Essentially, the adolescent inability to be fully awake before then is a matter of human biology – not a matter of attitude.
In the earliest days of American education, students of all ages attended a single school with a single starting time.
This fixed pattern of melatonin secretion in teens changes back to an individual’s genetically preferred sleep/wake timing once puberty is over.
The unique sleep/wake pattern of teens is beyond their control.
Researchers around the world corroborated these findings.
In preteens and adults, the secretion of melatonin is flexible and variable, and sleep timing preferences are genetically based.
As they struggle to get up early, parents battle to get them out of bed and off to school – a stressful way for everyone involved to start the day.
Are teenagers just being lazy when they have to be dragged out of bed in the morning?
But the timing is different in teens, as it is related to puberty.
For virtually all adolescents, the secretion of melatonin doesn’t begin until about p.m. This means that most teenagers are unable to fall asleep until melatonin secretion begins, and it’s hard to wake up until the melatonin secretion stops.
