Snooze You Can Use—
Sleep Quiz Answers

1. False is correct. Although it is a time when your body rests and restores its energy levels, sleep is an active state that affects both your physical and mental well being.

2. True is correct. Many people doze off unintentionally during the day despite getting their usual night of sleep. This could be a sign of a sleep disorder.

3. True is correct. Persistent loud snoring at night and daytime sleepiness are the main symptoms of a common and serious sleep disorder, sleep apnea. Another symptom is frequent long pauses in breathing during sleep, followed by choking and gasping for breath.

4. False is correct. Opening the car window or turning the radio up may arouse a drowsy driver briefly, but this won't keep that person alert behind the wheel. Even mild drowsiness is enough to reduce concentration and reaction time. The sleep-deprived driver may nod off for a couple of seconds at a time without even knowing it—enough time to kill himself or someone else.

5. True is correct. People with narcolepsy fall asleep uncontrollably—at any time of the day, in all types of situations—regardless of the amount or quality of sleep they've had the night before. Narcolepsy is characterized by these 'sleep attacks,' as well as by daytime sleepiness, episodes of muscle weakness or paralysis, and disrupted nighttime sleep.

6. False is correct. Insomnia has many different causes, including physical and mental conditions and stress. Insomnia is the perception that you don't get enough sleep because you can't fall asleep or stay asleep or get back to sleep once you've awakened during the night. It affects people of all ages, usually for just an occasional night or two, but sometimes for weeks, months, or even years.

7. True is correct. Restless legs syndrome (RLS) is a medical condition distinguished by tingling sensations in the legs—and sometimes the arms—while sitting or lying still, especially at bedtime. The person with RLS needs to constantly stretch or move the legs to try to relieve these uncomfortable or painful symptoms. As a result, he or she has difficulty falling asleep or staying asleep and usually feels extremely sleepy and unable to function fully during the day. Good sleep habits and medication can help the person with RLS.

8. False is correct. The human body's biological clock programs each person to feel sleepy during the nighttime hours and to be active during the daylight hours. So people who work the night shift and try to sleep during the day are constantly fighting their biological clocks. This puts them at risk of error and accident at work and of disturbed sleep. Sleeping during the day in a dark, quiet bedroom and getting exposure to sufficient bright light at the right time can help improve daytime alertness.

9. False is correct. As we get older, we don't need less sleep, but we often get less sleep. That's because our ability to sleep for long periods of time and to get into the deep restful stages of sleep decreases with age. Older people have more fragile sleep and are more easily disturbed by light, noise, and pain. They also may have medical conditions that contribute to sleep problems. Going to bed at the same time every night and getting up at the same time every morning, getting exposure to natural outdoor light during the day, and sleeping in a cool, dark, quiet place at night may help.

10. True is the correct answer. Our bodies are programmed by our biological clock to experience two natural periods of sleepiness during the 24-hour day, regardless of the amount of sleep we've had in the previous 24 hours. The primary period is between about midnight and 7:00 a.m. A second period of less intense sleepiness is in the midafternoon, between about 1:00 and 3:00. This means that we are more at risk of falling asleep at the wheel at these times than in the evening--especially if we haven't been getting enough sleep.
