According to a recent University of Colorado School of Medicine study, too many sleepless nights can affect teenagers' grades. A study of 238 middle school and high school students revealed that those with consistently lower grade point averages suffered more from daytime sleepiness, snoring, difficulty concentrating, and difficulty waking up than their peers with higher GPAs. The study offered several tips for sleeping better, including the following:
1) Don't stay up late cramming for tests or doing homework.
2) Go to sleep at a regular time each evening, and set your alarm for waking up at a regular time.
3) If you can't sleep within 20 minutes of hitting the sack, get up and read or listen to music until you're tired.
4) Avoid after-school naps.
5) Don't consume caffeine after lunch.
6) Make sure your bedroom is quiet and dark; light and noise can keep you awake.
7) Don't eat a large meal right before bedtime.
8) Don't exercise vigorously within six hours of bedtime.
