Levels of Sleep
What does REM stand for?
Rapid Eye Movement
What is neural firing?
Neural firing, or nerve impulse, is when neurons communicate with each other and move information throughout the body through the nervous system.
What is sleep deprivation?
Being super tired because you haven't gotten enough sleep. Typically, this would happen over a long period of time.
How would you define sleep hygiene?
The habits you have that promote good sleep.
Why is REM important?
It's the deepest stage of sleep when you're body can truly rest and recharge.
What does neural firing have to do with sleep?
The more rested you are, the faster your neurons can love through your body and transport information == the faster you can recall information on a test, recall your lines for the play, or react to an opponent on the field.
How does sleep deprivation affect you physically?
Being tired slows down your reaction time, which can subject you to injury and/or sadness associated with game losses.
Name an example of good hygiene.
Going to sleep at the same time each night.
How many hours do you have to be asleep before your brain can relax into REM?
Usually in the 3rd hour of sleep, your brain will begin to let the delta waves take over and you enter REM sleep.
How does sleep affect your long term memory?
Getting enough sleep essential for transferring short-term memories into long-term storage. Your rested brain can process and organizes information learned that day, making it more likely to be remembered.
How does sleep deprivation affect you mentally?

3-6, but it depends on how long you are asleep.
They only last a few (5-10) minutes, but each one is longer than the last. That's why allowing your brain enough hours of asleep is important for full REM recovery.
Why is sleep vital to the adolescent brain?
Significant brain maturation takes place during adolescence. Structural and functional changes are happening that play a critical role in one's ability to control behavior, cognition, and emotions.

What does the following phrase mean, and how does sleep play a role-
Neurons that fire together, wire together.
Repeated neural activity strengthens the connections within your nervous system, allowing you to learn better, remember better, and perform better.
During deep (good quality) sleep, when your body is able to truly shut down the engine, your cognitive battery recharges. Your brain and body are better at all the things after good sleep!
How does sleep deprivation affect your immune system?
When your body isn't allowed time to rest and recharge, your immune system becomes weak and less capable of fighting off illnesses.
One last example of sleep hygiene.
Getting enough sleep, between 7-9 hours, so that your body slips easily into the rest pattern you've created.
