The Importance of a Good Night’s Sleep

You may not realize the benefits of sleep, or the problems associated with being sleep deprived, because most likely you’ve had the same sleep habits for a long time. Or maybe you know you’re getting less sleep now, but with all the changes in your life, how can you tell if some of your stress or problems studying are related to not enough sleep?

On the positive side, a healthy amount of sleep has the following benefits:

• Improves your mood during the day
• Improves your memory and learning abilities

How Much Sleep Is Enough?

College students are the most sleep-deprived population group in the country. With so much to do, who has time for sleep?

Most people need seven to nine hours of sleep a night, and the average is around eight. Some say they need much less than that, but often their behavior during the day shows they are actually sleep deprived. Some genuinely need only about six hours a night. New research indicates there may be a “sleep gene” that determines how much sleep a person needs. So how much sleep do you actually need?

There is no simple answer, in part because the quality of sleep is just as important as the number of hours a person sleeps. Sleeping fitfully for nine hours and waking during the night is usually worse than seven or eight hours of good sleep, so you can’t simply count the hours. Do you usually feel rested and alert all day long? Do you rise from bed easily in the morning without struggling with the alarm clock? Do you have no trouble paying attention to your instructors and never feel sleepy in a lecture class? Are you not continually driven to drink more coffee or caffeine-heavy “power drinks” to stay attentive? Are you able to get through work without feeling exhausted? If you answered yes to all of these, you likely are in that 10 percent to 15 percent of college students who consistently get enough sleep.

How to Get More and Better Sleep

You have to allow yourself enough time for a good night’s sleep. Using the time management strategies discussed in Chapter 2 "Staying Motivated, Organized, and On Track", schedule at least eight hours for sleeping every night. If you still don’t feel alert and energetic during the day, try increasing this to nine hours. Keep a sleep journal, and within a couple weeks you’ll know how much sleep you need and will be on the road to making new habits to ensure you get it.

If you can’t fall asleep after ten to fifteen minutes in bed, it’s better to get up and do something else rather than lie there fitfully for hours. Do something you find restful (or boring). Read, or listen to a recorded book. Go back to bed when you’re sleepy.
