25%

if not, it will be made up in subsequent nights

27
Q

What proportion of REM sleep constitutes a Newborns sleep per night?

A

50%

28
Q

What happens when you’re in REM sleep?

A

a. So named, due to the darting eye movements that characterise it
b. Pulse and blood pressure quicken,
c. Respiration becomes faster and irregular
d. Most dreams occurs in REM sleep
EEG- Active patterns resembling waking consciousness
Beta waves (goes back to same EEG activity as when alert)

29
Q

What is shown in the EEG when your in the REM sleep stage?

A 
Active pattern resembling waking consciousness
Beta waves (goes back to same EEG activity as when alert)
30
Q

What other period of sleep is the same as when awake?

A

REM sleep

both have beta waves - active patterns resemble waking consciousness

31
Q

In what phase of sleep do dreams occur?

A

RE

32
Q

When does REM sleep occur?

A 
90 min (1 hour and half ) after falling asleep
During the early stages of morning, REM sleep lasts for 1 hour period at a time - tend to remember these dreams
33
Q

Is sleep pattern set between all humans?

A

no sleep pattern is not set

the graphs of EEG differ between people

34

What is delta sleep considered to be?

A

Stage 3 and 4 of NREM sleep

37
Q

What ar the 4 main bodily changes that occur during REM sleep?

A
  1. Darting eye movements
  2. Pulse and blood pressure quickens
  3. Respiration becomes faster and irregular
  4. Most dreaming occurs in REM sleep
38
Q

What is each sleep stage defined by?

A

characteristic patterns of brain activity

39
Q

What are the characteristic patterns which define being Awake on the EEG?

A

Low voltage

irregular and fast

40
Q

What are the characteristic patterns which define being Drowsy on the EEG?

A

8 - 12 cps

alpha waves

41
Q

What are the characteristic patterns which define Stage 1 on the EEG?

A

3 - 7 cps

Theta waves

42
Q

What are the characteristic patterns which define Stage 2 on the EEG?

A

12 - 14 cps
Sleep spindles
and K complexes

43
Q

What are the characteristic patterns which define Stage 3 and 4 on the EEG?

A

1/2 - 2 cps
delta waves
75 mV

44
Q

What are the characteristic patterns which define REM sleep?

A

low voltage

Random, fast, with Saw tooth waves

45
Q

What is the typical pattern the stages of sleep?

A

A typical patterns of the stage of sleep during a single night includes deeper sleep in the early cycles, but more time in REM in the later cycle

46
Q

What occurs during the early cycles in a typical pattern of the stages of sleep?

A

Deeper sleep

47
Q

What occurs during the later cycles in a typical pattern of the stages of sleep?

A

more time in REM

48
Q

What are some practical ways to assist with sleep problems?

A

sleep hygiene

49
Q

What is Sleep hygiene?

A

Dr Peter Hauri first used the term ‘sleep hygiene’ to describe what patients can do to eliminate sleep - interfering factors, and promote better health
Sleep hygiene refers to the practice of following guidelines/techniques to ensure restful, effective sleep
(routine set up to try and improve the outcome of sleep)

50
Q

What are 11 factors that affect sleep?

A
  1. Caffeine (stimulant)
  2. Nicotine (stimulant)
  3. Alcohol (or other drugs and/or medication)
  4. Sleep environments: temperature (summer
51
Q

Why does the factor “Use of electronic devices” affect sleep?

A

It is the bright light

Stops the production of melatonin

52
Q

What are things which can reduce jet lag?

A

Melatonin tablets

LED light box

53
Q

Is it easier to sleep in Summer or Winter?

A

Factor affecting sleep is Sleep environment : Temperature

Hotter in summer and therefore harder to sleep/more restless

54
Q

What are the age related factor’s influence on sleep?

A

Baby = sleeps about 20 hours
Toddler = sleeps about 17 hours
Child = starts to consistently sleep about 10-12 hours
Teenager/adult = Night focused circadian rhythm = up later, wake up later
Old adults = Need LESS sleep

55
Q

How can thinking style be a factor which effects sleep?

A

Thinking style = affects Lifestyle = affects stress levels = affects ability to sleep

56
Q

What 8 things can you do to improve sleep?

A
  1. Make your bedroom haven for sleep only
  2. Reduce the amount of light (half an hour before sleep)
  3. Turn off Mobile phones/ computers
  4. Limit caffeine (watch out for caffeine after lunch)
  5. Reduce alcohol
  6. Create a Sleep routine
  7. Use relaxation techniques (meditation - be mindful and don’t think about stresses)
  8. Seek out morning light to re/set your circadian rhythm
57
Q

What does it mean by improving sleep by making your bedroom a haven for sleep only?

A

Do not do anything in your room (studying, reading etc) especially not on your bed, as that reinforces that your bedroom and your bed in particular is only for sleeping

58
Q

What are relaxation techniques?

A

Relaxation can be a valuable technique for someone with sleeping problems
Deep relaxation is a distinct physiological state that is the exact opposite of the way the body reacts under stress or anxiety
Relocation can be used as a part of “wind-down” period before bed or helpful if people find they are waking in the night and experiencing difficulty getting back to sleep
