But it's not just a matter of choice -their bodies are going through a change of sleep patterns. All of this makes the transfer from middle school to high school--which may start one hour earlier in the morning ---- all the more difficult , Carskadon says. With their increased need for sleep and their biological clocks set on the "sleep late, rise late" pattern, adolescent are up against difficulties when it comes to trying to be up by 5 or 6 a.m. for a 7:30 a.m. first bell. A short sleep on a desktop may be their body's way of saying. "I need a timeout." Question: What is the test mainly about? - Adolescent heath care. - Problems in adolescent learning. - Adolescent sleep difficulties. - Changes in adolescent sleep needs and patterns.
