Many teenagers have the energy to play computer games 

until late at night but can’t fi nd the energy to get out of bed in time 

for school. Is it just laziness or is it something more? New 

research suggests that the reason for such behaviour may be the hormonal changes of puberty. It could be the hormones that stop teenagers from going to bed early and make them sleepy in the morning. One thing is for certain - sleep is extremely important for teenagers because it is while they are sleeping that they release a hormone that is essential for their growth. They need more sleep than both 

children and adults. At night our body produces the ‘darkness hormone’ melatonin 

which helps us to fall asleep.

Most adults start to produce melatonin at about 10 pm. Research has shown that teenagers start to produce the hormone at 1 am. In other words, teenagers are being kept awake by their bodies and there is not much they can do about it. 

The fact that they play computer games and watch television late at night stimulates the brain even more and makes it harder for them to fall asleep.

Whatever the reason, most teenagers do not get enough sleep. This results in bad moods and sometimes depression. In America, some schools have decided to start their classes later in the morning to give their teenagers some extra time in bed. 

They noticed their students did much better in class when they did not have to get up early.

Why is sleep important for teenagers?
