concentrate on activities of daily living.
Rest and Sleep Terminology

• Rest
• Rest
– implies calmness, relaxation without
emotional stress, freedom from anxiety.
Rest and Sleep Terminology

• Sleep
• Sleep
– an altered state of consciousness,
an individual’s perception of and reactions
to the environment are decreased.
-*Necessary for Protein synthesis

– when a person’s biologic clock coincides with
sleepwake patterns.

Rest and Sleep Terminology

• Electroencephalagram (EEG)
• Electroencephalagram (EEG)
– a graph of the electrical activity of the brain.
-delta slowest of 4 types of waves, low voltage, less activity
-alpha high voltage
-deep sleep waves, dreaming occurs, very hard to arouse
Stages of Sleep

1. Non-rapid eye movement (NREM).
The parasympathetic branch of the
autonomic nervous system dominates
and results in a decrease in:
• Heart rate
• Respiratory rate
• Blood pressure
• Metabolic rate
• Body temperature
• Slow brain waves
NREM STAGE =Four Stages

• Stage I
• Stage I – transitional stage between
wakefulness and sleep. A relaxed state that last
only minutes, eyes roll from side to side, the
person can be aroused easily.
NREM STAGE =Four Stages

• Stage II
• Stage II – a person falls into a stage of light
sleep but can be aroused easily, eyes still, body
temp. falls.
NREM STAGE =Four Stages

• Stage III
• Stage III – arousal becomes difficult, snoring
may occur.
NREM STAGE =Four Stages

• Stage IV
• Stage VI – greatest depth of sleep (delta sleep).
Arousal is difficult, restores the body physically,
eyes roll and dreaming occurs.
Stages of Sleep

2. Rapid eye movement (REM) sleep
–not as restful, dreams are usually remembered, sleep
is characterized by a stage that is more difficult to arouse a person. It consumes 20% to 25% of a normal adult’s nightly sleep.
• General skeletal muscle tone and deep tendon reflexes are depressed
• Increased heart rate
• Increased respiratory rate
• Increased blood pressure
• Increased metabolic rate
• Increased body temperature
• Highly active brain (paradoxical)
REM Sleep

• Believed to be essential to________
• Believed to be essential to mental and emotional
worst survival – < 3 to 4.5 hours or > 8.5 hours.
Influences of Rest and Sleep
Influences of Rest and Sleep
• Age
• Comfort
• Illness
• Drugs
• Life Style

• Sedatives introduced in the early 1900’s
• First prescribed to reduce tension and
• Usually increases total sleep time
• May decrease REM sleep Developmental Patterns
• Infants – REM sleep
• Infants – REM sleep constitutes much of the
sleep cycle. Newborns sleep an average of 16
hours, infants 10-12 hours (can be as much as
22 hours).
• Toddlers
• Toddlers – begin with 12 hours with two naps
during the day and end with 8 hours with one
nap during the daytime. Normal sleep-wake
cycles are established.
• Preschoolers – REM sleep pattern
• Preschoolers – REM sleep pattern is similar to
the adult. Can sleep 11-12 hours at night, the
average is 12. Wake up frequently at night.
Developmental Patterns
• School-age –
• School-age – sleep needs increase when
physical growth peaks. May require 8-12
hours per night.
Developmental Patterns
• Adolescents –
• Adolescents – growth spurts necessitate
the need for more sleep. Restless sleep is
contributed to stress of school, activities,
employment, nocturnal emission (wet dreams). Many adolescents do not get enough sleep.
Developmental Patterns
• Young adults –
• Young adults – average 8 hours of sleep.
Sleep is affected by physical health, type
of occupation, exercise, and lifestyle
Developmental Patterns
• Middle-age adults
• Middle-age adults – 6-8 hours, decrease in
total sleep time and a decrease in delta
sleep. The total time awake in bed
Developmental Patterns
• Older adults –
• Older adults – average 5-7hours. Sleep is less sound, stage VI sleep may be absent, periods of REM sleep is shorter. May experience more difficulty falling asleep and c/o of problems
staying asleep. There is a decline in physical activity, psychological factors, effects of drug
therapy, or environmental factors may be implicated as causes of inability to sleep.
Sundowner’s syndrome – confusional state that tends to appear at dusk (R/T change in circadian
rhythms )

mid-afternoon doses may more effectively
prevent attacks that commonly occur at night
during sleep.
Influences of Drug Therapy on Rest and Sleep
• Anti-hypertensive medications
• Anti-hypertensive medications – may need
adjustment to provide peak protection during
early-morning hours, when heart attacks are
more common. Beta-blockers have been know
to cause insomnia and nightmares.
Influences of Drug Therapy on Rest and Sleep

administered at certain times during the day.
Note: A client withdrawing from narcotics,
tranquilizers, amphetamines and antidepressants gets more REM sleep and may experience nightmares.

effect of these patterns on everyday functioning, the patient’s use of sleep aids,
and the presence of sleep disturbances and
contributing factors.
. Use open ended questions if you suspect potential problems.

Sleep Rest Facts

. Snoring
. Snoring is not ordinarily a sleeping disorder.
Snoring accompanied by apnea can present
a problem.
. Nocturnal Myoclonus
. Nocturnal Myoclonus – marked muscle contraction that results in the jerking of one or both legs during sleep. The jerking lasts about 28 seconds on the average, may arouse the sleeper, and contribute toinsomnia.
. Insomnia
. Insomnia – difficulty falling asleep and/or staying asleep. It is more common in females, people with a history of depression, and people older than 60.
Temporary insomnia can be caused by noise or a
stressful event like the loss of a job or a death in
the family. Certain medication can keep you
awake, those that treat colds and allergies, heart
disease, blood pressure, and pain. Habits that sabotage our sleep include ingestion of alcohol and eating too close to bed time.
. Additional Medications Affecting Sleep.

the side effect of paradoxical excitement.
Higher doses will not produce sedation. A
non-barbiturate sedative or hypnotic may
be prescribed in its place.
