Q

Theories of the function of sleep

Define evolutionary (circadian) theory 🦁

A

The evolutionary theory suggest that sleep is a means of survival for all organisms. Sleep protects the sleeper from harm or death through the minimisation of potential harm we may face in dark & unfamiliar environments

Q

Theories of the function of sleep

Identify the strength 👁😄and limitations (2)💊🔢 of the Restoration Theory

A

Strength -
Addresses our need for sleep and identifies that there are features of both REM and NREM sleep that enhance our psychological and physiological functioning

Weaknesses -
Does not account for the benefit of sleep for mental health
Limited empirical data to support it

Q

Theories of the function of sleep

Identify strengths (2) 🗣, 🌇🌆and limitations(3)🧘‍♀️, 💊🔢 of the Evolutionary Theory

A

Strengths -
Provides an explanation for the purpose of a circadian sleep wake cycle
Explains why our sleep wake cycle is governed by light and over a 24hr cycle

Weaknesses -
No reference to what actually happens when we are sleeping that is beneficial to the body or mind
Does not account for the benefit of sleep for mental health
Limited empirical data to support it

Q

Stages of sleep

Characteristics of REM⏰💭

A

REM is a lighter sleep then stages 3 and 4 NREM (easily awoken), also spend roughly 2 hours dreaming -vivid dreaming occur in REM sleep

17
Q

Stages of sleep

Stage 1 NREM, why it is known as the hypnotic state

A

Transition from being awake to falling asleep
Characteristics by, the sleeper seeing hallucinatory images and the sleeper experiencing involuntary muscle movements (Hypnotic jerks)

18
Q

Stages of sleep

Stage 1 NREM
-Time spend
-Bodily changes -
-
-
-

A
  • 5 to 10 min

- Easily awoken, muscles relax, heart and breathing rate decreases, eyes roll slowly

19
Q

Stages of sleep

Stage 2 NREM ('true sleep') 
-Time spend
-Bodily changes       -
                                  -
                                  -
A
  • 50% of total sleep (20 min)

- Eyes stop rolling, muscles relax, heart and breathing rate decreases (easily awoken)

20
Q

Stages of sleep

Stage 2 NREM (‘true sleep’)
Characteristics🧠

A

By presence of sleep spindles (short rapid burst of brain activity) and k-complexes (sudden high amp waves)

21
Q

Stages of sleep

Stage 3 NREM ('moderately deep sleep')
-Time spend
-Bodily changes -
                            -
                            -
A
  • 10 min

- Heart and breathing rate continues to decrease, body temp drops, eyes dont move

22
Q

Stages of sleep

Stage 3 NREM (‘moderately deep sleep’)
Characteristics

A

Less likely to wake, if awoken they may feel groggy and disorientated.

23
Q

Stages of sleep

Stage 4 NREM (deepest stage)

  • Time spend
  • Sleep phenomena…
A
  • 30 min (prob been asleep for an hour)

- Such as sleep walking, night terrors, sleep talking, and bed wetting

24
Q

Stages of sleep

Stage 4 NREM (deepest stage)
Characteristics⏰

A

Still sensitive to certain stimulus (alarm), we quickly cycle back through the stages, if someone is awoken they will feel disorientated and have low recall of sleep events.

25
Q

Theories of the function of sleep

Define restoration theory🏃‍♀️

A

The restoration theory suggest that we sleep in order to recover from physical and mental depleting activities during the day. Sleep replenishes energy and allow any damaged cells to be repaired.

26
Q

Sleep across the lifespan

What is the approximate required duration of sleep and proportion of REM to NREM sleep for
-Infants

A

Infants (3-24 months):
-Sleep duration decreases to approx 13.5 hours (broken)
REM- approx 35%
NREM- approx 65%

27
Q

Sleep across the lifespan

What is the approximate required duration of sleep and proportion of REM to NREM sleep for
-Adolenscence

A

Adolescence (14-18yrs):
-Sleep decreases to approx 8.5hrs
REM- approx 20%
NREM- approx 80%

28
Q

Sleep across the lifespan

What is the approximate required duration of sleep and proportion of REM to NREM sleep for
-Adults (aged 30-75yrs)

A

Adulthood (30-75yrs):
-Sleep duration decreases to approx 6hrs
REM- approx 20%
NREM- approx 80%
