It's a time when school, homework, community service, extracurricular activities, active social lives and part-time jobs keep them busy from early in the morning until late at night. They are likely to try to make up for a lack of sleep by 'sleeping in' on the weekends. Unfortunately, this contributes to an irregular sleep schedule and actually makes the problem worse, setting them up for a kind of jet lag when Monday morning rolls around.
In addition to having a difficult time turning off the worries of their day, most teens show signs of delayed circadian rhythms -- which contributes to their inability to fall asleep until later at night. Since many teens aren't sleepy until around 11 PM, but need to be at school by 7:30 or 8 a.m., they cannot get an adequate amount of sleep. During puberty, the biological clock in the brain naturally resets to a later time. The pineal gland releases melatonin later at night and this causes teens to fall asleep later. Then, when it's time to get up, a teenager's body clock is likely to still be producing the nighttime hormones. This makes it hard for them to feel active and energetic in the morning.
A growing body of research suggests that starting high school later, more in line with their natural biorhythms, improves attendance, tardiness, achievement and grades. A few years ago in a landmark study, test scores on the SAT college entrance exams in Edina, Minnesota jumped more than 100 points on average, when the morning school bell was delayed for an hour. Unfortunately, most schools are not set up to start later and accommodate teen's sleep needs.
Lack of sleep can be very dangerous for young drivers and it's vitally important to warn teenagers about the dangers of driving while drowsy. Although parents always warn their teens about the dangers of drinking and driving, many of us forget to warn our teens not to drive when they're drowsy, a very real danger today. Drowsiness is the principal factor in about 100,000 car crashes each year, killing adults, teens and children.
If you feel your teenager has a serious problem falling asleep at night and simply can't get going in the morning, check with your physician. If you choose to consult with a naturopath, he or she may prescribe melatonin supplements and/or light therapy.
