Effects of sleep disturbances and possible treatment
Define circadian rhythm phase disorder
Used to describe sleep disorders that involve sleep disruptions which occur due to a mismatch between a person’s normal sleep-wake pattern and the sleep-wake pattern required of them ie work schedule.
Effects of sleep disturbance and possible treatment
Explain sleep-wake shifts in adolescence with reference to biological, psychological and social influences, and potential ways to address it.
Refers to a change in your usual sleep wake cycle due to influences.
Social - increased phone usage, stay awake longer
Biological - phone light can result in a lack of melatonin release
Psychological - stress from personal life, school etc.
Ways to address - use phone less, perform stress aleviating activities before sleeping.
Effects of sleep disturbance and possible treatment
Explain how shift work impacts a person’s sleep-wake cycle and potential ways to address
Shift work refers to an occupation which involves working at unusual hours, such as working overnight. This particularly impacts an individual’s sleep-wake cycle, as their circadian rhythm is constantly adapting to their environment, leading to difficulty initiating sleep and waking.
Potential ways to address include: take longer time off between shifts, have set shifts rather than different ones each week.
Effects of sleep disturbance and possible treatment
What are the effects of jet lag on sleep-wake cycle and potential ways to address
Individuals experiencing jet lag may find it difficult to wake up at a time that aligns with the time zone of their environment, or fall asleep at an appropriate time.
Potential ways to address: in the new location expose yourself to light in the first few days, be active, and eat / and sleep at appropriate times.
Sleep deprivation
Define partial sleep
Inadequate sleep based on an individual’s needs. Some quantity of sleep was had in the past 24 hours, but either sleep duration or quality was poor.
(Getting less sleep than you normally require)
Sleep deprivation
Affective effects of partial sleep deprivation
- 😡
- 😭
- 💅
(Emotional state, mood and ability to control emotions)
- increased irritability, due to a reduced ability to regulate emotions
- Depressed mood
- Heightened anxiety
Sleep disorders
How bright light therapy may treat sleep disorders
Exposure sessions to high-intensity artificial
light are used to mimic the role of sunlight.
Melatonin release is controlled by the
suprachiasmatic nucleus, the part of the brain
that responds to light levels received by the
eyes. When exposed to light, such as these
bright lights, the suprachiasmatic nucleus
blocks the release of melatonin, making the
brain feel awake and alert.
Sleep disorders
Bright light therapy can be used for…-
-
- various circadian rhythm phase disorders such as delayed sleep phase disorders, adolescent sleep-wake cycle shifts and jet lag.
- modify or rest the timing of the biological clock to the desirable schedule.
Sleep disorders
What does bright light therapy involve?
Bright light therapy is a method used to adjust a
person’s circadian rhythm through exposure to a
high-intensity light source.
Sleep deprivation
Define total sleep deprivation
An individual not sleeping for a period of at least 24 hours. This involves a complete lack of sleep over one night (pulling an all nighter) or for several nights in a
row.
Sleep deprivation
Behavioral effects of partial sleep deprivation - - - - -
(Changes in actions)
- Reduced motor control, or clumsiness
- Microsleep (very short period of drowsiness)
- Sleep inertia (disoriented feeling, not fully alert)
- Slower reaction times
- absent from work/ school
Sleep deprivation
-
-
(Changes in way we think, learn, reason or process info)
- Illogical or irrational thoughts
- Decreased ability or inability to concentrate and direct attention
- Difficulty completing simple, repetitive tasks
