A person can fall back asleep quickly after an awakening, or they can remain awake for long periods of time. When a person is asked how often they wake up during the night, it is awakenings that they report (not arousals). Awakenings, unlike arousals, are usually perceived by the patient.
Sleep is a behavior observed in all living organisms and is necessary for survival. In rodents, total sleep deprivation results in a large rise in energy expenditure.
Against this background, the question of whether SWS truly has a restorative and refreshing role will be considered, together with the suggestion that enhancing SWS may be of benefit to patients who experience insomnia in its many forms. 8 Together, NREM sleep stages 3 and 4 are often known as slow wave sleep (SWS). 12 However, the exact nature and role of SWS are not clearly understood and there is still much to learn about SWS generation and its physiologic functions.
The deepest stage of non-REM (NREM) sleep, characterized by a larger amount of synchronized slow-wave EEG (brainwave activity) than in other stages. These slow waves are called delta activity. A sleep disorder marked by excessive daytime sleepiness and sometimes cataplexy and other symptoms.
A sleep disorder characterized by leg movements or jerks that typically occur every 20 to 40 seconds during sleep, causing sleep to be disrupted and leaving the person with excessive daytime sleepiness.
A chemical (such as serotonin or norepinephrine) that permits nerve signals to bridge the gap, or synapse, between nerve cells. Neurotransmitters usually excite or inhibit activity in downstream, target neurons.
A resting state in which a person has little consciousness of the environment, low cortical activity, and almost no internal thoughts.
To fully understand sleep-related breathing disorders, their causes and their consequences, These stages of sleep are collectively called “slow wave sleep”.
Not only is it important to get adequate hours of sleep, those hours must be “efficient” sleep for optimal health. Many people with sleep-related breathing disorders rarely dream since they spend little time in REM sleep. Many people who sleep very poorly sleep for long periods of time in a futile attempt to access deeper sleep stages.
Deep sleep. This is where the body gets rest. Building up physical and mental energy.
This sleep fragmentation interferes with the replenishment of the immune system, the production of growth hormone and the regulation of glucose metabolism, among other things.

However, post hoc analysis suggests an interaction between SWS and sleep duration, such that sufficient SWS may tend to prevent adverse effects of mild sleep loss on waking function. The present experiment examined the effects of marked SWS deprivation (SD) for two nights, a control sleep disruption (CD) condition in which minutes of SWS were preserved, and a no sleep disruption (ND) condition. In addition, neither SD nor CD caused declines in performance or mood. Daytime sleepiness was assessed with the multiple sleep latency test (MSLT) and performance was evaluated with the simulated assembly line task (SALT), neither of which was used in previous studies of SWS or Stage 4 sleep deprivation. Slow-wave sleep (SWS) has been theorized to be an intense form of nonREM sleep, but selective deprivation of SWS or Stage 4 sleep has not been shown to cause greater decrements in alertness or performance, compared to deprivation or disruption of the other stages of sleep. In agreement with prior studies, two nights of SD did not cause greater daytime sleepiness than did CD, although sleepiness in both conditions was increased compared to the ND condition.
