About Sleep

Found this online... nice piece of information... you guys might find the last part interesting.

Everyone needs different amounts of sleep, but the general consensus is that adults require between six and eight hours of sleep per night [source: APA]. Nobody passed this information along to Leonardo da Vinci. He practiced something called polyphasic sleep -- taking 20- to 30-minute naps every few hours throughout the day and night. Some people are big on "Da Vinci sleep," but it's not generally endorsed by mainstream science.

The amount of sleep you need also changes as you age. Newborn babies have it made -- they sleep 16 to 18 hours every day. So if you're sleeping like a baby, you probably aren't getting much done. At the three-month mark, babies start to recognize day as day and night as night. This is called the circadian rhythm. By the time they hit one year, most of which is spent sleeping, babies slumber for 10 to 12 hours each night and nap another three to five hours. Pretty nice lifestyle. By preschool, those long naps aren't happening.

Once kids hit puberty, they'll need more sleep than in their prepubescent period. Their body clocks shift, making it tougher to fall asleep and harder to wake up in the morning. In fact, teenagers don't start producing their sleep hormones until 1 a.m., compared to 10 p.m. in adults [source: The New York Times]. So lay off, Mom and Dad -- the teenager who won't go to sleep and can't wake up is really pretty normal. Researchers performed tests on teenagers and found that taking away just one hour of sleep led to poorer test scores, reaction time, recall and responsiveness.
