    Study Notes

    Sleep Stages

    • NREM (Non-Rapid Eye Movement) Stage 1:
      • Occurs when you first fall asleep; half asleep/half awake
      • Lasts for around 10 minutes (5%)
      • Very easy to be woken up when in Stage 1 of sleep
      • Brain activity goes from Alpha waves to Theta waves
    • NREM Stage 2:
      • Lasts for about 30 to 60 minutes
      • Accounts for 50% of total sleep time
      • Harder to be woken up from in this stage of sleep
      • May begin to see Delta waves in this stage
    • NREM Stage 3:
      • Deep sleep stage
      • Hardest stage to wake up from
      • Lasts for about 20 to 30 minutes during the first cycle of sleep and then less and less in each cycle
      • Accounts for about 20% of total sleep time
    • REM (Rapid Eye Movement) Sleep:
      • REM sleep is the final stage in a sleep cycle
      • During this stage:
        • Heart rate, breathing, and blood pressure all fluctuate
        • Eyes move rapidly
        • Muscles twitch
      • A fast pattern of brain waves can be observed
      • Dreaming occurs
      • Most muscles are paralyzed during this stage so that you can’t act out your dreams
      • Accounts for 25% of total sleep time

    Circadian Rhythms

    • Circadian rhythm: a biological clock that helps control many aspects of your body, including your sleep/wake cycle
    • It controls the timing of sleep-wake patterns and the duration of sleep
    • If body temperature doesn’t drop, it’s a risk factor for heart disease
    • Affected by:
      • Jet lag
      • Daylight savings
      • Shift work
    • Takes days to adjust

    Sleep Theories: Why Do We Sleep?

    • Restoration:
      • The proper functioning of our immune system is dependent upon sleep
      • Sleep restores the body
      • Without sleep = collapse
    • Ontogenesis:
      • REM sleep allows for the development of brain through preventing apoptosis in the developing brain
      • The more REM sleep = less brain cell death
      • REM sleep helps with brain maturation through neural activity in the developing brain
    • Learning and Memory:
      • Many studies have shown that sleep affects memory, mainly that sleep deprivation hinders working memory

    Sleep Disorders

    • Divided into 3 categories:
      1. Dyssomnias
      2. Parasomnias
      3. Sleep Disorders Associated with Mental, Neurologic, or Other Medical Disorders
    • Dyssomnias:
      • Disorders that produce either difficulty initiating or maintaining sleep or excessive sleepiness
      • Divided into three groups of disorders:
        • Intrinsic sleep disorders
        • Extrinsic sleep disorders
        • Circadian rhythm sleep disorders
      • Related to stress
    • Parasomnias:
      • Disorders that intrude into the sleep process and are not primarily disorders of sleep and wake states per se
      • Manifestations of central nervous system activation
      • Divided into 3 subgroups:
        • Arousal Disorders
        • Sleep-Wake Transition Disorders
        • Parasomnias Usually Associated with REM Sleep
        • Other Parasomnias
      • Not affected by stress, related to nervous system

    Insomnia

    • Types:
      • Mild Insomnia
      • Moderate Insomnia
      • Severe Insomnia
    • Characteristics:
      • Insufficient sleep and not feeling rested
      • Almost nightly, nightly, or nightly
      • Social/Occupational Impairment: very little or none, mild to moderate, severe
      • Restless, Irritable, Daytime Fatigue: sometimes, always, severe

    Psychophysiologic Insomnia

    • Physiological/psychological arousal preventing sleep
    • Stress and worry about being able to go to sleep inhibits sleep from occurring
    • Sleep is now associated with stress
    • Bed is now associated with a place where you cannot relax
    • No phone, no TV

    Hypersomnia

    • Characterized by periods of extreme somnolence; 18 to 20 hours a day
    • Can last several days to several weeks
    • More common in males than females

    Bruxism

    • Grinding and clenching teeth while sleeping
    • Results in tooth wear, jaw pain, headaches, and complaints from co-sleepers
    • 5% of population grind their teeth
    • Related to stress

    Sleep Enuresis

    • Also known as “Bed-Wetting”

    • Must be persistent after the age of 5

    • Very rare in adults

    • Bidirectional Relationship of Stress & Sleep:

      • HPA axis regulation and changes in sleep have a bidirectional relationship
      • Daytime stress leads to poor sleep, which can lead to increased daytime stress### Stress and Sleep

    • The bidirectional relationship between stress and sleep can create a downward spiral, where stress leads to poor sleep, and poor sleep leads to increased daytime stress.

    • Allostatic load, a measure of the body's capacity to handle stress, can decrease due to stress, making it easier to get sick.

    • HPA axis regulation and changes in sleep have a bidirectional relationship, with daytime stress leading to poor sleep, and poor sleep leading to increased daytime stress.

    HPA Axis and Sleep

    • Increased corticosterone and ACTH following sleep deprivation have been found in studies.
    • Sleep problems can lead to higher cortisol levels in response to a stressor, resulting in daytime sleepiness and sleep-wake problems.

    Stress and Sleep Disorders

    • Stress can lead to insomnia, characterized by difficulty initiating or maintaining sleep, or excessive sleepiness.
    • Stress can also contribute to hypersomnia, characterized by periods of extreme somnolence, and bruxism, characterized by grinding and clenching teeth while sleeping.
    • Nocturnal enuresis, also known as bed-wetting, can be triggered by stress in individuals who have previously recovered from it.

    Sleep Disorders

    • Dyssomnias are sleep disorders that produce either difficulty initiating or maintaining sleep or excessive sleepiness.
    • Parasomnias are disorders that intrude into the sleep process, such as arousal disorders, sleep-wake transition disorders, and parasomnias usually associated with REM sleep.
    • Sleep disorders associated with mental, neurologic, or other medical disorders include insomnia, hypersomnia, and sleep enuresis.

    Personality and Sleep

    • Personality may mediate the relationship between stress and sleep, with neuroticism (N) being the personality trait most closely resembling anxiety.
    • High neuroticism is linked with poor coping with stress, poor sleep, and more daytime sensitivity to poor sleep.
    • Conscientiousness (C) may mediate the consequences of N and bad sleep, with high-N, low-C individuals being most sensitive to the effects of bad sleep.

    Rumination and Sleep

    • Rumination, continuously thinking about problems, can negatively impact sleep quality.
    • High-trait ruminators in rumination conditions report poor sleep quality and more sleep disturbances.
    • Cognitive pre-sleep activity may increase arousal levels, leading to poor sleep.
