Your teen can take advantage of this by turning on bright lights first thing in the morning and by dimming the lights in the evening. Take a critical look at your teen's schedule of extracurricular activities and employment. It may be necessary to make some adjustments to ensure that your teen has adequate time for sleep. It's OK for teens to nap right after school or on a weekend afternoon. Napping in the evening isn't a good idea, though.
Late naps can interfere with nighttime sleep.
Remind your teen to be careful about caffeine. To avoid disrupting sleep, it's best to avoid coffee and caffeinated sodas after lunch. Never let your teen or any other family member drive when sleep deprived or drowsy. Driving drowsy is as dangerous as driving drunk. If the high school bell in your community rings too early, you and other parents may want to ask your Board of Education to consider the possibility of modifying the school schedule.
