Everything that's alive needs sleep to survive. Even your dog or cat curls up for naps. Animals sleep for the same reason you do - to give your body a tiny vacation.
Not only is sleep necessary for your body, it's important for your brain, too. Though no one is exactly sure what work the brain does when you're asleep, some scientists think that the brain sorts through and stores information, replaces chemicals, and solves problems while you snooze.
When your body doesn't have enough hours to rest, you may feel tired or cranky, or you may be unable to think clearly. You might have a hard time following directions, or you might have an argument with a friend over something really stupid. A school assignment that's normally easy may feel impossible, or you may feel clumsy playing your favorite sport or instrument.
One more reason to get enough sleep: If you don't, you may not grow as well. That's right, researchers believe too little sleep can affect growth and your immune system - which keeps you from getting sick.
The Stages of Sleep
As you're drifting off to sleep, it doesn't seem like much is happening . . . the room is getting fuzzy and your eyelids feel heavier and heavier. But what happens next? A lot!
Your brain swings into action, telling your body how to sleep. As you slowly fall asleep, you begin to enter the five different stages of sleep:
Stage 1
In this stage, your brain gives the signal to your muscles to relax. It also tells your heart to beat a little slower, and your body temperature drops a bit.
Stage 2
After a little while, you enter stage 2, which is a light sleep. You can still be woken up easily during this stage. For example, if your sister pokes you or you hear a car horn outside, you'll probably wake up.
Stage 3
When you're in this stage, you're in a deeper sleep, also called slow-wave sleep. Your brain sends a message to your blood pressure to get lower. Your body isn't sensitive to the temperature of the air around you, which means that you won't notice if it's a little hot or cold in your room. It's much harder to be awakened when you're in this stage, but some people may sleepwalk or talk in their sleep at this point.
Stage 4
This is the deepest sleep yet and is also considered slow-wave sleep. It's very hard to wake up from this stage of sleep, and if you do wake up, you're sure to be out of it and confused for at least a few minutes. Like they do in stage 3, some people may sleepwalk or talk in their sleep when going from stage 4 to a lighter stage of sleep.
REM
This stands for Rapid Eye Movement. Even though the muscles in the rest of your body are totally relaxed, your eyes move back and forth very quickly beneath your eyelids. The REM stage is when your heart beats faster and your breathing is less regular. This is also the stage when people dream!
While you're asleep, you repeat stages 2, 3, 4, and REM about every 90 minutes until you wake up in the morning. For most kids, that's about four or five times a night. Who said sleep was boring?
Dream a Little Dream
You're walking down the street and you pass a monkey in a green hat eating a donut. Suddenly you're in school - but why does your teacher have such big teeth? And how come you're wearing polka-dot pants?
No, this isn't a scene from a scary movie - it's a dream!
People dream during REM sleep, the period that follows the deepest stage of sleep. Everybody has dreams, although some people have a tough time remembering them. When you wake up can affect whether you can remember your dreams. If you wake up during REM sleep, you might remember everything about your dream. If you wake up during another stage of sleep, you might not remember a thing.
No one knows for sure why people dream. Some scientists think that dreams are your brain's way of making sense of what happened during the day. Others think that dreams allow your brain to sort through the events of the day, storing the important stuff and getting rid of the junk. Some scientists say that dreams are a clue to what you're worried about or thinking about.

Going to bed each day allows us the opportunity to awake in the morning and thank God for each day that he grants us.

Because we can and if we did not we would fall asleep in some odd places and that would be a giggle but not in the middle of the road.
