By: Savannah Gomes

2. What Is Sleep?
Sleep is a natural occurrence when your consciousness is suspended.
Humans sleep for about one third of their entire life.
A 75 year old will have probably slept for 25 years if all hours spent sleeping are added together.

3. Why Do We Need Sleep?
Nobody is sure WHY we sleep.
There are different theories concerning why we sleep. These are two of those theories:
It is a Restorative Process: it helps he body recover.
It is an Adaptive Process: instead of walking around blindly during the night, animals, such as humans, save energy for when the sun comes up again.

4. REM Sleep
During REM sleep, the eyes move rapidly in different directions.
Humans enter REM sleep every night.
Dreams usually happen during REM sleep.
Periods of REM occur about every 90 minutes.
The first stage of REM sleep may last for only 10 minutes. The final stage of REM sleep may last for up to an hour.
Infants spend more time in REM sleep than adolescents do.
REM sleep is sometimes referred to as Paradoxical Sleep.

5. NREM Sleep You begin sleeping in the NREM state. NREM has 4 stages.
Stage 1: During this stage, being awoken easily by a touch or sound is common. Activity is reduced between wakefulness and this stage—stage 1.
Stage 2: During this stage, heart rate slows and body temperature lowers. The body is preparing for deep sleep.
Stage 3/4: These are called deep sleep stages.
Each stage can last anywhere from 5 to 15 minutes.

6. Dreams
Because most dreaming happens during REM sleep, when a person is awakened directly from it, they can usually remember the dream.
While dreaming, a person usually speaks with grammatically correct English.
Most dreams occurring during REM are:
Not related to the current life of the person dreaming
Lengthy
Primarily visual
Emotional
Most dreams occurring during NREM are:
Related to the current life of the person dreaming
Short
Primarily thoughtful
Not very emotional

7. Teenager’s Sleep: Facts
Teenagers’ sleep patterns are irregular across the week. They wake up late on weekends, but early on weekdays.
Many teens may suffer from treatable sleep disorders such as:
Narcolepsy: A person with this disorder may fall asleep at inappropriate times.
Insomnia: Sleeplessness.
Sleep Apnea: Breathing disorder.
Restless Leg Syndrome: tingling or numbness in the legs.
Sleep disorders affect as many as 70 million people in the US alone.
During the week teens wake up early, go to sleep late, during the weekend teens wake up late, might not sleep.

8. What Affects Teenagers’ Sleep?
An adolescence's biology may be
affecting their sleep.
A chemical that makes humans tired is released later in an adolescent than in a child or adult.
For example, if a teenager is not able to fall asleep before midnight, it is a normal change.
Sleep disorders may also be a cause for limited sleep.

9. How Does Not Enough Sleep Affect Daily Life?
Limits your ability to learn
Can cause too much eating(especially junk food)
Can lead to violent acts
Mood swings
Driving sleep deprived is dangerous for yourself and others
Impairs memory
This could happen because the brain is not working properly—according to the Restorative Process Theory.
This could happen because the body has used up all of the energy it conserved—according to the Adaptive Process Theory.

10. Not Tired Yet?
Do not exercise or eat within a few hours of going to bed. It makes you heart rate go up.
Keep your bedroom quiet, dark, and cool at night.
Do not watch TV right before going to bed.
Listen to peaceful music before going to bed.
Make sure the naps aren’t too close to “bedtime” and aren't too long.

11. Conclusions Sleep is important.
If you do not get enough sleep at night, you are more likely to fall asleep during the day.
Not enough sleep can lead to unhealthy eating habits and unhealthy social habits.
To fall asleep more easily, make your bedroom quiet, cool, and dark at night or listen to relaxing music.
The different stages of sleep present different occurrences and different types of dreams.
