Sleep Basics and General Adaptation Syndrome

Introduction to Sleep Basics and General Adaptation Syndrome

  • Speaker: Meris
  • Focus: Sleep basics, sleep disorders, General Adaptation Syndrome (GAS)
  • Reference: Following along with Fundamentals of Nursing flash cards available at leveluprn.com
  • Starting point: Card 62 of the flash cards

Circadian Rhythm

  • Definition: The circadian rhythm refers to the natural wake and sleep cycle of the human body.
  • Function: Regulates the time we wake up in the morning and the time we go to sleep at night.
  • Influencing Factors:
      - Light exposure
      - Environment
      - Age
      - Illnesses or disease processes

Stages of Sleep

  • Overview: Sleep is divided into stages, primarily categorized into stages 1 through 3 and REM (Rapid Eye Movement) sleep.

Stage 1

  • Characterized as light sleep, transitioning from wakefulness.

Stage 2

  • Also a light sleep stage, the body begins to prepare for deep sleep.

Stage 3

  • Description: Very deep sleep stage.
  • Vital Signs: At their lowest compared to other sleep stages.
  • Difficulties: Hard to awaken someone in this stage.

REM Sleep

  • Timing: Occurs about 90 minutes after falling asleep.
  • Characteristics:
      - Eyes move rapidly under closed eyelids.
      - Vital signs increase compared to stage 3 (heart rate and blood pressure rise).
      - This is the phase where vivid dreaming occurs.
  • Difficulties: Hard to awaken someone during this phase as well.

Sleep Disorders

  • Personal Experience: The speaker has struggled with sleep disorders since childhood, emphasizing the significant impact on recovery from illness and managing pain.
  • Key Sleep Disorders:
      - Insomnia:
        - Difficulty falling asleep, staying asleep, or both.
        - Can manifest in various forms among individuals.
      - Narcolepsy:
        - Excessive daytime sleepiness.
        - Patients may fall asleep unexpectedly during waking hours.
      - Sleep Apnea:
        - Characterized by pauses in breathing during sleep.
        - Irregular breathing patterns are common.
        - Treatment often involves devices such as CPAP (Continuous Positive Airway Pressure) to keep airways open.

Sleep Hygiene

  • Definition: Practices that promote consistent, restful sleep, which are critical for patient education.
  • Advice:
      - Maintain a regular sleep schedule to establish routine.
      - Create a sleep environment that is cool, dark, and quiet.
      - Avoid afternoon naps, as these can delay nighttime sleep.
        - Important to differentiate between an early morning nap and an afternoon nap.
      - Limit alcohol and caffeine intake, especially later in the day; personal anecdote highlights avoiding caffeine after noon.
      - Engage in regular exercise, but refrain from exercising within three hours of bedtime for it to be beneficial to sleep quality.

General Adaptation Syndrome (GAS)

  • Definition: A model describing physiological changes in the body during stress, applicable to various stressful situations such as nursing school.

Alarm Phase

  • Response: Initial reaction to stress, triggering the fight or flight response.
  • Effects:
      - Increase in heart rate and blood pressure.
      - Elevated cortisol levels.
      - Feelings of panic and stress.

Resistance Phase

  • Description: The body adapts to stressors and begins to function at a new equilibrium.
  • Physiological Changes: Vital signs may normalize, but cognitive impacts such as poor concentration, irritability, and frustration can occur.

Exhaustion Phase

  • State: The body becomes unable to cope with stressors.
  • Consequences:
      - Feelings of fatigue, depression, and anxiety.
      - Risk of impaired immunity due to prolonged stress.
  • Importance: It is vital to educate patients on stress management to prevent reaching exhaustion.
