Cycle Interruptions. As you sleep, your brain cycles through four stages of sleep. Stages 1 to 3 are what's considered non-rapid eye movement (NREM) sleep, also known as quiet sleep.

A parasomnia is one of a group of sleep disorders in which unwanted, disruptive motor activity and/or experiences during sleep play a role. Parasomnias can occur in either REM or NREM phases of sleep. Sleepwalking, restless leg syndrome, and night terrors are all examples of parasomnias (Mahowald & Schenck, 2000) Normal sleep pattern vs. narcolepsy. The normal process of falling asleep begins with a phase called non-rapid eye movement (NREM) sleep. During this phase, your brain waves slow considerably. After an hour or so of NREM sleep, your brain activity changes, and REM sleep begins. Most dreaming occurs during REM sleep

NREM 2 is the longest of the four sleep stages. NREM 3: This stage marks the beginning of slow-wave, or deep, sleep. Heartbeat, breathing rates, and brain wave activity will decrease to their lowest possible levels and the muscles will completely relax. NREM 3 is a longer stage when you first fall asleep but it will gradually shorten throughout. Sleep apnea is another disorder that impacts our quality of sleep. People with sleep apnea randomly stop breathing while they are asleep and are frequently awakened throughout the night. Lastly, night terrors, which typically impact children, occur in NREM-3 and thus differ from regular dreams and nightmares. This may be characterized by incoherent chatter or physical movement NREM stage 3 sleep is often referred to as deep sleep or slow-wave sleep because this stage is characterized by low frequency (less than 3 Hz), high amplitude delta waves (Figure 4.10).These delta waves have the lowest frequency and highest amplitude of our sleeping brain wave patterns. During this time, an individual's heart rate and respiration slow dramatically, and it is much more.

Sleep can be divided into two sleep states or types and there is a sequential rotation between these two sleep states several times (5 to 6 times) during a night. These rotations are generally between 90 to 100 minutes per cycle. These two major phases of sleep are: Rapid eye movement (REM) sleep; Non- rapid eye movement (NREM) sleep Circadian rhythms are the cycles that tell the body when to sleep, wake, and eat—the biological and psychological processes that oscillate in predictable patterns each day.

Narcolepsy is a disorder that disrupts sleep-wake processes. Its primary symptom is excessive daytime sleepiness (EDS), which occurs because the brain is unable to properly regulate wakefulness and sleep.. Normal sleep unfolds through a series of stages, with rapid eye movement (REM) sleep occurring in the final stage, usually an hour or more after falling asleep Sleep is a state that is characterized by changes in brain wave activity, breathing, heart rate, body temperature, and other physiological functions. Depending on the sleep stage, different physiological functions may be more active and variable (for example, during REM sleep), or less active and more stable (for example, during NREM sleep) NREM is sometimes called quiet or inactive sleep because, in general, proceeding from stage 1 NREM to stage 4 NREM causes a progressive decrease in activity in the brain and body.
