The sleep-wake bio-regulatory factors appear to undergo significant changes during adolescence. These changes lay the ground work for the biological night to occur later during the teen years than before. The circadian timing system (daily biological clock) seems to slow down and lag behind as young people progress through the middle school years. At the same time, the sleep pressure system appears to change in a way that makes it easier to stay awake longer, though without changing the amount of sleep that is needed.
It is no longer an issue of electric lights in the home, but many teens have a veritable technological playground in their bedrooms: television, computer with 24/7 Internet access, telephones, electronic game stations, MP3 players, and so forth. These technologies can also provide instant and incessant contact with peers. Societal/media pressure to consume these technologies is now higher than ever. Yet society also requires that teens go to school at a time of day that is at odds with their biological and social lives. It’s more surprising to find teens in the U.S. today that get enough sleep than those who get too little.
These patterns can disguise the extent of their sleep deficit for many teens and their parents as well. On the other hand, we do see the signs emerge in many young people, each may be vulnerable in different ways. Thus, we see the teenager who falls asleep driving home late at night; in another teen, the problem emerges with titanic struggles to wake up in the morning, often failing and resulting in late or missed school; another may simply feel sad and moody and blue, lacking initiative or motivation; in other teens, grades begin to suffer as the teen struggles to keep awake during class and while doing homework; another may turn to heavier drugs to get some positive and arousing sensations; many just struggle along in a kind of haze, never knowing how to feel or do their best.
