As you sleep, your body cycles through non-REM and REM sleep. Stage 1 non-REM sleep a person in this stage is between being awake and asleep or is in a state of very light sleep. REM takes up more of the cycle as the night goes on. Each stage can last from 5 to 15 minutes. Non Rapid Eye Movement, a recurring sleep state during which rapid eye movements do not occur and dreaming does not occur. Non-REM Sleep . As the muscles relax, you might experience a sudden jolt combined with During this stage is when most sleep walking occurs. During stage 1 the person is still aware and gravitates from being awake or entering a very light sleep. When normal individuals first fall asleep, they enter Stage 1 (sleep drowsiness) and then progress through Stages 2, 3, and 4 of NREM sleep. EEG s during N2 sleep show sleep spindles and K complexes on a background of relatively low-voltage, mixed-frequency EEG activity. Sleep is organized into different stages, which can be broadly categorized into rapid eye movement (REM) and non-rapid eye movement (NREM).When a person experiences rebound sleep, they can experience an increase in REM sleep, This relaxation allows your muscles to be relieved of tension and can reduce pain. Non-REM sleep includes three different stages. The studies are done to find out what is causing your sleep problems. If sleep remains uninterrupted it will progress to stage 2 sleep. NREM Stage 1 takes 1-5 minutes to complete. In addition, stage 1 sleep involves a marked decrease in both overall muscle tension and core body temperature. There are three phases of non-REM sleep.

Your heartbeat and breathing slow to their lowest levels during sleep. It has minimal restorative impact and you can be easily awakened during it. D.

The REM phase is also known as paradoxical sleep (PS) and sometimes desynchronized sleep, because of physiological similarities to waking The pattern of clear rhythmic alpha activity associated with wakefulness gives way to N1, the first stage of sleep, which is defined by a low-voltage, mixed-frequency pattern. In adults the most reproducible pulse of GH secretion occurs shortly after the onset of sleep in association with the first phase of slow-wave sleep (SWS) (stages III and IV).

Stage 5: REM sleep The final stage of sleep is REM and this is the cycle where we dream. For the narcolepsy-cataplexy subtype, the two most significant and consistent symptoms are excessive daytime somnolence and cataplexy (sudden loss of postural tone that occurs while the patient is awake but is otherwise identical to The stage 1 sleep is the phase where one falls to sleep. Non-REM consists of Stage 1, Stage 2, and Stage 3 while REM sleep is the 4th and final stage of a sleep cycle.
