Transcript of Sleep

Why do teenagers stay up late and wake up late?
Circadian Clock
The circadian clock (body clock), is controlled by the hypothalamus. In children and adolescents, hormones that promote growth are released during sleep.
If you are finding it hard to fall asleep, try out these tips.
Perform Poorly
Teenagers that don't get enough sleep perform poorly.
They won't do the best they can with school exams. They might even fall asleep during it!
Let's Find Out!
Melatonin is produced by various tissues in the body, although the major source is the pineal gland in the brain. It is released when the circadian clock sends signals to parts of the brain including the pineal gland. Melatonin makes you feel drowsy and sleepy. Melatonin is released when its dark.

What happens to teenagers if they don't get enough sleep?
Teenagers who do not sleep well all the time, may fall asleep at inappropriate times.

Emotional state
Teenagers get moody when they don't get enough sleep. They don't get along with other people and can get mood swings.
What is the brain doing when you sleep?
Tip #1
You shouldn't play on digital devices
before you sleep because it produces
light and stops melatonin being released.
The US Nationwide Children's Hospital says, that the average amount of sleep teenagers get is between 7 and 7 1/4 hours. They need between 9 and 9 1/4 hours.
How Much Sleep Are Teens Getting?
Tip #2
Instead of watching television before bed you could read a book.
Tip #3
You shouldn't have too much caffeine before bed. When we drink coffee, caffeine binds to our brain's adenosine receptors, preventing the chemical from binding with the receptors and making us tired.
Stick to the same sleeping schedule at night so your body can get used to it.
Tip #5
Ensure a good sleep environment such as a dark room.
Tip #4
Tip #6
Do not spend more than three hours on a computer or you will not sleep properly.

The Owners Manual for Driving Your Adolescent Brain By JoAnn Deak, Ph.D and Terrence Deak, Ph.D
Changes to this circadian rhythm occur during adolescence, when most teens experience a sleep phase delay. This shift in teens circadian rhythm causes them to naturally feel alert later at night, making it difficult for them to fall asleep before 11:00 pm. Since most teens have early school start times along with other commitments, this sleep phase delay can make it difficult to get the sleep teens need an average of 9 1/4 hours, but at least 8 hours of sleep.
