- Factors affecting insomnia
- Is the condition where an individual has problems falling asleep and/or staying asleep
- The sleep that occurs tends not to be deep
- Is easily disturbed
- Research has shown that insomnia can be affected by many different things like:
- Stress
- Environmental factors
- Sleep hygiene
- Sleep apnoea
- Personality traits
- Interfering with the natural progression of brain activity
- The sleep that occurs tends not to be deep
- Any stimuli such as bright lights, loud noises, very hot or cold rooms, an uncomfortable bed, or a snoring companion
- contribute to insomnia
- They interfere with the brains natural calming down of neural activity
- A change in the location where on sleeps
- Boost brain activity - lead to insomnia
- Aggravate the impacts of jet lag
- However
- It cannot be proved that it is the change in location not the excess stimulation from being in a foreign sleeping environment
- However
- Aggravate the impacts of jet lag
- Boost brain activity - lead to insomnia
- There is a high degree of ID when it comes to environmental factors
- As some people may sleep best in a cold room
- Whereas
- Some may not be able to sleep at all in such environments
- Whereas
- As some people may sleep best in a cold room
- Regular loud noises may become comforting to an individual
- Therefore
- We begin to learn what we are used to and some environmental factors that may have a negative affect on sleep for some individuals may be positive for others
- Therefore
- contribute to insomnia
- The importance of light as a zeitgeber
- Sifffre's Cave Study highlighted
- Light upon the suprachiasmatic Nucleus
- Recent research has shown that even low intensity light, especially short wavelength, can inhibit the production of melatonin which is though to trigger sleep
- TV's Monitors produce light of this character
- common cause of insomnia
- However
- It is difficult to measure this effect in the real world
- It may be the content of the TV or computer
- Cognitively stimulating rather than a primarily physiological effect
- However
- This cannot take away from the fact that there is an epidemic of sleeplessness in the modern work
- However
- Cognitively stimulating rather than a primarily physiological effect
- It may be the content of the TV or computer
- It is difficult to measure this effect in the real world
- TV's Monitors produce light of this character
- Sleeplessness may be due to electronic devices e.g. but it may also be due to other enviro factors e.g.
- People work through the night = disrupting sleep patterns
- Proven by the increase in prescription drugs
- People work through the night = disrupting sleep patterns
- Sifffre's Cave Study highlighted
- Stress
- Acute stress
- exam
- new job
- Brian activity is heightened
- The sympathetic AND is active and so the parasympathetic ANS cannot switch off
- Transitory, so when it is over normal sleep should resume
- However
- Chronic stress
- However
- The stressor persists
- Sympathetic ANS activity remains high
- Lead to long-term disrupted sleep as adrenaline is being produced which keep the individual awake and inhibits relaxation
- This increases the level of stress
- However
- stress can also cause health problems
- therefore
- making it difficult to distinguish cause and effect
- All these issue culminates with individual thinking about the stressor
- Inhibits reticular activation
- A neutral distractor is necessary
- Counting sheep
- An act of free will to overcome insomnia
- Conscious intentionality to adapt a method to get to sleep
- A neutral distractor is necessary
- Inhibits reticular activation
- All these issue culminates with individual thinking about the stressor
- making it difficult to distinguish cause and effect
- therefore
- stress can also cause health problems
- However
- This increases the level of stress
- Lead to long-term disrupted sleep as adrenaline is being produced which keep the individual awake and inhibits relaxation
- Can lead to emption focused responses
- Smoking
- Drinking
- Examples of poor sleep hygiene
- Smoking
- these impact directly upon the individuals health and insomnia
- Examples of poor sleep hygiene
- May be another factor contributing to the epidemic
- Increase in drugs prescribed for stress
- Travel
- Jet lag
- Travel
- However
- Due to the large no. of factors that may be adding to the epidemic
- Results are correlational
- Don't know the direction of the effect
- Nevertheless
- Research points to the importance of good sleep hygiene and the necessity of instilling this in children from an early age
- Results are correlational
- Due to the large no. of factors that may be adding to the epidemic
- Increase in drugs prescribed for stress
- Acute stress
- Conclusion
- Unfortunately many studies into insomnia problem with sample bias
- Small sample sizes
- Self-report
- Social desirability bias
- Not understanding the question
- Individual difference
- Lacks generalisability
- Questionable whether we can be sure of the direction of effect
- All results are correlational
- Example
- Stress and insomnia have a direct link
- there is an association
- There is a correlation between the data
- We do not know if stress causes insomnia or the insomnia causes the stress
- Stress and insomnia have a direct link
- Example
- All results are correlational
- Unfortunately many studies into insomnia problem with sample bias
- Is the condition where an individual has problems falling asleep and/or staying asleep
