Key physiological methods for monitoring and measuring changes during sleep include electroencephalography EEG of brain waves , electrooculography EOG of eye movements, and electromyography EMG of skeletal muscle activity.
Simultaneous collection of these measurements is called polysomnography , and can be performed in a specialized sleep laboratory. Non-REM sleep occurs first and after a transitional period is called slow-wave sleep or deep sleep. During this phase, body temperature and heart rate fall, and the brain uses less energy. It is the main occasion for dreams or nightmares , and is associated with desynchronized and fast brain waves, eye movements, loss of muscle tone, [2] and suspension of homeostasis. REM sleep occurs as a person returns to stage 2 or 1 from a deep sleep. Awakening can mean the end of sleep, or simply a moment to survey the environment and readjust body position before falling back asleep.
Internal circadian indicators , along with a successful reduction of homeostatic sleep need, typically bring about awakening and the end of the sleep cycle. During a night's sleep, a small amount of time is usually spent in a waking state. In adults, wakefulness increases, especially in later cycles. Most of this awake time occurred shortly after REM sleep. Today, many humans wake up with an alarm clock ; [19] however, people can also reliably wake themselves up at a specific time with no need for an alarm. Sleep timing is controlled by the circadian clock Process C , sleep-wake homeostasis Process S , and to some extent by the individual will. Sleep timing depends greatly on hormonal signals from the circadian clock, or Process C, a complex neurochemical system which uses signals from an organism's environment to recreate an internal day—night rhythm.
Process C counteracts the homeostatic drive for sleep during the day in diurnal animals and augments it at night. An organism whose circadian clock exhibits a regular rhythm corresponding to outside signals is said to be entrained ; an entrained rhythm persists even if the outside signals suddenly disappear. If an entrained human is isolated in a bunker with constant light or darkness, he or she will continue to experience rhythmic increases and decreases of body temperature and melatonin, on a period that slightly exceeds 24 hours.
Scientists refer to such conditions as free-running of the circadian rhythm. Under natural conditions, light signals regularly adjust this period downward, so that it corresponds better with the exact 24 hours of an Earth day. The circadian clock exerts constant influence on the body, affecting sinusoidal oscillation of body temperature between roughly Circadian rhythm exerts some influence on the nighttime secretion of growth hormone. The circadian rhythm influences the ideal timing of a restorative sleep episode.
REM sleep occurs more during body temperature minimum within the circadian cycle, whereas slow-wave sleep can occur more independently of circadian time. The internal circadian clock is profoundly influenced by changes in light, since these are its main clues about what time it is. Exposure to even small amounts of light during the night can suppress melatonin secretion, and increase body temperature and wakefulness. Short pulses of light, at the right moment in the circadian cycle, can significantly 'reset' the internal clock. Modern humans often find themselves desynchronized from their internal circadian clock, due to the requirements of work especially night shifts , long-distance travel, and the influence of universal indoor lighting.
Conversely, they can have difficulty waking up in the trough of the cycle. Generally speaking, the longer an organism is awake, the more it feels a need to sleep "sleep debt". This driver of sleep is referred to as Process S. The balance between sleeping and waking is regulated by a process called homeostasis. Induced or perceived lack of sleep is called sleep deprivation. Process S is driven by the depletion of glycogen and accumulation of adenosine in the forebrain that disinhibits the ventrolateral preoptic nucleus , allowing for inhibition of the ascending reticular activating system.
Sleep deprivation tends to cause slower brain waves in the frontal cortex , shortened attention span, higher anxiety, impaired memory, and a grouchy mood. Conversely, a well-rested organism tends to have improved memory and mood. There is disagreement on how much sleep debt is possible to accumulate, and whether sleep debt is accumulated against an individual's average sleep or some other benchmark. It is also unclear whether the prevalence of sleep debt among adults has changed appreciably in the industrialized world in recent decades.
Sleep debt does show some evidence of being cumulative. Subjectively, however, humans seem to reach maximum sleepiness after 30 hours of waking up. One neurochemical indicator of sleep debt is adenosine , a neurotransmitter that inhibits many of the bodily processes associated with wakefulness. Adenosine levels increase in the cortex and basal forebrain during prolonged wakefulness, and decrease during the sleep-recovery period, potentially acting as a homeostatic regulator of sleep.
Humans are also influenced by aspects of social time , such as the hours when other people are awake, the hours when work is required, the time on the clock, etc. Time zones , standard times used to unify the timing for people in the same area, correspond only approximately to the natural rising and setting of the sun. In polyphasic sleep , an organism sleeps several times in a hour cycle, whereas in monophasic sleep this occurs all at once.
Under experimental conditions, humans tend to alternate more frequently between sleep and wakefulness i. Bimodal sleep in humans was more common before the industrial revolution. Different characteristic sleep patterns, such as the familiarly so-called " early bird " and " night owl ", are called chronotypes. Genetics and sex have some influence on chronotype, but so do habits. Chronotype is also liable to change over the course of a person's lifetime.
Seven-year-olds are better disposed to wake up early in the morning than are fifteen-year-olds. Monozygotic identical but not dizygotic fraternal twins tend to have similar sleep habits. Neurotransmitters, molecules whose production can be traced to specific genes, are one genetic influence on sleep that can be analyzed. The circadian clock has its own set of genes. The quality of sleep may be evaluated from an objective and a subjective point of view. Objective sleep quality refers to how difficult it is for a person to fall asleep and remain in a sleeping state, and how many times they wake up during a single night.
Poor sleep quality disrupts the cycle of transition between the different stages of sleep. A study by A. Harvey et al. Homeostatic sleep propensity the need for sleep as a function of the amount of time elapsed since the last adequate sleep episode must be balanced against the circadian element for satisfactory sleep. Human sleep-needs vary by age and amongst individuals; sleep is considered to be adequate when there is no daytime sleepiness or dysfunction. Moreover, self-reported sleep duration is only moderately correlated with actual sleep time as measured by actigraphy , [51] and those affected with sleep state misperception may typically report having slept only four hours despite having slept a full eight hours.
Researchers have found that sleeping 6—7 hours each night correlates with longevity and cardiac health in humans, though many underlying factors may be involved in the causality behind this relationship. Sleep difficulties are furthermore associated with psychiatric disorders such as depression , alcoholism , and bipolar disorder. Dysregulation detected by EEG includes disturbances in sleep continuity, decreased delta sleep and altered REM patterns with regard to latency, distribution across the night and density of eye movements. Sleep duration can also vary according to season. By the time infants reach the age of two, their brain size has reached 90 percent of an adult-sized brain; [63] a majority of this brain growth has occurred during the period of life with the highest rate of sleep.
The hours that children spend asleep influence their ability to perform on cognitive tasks. Sleep also influences language development. To test this, researchers taught infants a faux language and observed their recollection of the rules for that language. There is also a relationship between infants' vocabulary and sleeping: infants who sleep longer at night at 12 months have better vocabularies at 26 months. Children need many hours of sleep per day in order to develop and function properly: up to 18 hours for newborn babies, with a declining rate as a child ages.
The human organism physically restores itself during sleep, occurring mostly during slow-wave sleep during which body temperature, heart rate, and brain oxygen consumption decrease. In both the brain and body, the reduced rate of metabolism enables countervailing restorative processes. While awake, brain metabolism generates end products , such as reactive oxygen species , which may be damaging to brain cells and inhibit their proper function. During sleep, metabolic rates decrease and reactive oxygen species generation is reduced, enabling restorative processes.
The sleeping brain has been shown to remove metabolic end products at a faster rate than during an awake state. The brain concentration of glycogen increases during sleep, and is depleted through metabolism during wakefulness. The effect of sleep duration on somatic growth is not completely known. One study recorded growth, height, and weight, as correlated to parent-reported time in bed in children over a period of nine years age 1— It was found that "the variation of sleep duration among children does not seem to have an effect on growth.
It has been widely accepted that sleep must support the formation of long-term memory, and generally increasing previous learning and experiences recalls. However, its benefit seems to depend on the phase of sleep and the type of memory. With regard to declarative memory, the functional role of SWS has been associated with hippocampal replays of previously encoded neural patterns that seem to facilitate long-term memory consolidation.
Reactivation of memory also occurs during wakefulness and its function is associated with serving to update the reactivated memory with newly-encoded information, whereas reactivations during SWS are presented as crucial for memory stabilization. Furthermore, nocturnal reactivation seems to share the same neural oscillatory patterns as reactivation during wakefulness, processes which might be coordinated by theta activity. During sleep, especially REM sleep, humans tend to experience dreams. Dreams often seamlessly incorporate concepts, situations, people, and objects within a person's mind that would not normally go together. They can include apparent sensations of all types, especially vision and movement.
Dreams tend to rapidly fade from memory after waking. Some people choose to keep a dream journal , which they believe helps them build dream recall and facilitate the ability to experience lucid dreams. People have proposed many hypotheses about the functions of dreaming. Sigmund Freud postulated that dreams are the symbolic expression of frustrated desires that have been relegated to the unconscious mind , and he used dream interpretation in the form of psychoanalysis in attempting to uncover these desires.
Counterintuitively, penile erections during sleep are not more frequent during sexual dreams than during other dreams. Neatly, this theory helps explain the irrationality of the mind during REM periods, as, according to this theory, the forebrain then creates a story in an attempt to reconcile and make sense of the nonsensical sensory information presented to it. This would explain the odd nature of many dreams. Using antidepressants , [ clarification needed ] acetaminophen , ibuprofen , or alcoholic beverages is thought to potentially suppress dreams, whereas melatonin may have the ability to encourage them.
Insomnia is often treated through behavioral changes like keeping a regular sleep schedule, avoiding stimulating or stressful activities before bedtime, and cutting down on stimulants such as caffeine. The sleep environment may be improved by installing heavy drapes to shut out all sunlight, and keeping computers, televisions, and work materials out of the sleeping area. A review of published scientific research suggested that exercise generally improves sleep for most people, and helps sleep disorders such as insomnia.
The optimum time to exercise may be 4 to 8 hours before bedtime, though exercise at any time of day is beneficial, with the exception of heavy exercise taken shortly before bedtime, which may disturb sleep. However, there is insufficient evidence to draw detailed conclusions about the relationship between exercise and sleep. Although these nonbenzodiazepine medications are generally believed to be better and safer than earlier generations of sedatives, they have still generated some controversy and discussion regarding side effects. White noise appears to be a promising treatment for insomnia. Obstructive sleep apnea is a condition in which major pauses in breathing occur during sleep, disrupting the normal progression of sleep and often causing other more severe health problems.
Apneas occur when the muscles around the patient's airway relax during sleep, causing the airway to collapse and block the intake of oxygen. When several of these episodes occur per hour, sleep apnea rises to a level of seriousness that may require treatment. Diagnosing sleep apnea usually requires a professional sleep study performed in a sleep clinic, because the episodes of wakefulness caused by the disorder are extremely brief and patients usually do not remember experiencing them.
Instead, many patients simply feel tired after getting several hours of sleep and have no idea why. Major risk factors for sleep apnea include chronic fatigue, old age, obesity, and snoring. Fatal familial insomnia , or FFI, an extremely rare genetic disease with no known treatment or cure, is characterized by increasing insomnia as one of its symptoms; ultimately sufferers of the disease stop sleeping entirely, before dying of the disease. Somnambulism , known as sleepwalking, is a sleeping disorder, especially among children. Low quality sleep has been linked with health conditions like cardiovascular disease , obesity , and mental illness. While poor sleep is common among those with cardiovascular disease, some research indicates that poor sleep can be a contributing cause.
Short sleep duration of less than seven hours is correlated with coronary heart disease and increased risk of death from coronary heart disease. Sleep duration greater than nine hours is also correlated with coronary heart disease, as well as stroke and cardiovascular events. Other aspects of sleep health have been associated with obesity, including daytime napping, sleep timing, the variability of sleep timing, and low sleep efficiency. However, sleep duration is the most-studied for its impact on obesity. Sleep problems have been frequently viewed as a symptom of mental illness rather than a causative factor. We are paying out of pocket for the sleep study since my husband done not have insurance.
My mother in law is helping us with some cash to pay. Why do I need a order if we do not have insurance. Where can I take a sleep apnea test,I dont have any problem,during my sleep,taking a dot fisical,the Dr. I just need a test to prove that Im ok. Can you believe it? Who is responsible for this kind of complains? Health plan My psychiatrist Barbara Morgan sent the referral in. I called Wake Forest someone in billing I think never got back to about cost. How much is it? How can anyone afford a needed sleep study when it cost you an arm and leg just to see a specialist,, Its crazy how its cheaper for people without insurance then it is for people with insurance..
