to good health as food and water.

  8. 5. Snoring is not harmful, as long as it doesn’t disturb others or wake you up. False. Snoring may signal the presence of sleep apnea.

  9. 6. Everyone dreams every night. True. Humans dream every time they sleep, under normal circumstances. We most often forget our dreams.

  10. 7. The older you get, the fewer hours of sleep you need. False. Sleep needs remain unchanged throughout adulthood.

  11. 8. Most people don’t know when they are sleepy. True. Research shows that people are very poor at judging whether or not they are tired.

  12. 9. Raising the volume on your radio will help you stay awake while driving. False. The only short term solution to sleepiness while driving is pulling over to take a nap, or drinking a caffeinated drink.

  13. 10. Sleep disorders are mainly due to worry, or psychological problems. False. Chronic sleep disorders have diverse causes.

  14. 11. The human body never adjusts to night shift work. True. Humans can never fully adjust to working night shift. Our brain works on a 24-hour circadian rhythm, based on sunlight.

  15. 12. Most sleep disorders go away without medical treatment. False. Sleep disorders do not disappear without treatment.

  16. DISCUSSION QUESTIONS: • Roughly how many hours of sleep do you get a night? • How would you describe your sleeping habits? • Why do you think today’s teenagers don’t get enough sleep? • At what time of the day do you feel most awake/most tired? Do you structure your day accordingly? How? Why?
