Study Notes

Stages of Sleep

Stage 1: Transitional phase between wakefulness and sleep; brief duration; low-amplitude, rapid brain waves; vivid imagery may occur, but no true dreaming.
Stage 2: Deeper sleep than Stage 1; characterized by slower waves and sleep spindles; comprises about half of total sleep; awakening is more difficult.
Stage 3: Defined by slow brain waves with greater variation in amplitude than Stage 2.
Stage 4: Deepest sleep stage; minimal response to external stimuli; critical for restorative processes.
REM Sleep: Accounts for 20% of sleep; increased physiological activity includes heart rate, blood pressure, and breathing; dreaming occurs; major muscle paralysis; REM deprivation leads to rebound in REM sleep duration.

Sleep Cycles

First half of the night dominated by stages 3 and 4 (deep sleep); second half dominated by stages 1, 2, and REM sleep.
Sleep requirements vary across the lifespan; generally decreases with age.

Sleep Disorders

Insomnia: Difficulty falling or staying asleep; affects up to one-third of individuals; often situational; treated through stimulus control.
Sleep Apnea: Breathing difficulties during sleep; affects about 20 million people; common in overweight, middle-aged men; may lead to severe sleep disruption and health risks.
Nightmares: Vivid, frightening dreams occurring during REM sleep; experienced by nearly everyone; chronic nightmares may indicate underlying emotional issues.
Night Terrors: Sudden awakenings during non-REM sleep; common in children; intense fear and confusion; treatment often involves waiting for age-related reduction.
Narcolepsy: Characterized by excessive daytime sleepiness and uncontrolled sleep episodes; affects 1 in 1000 people; linked to reduced quality of life; treated with naps and stimulants.
Sleeptalking & Sleepwalking: Occur during stage 4 sleep; more common in children; usually harmless; awareness of environment is minimal; treatment includes awakening before incidents or psychotherapy.

Tips for Better Sleep

Engage in regular exercise, ideally in the afternoon.
Maintain a consistent bedtime routine.
Consider warm milk before bed to aid sleep.
Avoid stimulants like alcohol and caffeine close to bedtime.
Refrain from heavy meals before sleep.
Limit bed time outside of sleep; avoid stressful thoughts before bed.

Dream Characteristics

Dreams consist of sequences of vivid and colorful images, often with distorted space-time relationships.
Commonly charged with emotion and can alternate between pleasurable and frightening experiences.
Not everyone remembers their dreams; non-recallers may still dream as frequently as those who do.

Meditation

A mental state achieved through techniques like controlled breathing, focus restriction, and eliminating external stimuli.
Transcendental Meditation (TM) is a commercial adaptation of traditional Yoga meditation practices.
Elements for effective meditation include a quiet environment, comfortable position, mental focus, and a passive attitude.
Psychological effects include feelings of calm and well-being; physiological effects include changes in brain activity, decreased heart rate, and reduced oxygen consumption.
Utilized in clinical psychology to treat anxiety and stress-related disorders.
