Benefits of proper mount of sleep - ANSWER - Improves memory
- Improves learning
- Improves concentration
- Improves health in general
Does the body shut down when we sleep? - ANSWER no, sleep is an active process.
We are just not conscious of what happens in our bodies.
What controls the sleep-wake cycle? - ANSWER It is primarily controlled by the
interaction of the Sleep Homeostatic Drive (Accumulation of adenosine and
"somnogens" such as cytokines) and the Intrinsic Circadian Timekeeping System (The
effect of light and darkness on the sleep wake cycle and timely release of hormones)
How many types of sleep are there? - ANSWER There are two. NREM and REM
NREM is broken into how many stages? - ANSWER 3 stages.
-N1 which is light sleep. Usually the first stage of sleep.
- N2 still fairly light sleep and covers the majority of sleep we get during the night.
- N3 Deep Sleep (AKA slow wave sleep)
Physiological Variables in NREM sleep - ANSWER - Heart rate is regular
- Respiratory rate is regular
- BP is regular
- Skeletal muscle tone is preserved
- Brain O2 consumption is reduced.
- Response to CO2 is the same as wake
- Response to O2 is the same as W
- Penile tumescence, vaginal engorgement is infrequent
- Temperature is homeothermic
Homeothermic - ANSWER having a body temperature that is constant and largely
independent of the temperature of its surroundings. Stable body temperature of about
98.6F/ 37 C
Physiological variables during REM sleep - ANSWER - Heart rate is irregular
, - Respiratory Rate is irregular
- Blood Pressure is variable
- Skeletal muscle tone is absent
- Brain O2 consumption is increased
- Response to CO2 is depressed
- Response to O2 is same as W
- Penile tumescence, vaginal engorgement is frequent
- Temperature is poikilothermic.
Poikilothermic - ANSWER Body temperature varies with environmental temperature.
How many sleep cycles can we go through in one night? - ANSWER in a typical night,
one may go through 4-5 cycles of sleep.
When does the majority of deep sleep occur? - ANSWER Early in the sleep period (first
third of the night).
Periods of REM sleep - ANSWER Periods of REM sleep are initially short, but become
longer in duration as the night progresses.
What is NREM sleep believed to be for? - ANSWER NREM sleep is believed to help
restore the body/
What is REM sleep believed to help? - ANSWER REM sleep is believed to help restore
the mind
When do we obtain the best sleep? - ANSWER When it is consolidated
Does the amount of sleep we need throughout the life cycle changes? - ANSWER Yes,
it does.
Infant sleep - ANSWER - Not born with same sleep functions as adults.
- Sleep stages are not fully developed.
- Quite sleep- NREM like
- Active Sleep- REM like
- Indeterminate sleep (mixed)
Infant 0-3 months - ANSWER -Trace alternant pattern of quite sleep (NREM)
-Continuous medium activity (active sleep and wakefulness)(REM)
- Intermediate sleep
- Sleep onset REM is common and may continue up to 6 months of age
- Sleep is approximately 50% quite sleep, 50% active
- Cycle between active and quite sleep about every 45-60 minutes.
Transitions may be difficult to identify.
