It is 7 am and the alarm is going off. You know you have to be out of bed to catch the bus. But the urge to bury yourself in the bed is ever so strong.
Sounds familiar? Why is it that teens find it difficult to get themselves out of bed in time every morning or stay sharp and focused during the first couple of hours of school?
During adolescence, the body goes through many changes and these include a shift in sleep patterns. Researchers from MIT have been tracking the body's need for sleep in teenagers. They found that though adolescents need as much as 9.5 hours of sleep a day, they get to bed later and later with each passing year. In fact, the sleep cycle shifts later by as much as 12 to 18 minutes each year between the ages of 10 and 20! So by the time a 10yearold who sleeps at 8 pm grows to be 17 or 18, his body naturally wants to stay up till 10:30 pm or 11 pm.
According to researchers, this is because of a hormone called melatonin (褪黑激素) that is secreted (分泌) by the pineal gland — a tiny structure deep inside the brain. Melatonin regulates the body's natural daynight rhythms. It causes a person to become sleepy by lowering his body's core temperature. In teens, melatonin is secreted much later in the evening and continues to increase throughout the night. This makes it difficult for teens to fall asleep earlier as they did in their younger years. Likewise, the effect of melatonin continues until much later in the morning, making it hard for them to wake up early.
A study found that at least one in four teens is tired and falls asleep in school at least once a week. During sleep, important body functions and brain activities happen. So how can teenagers get their sleep enough? The American Academy of Pediatrics (AAP) recommends that middle and high schools should start later — not before 8:30 am. This should give teens some more time to sleep at night.
