Teenagers and Sleep

Parent Question: What are the sleep needs of high school age teens? How much is enough?

Teens need from 8 1/2 and 9 1/4 hours of sleep each night. Most adolescents DO NOT get enough sleep – one report found that only 15% reported sleeping 8 1/2 hours on school nights.

What are the side effects of lack of sleep?

Teens tend to have irregular sleep patterns across the week – they typically stay up late and sleep in late on weekends. This irregularity affects their biological clocks and hurts the quality of their sleep. Some side effects include: Limits ability to learn, listen, concentrate and solve problems; Contributes to acne and other skin problems; Leads to inappropriate or aggressive behavior (e.g. yelling, impatience with family members and teachers); Eat unhealthy foods (e.g. sweets, fried foods) that lead to weight gain; Performs poorly in sports (e.g. reduced endurance and cardiovascular performance, delayed visual and auditory reaction time).

How do school schedules conspire against them getting enough sleep?

Schools ask teens to sleep at the wrong times. A teen’s biological clock is in conflict with the school bell. Too many teens come to high school too sleepy to learn. A few schools have become “sleep-smart” by setting later bell times. They’ve found that students do not go to bed later, but get one hour more of sleep per school night, which means five hours more per week. Parents and teachers contend that starting school later improves student morale and attitudes. Students report that they feel ready to learn when they get to school in the morning.

What are some pointers for parents?

1. Be a good role model. Practice good sleep hygiene yourself.
2. Enforce regular sleep schedules for all children and teens. Establish a quiet relaxing time in the evening before bedtime when music and television are not permitted.
3. Talk with your kids about their sleep/wake schedules. Assess time in extracurricular activities and outsides jobs, and make adjustments, if appropriate.
4. Consider having each teen keep a sleep diary for 1 or 2 weeks. Review it for poor sleep hygiene, and make an effort to change patterns, if necessary.
5. During vacations, help your teen adjust for a smooth transition to the upcoming school schedule. Go to sleep and awaken 15 minutes earlier each day until teen reaches desired sleep and wake times.
6. Always be on the look out for signs of sleep deprivation—difficulty waking in the morning, falling asleep during quiet times in the day, irritability in late day, and sleeping super-long on weekends.
7. Avoid use of caffeine and other substances that can affect sleep.
