Sleep Cycle Part of the cycle of sleep and
waking. Circadian Rhythm: naturally
occurring 24-hr cycle. Rest-activity of actually 25.1
hours.Stay up longer, sleep in less.
Electrical activity in the brainHigher-frequency when awakeLower-frequency when relaxed
Sleep Stages Stage 1: Drifting into sleep.
“Trying” to sleep. Stage 2: Light Sleep. Lose
awareness. Stage 3: Starting to fall into
Deep Sleep. Stage 4: Deep Sleep. REM Stage: Rapid Eye
Movement. Dreaming.
EEG Patterns Electroencephalograph
(Measures electrical impulses produced by the brain’s activity)
Sleep Needs Varies depending on the age
group. Sleep helps with learning. Sleep Deprivation.

Sleeping DisordersBy Aubrey Dedrickson
Insomnia Difficulty falling asleep or
staying asleep
15% of adults complain of severe insomnia 15% report mild or occasional insomnia Causes for insomnia include: anxiety, stress,
emotional difficulties Some things to help with insomnia are better
sleep habits, using relaxation techniques One solution to help insomnia is give up the
pursuit of sleep and find something to do Sedatives such as sleeping pills can be helpful
but they can be addicting and people become dependent on them
Sleeping pills can also interfere with your normal sleep cycle and have side effects such as grogginess and irritability
Sleep Apnea Disorder in which the person stops
breathing for brief periods while asleep
Person with apnea usually snores, as apnea involves an involuntary obstruction of the breathing passage
When apnea occurs over 10 seconds at a time a person may awaken and have sleep loss or insomnia
Sleep apnea most often occurs in middle-aged men who are overweight
Sleep apnea can go undiagnosed because it is not easy for a sleeper to notice
To detect sleep apnea usually the sleeper’s bed partner will get tired of the snoring and awaken the sleeper
Some cures for sleep apnea are weight loss, drugs, or surgery
Somnambulism When a person arises and walks
around while sleeping, also known as sleepwalking
Sleepwalking is more common in children around the ages of 11 or 12, with as many as 25% experiencing at least one episode
Sleepwalking tends to happen early in the night, usually in slow-wave sleep. Sleepwalkers may awaken during their walk or return to bed without waking, in which case they won’t remember anything in the morning
Sleepwalkers can hurt themselves by tripping over furniture or falling down the stairs
Contrary to popular belief it is safe to wake sleepwalkers or lead them back to bed
Narcolepsy Disorder in which sudden sleep
attacks occur in the middle of waking activities
Narcolepsy involves the intrusion of a dreaming state of sleep (REM) into waking and it often accompanied by excessive sleepiness and incontrollable sleep attacks lasting from 30 seconds to 30 minutes
Narcolepsy is a less common sleep disorder
The disorder appears to have a genetic basis, as it runs in families
Narcolepsy can be treated with medication
Sleep Paralysis The experience of waking up
unable to move or speak for a few minutes
This eerie feeling only lasts for a few moments and may occur with an experience of pressure on the chest
Is sometimes associated with narcolepsy
Night Terrors Abrupt awakenings with panic
and intense emotional arousal
Mostly occurs with boys ages 3 to 7 Night terrors usually doesn’t have
dream content the sleeper can report Night terrors usually occur within the
first few hours of sleep, whereas nightmares occur towards the end of the night or early morning hours
Night terrors occur during non-REM sleep and nightmares occur during the REM of sleep
Test Question What is the sleep disorder in
which sudden sleep attacks occur in the middle of wakening activities?
DreamsBy Celeste Madsen
The Mind dreams are a result of activities
taking place in the brain. Scientist have found that the brain
gives off electromagnetic waves while you dream.
During the period while the electromagnetic waves are fast your eyes are moving rapidly
Sometimes while dreaming you cannot move your body, this period is called REM
Mind Scientist believe that dreaming
sleep has a role in restoring the brain's ability to handle such tasks as focused attention, memory, and learning. Also a person's hidden feelings often surface in dreams
Brain Waves:
Tips to avoid nightmares and to get a good nights sleep:
Sleep schedule Avoid caffeine Exercise Don’t lie awake in bed Control temperature
what you can do? Before you go to bed: write down the
date and what events happened that day (journal)
If you wake up in the middle of the night: try to recall if you had any dreams and write them down
When you wake up in the morning: write down how many hours you slept, and if you are still tired or if you feel well rested, and try and recall any dreams that you had
Dream Questions: Do your dreams relate to what
you did the day before? As you start writing down your
dreams do they become able to recall?
“dreaming permits each and every one of us to be quietly and safely insane every night of our lives.” –William C. Dement
Sometimes known as the “father of sleep medicine”
Is a US sleep researcher Founded the worlds first sleep
laboratory which is found at Stanford university
Studies sleep deprivation and treatment of sleep disorders.
The five characteristics of dream consciousness 1. Feel emotion (fear,
happiness, love) 2. be in one place and then in
another with out any travel 3. still have sensation (vision) 4. uncritical acceptance
(normal) 5.difficulty remembering
Nightmares An average college student has
about 24 nightmares a year. Some people have nightmares
as often as once a night Children have more nightmares
than adults People who have experienced
traumatic events are more likely to have nightmares than people that don’t
Dreams “Day residue”- where a current
problem pops into the dream Dreams pull images from your
everyday life to make them seem more surreal, and also images from your past.
Dream Theories In the first psychological theory
of dreams Sigmund Freud he proposed that dreams were confusing and obscure because the dynamic unconscious creates them to be.
In his theory's dreams represent wishes and some only express them in disguised form.
example For Freud's theory in the book
it gives an example on page 250:
A dream about a tree burning down in the park across the street from where a friend once lived might represent a camouflaged wish for the death of the friend. Though wishing for the death of a friend is unacceptable, so it is disguised as a tree on fire.
Not all dreams represent hidden wishes, but some are suppressed thoughts and some are feeling that you may have been hiding or sometimes feelings that you did not necessarily have.
Activations Synthesis ModelThis is the theory that dreams are produced when the mind attempts to make sense of random neural activity that occurs in the brain during sleep.
Different types of dreaming Day dreaming: you are awake, may be
when bored or tired Lucid dreaming: when you realize you are
dreaming and can change the dream to what you like
Recurring dreams: when you get the same dream many different times
Prophetic dreams: dreams that happen in real life, that tell the future
Signal dreams: Epic dreams: when you wake up you feel
like you have realized something, also known as life changing dreams
Progressive dreams: help you face a fear or problem
Mutual dreams: when you and someone else have the same dream
Dreams Meaning: Running away from something
or someone: you need to face something.. Try turning around and asking them why they are chasing you.
Falling: you are afraid of something and are afraid of failing, or paranoid.
Teeth falling out: you are self conscious, afraid of what someone might think of you
