Q

What is the biological reason for why we sleep?

A

Melatonin is a hormone that is released by the pineal gland-particularly at night time-makes us feel drowsy+sleepy
Melatonin is released when environment is darker-eyes receive info and this is sent via neurons to the suprachiasmatic Nucleus then sends a signal to the pineal gland to release melatonin
When it become lighter melatonin stops and becomes stored

16
Q

The suprachiasmatic nucleus is

A

An area of the hypothalamus that is responsible for regulating an idividuals sleep-wake patterns

17
Q

The Pineal gland is

A

Structure of the brain that regulates sleep/wake cycle and releases our sleep hormone-melatonin

18
Q

What is the circadian rhythm

A

fancy word for body clock
biological that processes the timing of activity of body systems over a 24 hour period

19
Q

What is the ultradian rhythm

A

Biological process that co-ordinates the timing of activity of body systems over periods of less than 24 hours

20
Q

What are some processes that follow an ultradian rhythm

A

-heart rate/digestion/blood pressure/appetite

21
Q

What happens to your body when you sleep?

important-learn this!

A

-body temperature decreases
-heart rate and breathing rate decreases
-blood preasure decreases
-growth hormone is released
-body restores itself

22
Q

The 2 different types of sleep are

A

Rapid eye movement and non rapid eye movement

23
Q

What happens during REM sleep

A

most dreaming occurs
increased eye movemnt
increased brain activity
occurs at the end of sleep sycle
blood preassure rises/breathing comes quicker
muscle paralysis/stop actin gout dreams
approx.20-25% of sleep episode for most age groups

24
Q

Non Rapid eye movement

A

Divided into 3 stages and each have a distinct chnage in brain activities
stage 1:traditional
stage 2-light
stage 3 :deep

25
Q

WHat happens in the 3 stages of NREM sleep

A

traditional-very light in the middle of wakeness and sleep-physiological responses begin to slow down
light-can still be woken up easily however bursts of brain activity help resist being woken by environmental stimuli(noise)
deep-most difficulty to wake up-brain activity is at its slowest

26
Q

How do our sleep episodes work?

A

fall asleep-go into NREM stage 1
fall into deeper sleep S2
deepest sleep S3
work up stages
once you have gotten to stage one you go into REM sleep
whole cycle takes 90-120mins
repeat

27
Q

How does our sleep need to change as we age?

A

sleep gets less with age
normal for children to daytime nap 3-5yrs
teenagers would want to go to bed later and sleep in
older people spend more time in bed but their sleep requirements are similar to early aduly life

28
Q

how much sleep you need varies form person to peson depending on….

A

1.genetics
2.gender
3.age
4.activity level

29
Q

What happens if we dont get enough sleep

A

higher level of anxiety
higher risk of storke
increased risk of heart disease
risk of injury

30
Q

How much sleep will a newborn need?

34
Q

how much sleep does a young adult need

A

approx 7.75 hours 20% REM 80% NREM

35
Q

How much sleep does a middle adulthood need?

A

approx.7-8 hours 20% REM 80% NREM

36
Q

How much sleep does an older adult need?

A

apporx. 6 hours 20% REM 80% NREM

37
Q

What is sleep deprivation?

A

inadequate or insufficient sleep sustained over a period of time

38
Q

WHat happens if you are sleep deprived.

A

ability to learn,memory ,reaction time and mood is effected
